Note the operational organization on the site. Report your arrival to site management. Ask for the personnel authorised to issue instructions.

Familiarise yourself with the location and operation of the fire extinguishers on every site.

Note the fire alarm and fire fighting facilities on the site.

Should the operating behaviour of the truck crane change in such a manner that the safety conditions are affected, e.g. if you doubt the truck crane is operating safety, stop the machine immediately and inform the appropriate responsible persons.

Do not make any changes to the programmable control systems (e.g. the SLI).

Do not modify or mount attachments to the truck crane without the consent of the manufacturer, if such changes could affect the safety of the unit. This also applies to – installing safety devices, – adjusting safety devices and valves.

Welding work on load-bearing parts may only be conducted by properly qualified personnel following authorisation by the manufacturer. To avoid any damage, especially to electronic parts, there are certain steps you must take before doing any welding work. So always consult GROVE Customer Service before doing any welding work.

Ensure that both the prescribed periods and the periods specified in the operating and maintenance instructions for regular testing, inspection and maintenance work are maintained.

Replace the hydraulic hose lines in the prescribed intervals or have them replaced, even if no safety defects are noticeable.

Replacement parts must fulfil the technical requirements prescribed by the manufacturer. Genuine spare parts always meet these requirements.

Important information 1.6 Safety instructions for truck crane work

1.6

Safety instructions for truck crane work Carefully select a safe site for the truck crane to stand from where you can safely work.

Walk around the truck crane before beginning crane work. Check the condition of the truck crane carefully using the check lists in the operating instructions. Do not assume that everything is in working order simply because it was in working order when work was last completed.

Before commencing work with the crane, check daily that all covers and safety devices are correctly fitted and in an acceptable condition.

Check the safety devices each day before beginning work (SLI, lifting limit switch, dead man’s switch, emergency stop switch for crane control).

When doing rigging or maintenance work above head height, use the intended climbing aids. Do not use machine parts as limbing aids.

Step only on those machine parts which are equipped with appropriate steps and railings and therefore guarantee safety. During rigging and maintenance work on machine sections above body height which have no apparatus for walking, use the extendable ladder which accompanies the machine (e.g. when reeving the hoist cable on the boom nose).

Keep all handles, steps, step treads and ladders free of dirt, snow and ice.

Check all operating and control elements in the crane operator’s cab before starting the crane engine.

Monitor all warning and indicator lamps as well as the control instruments when the engine is started!

Make sure that there are no unauthorised people in the vicinity of or on the truck crane when rigging or during crane work. Secure the danger zone using cordons and label them as such.

When lifting a load, raise the boom to balance out the increase in radius caused by the boom bending so that the load is lifted up when in a vertical position and does not drag, injure helpers or fall into the hoist rope diagonally (e.g. from a vehicle or scaffold). Inform banksmen and helpers about this as well.

Ensure that the truck crane is horizontally aligned before carrying out crane work.

Support the truck crane with the supporting span for the current rigged counterweight before turning the superstructure.

Important information 1.6 Safety instructions for truck crane work

Only use equipment (counterweight sections, lattice extensions) that belongs to your truck crane. The serial number of both the truck crane and the equipment must be identical.

Simultaneously lifting loads with two cranes is particularly dangerous. Use extreme caution when carrying out this type of work.

Always put down the load before you stop work.

Lock the truck crane when you leave the cab to prevent unauthorised use.

04.07.2002

Crane work carried out in the vicinity of supply lines such as oil, gas and power lines is dangerous and requires that special precautionary measures be taken. Please refer to the section titled Crane operation under special operating conditions in the Safety manual and note the relevant national regulations.

Two-stage swing-away lattice extension

H 3.1

The correct designation “two-stage swing-away lattice extension” is in this chapter substituted with the designation “lattice extension” in order to improve readability.

Operating and display elements If the GMK 6220-L is rigged with a two-stage swing-away lattice extension, certain operating and display elements in the crane cab are also applicable to operating the lattice extension.

This section describes all operating and display elements required for the operation of the lattice extension.

Furthermore, this chapter describes the operating elements located directly on the lattice extension.

Two-stage swing-away lattice extension 3.2 Identification

3.2

Identification The two-stage swing-away lattice extension is designed for the truck crane with which it was delivered. The two-stage swing-away lattice extension parts belonging to the truck crane have the same serial number as the truck crane.

The following parts are identified by the serial number: – the 12.5 m (41 ft) section on the fixed section, – the 12.5 m (41 ft) section on the luffing section,

S H

Operate only two-stage swing-away lattice extension sections which have the same serial number as the crane.

The SLI is only set for this two-stage swing-away lattice extension.

This prevents malfunctions and damage.

For technical reasons a truck crane may only be set with one two-stage swing-away lattice extension.

If you wish to use the two-stage swing-away lattice extension on several GROVE truck cranes, the two-stage swing-away lattice extension sections must be adjusted for the corresponding cranes and labelled with all of the respective serial numbers.

The two-stage swing-away lattice extension should only be adjusted by your local GROVE Customer Support!

Description of rigging work

3.6.1

Preparing the truck crane for rigging

Requirements for rigging

Before you rig a two-stage swing-away lattice extension, the following requirements must be met: – The two-stage swing-away lattice extension is attached to the side of the main boom and is in transport condition.

– The counterweight version required acc. to the Lifting capacity table for the planned operation when the lattice extension is rigged.

– The truck crane is supported with the prescribed outrigger span for the planned operation with the lattice extension according to the Lifting capacity table and is aligned horizontally.

– The main boom is completely retracted (0/0/0/0/0) and has been lowered into horizontal position.

– If the truck crane is equipped with two hoists with additional equipment, the hook block is unreeved on the hoist which is not used for working with the lattice extension.

Requirements for unrigging

Before you lower a two-stage swing-away lattice extension into a horizontal position, the following requirements must be met: – No other load is raised outside the hook block.

– The required counterweight version for operation with the rigged lattice extension according to the Lifting capacity table is rigged.

– The truck crane is supported with the outrigger span prescribed for operation with the rigged lattice extension according to the Lifting capacity table.

– The main boom is fully retracted (0/0/0/0/0).

– The lattice extension is raised completely.

– The SLI code is entered for operation with the rigged lattice extension.

If these requirements are met, lowering into the horizontal position with lattice extension/boom extension and a slewing range of 360° is permitted and Raising the setting down the main boom with rigged is monitored by the SLI; lattice extension, p. 3 - 77.

3.6.2

Checking the transport condition For transportation you must establish certain connections between both parts of the lattice extension. The connections which need to be established depend on whether the lattice extension: – is folded up at the side of the main boom for transportation or – is completely removed for transportation.

Transport condition is when the lattice extension has been removed as described in the corresponding checklists.

S

Be careful not to damage the lattice extension and the main boom!

Always put the lattice extension into transport condition before driving the truck crane with a lattice extension folded at the side or working with the main boom.

Only then is the lattice extension secured against slipping.

In this way you prevent the partly fastened lattice extension hitting the main boom or the individual components of the lattice extension hitting each other and becoming damaged.

You must check transport condition: – After unrigging the lattice extension, before you drive the truck crane with the lattice extension folded at the side or work with the main boom.

– Before installation and before rigging the lattice extension.

The corresponding checklists require that the lattice extension is in transport condition.

Hose drum for hydraulic supply The hydraulic supply for the lattice extension is via a hose drum on the lefthand side of the main boom.

Depending on the driving mode of the truck crane the hose drum must be removed for on-road driving with a maximum axle load of 12 t; GMK 6220-L operating instructions, Part 1, Chapter Driving with the truck crane, Section Checking the truck crane before driving – Driving mode table.

à

When working with the main boom for longer the hydraulic connection between the hose drum and the main boom head should be disconnected.

This prevents the unnecessary reeling and unreeling of the hose.

à

Locking device for transportation

The hose drum is equipped with a locking device. The locking device prevents the hose drum twisting unchecked against the holder when releasing the strain relief because of initial tension.

You must always insert the locking device before releasing the strain relief (1) from the holder (2) on the main boom.

04.07.2002

You may release the anti-twist device only after you have attached the strain relief (1) back in the holder (2) on the main boom.

Operating instructions lattice extension GMK 6220-L

Two-stage swing-away lattice extension 3.6 Description of rigging work

S

Risk of accidents from unchecked turning hose drum!

You may release the anti-twist device only when you have attached the strain relief on the main boom beforehand.

By doing this you prevent the hose drum twisting unchecked against the holder and the turning hydraulic hoses injuring other people.

There are eight bores (1) above the radius on the inner flanged wheel (2) of the hose drum.

Inserting anti-twist device

• Turn the hose drum until a bore is in front of the spring latch (3).

• Move the spring latch into the bore, the hose drum is secured against twisting.

Removing anti-twist device

• Attach the strain relief on the main boom before removing.

• Withdraw spring latch (3) from the bore in the flanged wheel.

Installing hose drum

If the hose drum has been removed for on-road driving, you must re-install it before working with the lattice extension.

• Attach the hose drum to the recesses (1) with an auxiliary crane.

• Lift the hose drum onto the left side of the main boom.

• First move the upper threaded pins (6) diagonally from below into the retaining sheets (5).

• Then swing the hose drum down onto the main boom so that the lower threaded pins (3) slide into the retaining sheet (2).

• Insert the spacer sheets (4).

• Attach the hose drum by turning the nuts on the threaded pins (3) and (6).

Removing hose drum

Before removing the hose drum the hydraulic connection to the hose drum must be disconnected.

• Insert the locking device; à Locking device for transportation, p. 3 - 38.

• Attach the hose drum to the recesses (1) with an auxiliary crane.

• Unscrew the nuts from the threaded pins (3) and (6).

• Remove the spacer sheets (4).

• Swing the hose drum down from the main boom so that the threaded pins (3) slide out of the retaining sheet (2).

• Lower the hose drum until the upper threaded pins (6) are no longer in the bores of the retaining sheet (5).

• Lift the hose drum off the main boom and place it on a separate vehicle.

Hydraulic connection

Risk of accidents from hydraulic hoses springing back!

If you release the strain relief after the locking device has been released, you must not let go of the strain relief until it is attached again.

If you let go of the strain relief, the hydraulic hoses will spring back because of the spring force in the hose drum and may injure people or damage parts of the truck crane.

04.07.2002

G

Folding out/in the deflection sheaves on the 12.5 m (41 ft) section To prevent the hoist rope dragging on the main boom or lattice extension during operation with the lattice extension or boom extension, the hoist rope is guided via deflection sheaves.

On the 12.5 m (41 ft) section there is a deflection sheave at the rear (1) and a deflection sheave at the front (2).

Both sheaves must be folded out:

– for operation with the 13 m (43 ft) swingaway lattice extension,

– for operation with the 22 m (72 ft) two-stage swing-away lattice extension.

For transportation both deflection sheaves must be folded in.

H

G H

The information in this section also applies to raising and setting down the main boom with a rigged boom extension.

Risk of overturning with a reeved hook block on the main boom head!

If an SLI code has been entered for work with the lattice extension, the load is measured via pressure sensors on the lattice extension.

An additional load is not detected on the main boom here.

Therefore unreeve the hook block on the main boom head before working with the lattice extension. This prevents the SLI calculating with the wrong values and the truck crane tilting before the SLI switches off.

To raise and set down the main boom with a rigged lattice extension the main boom must be fully retracted because the SLI then automatically switches to the rigging program.

To raise and set down the following requirements must be met:

11==

– The SLI code for the actual rigging mode is set on the SLI with the 13 m (43 ft) swing-away lattice extension or 22 m (72 ft) two-stage swing-away Operating instructions GMK 6220-L, part 2, chapter lattice extension; Crane operation, Section Operating the safe load indicator – Setting rigging mode.

3.7.1

Telescoping with rigged lattice extension

S H

The main boom may be overloaded!

If you telescope the main boom with a rigged lattice extension or boom extension, you must not rotate the superstructure at the same time.

This prevents the main boom being subject to additional side forces and increased vibration and possibly becoming overloaded.

The information in this section also applies to telescoping with a rigged boom extension.

Telescoping with a load is released by the SLI only for loads which are below the values of the rigging programs.

Telescoping with a rigged lattice extension is released by the SLI only if the main boom is raised to an angle of approx. 75° - 80° (the exact angle deRigging programs in the lifting pends on the length of the lattice extension; capacity table).

If the main boom angle is too small for telescoping with the rigged lattice extension angle, the SLI shows the corresponding error message.

à

• Put down the load.

• Raise the main boom to an angle necessary according to the rigging pro-

à Rigging programs in the lifting capacity table).

gram (

• Telescope the main boom to the required length and observe the hook block when doing so; lower and raise it using the hoist.

Do not actuate the slewing gear when telescoping.

3.7.2

Operation with the lattice extension

If a hook block is reeved on the main boom during operation with the lattice extension, the loads given in the Lifting capacity tables decrease. The values which must be taken from the load capacities depend on the length of the lattice extension and the weight of the hook block and are entered in their own table in the Lifting capacity tables.

G H SLI shutdown

Risk of overturning with a reeved hook block on the main boom head!

If an SLI code has been entered for work with the lattice extension, the load is measured via pressure sensors on the lattice extension. An additional load is not detected on the main boom here.

Always determine the reduced load for the current rigging mode (given load minus value for the reduction with a reeved hook block) and lift only loads which are in accordance with the maximum reduced load.

This prevents the SLI calculating with the wrong values and the truck crane tilting before the SLI switches off.

The hoisting, lowering, slewing, derricking and telescoping movements of the main boom are done in the same way as when operating with the main boom. Telescoping is permitted only at main boom angles of approx. 75 Rigging 80°, depending on the length of the lattice extension (exact value programs in the Lifting capacity table).

à

When working with the 13 m (43 ft) swing-away lattice extension or the 22 m (72 ft) two-stage swing-away lattice extension, operation is always monitored by the SLI. SLI shutdowns can occur during lattice extension operation for the same Operating instructions GMK 6220reasons as with main boom operation; L, part 2, chapter Crane operation, Section Operating the safe load indicator – During crane work.

à

The angle of the lattice extension is also monitored and if the permitted angle of the lattice extension is not adhered to, the SLI switches off and shows a corresponding error message.

Procedure if the permissible wind speed is exceeded

Strong winds can overstrain the truck crane. Closely observe therefore the Operating instructions instructions in the Effect of wind on crane operation, GMK 6220-L, part 2, chapter Crane work with the main boom – External influences during crane operation.

Two-stage swing-away lattice extension 3.8 Turning loads with the two-stage swing-away lattice extension

3.8

Turning loads with the two-stage swing-away lattice extension When turning loads it is necessary to employ a two-hook operation.

The only type of two-hook operation technically possible and protected by the SLI is described in this chapter using the turning of loads as an example.

G G H 3.8.1

Risk of accidents due to overloading!

Lifting a load with two hooks is permissible only if the following instructions and illustrations are observed!

If these instructions are not observed, accidents could occur due to individual parts of the truck crane being overloaded! The SLI then no longer gives protection.

Two-hook operation with the two-stage swing-away lattice extension is not permitted!

Risk of accidents due to overloading!

The load must always be lifted completely with the weakest part first (lattice extension).

You can find the position and function of the required operating instruments in the supplied GMK 6220-L Operating Instructions.

Requirements The following description requires that: – the main hoist rope is reeved on the main boom and

04.07.2002

– the auxiliary hoist rope is reeved on the two-stage swing-away lattice extension and

G

– the lifting limit switches for both hoisting gears are connected.

Risk of accidents due to overloading!

The reeving on the main boom must be equal to or greater than that on the lattice extension!

If this condition is not fulfilled, the main hoist rope and main hoisting gear will become overloaded.

Turning load

S H H

To turn loads, proceed only in the manner described as follows.

Danger of accidents due to overloading!

Acceleration forces are an additional load on the crane.

For this reason, move the load during two-hook operation at the lowest possible speed! This prevents parts of the crane (two-stage swing-away lattice extension) from being overloaded.

If the load is on two hooks, there will be slight differences in the Actual load display. However, the differences are on the safe side with regard to SLI deactivation.

If the load is on two hooks, you must not change the SLI code to Operation with main boom; it must be set to Operation with the lattice extension throughout the lifting process.

C0183

• Lift the load fully with the lattice extension.

• Only now should you attach the load to the hook block of the main boom

3.9

Driving with rigged crane and two-stage swing-away lattice extension installed This section describes how to move the truck crane with an installed counterweight and rigged two-stage swing-away lattice extension on the building site.

G G 3.9.1

Risk of accidents!

It is forbidden to move the truck crane with a suspended load.

Put the load down before you move the truck crane.

Secure the hook block so that it cannot swing.

Risk of overturning!

Before a rigged crane can be driven the superstructure must be locked and the slewing gear permanent brake must be engaged.

Driving route The route must be a flat, even surface. The level adjustment system cannot compensate for uneven surfaces. If the surface pressure of the tyres exceeds the permissible load on the ground, the surface pressure must be increased using packing made of durable material (e.g. wooden planks).

à

04.07.2002

S

Risk of tyre damage!

Check the pressure in the tyres before the rigged truck crane is moved!

The truck crane may only be moved if the tyres have been inflated to the GMK 6220-L operating instructions, Part 2, Chapter required air pressure; Technical information, Section Carrier – Tyres.

Do not reduce the tyre pressure!

4.6.1

Turning loads Turning loads requires working with two-hook operation. Two-hook operation is permitted only in conjunction with a lattice extension.

The only kind of two-hook operation technically possible and safe due to SLI is described in this chapter using turning of loads as an example.

G G H Prerequisites

Risk of accidents due to overloading!

Hoisting loads with two hooks is only permissible if carried out according to the following instructions and diagrams!

If these instructions are not observed there is a risk of accidents due to overloading of individual truck crane parts. In that case, protection by means of SLI will not be possible.

Two-hook operation with the auxiliary single-sheave boom top is not permitted!

Risk of accidents due to overloading!

The load must always be raised completely starting with the weakest part (auxiliary single-sheave boom top).

Regarding position and function of necessary operating instruments; Operating instructions GMK 6220-L operating instructions, Part 2, Chapter Description of the truck crane – crane section, Section Functional description of the display and operating instruments.

Risk of accidents due to overloading!

The reeving on the main boom must be the same as or larger than the reeving on the auxiliary single-sheave boom top.

If this prerequisite is disregarded the main hoist rope and the main hoist will get overloaded.

Setting the SLI

H C

For the two-hook operation both hoists on the SLI need to be switched on.

It is recommendable to enter the reevings for both hoists right at the beginning. The values are saved and called up directly when changing over the hoists. This saves you entering the values during operation. Proceed as follows:

• Switch off both hoists.

To do so press down the bottom part of the two rocker switches Disconnect auxiliary hoist and Disconnect main hoist.

• Switch on main hoist.

To do so press top half of rocker switch Disconnect main hoist.

On the Hoists indicator lamps lamp I for the main hoist lights up.

• On the Reeving display, enter the number of reeved ropes of the main hoist

rope on the main boom.

Now the reeving for the main hoist is stored and you can change over to the auxiliary hoist.

Cü

• Switch off both hoists.

To do so press down the bottom part of the two rocker switches Disconnect auxiliary hoist and Disconnect main hoist.

Switch on auxiliary hoist.

To do so press top half of rocker switch Disconnect auxiliary hoist.

• On the Reeving display, enter the number of reeved ropes of the auxiliary hoist rope on the auxiliary single-sheave boom top.

Now the reeving for the auxiliary hoist is also stored and you can connect the main hoist.

11==

• Set the SLI code for operation with auxiliary single-sheave boom top valid for the truck crane’s current installation condition.

The SLI for two-hook operation is now set; it considers the reeving for the auxiliary hoist and the lifting capacity tables for the auxiliary single-sheave boom top.

H Turning the load

S

For turning the load, proceed as follows.

Danger of accidents due to overloading!

Acceleration forces are an additional load on the crane.

For this reason, move the load during two-hook operation at the lowest possible speed! This prevents parts of the crane (two-stage swing-away lattice extension) from being overloaded.

As soon as the load is attached to two hooks, there will be slight variations in the Actual load display. These variations are on the safe side in terms of SLI, though.

As long as the load is attached to two hooks do not switch the SLI code to Operation with main boom; rather it must be set at Operation with auxiliary single-sheave boom top during the entire hoisting procedure.

04.07.2002

H H

Load measurement for two-hook operation is carried out via the pressure in the derricking cylinder of the main boom. This reduces the loads listed in the Lifting capacity table by the weight of both reeved hook blocks.

Boom extension

5.1

Components and Identification

5.1.1

Identification The boom extension consists of the 22 m (72 ft) two-stage swing-away lattice extension and two boom extension sections.

The boom extension is designed for the truck crane with which it was delivered. The parts of the boom extension belonging to the truck crane have the same serial number as the truck crane.

All components are identified by serial number.

Both parts of the boom extension are identified by a serial number.

S H

For technical reasons the truck crane may be adjusted only with one boom extension.

If you wish to use the boom extension on several GROVE truck cranes, the parts of the boom extension must be adjusted for these cranes and labelled with all of the respective serial numbers.

Danger of damage if the boom extension has not been adjusted or if it has been incorrectly adjusted!

Have the matching of the boom extension carried out only by GROVE Customer Support at the particular location!

s

04.07.2002

S

Danger of malfunction and damage!

Operate the truck crane only with those parts of the boom extension which have the same serial number as the crane.

The SLI is set only for this boom extension.

This means that you can prevent malfunctions and damage.

Driving with rigged crane and boom extension This section describes how to move the truck crane with an installed counterweight and rigged two-stage swing-away lattice extension on the building site.

G G 5.6.1

Risk of accidents!

It is forbidden to move the truck crane with a suspended load.

Put the load down before you move the truck crane.

Secure the hook block so that it cannot swing.

Risk of overturning!

Before a rigged crane can be driven the superstructure must be locked and the slewing gear permanent brake must be engaged.

Driving route The route must be a flat, even surface. The level adjustment system cannot compensate for uneven surfaces. If the surface pressure of the tyres exceeds the permissible load on the ground, the surface pressure must be increased using packing made of durable material (e.g. wooden planks).

à

04.07.2002

S

Risk of tyre damage!

Check the pressure in the tyres before the rigged truck crane is moved.

The truck crane may only be moved if the tyres have been inflated to the Operating instructions GMK 6220-L, Part 2, Chapter required air pressure; Technical information, Section Technical data – Carrier – Tyres.

Do not reduce the tyre pressure!

Danger of accidents due to overridden SLI! The position required for the main boom and lattice extension in order to move the crane is partly outside the permitted working range. You should therefore always enter the appropriate Telescoping rigging code or Derricking rigging code before carrying out the corresponding crane movements.

Never override the SLI.

Lifting limit switch on the heavy load lattice extension The functions Raise hoist, Extend main boom, Lower main boom and Lower lattice extension are monitored during operation with the heavy load lattice extension by the lifting limit switch on the lattice extension and are switched off when the lifting limit switch is actuated.

When operating with the heavy load lattice extension, there are two possibilities for lifting limit switch connections: – When using the main and auxiliary hoist, a lifting limit switch must be connected to both the main boom and the heavy load lattice extension in order to monitor the function of both hoist units.

– If using the auxiliary hoist only, the connection on the main boom is overridden.

Danger of damage to electrical connections!

Always disconnect the electrical connections to the lattice extension before slewing onto the main boom basic section.

In this way, you avoid damaging the electrical connections to the lattice extension while slewing.

For operation with the heavy load lattice extension, you must override the lifting limit switch connection on the main boom.

Risk of accidents if the chain hoist should fall off!

Always detach the chain hoist for setting working positions before operating with the heavy load lattice extension.

In this way you will avoid damaging the main boom with the chain hoist or causing injury should the hoist drop.

If a heavy load lattice extension is reeved during operation with the main boom, the loads given in the Lifting capacity tables decrease. The values which have to be taken off the loads are given in the Lifting capacity tables in their own table.

The hoisting, lowering, slewing, derrick and telescoping movements are done in the same way as when operating with the main boom. Telescoping, however, is cleared by the SLI only for main boom angles below 60° or 80° Rigging programs in the lifting capacity table). (for exact value see

The SLI monitors operation when working with the heavy load lattice extension.

SLI shutdown can occur with heavy load lattice extension operation for the same reasons as when operating with the main boom; Operating instructions GMK 6220-L, Part 2, Chapter Crane operation, Section Operating the safe load indicator – During crane operation – SLI shutdown.

Telescoping with rigged heavy load lattice extension The main boom may become overloaded!

While you are telescoping the main boom with the rigged heavy load lattice extension, you may not simultaneously slew the superstructure.

This prevents the main boom being subjected to additional side forces and increased vibration and becoming overloaded.

Telescoping with a load is released by the SLI only for loads which are below the values in the rigging programs.

Telescoping with a rigged heavy load lattice extension is released by the SLI Rigging program in the if the main boom is derricked in below 60° or 80° ( lifting capacity table).

If the main boom angle is too small for telescoping with the rigged lattice extension angle, the SLI displays the corresponding error message.

• Set down the load.

• Derrick in the main boom by the appropriate angle according to the rigging program (

Turning loads When turning loads it is necessary to employ a two-hook operation. Twohook operation is permitted only in conjunction with a lattice extension.

The only type of two-hook operation technically possible and protected by the SLI is described in this chapter using the turning of loads as an example.

G

Risk of accidents due to overloading!

Lifting a load with two hooks is permissible only if the following instructions and illustrations are observed!

If these instructions are not observed, accidents could occur due to individual parts of the truck crane being overloaded! The SLI then no longer provides protection.

Two-hook operation with the heavy load lattice extension is not permitted!

G

Risk of accidents due to overloading!

The load must always be lifted completely with the weakest part first (heavy load lattice extension).

H Prerequisites

Regarding position and function of necessary operating instruments; GMK 6220-L operating instructions, Part 2, Chapter Description of the truck crane, Section Functional description of the display and operating elements.

The following description requires that – the main hoist rope is reeved on the main boom and

04.07.2002

– the auxiliary hoist rope on the heavy load lattice extension is reeved.

G

Risk of accidents due to overloading!

The reeving on the main boom must be equal to or greater than that on the heavy load lattice extension!

If this condition is not fulfilled, the main hoist rope and main hoisting gear will become overloaded.

It is advisable to enter the reevings for both hoists at the start. The values are stored and called up directly when switching hoisting gears. This eliminates the need for input later during operation. Proceed as follows:

• Switch off both hoists.

To do this, press down both rocker switches Auxiliary hoist shutdown and Main hoist shutdown.

• Switch the main hoist on by pressing the Main hoist shutdown rocker switch up.

On the display lamps Hoists, lamp II is now lit for the auxiliary hoist and lamp I is flashing for the main hoist.

11==

• Set the SLI code for crane operation with the heavy load lattice extension, valid for the current rigging mode of the truck crane.

Now the SLI is set for two-hook operation; this takes into account the reeving for the auxiliary hoist and the lifting capacity table for the heavy load lattice extension.

H Turning a load

04.07.2002

S H H

The load measurement is taken in two-hook operation via the pressure in the main boom’s derricking cylinder. The loads detailed in the Lifting capacity table then decrease by the weight of both reeved hook blocks.

To turn loads, proceed only in the manner described as follows.

Danger of accidents due to overloading!

Acceleration forces are an additional load on the crane.

For this reason, move the load during two-hook operation at the lowest possible speed! This prevents parts of the crane (two-stage swing-away lattice extension) from being overloaded.

If the load is on two hooks, there will be slight differences in the Actual load display. However, the differences are on the safe side with regard to SLI shutdown.

As long as the load is hanging on two hooks, you may not switch the SLI code to Operation with the main boom. It must be set to Operation with the heavy load lattice extension during the entire lifting procedure.
