à GMK 6300L operating man-

Safety instructions for working with the lattice extension The operation of GMK 6300L with one of the lattice extensions described in these operating instructions is subject to: – all the safety instructions contained in the operating instructions supplied with the GMK 6300L and – all the following safety instructions.

Use the appropriate access aids when carrying out overhead rigging or maintenance work. Do not use parts of the crane as access aids.

Walk only on those machine parts which are equipped with appropriate platforms and railings and therefore guarantee safety. During rigging and maintenance work on machine parts above body height which have no device for accessing them, always use the extendable ladder supplied (e.g. when reeving the hoist rope on the boom head).

If there is a risk of falling when doing work on the truck crane, suitable equipment must be used to prevent this (e.g. ladder, lifting platform, auxiliary crane).

If the risk of falling cannot be minimised despite using such equipment, you must ensure the safety of yourself and any assisting personnel by using approved fall prevention systems.

The points at which the fall prevention safety system can be attached to on the truck crane are indicated with the symbol shown here.

Basic safety instructions 2.5 Safety instructions for working with the lattice extension

Make sure that there are no unauthorized people in the vicinity of or on the truck crane when rigging or during crane work. Cordon off the danger zone clearly and mark the zone as such.

Only use parts of equipment (counterweight sections, lattice extension) that belong to your truck crane. Both the truck crane and the equipment must have the same serial number.

Lifting loads simultaneously with two cranes is particularly dangerous.

Carry out this type of work with special care.

Secure the truck crane against unauthorized use whenever you leave it.

Always secure the pins both in the connecting points and in the holders using retaining pins. This prevents unsecured pins from coming loose, falling out and causing injuries.

Observe the centre of gravity information when slinging and use suitable slinging material.

In this way, you prevent the attached sections from slipping out, falling and causing injury during installation or removal.

When the swing-away lattice is folded onto the main boom for transport, it must be secured in the slewing connection with a pin.

Otherwise the swing-away lattice can swing out by itself if the hydraulics of the swivel ram is damaged.

If this happens, the permissible vehicle will be exceeded.

20.10.2016

Crane work carried out in the vicinity of live electrical cables as well as oil, gas or other supply lines is dangerous and requires that special precautionary measures be taken. Please observe the instructions in the section titled Crane operation under special operating conditions in the Safety manual and the respective national regulations.

Swing-away lattice 4.1 Short description of the operating elements

4

Swing-away lattice The swing-away lattice is also a part of the boom extension. For this reason, the descriptions here also refer to the boom extension under certain conditions.

Then, instead of the expression swing-away lattice, the collective term lattice extension is used.

H

The lifting capacity tables primarily contain the term swing-away lattice extension. This term will only be used later in this chapter, when a length specification is necessary.

When no length data is necessary (e.g. for rigging work), the term swingaway lattice is only used when the text needs to be as short as possible.

Description of rigging work

4.3.1

Securing the swing-away lattice with a rope For certain alignments of the truck crane, the swing-away lattice can swing around by itself when the last connection to the main boom is removed.

G

There is a risk of accidents due to the swing-away lattice swinging of its own accord.

Always secure the swing-away lattice with a guide rope on the main boom before disconnecting anything.

This will prevent the swing-away lattice from swinging around of its own accord and pushing you off the crane base or causing injury to you or other persons.

Secure the swing-away lattice in the following manner:

• Attach a rope (2) at the front of the swingaway lattice.

• Guide the rope underneath the swing-away lattice, over the rope guide (1) on the main boom and back again.

• Have a helper hold the rope tight while you are releasing the last connection.

20.10.2016

H

If you are alone, secure the other end of the cord on the crane (depending on the slewing direction of the superstructure, e.g. on the rear right on the outrigger beam or on the left on the steps of the access ladder to the carrier).

Swing-away lattice 4.3 Description of rigging work

4.3.2

To check whether the swing-away lattice is secured for transport For transport, certain connections must be made between the sections of the swing-away lattice, depending on whether the swing-away lattice: – is folded up against the main boom for transport or – is removed for transportation.

S G

There is a risk of damage to the lattice and the main boom.

Always secure the swing-away lattice for transport before driving the truck crane with a folded swing-away lattice or working with the main boom.

Only then is the swing-away lattice secured against slipping.

This way you prevent the partly fastened swing-away lattice from hitting the main boom or the individual components of the swing-away lattice from hitting each other and becoming damaged.

Risk of accidents if the permissible vehicle is exceeded.

When the swing-away lattice is folded onto the main boom for transport, it must be secured in the slewing connection with a pin.

Otherwise the swing-away lattice can swing out by itself if the hydraulics of the swivel ram is damaged.

If this happens, the permissible vehicle will be exceeded.

Check that the swing-away lattice is secured for transport: – After unrigging the swing-away lattice, before you drive the truck crane or work with the main boom.

– After unrigging the swing-away lattice, regardless of whether you drive the truck crane, work with the main boom or whether the swing-away lattice has been removed.

20.10.2016

– Before installation and before rigging the swing-away lattice.

The corresponding checklists require that the swing-away lattice be secured for transport.

Position of the hydraulic connections Before operating the lattice extension, you must ensure the hydraulic connections are in the lattice extension operation position.

Before working with the main boom for longer periods of time, you must place the hydraulic connections in the Main boom operation position, so that the hoses are not put under unnecessary strain.

G G Working with the lattice extension

Risk of accidents from hoses springing back If you detach the hoses after the locking device has been released, do not under any circumstances let go of the hoses before they has been re-secured. Otherwise the hoses will retract uncontrollably and can injure people or damage parts of the truck crane.

There is a risk of an accident when pulling sideways.

When you are standing on the ladder, you will have to pull the hoses. You may fall from the ladder doing this. Make sure that the ladder is positioned securely.

The locking device on the hose drum must be released;

à p. 4 - 47.

The raising, lowering, slewing, derricking and telescoping movements are carried out in the same way as when operating with the main boom. This section only contains information that you will need for a rigged or installed swing-away lattice.

4.4.1

Setting the SLI

H Entering the SLI code

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 and the SLI subsequently switches off earlier.

The values which must be deducted from the load capacities depend on the length of the lattice extension and the weight of the hook block. You will find a table with the values in the lifting capacity tables in the section Information on working with the swing-away lattice extension.

• Enter the current rigging mode on the SLI, either using the corresponding SLI code according to the lifting capacity table or using the individual components.

When operating with the swing-away lattice you must also enter the length of the swing-away lattice.

• Enter the current reeving at the SLI. • Check whether the current rigging mode of the truck crane corresponds to the displayed rigging mode.

Derricking the main boom Risk of accidents if the SLI is overridden!

Do not override the SLI when lowering the boom into a horizontal position.

If the SLI is overridden, the crane operations will not be monitored and the truck crane will overturn if you leave the permissible working range.

If the following requirements are met, lowering into the horizontal position with swing-away lattice and a slewing range of 360° is permitted and is monitored by the SLI. – The current rigging mode with the rigged swing-away lattice is entered on the SLI, and the corresponding SLI code is displayed as per the Lifting capacity table.

– The current reeving type on the swing-away lattice is entered for the hoisting gear whose hoist rope is reeved on the swing-away lattice.

– Apart from the hook block, there is no load on the swing-away lattice.

– The main boom is fully retracted.

The SLI will only release the main boom for raising and setting it down when the main boom is completely retracted.

20.10.2016

When all of the above requirements have been satisfied, the SLI will automatically switch to the rigging tables and derricking can then be done in the angle range underneath the working range of approx. 15°.

telescoping with rigged heavy load lattice extension

Slewing range of 360°

S

Risk of overloading of the main boom If you are telescoping the main boom with the rigged swing-away lattice, you may not simultaneously slew the superstructure.

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

The telescoping of the main boom with a rigged swing-away lattice is monitored by the SLI. Telescoping will only be enabled if the main boom is derricked to a certain angle and a maximum permissible load is not exceeded.

The required angle (between 75° and 78°) depends on the rigging mode of the truck crane.

You will find the required main boom angle and the maximum permissible load (weight of the hook block) in the Lifting capacity tables.

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

The telescoping mechanism is operated in the same way as the main boom;

à GMK 6300L operating manual.

Span of 6.30 x 8.70 m

Risk of overturning backwards!

Given a span of 6.30 x 8.70 m and a lateral main boom position, telescoping is prohibited. There is a risk of overturning backwards.

Do not override the SLI. If the swing-away lattice is rigged into position on the side,

If the main boom angle is too large for telescoping with the swing-away lattice, the SLI displays an appropriate error message.

Raising and lowering

G

You can adjust the sensitivity of the control levers to the operating conditions; GMK 6300L operating manual.

à

Risk of accidents due to unexpected crane movements!

In the case of multiple configuration, check whether the control lever function Derricking is switched on before you move the control lever for derricking.

This way, you avoid accidents due to unexpected crane movements.

To lower:

Push the control lever to the right – the swing-away lattice will be lowered.

To raise:

Push the control lever to the left – the swing-away lattice will be raised.

The maximum derricking speed is automatically reduced as the system length is increased. If you now reduce the working radius (e.g. by retracting the telescoping), the derricking speed is automatically increased again.

Swing-away lattice 4.4 Operation with swing-away lattice

When the swing-away lattice is derricked, the SLI automatically switches to the values specified in the lifting capacity table for fixed angles (5° inclination) and intermediate angles (5-20° or 20-40° inclination) when this is permitted for the load currently being raised.

If this switchover is not permitted for the load currently raised, derricking will be switched off and a corresponding error message will be generated.

The swing-away lattice can be derricked under load. The derricking last is limited; Lifting capacity table. If the limit is exceeded, lowering is deactivated.

Information about the SLI shutdown Operation with the swing-away lattice is monitored by the SLI. When operating with the swing-away lattice, SLI shutdowns may occur for GMK 6300L the same reasons as when operating with the main boom; operating manual.

à

Additional reasons for a shutdown

When operating with a derricking swing-away lattice: – Different lifting capacities are released for the angles 5°, 0-20° and 20 - 40°. Lowering the swing-away lattice can lead to the SLI shutting down when the currently raised load is not permitted in the newly reached angle range.

– For the above-named angles, the swing-away lattice can be derricked under load. If the current load is greater than permitted for the angle range, the lowering of the swing-away lattice is stopped by the SLI. – When the SLI has shut down, the Lower swing-away lattice movement and all other movements which increase the load moment are blocked.

4.4.6

G

Procedure if permissible wind speed is exceeded Risk of accidents due to excessively high wind speeds!

If the current wind speed is higher that the maximum permissible wind speed, stop crane operation immediately and restore the corresponding rigging mode.

This prevents the truck crane from overturning due to overloading.

• Prior to and during crane operation, check whether the actual wind speed is lower than the maximum permissible wind speed.

• Make sure that you follow the instructions for checking the wind speed;

à Lifting capacity table and GMK 6300L operating manual.

If the maximum permitted wind speed is exceeded No automatic shutdown occurs if the maximum permissible wind speed is exceeded.

• Immediately stop crane operations.

Information about the main boom operation when the swingaway lattice is folded/rigged

Folded

This section applies to instances when the swing-away lattice is folded at the side.

If a swing-away lattice is folded at the side during operation with the main boom, the loads given in the Lifting capacity tables decrease.

The relevant formulas and examples for calculating these values during operations planning can be found in the Lifting capacity table.

The decreased values are shown directly on the SLI insert in the Maximum load display (1).

Rigged

S

This section applies when the swing-away lattice is rigged and locked to the main boom head.

Risk of overturning with impermissible rigging mode Main boom operation with a rigged swing-away lattice is only permissible in rigging modes that are also permissible for the rigged swing-away lattice (outrigger span, counterweight, slewing range).

If you set up rigging modes that are only valid for main boom operation without a rigged swing-away lattice (e.g. Free on wheels working position), then the truck crane could overturn during operation.

For operation with the main boom with a rigged swing-away lattice, you must enter the current rigging mode for the main boom without a swingaway lattice on the SLI.

20.10.2016

The values given in the corresponding Lifting capacity table for the lifting capacities and for the permissible wind speeds decrease in this case.

3 302 535 en

Lattice extension operating manual GMK 6300L

Swing-away lattice 4.4 Operation with swing-away lattice

Reduction of the lifting capacity The maximum load display (1) does not show the reduced values.

The SLI also takes into account the load moment affected by the currently rigged swing-away lattice and will correspondingly switch off earlier.

In the Lifting capacity table, you will find table with values for reducing the lifting capacities. The given values for reduction are only maximum values for certain rigging modes (angle and length of main boom and lattice extension).

The SLI, however, takes into account the value for the currently rigged swing-away lattice, adds the weight of the raised load and displays the sum on the Current load display (1).

The displayed value could deviate from the value that was previously calculated during the operations planning.

If this is the case, the SLI is not defective. Do not override the SLI, even if the displayed value is higher than the calculated value.

G 4.4.8

Risk of accidents if the SLI is overridden!

Do not under any circumstances override the SLI. If the SLI is overridden, the crane operations will not be monitored and the truck crane will overturn if you leave the permissible working range.

Risk of overturning when operating with the boom extension!

A hook block must not be reeved on the main boom during operation with the boom extension.

It is prohibited to work with the main boom if the boom extension is rigged.

Risk of accidents due to overloading!

It is prohibited to lift a load with two hooks when the boom extension is rigged.

The raising, lowering, slewing, derricking and telescoping movements are carried out in the same way as when operating with the main boom.

This section only contains information that you will need additionally for a rigged boom extension.

G

Derricking the main boom Risk of accidents if the SLI is overridden!

Do not override the SLI when lowering the boom into a horizontal position.

If the SLI is overridden, the crane operation will not be monitored and the truck crane will overturn if it moves outside of the permissible working range.

If the following requirements are met and the slewing range is 360°, lowering into a horizontal position with the boom extension attached is permitted and monitored by the SLI. – The current rigging mode with the rigged boom extension is entered on the SLI, and the corresponding SLI code is displayed as per the Lifting capacity table.

– The current reeving on the boom extension is entered for the hoisting gear whose hoist rope is reeved on the boom extension.

– Apart from the hook block, there is no load on the boom extension.

– The main boom is fully retracted.

20.10.2016

When all of the above requirements have been satisfied, the SLI will automatically switch to the rigging tables and derricking is then permitted within the angle range that is below the working range of approx. 15°.

5.3.3

Telescoping with rigged boom extension

Slewing range of 360°

S

Risk of overloading of the main boom!

If you are telescoping the main boom with the rigged boom extension, you may not simultaneously slew the superstructure.

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

Telescoping will only be enabled by the SLI if the main boom is derricked to a certain angle and a maximum permissible load is not exceeded.

The required angle (between 75° and 80°) depends on the rigging mode of the truck crane.

You will find the required main boom angle and the maximum permissible load (weight of the hook block) in the Lifting capacity tables, in the chapter Rigging tables – boom extension.

If the main boom angle is too small for telescoping with the boom extension, the SLI displays an appropriate error message.

Span of 6.30 x 8.70 m

S

Risk of overturning backwards!

Given a span of 6.30 x 8.70 m and a lateral main boom position, telescoping is prohibited. There is a risk of overturning backwards.

Do not override the SLI. If the boom extension is rigged into position on the side, – raise the main boom, – slew the superstructure backwards into the 0° position and switch off the slewing gear, – telescope the main boom to the required length, – switch on the slewing gear and slew the superstructure to the side.

20.10.2016

If the main boom angle is too large for telescoping with the boom extension, the SLI displays an appropriate error message.

5.3.5

G

Procedure if permissible wind speed is exceeded Risk of accidents due to excessively high wind speeds!

If the current wind speed is higher than the maximum permissible wind speed, cease crane operation immediately and set up the corresponding rigging mode.

This prevents the truck crane from overturning due to overloading.

• Prior to and during crane operation, check whether the current wind speed is lower than the maximum permissible wind speed.

• Make sure that you follow the instructions for checking the wind speed;

à Lifting capacity table and GMK 6300L operating manual.

If the maximum permissible wind speed is exceeded No automatic shutdown occurs if the maximum permissible wind speed is exceeded.

• Immediately cease crane operation.

• Bring the truck crane into the rigging mode specified for the current wind speed in the Lifting capacity table.

When operating the auxiliary single-sheave boom top, the maximum speed for the power units is not limited, GMK 6300L operating manual.

à

The raising, lowering, slewing, derricking and telescoping movements are carried out in the same way as when operating with the main boom. This section only contains information that you will need for a rigged or folded up auxiliary single-sheave boom top:

6.3.1

Setting the SLI • In addition, enter the following into the SLI: – the current rigging mode for operation with the main boom and

– the current reeving at the auxiliary single-sheave boom top for the hoist whose hoist rope is switched to the auxiliary single-sheave boom top.

The loads specified in the lifting capacity tables are reduced during operation with the auxiliary single-sheave boom top if: – a hook block is reeved in on the main boom, or – the swing-away lattice is folded to the side on the main boom.

The values which must be deducted from the load capacities depend on the length of the swing-away lattice and the weight of the hook block. You will find a table with the values in the lifting capacity tables in the section Information on working with the swing-away lattice extension. The SLI switches off correspondingly earlier.

G

Derricking, telescoping the main boom Risk of accidents if the SLI is overridden!

Do not override the SLI when lowering the boom into a horizontal position.

If the SLI is overridden, the crane operations will not be monitored and the truck crane will overturn if you leave the permissible working range.

The requirements that must be satisfied before the raising, setting and telescoping of the main boom with rigged auxiliary single-sheave boom top are permitted for a slewing range of 360° are monitored by the SLI; GMK 6300L operating manual – Crane operation.

7.3

Operation with the heavy load lattice extension The raising, lowering, slewing, derricking and telescoping movements are carried out in the same way as when operating with the main boom. This section only contains information that you will need for a rigged or folded heavy load lattice extension.

7.3.1

Setting the SLI • In addition, enter the following into the SLI: – the current rigging mode for operation with the heavy load lattice extension and

– The current reeving on the heavy load lattice extension is entered for the hoisting gear whose hoist rope is reeved on the heavy load lattice extension.

The loads specified in the lifting capacity tables will be reduced during operation with the heavy load lattice extension if: – a hook block is reeved in on the main boom, or – the swing-away lattice is folded to the side on the main boom.

Derricking, telescoping the main boom

Slewing range of 360°

G

Risk of accidents if the SLI is overridden!

Do not override the SLI when lowering the boom into a horizontal position.

If the SLI is overridden, the crane operations will not be monitored and the truck crane will overturn if you leave the permissible working range.

The requirements that must be satisfied before the raising, lowering and telescoping of the main boom with rigged heavy load lattice extension are permitted, for a slewing range of 360° are monitored by the SLI; GMK 6300L operating manual.

à

If the main boom is set to a steep angle and if the heavy load lattice extension is at 8°, the hook block may hit the main boom. When the minimum permitted working radius has been reached, the SLI will prevent the boom being raised further.

Telescoping with span of 6.30 x 8.70 m or 5.00 x 8.70 m

S

Risk of overturning backwards!

Given a span of 6.30 x 8.70 m or 5.00 x 8.70 m and a lateral main boom position, telescoping is prohibited. There is a risk of overturning backwards.

Do not override the SLI. If the heavy load lattice extension is rigged into position on the side, – raise the main boom, – slew the superstructure backwards into the 0° position and switch off the slewing gear, – telescope the main boom to the required length, – switch on the slewing gear and slew the superstructure to the side.

20.10.2016

If the main boom angle is too large for telescoping with the heavy load lattice extension, the SLI displays an appropriate error message.

Procedure if permissible wind speeds are exceeded Risk of accidents due to excessively high wind speeds!

If the current wind speed is higher that the maximum permissible wind speed, stop crane operation immediately and set up an appropriate rigging mode.

This prevents the truck crane from overturning due to overloading.

• Prior to and during crane operation, check whether the actual wind speed is lower than the maximum permissible wind speed.

• Make sure that you follow the instructions for checking the wind speed;

à GMK 6300L operating manual.

If the maximum permitted wind speed is exceeded No automatic shutdown occurs if the maximum permissible wind speed is exceeded.

• Immediately stop crane operations.

Turning loads Two-hook operation is required to turn loads.

Two-hook operation is permissible only with: – Swing-away lattice or – Auxiliary single-sheave boom top or – Heavy load lattice extension.

G H H 8.1

Risk of accidents due to overloading Lifting a load with two hooks is permitted only if the following instructions and illustrations are observed.

If these instructions are disregarded, accidents can occur due to individual parts of the truck crane being overloaded. The SLI then no longer provides protection.

For the position and function of the necessary operating elements; Operating instructions GMK 6300L.

à

In two-hook operation, the loads given in the Lifting capacity table are reduced by the weight of both reeved hook blocks.

Prerequisites The following description requires that: – the main hoist rope is reeved on the main boom; – the auxiliary hoist rope is reeved on the lattice extension, – the lifting limit switches for both hoists are connected, – the reeving on the main boom is the same or greater than the reeving on the lattice extension and

20.10.2016

– the SLI code is set according to the Lifting capacity table for the actual rigging status of the truck crane with the rigged lattice extension.

Turning loads 8.2 Setting the SLI

8.2

Setting the SLI For two-hook operation, on the SLI you must: – enter the current reeving for the main and auxiliary hoist.

The values are stored and opened directly when switching hoists.

– Switch on operation with both hoists in such a way that the digit for the auxiliary hoist lights up on the Hoists display.

Entering the reeving If the symbol (1) is shown without digits on the reeving input, you must switch input mode on:

• Press the button next to symbol (1) once.

Input mode is switched on if symbol (1) is highlighted in green. A digit that displays which hoist the reeving applies to appears next to symbol (1).

Digit I: Main hoist Digit II:

Auxiliary hoist

• Enter the current number of lines (2) of the reeved hoist rope for the displayed hoist ( 8 9 ), e.g. 09, for the main hoist.

• Press the button next to the symbol (1) repeatedly until the digit for the other hoist is displayed (e.g. II for the auxiliary hoist).

• Enter the current number of lines (2) of the reeved hoist rope for the displayed hoist ( 8 9 ), e.g. 02 for the auxiliary hoist.

Now the reeving has been entered for both hoists.

The SLI always takes the reeving entered for the hoist that is displayed at the Hoists indicator lamps into account. For turning loads, the SLI must take the auxiliary hoist and its reeving into account and both hoists must be switched on. To access this SLI setting, proceed as follows:

Turning a load

S H

Carry out the load turning only as it is described in this section.

Risk of accidents due to overloading Keep the acceleration forces as low as possible during two-hook operation.

For this reason, move the load at the lowest possible speed.

As soon as the load is on two hooks, there will be slight differences in the Current load display. However, these deviations are still on the safe side as regards an SLI shutdown.

20.10.2016

In principle, turning loads with the auxiliary single-sheave boom top or heavy load lattice extension is performed as for turning load with the swingaway lattice, shown below.
