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

• Lower the lattice extension with the retaining mandrel out of the holder on the main boom.

• Swing the lattice extension until it is no longer above the run-up rail.

• Carefully lower the lattice extension from the control unit on the foot of the 12.5 m (41 ft) section until it starts to swing out.

If a helper is holding the guide rope, he can now swing the lattice extension in front of the main boom head.

If you are alone and have attached the guide rope to the crane when securing, the lattice extension now swings only until the guide rope is tight. You can now swing the lattice extension with the guide rope in front of the main boom head.

Swinging the 9 m (30 ft) section in front of the 12.5m (41ft) section

The swinging procedure during rigging is described below. Proceed in the opposite order for unrigging.

Before you swing the 9 m (30 ft) section in front of the 12.5 m (41 ft) section to rig the 22 m (72 ft) two-stage swing-away lattice extension, the 12.5 m (41ft) section must be locked in front of the main boom head; à p.3-53.

• Disconnect the connection between the 9 m (30 ft) section and the 12.5 m (41 ft) section; à Connections in the middle area, p.3-46.

• Swing the 9 m (30 ft) section on the guide rope in front of the head of the 12.5 m (41 ft) section.

• Proceed in the opposite order for unrigging.

3.6.9 Run-up rail

There is a foldable angled plane in the run-up rail. The angled plane can be folded into both the Rigging and Unrigging positions.

Rigging position

• Unscrew the screw (1) until the angled plane (2) is tilted slightly downwards.

Now the angled plane is in the Rigging position.

Unrigging position

• Screw in the screw (1) until the angled plane (2) is tilted upwards.

Now the angled plane is in the Unrigging position.

3.6.10 Swinging the lattice extension onto the main boom head

This section describes how the lattice extension is swung – onto the main boom head for rigging and – onto the main boom basic section for unrigging.

The lattice extension must be swung out of the transport position onto the main boom head so that the swinging connection can be made between the 12.5 m (41 ft) section and the main boom head.

Requirements –The lattice extension is in transport position when the lattice extension is folded at the side; à Transport condition with lattice extension folded at the side, p.3-37.

–The required connections between the lattice extension sections are disconnected under each other or between the lattice extension sections and the main boom.

When swung, the lattice extension rolls on the run-up rail, turns around the retaining mandrel (3) and becomes attached at the front at the stop (1). The stop is set at the factory so that the bearing points (2) now align.

If the bearing points do not align, you can adjust the stop:

• Swing the lattice extension until the bearing points (2) align and make the swinging connection on the right side of the main boom head; à p.3-48.

• Unscrew or screw in the screw ( 1) until there is about a 2 mm (0,08 inch) gap between the screw head and the strut (3).

• When rigging pull the lattice extension at the back away from the basic section until it is at the front at the stop (1); à Connections on main boom head, p.3-48.

• When unrigging push the lattice extension along the stop rail until it stops at the basic section.

3.6.11 Electrical connection on the lattice extension

The SLI, lifting limit switch, lowering limit switch and the control system for derricking the lattice extension are connected via the electrical connection on the lattice extension.

13 m (43 ft) swingaway lattice extension

For the 13 m (43 ft) swing-away lattice extension the electrical connection is made or disconnected on the right side of the main boom head.

Establishing electrical connection

• Remove the short-circuit plug (3) from the socket (4) on the main boom.

• Remove the plug (2) from the dummy socket (1) and insert it in the socket (4) on the main boom head.

• Insert the plug (3) in the dummy socket on the 9 m (30 ft) section.

3.6.12 Establishing/disconnecting the hydraulic connection

The hydraulic supply is required for derricking the lattice extension and consists of:

–the hydraulic connection of the hose drum on the left side of the main boom; à p.3-40, –and the hydraulic connection on the right side of the main boom head which is described in this section.

HThe connections are made via quick couplings. Half couplings which belong together are colour coded. Use the delivered levering tool to make the hydraulic connections; à Connecting quick couplings with levering tool, p.4-17.

Establishing hydraulic connection

• Remove the hose pipes (3) from the holders (1) on the 12.5 m (41 ft) section.

• Connect the hose pipes to the quick couplings (2) on the main boom head (observe colour code).

Disconnecting hydraulic connection

• Remove the hose pipes (3) from the quick couplings (2) on the main boom head.

• Squeeze the hose pipes into the holders (1) on the 12.5 m (41 ft) section.

3.6.13 Folding out/in the deflection sheaves on the 12.5m (41ft) 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.

Folding rear deflection sheave

Folding out deflection sheave

• Hold the deflection sheave by the handle (3) and remove the pin (2) from the bore (4).

• Fold the deflection sheave up and secure it with the pin in the bore (1).

• Secure the pin with a retaining pin.

Folding up deflection sheave

• Hold the deflection sheave by the handle (3) and remove the pin (2) from the bore (1).

• Fold the deflection sheave down and secure it with the pin in the bore (4).

• Secure the pin with a retaining pin.

3.6.15

Overriding connection on main boom

Lifting limit switch on the lattice extension

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

HThe same lifting limit switch is used for lattice extension and main boom.

For operation with the lattice extension you must remove the lifting limit switch on the main boom and override the connection.

• Insert the short-circuit plug (1) in the socket for the connection of the lifting limit switch. The connection is now overridden.

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

On the 13 m (43 ft) swing-away lattice extension

• Place the lifting limit switch (4) in the holder (5) and secure it with a retaining pin.

• Remove the short-circuit plug (2) from the socket (1).

• Connect the lifting limit switch on the socket (1) by guiding the cable upwards through the opening in the sheet behind the strut (3).

• When rigging you must insert the short-circuit plug (2) back in the socket (1).

On the 22 m (72 ft) two-stage swingaway lattice extension

HFor operation with the 22 m (72 ft) two-stage swing-away lattice extension the connection for the lifting limit switch on the 12.5 m (41 ft) section must be overridden with a short-circuit plug.

• Place the lifting limit switch (2) on the shackle (1) and secure it with a retaining pin.

• Connect the lifting limit switch on the socket (3).

When unrigging close the socket (3) with the protective cap.

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

3.6.16 Anemometer on the lattice extension

HThe same anemometer is used for lattice extension and main boom.

On the 13 m (43 ft) swing-away lattice extension

• Secure the anemometer (3) to the holder (2) on the head of the 12.5 m (41 ft) section and secure it with a retaining pin.

• Insert the plug (1) of the connecting cable in the distribution box on the head of the 12.5m (41 ft) section.

On the 22 m (72 ft) two-stage swingaway lattice extension

• Attach the anemometer (1) to the holder (2) on the head of the 9 m (30 ft) section and secure it with a retaining pin.

• Insert the plug (3) of the connecting cable in the distribution box on the head of the 9m (30 ft) section.

HYou must remove the anemometer before unrigging the lattice extension.

3.6.17 Derricking lattice extension

Before derricking the lattice extension set an SLI rigging code or a SLI code for work with the lattice extension.

When rigging To derrick the lattice extension when rigging there are two control units each with two pushbuttons on the 12.5 m (41 ft) section.

• To raise press the top pushbutton Raise lattice extension (1).

• To lower press the bottom pushbutton Lower lattice extension (2).

During operation z• The indicator lamp Right control lever in derrick lattice extension function lights up and you can derrick the lattice extension with the right control lever.

During operation the lattice extension is derricked from the crane cab.

• Press the Preselection of derricking control lever function / telescoping / derrick lattice extension rocker switch down.

• To raise press the right control lever to the left

• To lower press the right control lever to the right

3.6.18 Transportation on a separate vehicle

GAttach the lattice extension only at the prescribed slinging points and always use lifting gear with sufficient load bearing capacity. This prevents the lattice extension falling and injuring people while loading; à Slinging points, p.3-9.

Place the lattice extension for transportation on the supports (1) on the head and foot of the 12.5 m (41 ft) section.

• Always secure the lattice extension on the separate vehicle with belts as well to prevent slipping and overturning.

SRisk of damaging the lattice extension! Always secure the lattice extension by tying it down with suitable belts when it is transported on a separate vehicle. This prevents the two-stage swing-away lattice extension tipping and becoming damaged during transportation.

Two-stage swing-away lattice extension

3.7 Raising the setting down the main boom with rigged lattice extension

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

GRisk 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.

HTo 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:

–The SLI code for the actual rigging mode is set on the SLI with the 13m (43 ft) swing-away lattice extension or 22 m (72 ft) two-stage swing-away lattice extension; à Operating instructions GMK5200/6220-L , part 2, chapter Crane operation, Section Operating the safe load indicator – Setting rigging mode.

–The current reeving of the hoist rope on the lattice extension is entered. –Apart from the hook block there is no load on the lattice extension.

• Derrick in the main boom to raise.

• Derrick out the main boom to set down.

3.7 Raising the setting down the main boom with rigged lattice extension

3.7.1 Telescoping with rigged lattice extension

SThe 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.

HThe 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 depends on the length of the lattice extension; à Rigging programs in the lifting 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.

• Put down the load.

• Raise the main boom to an angle necessary according to the rigging program (à Rigging programs in the lifting capacity table).

• 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

HThe information in this section also applies to operation with the boom extension.

HIf 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

Two-stage swing-away lattice extension 3.7 Raising the setting down the main boom with rigged lattice extension

GRisk 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.

HThe 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. 7580°, depending on the length of the lattice extension (exact value à Rigging programs in the Lifting capacity table ).

SLI shutdown When working with the 13 m (43 ft) swing-away lattice extension or the 22m (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 reasons as with main boom operation; à Operating instructions GMK5200/ 6220-L, part 2, chapter Crane operation, Section Operating the safe load indicator – During crane work.

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 instructions in the Effect of wind on crane operation, à Operating instructions

GMK5200/6220-L, part 2, chapter Crane work with the main boom – External influences during crane operation

Procedure when exceeding the permissible wind speed during operation with the lattice extension or boom extension

Wind speed less than 20 m (66 ft)/s

• Put down the load.

• Turn the superstructure in such a way that the main boom provides the wind with as little working surface as possible

Wind speed greater than 20 m (66 ft)/s

• Put down the load.

• Completely retract the main boom.

• Set the lattice extension down.

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.

GRisk 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!

GRisk of accidents due to overloading!

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

HYou can find the position and function of the required operating instruments in the supplied GMK 5200/6220-L Operating Instructions

3.8.1 Requirements

The following description requires that:

–the main hoist rope is reeved on the main boom and

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

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

GRisk 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.

Two-stage swing-away lattice extension

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

3.8.2 Setting SLI

For two-hook operation both hoists must be activated on the SLI.

HIt 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: Cü

• Switch both hoists off.

To do this press down both rocker switches Auxiliary hoist shutdown and Main hoist shutdown ü• Switch on the main hoist.

To do this push up the rocker switch Main hoist shutdown.

Lamp I for the main hoist lights up in the Hoists position lamps.

• In the display Reeving, enter the quantity of reeved rope on the main hoist rope of the main boom.

Now the reeving for the main hoist is stored and you can switch to the auxiliary hoist. Cü

• Switch off both hoists.

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

C• Switch on the auxiliary hoist.

To do this push up the rocker switch Auxiliary hoist shutdown.

On the indicator lamps Hoists lamp II is flashing for the auxiliary hoist.

• In the display Reeving, enter the quantity of reeved rope on the auxiliary hoist rope of the lattice extension.

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

Two-stage swing-away lattice extension

3.8 Turning loads with the two-stage swing-away lattice extension ü• 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.

• Set the SLI code for operation with the telescopic swing-away lattice extension which is valid for the current rigging mode of the truck crane.

The SLI is thus set for two-hook operation; it now takes into consideration the reeving for the auxiliary hoist and the lifting capacity tables for the lattice extension.

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

Two-stage swing-away lattice extension

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

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

SDanger 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.

HIf 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.

HIf 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.

• Lift the load fully with the lattice extension.

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

• Now lift the load with the hook block on the main boom until both slinging points are at the same height.

Two-stage swing-away lattice extension

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

• Slacken the hoist rope on the lattice extension until the load is only hanging from the hook block on the main boom.

Turning the load is thus completed.

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.

GRisk 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.

GRisk of overturning!

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

3.9.1 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).

SRisk 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 required air pressure; à GMK 5200/6220-L operating instructions , Part 2, Chapter Technical information, Section Carrier – Tyres

Do not reduce the tyre pressure!

3.9 Driving with rigged crane and two-stage swing-away lattice extension installed

3.9.2 Rigging mode and axle loads GMK 5200

The vehicle may only be moved under certain circumstances. The main boom and the lattice extension must be moved to a specific position, depending on the installed counterweight. The tables on the following pages provide an overview of the possible settings.

SDanger of damage to the axle lines!

Always move the main boom and the lattice extension to the prescribed position before you move the rigged truck crane. The permitted loads on the axle lines are exceeded if the boom is in a position which deviates from the prescribed position.

• Set the appropriate SLI code for the rigging mode on the safe load indicator. The SLI codes are found in the Lifting capacity table.

• Move the boom into the prescribed position. The prescribed boom position can be found in the following tables.

SRisk of accidents if SLI is overridden!

Always set the SLI rigging code corresponding to the current rigging mode when you derrick the main boom into the prescribed position. Do not override the SLI; the prescribed positions in the following tables all lie within the areas which are permitted according to the Lifting capacity tables. The truck crane safe load indicator does not function when the SLI is overridden!

0° to the rear for the superstructure position

• Set the appropriate SLI code for the current rigging mode on the safe load indicator. The SLI code can be found in the Lifting capacity table.

• Slew the superstructure into the position required (0° to the rear or 180° to the front).

• Lock the superstructure. The Counterweight locked indicator lamp must be lit.

• Derrick the main boom to 82°.

• Fully retract the main boom.

• Set a lattice inclination of 5°.

The tables on the following pages allocate a Telescoping rigging code and a Derricking rigging code for each counterweight combination to the different lattice extensions.

• Enter the Telescoping rigging code for the lattice extension currently rigged (e.g. 790 on the SLI for rigged 13 m lattice extensions and counterweight combinations 44.0 t). H

If SLI shutdown then occurs:

–The lattice inclinations does not correspond to the specified angle, or –The current load exceed the maximum vpermitted value (e.g. a too large hook block has been reeved).

The tables on the following pages allocate a Telescoping rigging code and a Derricking rigging code for each counterweight combination to the different lattice extensions.

GDanger 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.

Driving

b• Switch on separate steering by releasing the Separate steering rocker switch and pressing it down.

SDamage may occur to steering linkage! Before driving with the rigged crane always switch on separate steering and steer the truck crane only when the vehicle is moving. If separate steering is switched off or if you steer with the vehicle stationary the steering linkage may become damaged.

SRisk of tyre damage!

Check the pressure in the tyres before the rigged truck crane is moved! The truck crane may be moved only if tyre pressures are at the prescribed levels; à GMK 5200/6220-L operating instructions, Part 2, Chapter Technical information, Section Carrier – Tyres. Do not reduce the tyre pressure!

HThe wind speed must be checked before the rigged truck crane is moved! The same maximum permissible wind speeds apply as when working with the crane; à GMK 5200/6220-L operating instructions, Part 2, Chapter Crane operation, Section Crane work with main boom – External influences during crane operation – Effect of wind on crane operation.

• To move the truck crane, switch the transfer case to off-road gear; à GMK 5200/6220-L operating instructions, Off-road gear

• Switch to Gear 1; à GMK 5200/6220-L operating instructions, Automatic gearbox – Operation .

• Drive at only a very low speed!

• The turning radius should be as large as possible when turning corners!

• Steer the truck crane only when it is moving and avoid sudden steering movements!

Extending the outriggers
