Establishing/disconnecting electrical connections –swing-away lattice
GRisk of crushing due to movement of swing-away lattice
Always lock the swing-away lattice or secure it with the guide ropes to prevent it from swinging before you start establishing or disconnecting electrical connections.
This prevents the swing-away lattice from swinging and crushing you.
Depending on the swing-away lattice A - C being used, you must establish/ separate different electrical connections 1 to 5 for sections 1 to 4.

5.4.24 Derricking cylinder positions
SRisk of damage to the swing-away lattice and add-on parts!
Ensure that all necessary connections have been established and separated as specified in the checklist before lowering the swing-away lattice. Do not derrick the swing-away lattice beyond the position shown by the markings. This prevents damage to the connecting points or add-on parts.
The position (A) is reached when the pointer (4)and the marking (3) line up as shown in the figure above.
When rigging into the operating position
Position (A)
The swing-away lattice has been lowered far enough so that the forks (5) can be swung into the hangar elements (6) on the main boom.
When rigging in the transport position
The swing-away lattice is lowered far enough out so that the connecting point at section1 (1) can be swung into the Rear connection(2).
To derrick the swing-away lattice with the hand-held control unit; à p.5-113.
5.4.25 Derricking the swing-away lattice for rigging work – hand-held control
Derricking the swing-away lattice in operation; à p.5-125.
Before derricking the lattice extension, enter an RCL code for working with the lattice extension so that derricking will be enabled; à Setting the RCL, p.5-123.
The button (1) is only active when the swing-away lattice is electrically connected.
• Press the button (1) – the engine starts.
Pre-select the lattice extension derricking gear
• Press the button (1).
–The lamp in the button will illuminate.
Derricking the swing-away lattice
1 Raise swing-away lattice
2 Lower swing-away lattice
• Press the button combination for the desired movement: The further you press the button (1) or (2) in, the faster the movement.
The pre-selected movement will be executed until you let go of the respective button or until the respective end position has been reached.
5.4.26
Derricking the swing-away lattice – Section2 control unit
The control unit (1) provides an additional method for raising/lowering the swing-away lattice.
The control unit moves when derricking, which means that derricking should preferably be operated via the hand-held control or from the crane cab.
The control unit should only be used for relieving the load on the connecting points between the swing-away lattice and main boom, when the swing-away lattice is set down with the skids (2) on the ground or for carefully setting the skids onto the ground after the swingaway lattice has been derricked almost to the ground using a different control unit.
GRisk of crushing due to swing-away lattice movements! Take care to ensure that your feet, fingers or hands are not crushed when raising/lowering the swing-away lattice.
GRisk of accidents due to swing-away lattice movements!
Perform derricking standing next to the derricking area with both feet on the ground and derrick the swing-away lattice only within a small area above the ground that you can easily reach. Do not use a ladder. This prevents the swing-away lattice from knocking you off the ladder and also prevents you from falling of the ladder as you follow the control unit during derricking.
Prerequisite
–The electrical connections between the swing-away lattice and the main boom have been established; à p.5-90.
Derricking the swing-away lattice
Raising: • Press the buttons (1) and (3) – the swing-away lattice lowers.
Lowering: • Press the buttons (2) and (3) – the swing-away lattice is raises.
The swing-away lattice is raised or lowered until you release the button or an end position is reached.
5.4.27 Setting the angle – with an auxiliary crane
This section is only valid for the inclinable swing-away lattice.
GRisk of accidents due to swing-away lattice folding down
Always secure the swing-away lattice with an auxiliary crane or by setting it down on the ground before knocking out the pins for angling. In this way, you prevent the swing-away lattice from suddenly unfolding downwards and causing personal injury.
• Lift the swing-away lattice using an auxiliary crane.
• Remove the pin (1) from the bore.
• Insert the pin for the desired angle into the corresponding bore (1).
• Secure the pin.
• Lower the swing-away lattice down or lift itup.
• Remove the lifting gear.
If the swing-away lattice now touches the ground at the set angle, then the angle will set itself when the main boom is raised.
5.4.28 Setting the angle – without the auxiliary crane
If an auxiliary crane is not available, the swing-away lattice must be set down before it is angled.
SRisk of damage to the hoist rope!
Unreeve the hook block and set down the hoist rope beside the swing-away lattice before you angle the swing-away lattice.
In this way you prevent the hoist rope from being damaged when the head of the swing-away lattice is set down on the ground for angling.
Entering the RCL code
For angling without an auxiliary crane, you must enter the RCL code for working with a mounted lattice extension.
Comply with the information in the section Rigging tables - lattice extension in the lifting capacity tables. Among other information, this specifies the possible telescoping modes and the maximum lifting capacity.
GRisk of overturning with impermissible rigging mode
Always enter the RCL rigging code for the current rigging mode of the truck crane, and only slew the superstructure into the operating position permitted by the RCL rigging code set according to the lifting capacity table. This prevents the truck crane from overturning when the main boom is telescoped out.
GRisk of overturning with raised hook block (hook tackle)!
The telescoping range which is enabled for the RCL code set is only permitted for telescoping without a load and without hook block/hook tackle. When the main boom is fully extended, load measurement is not possible and the RCL monitoring depends on the working radius only.
For this reason, you must unreeve the hook block. This prevents the truck crane from overturning when the main boom is telescoped out.
Setting the angle This section assumes that the swing-away lattice has been locked in front of the main boom and the unreeved hoist rope has been set down beside the swing-away lattice.
GRisk of accidents if this procedure is not followed. For the procedure described here, the swing-away lattice must be set down on the ground. If the swing-away lattice is to be set down on some other structure for inclination, please bear in mind that the swing-away lattice will slide towards the truck crane when raised, until the angle of inclination is reached.
While doing that, the swing-away lattice could slip off an unsuitable structure, fold down and cause personal injury.
GRisk of accidents when RCL is overridden. Never override the RCL if the crane movements are switched off. In this way you prevent the superstructure from being slewed out of the permissible working range and the truck crane tipping over as a result.
• For inclining, enter the correct RCL code for the current rigging mode of the truck crane; à lifting capacity tables.
• Slew the superstructure into an operating position permitted by the lifting capacity table for the RCL rigging code set.
HThe following diagrams each show an example of a crane.
• Extend the main boom as far as is permitted for the RCL rigging code set, or as far as possible given the space available.
• Lower the main boom until the swing-away lattice head touches the ground.
• If the ground cannot be reached, you can incline the truck crane further; à p.5-121.
HIn the steps which follow, the swing-away lattice head is pulled or pushed over the ground. Lay boards, for example, under the skids on the head so that it is not pushed into the ground or damaged.
• If necessary, relieve the load on the pin (1) by raising slightly.
• Move the pin (1) into the position for the angle required, e.g. for angle of 15°; à Setting the angle – with an auxiliary crane, p.5-115.
• Raise the main boom slowly. When doing so, the head of the swing-away lattice will be pulled across the ground.
• Raise the main boom until the swing-away lattice head is no longer touching the ground.
The swing-away lattice will then be inclined by the angle set, e.g. 15°.
If you inclined the truck crane using the outriggers in order to set the angle, align it to the horizontal again.
• Fully retract the main boom. While doing so, the swing-away lattice must not touch the ground (raise now and then if necessary).
• Set the head of the swing-away lattice down on the ground.
• Slowly lower the main boom into a horizontal position.
When doing so, the head of the swing-away lattice will be pushed across the ground. The swing-away lattice is now in the right position for attaching the hoist rope.
Setting a 0° angle
GRisk of overturning when truck crane is standing at an angle! After setting the angle, always check whether the truck crane is aligned to the horizontal.
In this way you prevent the actual working range differing from the permitted working range, leading to the truck crane tipping over.
The section assumes that no load has been raised and that the hook block has been unreeved.
• Set the head of the swing-away lattice down on the ground.
HIn the steps which follow, the swing-away lattice head is pulled or pushed over the ground. Lay boards, for example, under the skids on the head so that it is not pushed into the ground or damaged.
• Slowly lower the main boom into a horizontal position. When doing so, the head of the lattice extension will be pushed across the ground.
• Remove the hoist rope (1) and set it down beside the swing-away lattice.
• Slowly lower the main boom until the swing-away lattice head is no longer touching the ground.
• Enter the RCL code for the current rigging mode.
• Extend the main boom as far as is permitted for the RCL rigging code set, or as far as possible given the space available.
• Lower the main boom until the swing-away lattice head touches the ground.
• If the ground cannot be reached, you can incline the truck crane further; à p.5-121.
• Slowly lower the main boom until the 0° angle is reached. When doing so, the head of the swing-away lattice will be pushed across the ground.
• Put the pin (1) of the angle piece into the position for a 0° angle; à Setting the angle –with an auxiliary crane, p.5-115.
• Derrick the main boom into the horizontal position and retract it completely.
The swing-away lattice is now in the right position to continue unrigging.
HIf you inclined the truck crane using the outriggers, align it to the horizontal now so that the swing-away lattice sections can be folded more easily.
Inclining the truck crane
For inclining, you must set the swing-away lattice down on the ground by extending and lowering the main boom.
Depending on the space available, the condition of the terrain or a limitation on the telescoping due to the current rigging mode, it may be that the swing-away lattice cannot be set down on the ground by telescoping and lowering the main boom.
In this case, you can use the outriggers to incline the truck crane.
GRisk of accidents if the wheels touch the ground! Make sure that the wheels do not touch the ground when the truck crane has been inclined. In this way you prevent a reduction in the stability of the truck crane, which could lead to it tipping over when setting the angle.
• Extend the supporting cylinders on the counterweight side.
• Retract the supporting cylinders on the main boom side, if necessary. Be sure that the wheels do not touch the ground when doing this.

5.5 Operation with swing-away lattice
5.5 Operation with swing-away lattice
The raising, lowering, slewing, derricking and telescoping movements of the main boom are carried out in the same way as when operating with the main boom. This section only contains information that you will additionally need for a rigged or installed swing-away lattice.
5.5.1 Setting the RCL
Input
• Enter the current rigging mode for operation with a rigged swing-away lattice into the RCL. Either via the corresponding RCL code in accordance with the lifting capacity table or via the individual components.
If you enter the current rigging mode via the individual components then you must also additionally enter the length of the swing-away lattice.
• Enter the current reeving on the swing-away lattice for the hoisting gear whose hoist rope is reeved on the swing-away lattice into the RCL.
HThe lifting capacity for the RCL code is enabled once the telescopic sections are locked.
Shutdown
Operation with the swing-away lattice is monitored by the RCL.
When operating with the swing-away lattice, RCL shutdowns may occur for the same reasons as when operating with the main boom; à GMK5150 / GMK5150L Operating Instructions
In certain rigging modes, the RCL shuts down when lifting loads that are lighter than the maximum load bearing capacity specified in the lifting capacity table.
–During operation with the swing-away lattice
If a hook block (3) is reeved at the main boom, then the displayed current load (1) is influenced by
–The weight of the lifted load (2) and
–The weight of the hook block (3).
Swing-away lattice
5.5 Operation with swing-away lattice
–During main boom operation à Derricking the swing-away lattice in operation, p.5-125.
5.5.2 Derricking the main boom
Slewing range of360°
GRisk of accidents if the RCL is overridden!
Do not override the RCL when lowering the boom into horizontal position. If the RCL is overridden, the crane operation will not be monitored and the truck crane will overturn if it moves outside of the permissible working range.
The prerequisites for permitting raising and lowering of the main boom with a rigged swing-away lattice over a slewing range of 360° are monitored by the RCL. Further information on the permissible angle ranges and lifting capacities is provided in the lifting capacity table; à Rigging tables - lattice extension.
5.5.3 Telescoping with rigged swing-away lattice
Slewing range of360°
SRisk of overloading 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 from being overloaded by additional lateral forces and increased vibration.
The telescoping of the main boom with a rigged swing-away lattice (in the operating position) is monitored by the RCL.
Telescoping is only released at specific main boom and lattice extension angles when a maximum permissible load is not exceeded. Further information on the permissible angles and the maximum permissible load is provided in the lifting capacity tables. This also provides information on the telescoping paths for rigging the swing-away lattice; à Rigging tables - lattice extension

5.5 Operation with swing-away lattice
5.5.4 Derricking the swing-away lattice in operation
Switching on the derricking gear
After the ignition is switched on, all of the power units will be switched off and the lamps in the corresponding buttons will light up only dimly.
• Press the button (1) once.
–The lamp in button (1) lights up brightly.
–Symbol (2) is green when the derricking gear is switched on.
If the control lever is assigned more than one function, all other power units which are assigned the same control lever movement are switched off.
Raising and lowering
You can adjust the sensitivity of the control levers to the operating conditions; à GMK5150 / GMK5150L Operating Instructions
GRisk of accidents due to unexpected crane movement!
If assigned more than one function, check that the lattice extension derricking gear control lever function is switched on before you move the control lever for derricking the swing-away lattice. This prevents accidents due to unexpected crane movements.
Lowering: Push the control lever to the right - the swing-away lattice will be lowered.
Raising: Push the control lever to the left - the swing-away lattice will be raised.
Other derricking settings are performed in the same manner, as described in the GMK5150 / GMK5150L Operating Instructions.

5.5 Operation with swing-away lattice
When derricking the swing-away lattice the RCL switches automatically to the values for fixed angle and intermediate angle stated in the lifting capacity table if permissible for the load currently being lifted.
If this switchover is not permitted for the load currently raised, derricking will be switched off and a corresponding error message will be generated.
Switching off the derricking gear
• Press the button (1) once.
–The lamp in the button (1) lights up dimly.
–Symbol (2) is red when the derricking gear is switched off.
All power units are switched off and the lamps in the corresponding buttons light up only dimly after turning off the ignition.
5.5.5 Procedure if permissible wind speed is exceeded
GRisk 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 will prevent the truck crane from overturning due to overload.
• 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 GMK5150 / GMK5150L Operating Instructions.
If the maximum permitted wind speed is exceeded: An automatic shutdown does not occur if the maximum permissible wind speed is exceeded.
• Immediately cease crane operation.
• Put the truck crane into the rigging mode specified for the current wind speed in the lifting capacity table.

5.5 Operation with swing-away lattice
5.5.6 Information about the main boom operation when the swingaway lattice is folded/rigged
Folded
During main boom operation with a folded swing-away lattice, the loads specified in the lifting capacity table are reduced and displayed on the maximum load RCL display.
Rigged
HThe lifting capacity tables contain operations planning information specifying the values that must be subtracted from the specified maximum load bearing capacities for certain rigging modes; à Remarks on working with the swing-away lattice.
Main boom operation with rigged swing-away lattice combinations A and B (in the operating position) is permitted.
You must enter an RCL code for the main boom without a swing-away lattice in order to operate in this mode. This operating mode is only permissible under certain specific rigging modes. More information on the permissible rigging modes and the swing-away lattice lengths is provided in the lifting capacity tables; à Remarks on working with the swing-away lattice.
The lifting capacities specified in the lifting capacity table are reduced for main boom operation with rigged swing-away lattice. The lifting capacity tables contain operations planning information specifying the values that must be subtracted from the specified maximum load bearing capacities for certain rigging modes; à Remarks on working with the swing-away lattice
The RCL display does not display the reduced values correctly. This means that the displayed value can deviate from the value that was previously calculated during the operations planning.
If this is the case, the RCL is not faulty. Do not override the RCL. Even if the displayed value is higher than the calculated value.
GRisk of accidents if the RCL is overridden! Do not under any circumstances override the RCL. If the RCL is overridden, the crane operation will not be monitored and the truck crane will overturn if it moves outside of the permissible working range.
