2 Basic safety instructions 2.2 Safety instructions for working with a lattice extension

2.2

Safety instructions for working with a lattice extension This chapter contains additional safety instructions only for safe use of the lattice extensions described in this operating manual.

Working at heights

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

The lattice extensions are provided with clamps for positioning a ladder. Place the ladder between the clamps so that it cannot slip off.

If despite using such equipment the risk of falling cannot be minimised you must protect yourself and any assisting personnel by using fall arrest systems.

The points to which the fall arrest system can be attached on the truck crane are indicated by the symbol shown here.

Slinging

Attach parts only at the designated slinging points. If no slinging points are provided, then observe the centre of gravity specifications.

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

Locks

Always secure the pins at the connection points and also at the holders using the appropriate locks. This prevents unsecured pins from coming loose, falling out and causing injuries.

Rigging mode

For crane operation with the lattice extension folded, comply with the rigging mode. That prevents damage to the main boom or lattice extension, and prevents the lattice extension from falling during crane operation.

For on-road driving with the lattice extension, comply with the rigging mode.

This prevents the permissible vehicle width or height from being exceeded.

Lifting loads simultaneously with two cranes is particularly dangerous. Carry out this type of work with special caution.

Risk of accidents when using an incorrect swing-away lattice!

Install only the swing-away lattice that belongs to the truck crane. Other swing-away lattices must not be installed.

If the swing-away lattice is to be used on several truck cranes, the swing-away lattice must be adapted to the truck crane and marked with the corresponding serial numbers. Only have this modification carried out by Manitowoc Crane Care or an authorised GROVE dealer.

5.2.2

Transport conditions – Instructions for checking A correctly established transport condition is important for several operations.

– For safe rigging – For safe transport – For safe main boom operation

• Make sure that the corresponding transport condition is always established for the current operation.

• Always check the transport condition if you are requested to do so according to a checklist.

• Always check the transport condition before driving the truck crane with folded swing-away lattice sections.

• Always check the transport condition before using the main boom with folded swing-away lattice sections.

• Always check the transport condition before transporting the removed swing-away lattice with a separate vehicle.

• Observe the safety instructions in this section.

G G

Risk of accidents during installing/removing and when rigging!

If a checklist refers to the inspection of the transport condition, it is assumed that all connections have been established as specified for the corresponding transport condition.

Make sure that the corresponding transport condition has been established before dealing with the next checklist item.

This prevents the swing-away lattice from falling down or swinging and hitting or crushing you.

Risk of accidents due to falling parts!

Always make sure that the corresponding transport condition has been established before driving the truck crane with a folded swing-away lattice or main boom operation.

That prevents the sections of the swing-away lattice from falling down and injuring or even killing persons.

Risk of damage to the swing-away lattice and main boom!

Always make sure that the corresponding transport condition has been established before driving the truck crane with a folded swing-away lattice or main boom operation.

That prevents the sections of the swing-away lattice from hitting each other or the main boom.

Risk of damage to the swing-away lattice!

Always secure the swing-away lattice by tying it down with suitable belts when it is transported on a separate vehicle. That prevents the swing-away lattice from tipping over and becoming damaged during transport.

24.01.2020

G S S

Risk of injury!

Before transport, ensure that all cables, hoses and pins are securely fastened in the clamps and cannot come loose while driving. Additionally fasten the cables and hoses if necessary.

That prevents the sections from falling down while driving and injuring or even killing persons.

Securing the swing-away lattice with the guide rope Risk of accidents due to sections swinging of their own accord!

Always fasten a guide rope to the sections being swung before you disconnect the required connections.

An extra person must keep the guide rope tightly tensioned or you must fasten the guide rope so that the sections cannot swing unintentionally when the necessary connections are unlocked or separated.

Fastening a guide rope to section 2

• Fasten the guide rope to the swing-away lattice A or B, for example to the rope attachment point (1).

Fastening a guide rope to section 1

• Fasten the guide rope (1) behind the head of

Folding out / folding in the deflection sheave Risk of accidents by exceeding the total permissible height!

Fold in the deflection sheave before driving with folded swing-away lattice. When the deflection sheave is folded out, the overall height specified for the on-road level is exceeded.

Risk of crushing!

Always hold the deflection sheaves on section 2 firmly by the handle when removing the pin.

Your fingers can be crushed if you hold a sheave by the side panel.

Folding out

• (A) – Hold the deflection sheave tightly by the handle (1) and pull out the pin (2).

• (B) – Fold the deflection sheave (3) up and fasten it in this position with the pin (2).

• Secure the pin (2) using the retaining pin.

Risk of crushing due to swing-away lattice swinging around!

Always secure the swing-away lattice against swinging around.

This prevents you from being caught or crushed by sections.

Risk of damage to the hoses!

Lay the hoses in such a way that they are suspended freely under the main boom head. That prevents the hoses from being crushed or torn off when swinging the swing-away lattice.

Risk of damage!

Always disconnect the hydraulic connection when the swing-away lattice is in the transport position.

That prevents the hoses from being torn off when telescoping and it prevents the position of the derricking cylinder from changing independently and the connecting points in range 1 from being tensioned.

The figures in this section show the operation in the transport position.

The operation is carried out in the same way in the working position.

With the control unit on section 2 The control unit (1) 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 when the swingaway lattice is set down with the skids (2) on the ground or for carefully setting the skids onto the ground after the swing-away lattice has been derricked almost to the ground using a different control unit.

G

Risk of accidents and risk of crushing due to derricking swing-away lattice!

Do not use a ladder.

That 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.

Stand outside 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. Take care to ensure that your feet, fingers or hands are not crushed.

Risk of accidents due to swing-away lattice folding down!

Always secure the swing-away lattice with an auxiliary crane, or set it down on the ground, before removing the angling pin from the bore.

That prevents the swing-away lattice from unfolding downwards in an uncontrolled manner and causing personal injury.

• Raise the swing-away lattice with an auxiliary crane and remove the pin (1).

• Insert the pin for the desired angle.

– For an angle of 0° – in the bore (2).

– For an angle of 20° – in the bore (3).

• Secure the pin.

• Lower the swing-away lattice.

If the swing-away lattice now touches the ground, then the angle will set itself when the main boom is raised.

5.12.2

Without auxiliary crane If an auxiliary crane is not available, the swing-away lattice must be set down before it is angled.

S Entering the RCL code

Risk of damage to the hoist rope!

Unreeve the hook block and set down the hoist rope next to the swing-away lattice before you angle the swing-away lattice.

In this way you prevent the hoist rope from being damaged when the swing-away lattice is set down on the ground for setting the angle.

For setting the angle without an auxiliary crane, you must enter the RCL code for working with a mounted swing-away lattice.

When inclining without an auxiliary crane, comply with the information in the section Rigging tables – lattice extension in the lifting capacity tables. Among other information, it specifies the possible telescoping modes and the maximum lifting capacity.

Risk of overturning with raised hook block (hook tackle)!

The telescoping range which is enabled for the set RCL code 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 RCL monitoring depends on the working radius only.

For this reason, you must always unreeve the hook block. That prevents the truck crane from overturning when the main boom is telescoped out.

24.01.2020

G G

Risk of overturning with impermissible rigging mode!

Always enter the RCL code for the current rigging mode of the truck crane, and only slew the superstructure into the working position permitted by the RCL code set according to the lifting capacity table.

That prevents the truck crane from overturning when the main boom is telescoped out.

Setting the angle

G G

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 next to the swingaway lattice.

Risk 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 setting the angle, please bear in mind that the swing-away lattice will slide towards the truck crane when raised, until the angle is reached.

While doing that, the swing-away lattice could slip off an unsuitable structure, fold down and cause personal injury.

Risk of accidents when RCL is overridden!

Never override the RCL if the crane movements are switched off. That prevents the superstructure from being slewed out of the permissible working range and the truck crane from tipping over as a result.

• Enter the correct RCL code for the current rigging mode of the truck crane;

à Lifting capacity table.

• Slew the superstructure into a working position permitted by the lifting capacity table for the set RCL code.

H

The following diagrams each show an example of a crane with swing-away lattice.

• Extend the main boom as far as is permitted for the set RCL 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;

In the steps that 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. 40°;

• Raise the main boom slowly.

When doing so, the head of the swing-away lattice is pulled across the ground.

• Raise the main boom until the swing-away lattice head is no longer touching the ground.

The swing-away lattice is then inclined by the set angle, e.g. 40°.

If you inclined the truck crane using the outriggers in order to set the angle, align it horizontally again.

• Fully retract the main boom. While doing so, the swing-away lattice must not touch the ground (raise it now and then if necessary).

• Set the head of the swing-away lattice down on

G Setting the angle to 0°

Risk of overturning when truck crane is standing at an angle!

After setting the angle, always check whether the truck crane is aligned horizontally.

In this way you prevent the actual working range deviating from the permitted working range, leading to the truck crane tipping over.

5 Swing-away lattice 5.12 Rigging work – Derricking the swing-away lattice

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 available space, the condition of the terrain or a limitation on the telescoping due to the current rigging mode, it may occur 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.

G

Risk 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. Make

Input

• Enter the current rigging mode for operation with a rigged swing-away lattice.

Use either the corresponding RCL code (2) in accordance with the lifting capacity table (1) or via individual components (3).

If you enter the current rigging mode via the individual components then you must also additionally enter the designation of the length of the swing-away lattice from the lifting capacity table. The length is entered there in this form.

• Enter the current reeving method on the swing-away lattice for the hoisting gear whose hoist rope is reeved on the swing-away lattice at the RCL.

• Confirm the entry.

H Shutdown

The lifting capacity for the RCL code is enabled once the telescopic sections are locked.

Operation with the swing-away lattice is monitored by the RCL. When operating with the swing-away lattice, RCL shutdowns may occur for the Operating manual same reasons as when operating with the main boom; GMK3050LB.

à

In certain rigging modes, the RCL shuts down when lifting loads 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).

– During main boom operation If a hook block (3) is reeved at the swing-away lattice, then the displayed current load (1) is influenced by – the weight of the lifted load (2), – the weight of the swing-away lattice (4) and – the weight of the hook block (3).

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

Do not override the RCL when lowering the boom into the horizontal position.

If the RCL is overridden, crane operation is not monitored and the truck crane will overturn if it moves outside 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; Rigging tables – swing-away lattice.

5.13.3

S

Telescoping with a rigged swing-away lattice Risk of overloading the main boom!

If you are telescoping the main boom with the rigged swing-away lattice, you must not simultaneously slew the superstructure.

That prevents the main boom from being overloaded by additional lateral forces and increased vibration.

Telescoping of the main boom with a rigged swing-away lattice (in the working position) is monitored by the RCL. Telescoping is only enabled 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; Rigging tables – swing-away lattice.

Checking the wind speed Strong winds can result in the truck crane becoming overloaded.

• Make sure to follow the instructions for checking the wind speed;

à Lifting capacity table, à Operating manual GMK3050LB.

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

The display (1) shows the current wind speed.

The maximum permissible wind speed (2) or the reduced wind speed (3) specified in the lifting capacity table applies to the confirmed rigging mode.

The display (1) flashes in colour in the vicinity of the maximum permissible value vmax (2) or (3).

– Yellow: about 90 - 100% of vmax reached – Red:

vmax exceeded

If the maximum permissible wind speed is exceeded An automatic shutdown does not occur if the maximum permissible wind speed is exceeded.

• Immediately stop crane operation.

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

24.01.2020

G

Risk of accidents due to excessively high wind speeds!

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

This will prevent the truck crane from overturning due to overload.

Risk of accidents when using an incorrect heavy load lattice extension!

Install only the heavy load lattice extension that belongs to the truck crane.

No other heavy load lattice extensions may be installed.

If the heavy load lattice extension is to be used on several truck cranes, the heavy load lattice extension must be adapted to the truck crane and marked with the corresponding serial numbers. Only have this modification carried out by Manitowoc Crane Care or an authorised GROVE dealer.

24.01.2020

The truck crane and the corresponding heavy load lattice extension are labelled with the same serial number (1).

Transport conditions

6.2.1

Transport conditions – Instructions for checking A correctly established transport condition is important for several operations.

– For safe rigging – For safe transport – For safe main boom operation

• Make sure that the corresponding transport condition is always established for the current operation.

• Always check the transport condition if you are requested to do so according to a checklist.

• Always check the transport condition before driving the truck crane with folded heavy load lattice extension.

• Always check the transport condition before using the main boom with folded heavy load lattice extension.

• Always check the transport condition before transporting the removed heavy load lattice extension with a separate vehicle.

• Observe the safety instructions in this section.

G

Risk of accidents during installing/removing and when rigging!

If a checklist refers to the inspection of the transport condition, it is assumed that all connections have been established as specified for the corresponding transport condition.

Make sure that the corresponding transport condition has been established before dealing with the next checklist item.

That prevents the heavy load lattice extension from falling down or swinging and hitting or crushing you.

Risk of injury!

Before transport, ensure that all cables and pins are securely fastened in the clamps and cannot come loose during driving. Additionally fasten the cables if necessary.

That prevents the sections from falling down while driving and injuring or even killing persons.

Risk of damage to the heavy load lattice extension and main boom!

Always make sure that the corresponding transport condition has been established before driving the truck crane with a folded heavy load lattice extension or main boom operation.

That prevents the heavy load lattice extension from hitting the main boom.

Risk of damage to the heavy load lattice extension!

Always secure the heavy load lattice extension by tying it down with suitable belts when it is transported on a separate vehicle. That prevents the heavy load lattice extension from tipping over and becoming damaged during transport.

Operation with heavy load lattice extension 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 need for a rigged or folded heavy load lattice extension.

6.9.1

Setting the RCL

Input

• Enter the current rigging mode for operation with a rigged heavy load lattice extension.

Use either the corresponding RCL code (2) in accordance with the lifting capacity table (1) or via individual components (3).

If you enter the current rigging mode via the individual components then you must also additionally enter the length (1) and the angle (2) of the heavy load lattice extension.

• Enter the current reeving on the heavy load lattice extension for the hoist whose hoist rope is reeved on the heavy load lattice extension at the RCL.

24.01.2020

• Confirm the entry.

6 Heavy load lattice extension 2.0 m (6.6 ft) 6.9 Operation with heavy load lattice extension

Shutdown

Operation with the heavy load lattice extension is monitored by the RCL. When operating with the heavy load lattice extension, RCL shutdowns may occur for the same reasons as when operating with the main boom; Operating manual GMK3050LB.

à

In certain rigging modes, the RCL shuts down when lifting loads are lighter than the maximum load bearing capacity specified in the lifting capacity table.

– During operation with the heavy load lattice extension If a hook block (3) is reeved in 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).

– During main boom operation If a heavy load lattice extension (4) is installed, then the displayed current load (1) is influenced by – the weight of the lifted load (2) and – the weight of the heavy load lattice extension (4) and – the weight of the hook block (3).

6.9.2

G

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

Do not override the RCL when lowering the boom into the horizontal position.

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

The prerequisites for permitting raising and lowering of the main boom with a rigged heavy load lattice extension 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; Rigging tables – heavy load lattice extension.

à

Note that the hook block or load can hit the heavy load lattice extension or the main boom when using large boom angles, 0° angle and short lifting gear.

The RCL switches off the raising of the boom when the minimum permitted working radius has been reached.

6.9.3

S

Telescoping with a rigged heavy load lattice extension Risk of overloading the main boom!

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

That prevents the main boom from being overloaded by additional lateral forces and increased vibration.

Telescoping of the main boom with a rigged heavy load lattice extension (in the working position) is monitored by the RCL. Telescoping is only enabled 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 heavy load lattice extension; Rigging tables – heavy load lattice extension.

Checking the wind speed Strong winds can result in the truck crane becoming overloaded.

• Make sure to follow the instructions for checking the wind speed;

à Lifting capacity table, à Operating manual GMK3050LB.

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

The display (1) shows the current wind speed.

The maximum permissible wind speed (2) or the reduced wind speed (3) specified in the lifting capacity table applies to the confirmed rigging mode.

The display (1) flashes in colour in the vicinity of the maximum permissible value vmax (2) or (3).

– Yellow: about 90 - 100% of vmax reached – Red:

vmax exceeded

If the maximum permissible wind speed is exceeded An automatic shutdown does not occur if the maximum permissible wind speed is exceeded.

• Immediately stop crane operation.

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

24.01.2020

G

Risk of accidents due to excessively high wind speeds!

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

This will prevent the truck crane from overturning due to overload.

Information about main boom operation when the heavy load lattice extension is installed In transport position During main boom operation with a folded heavy load lattice extension, the loads specified in the lifting capacity table are reduced and displayed on the maximum load RCL display.

H

The lifting capacity tables contain information for operations planning specifying the values which must be subtracted from the specified maximum load bearing capacities for certain rigging modes; Remarks about working with the heavy load lattice extension.

à

In working position You must enter an RCL code for the main boom without a heavy load lattice extension 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 is provided in the lifting caRemarks on working with the heavy load lattice extension. pacity tables;

The lifting capacities specified in the lifting capacity table are reduced for main boom operation with rigged heavy load lattice extension. The lifting capacity tables contain information for operations planning specifying the values which must be subtracted from the specified maximum load bearing capacities for certain rigging modes; Remarks about working with the heavy load lattice extension.

à

The RCL display does not display the reduced values correctly.

That means that the displayed value can deviate from the value that was previously calculated during operations planning.

24.01.2020

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.

G

Risk of accidents if the RCL is overridden!

Do not under any circumstances override the RCL. If the RCL is overridden, crane operation is not monitored and the truck crane will overturn if it moves outside the permissible working range.

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

The display (1) shows the current wind speed.

The maximum permissible wind speed (2) or the reduced wind speed (3) specified in the lifting capacity table applies to the confirmed rigging mode.

The display (1) flashes in colour in the vicinity of the maximum permissible value vmax (2) or (3).

– Yellow: about 90 - 100% of vmax reached – Red:

vmax exceeded

If the maximum permissible wind speed is exceeded An automatic shutdown does not occur if the maximum permissible wind speed is exceeded.

• Immediately stop crane operation.

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

24.01.2020

G

Risk of accidents due to excessively high wind speeds!

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

This will prevent the truck crane from overturning due to overload.

G Prerequisites

Risk of accidents due to incorrect procedure!

Before turning loads, observe all the prerequisites specified in this section and proceed exactly as described. This way, you avoid accidents due to overload.

– The main hoist rope must be reeved on the main boom.

– The auxiliary hoist rope must be reeved on the lattice extension.

24.01.2020

– The main hoist rope must be reeved with at least the same number of lines as the auxiliary hoist rope.

8 Turning loads over 8.1 Setting the RCL

8.1

Setting the RCL

Entering the reeving

Before lifting the load, you must enter the number of currently reeved lines for both hoists at the RCL, so that the data is immediately available should you subsequently wish to switch over to the main hoist after turning the load over.

Main hoist

• Select the symbol (1) and confirm your selection.

• Select the currently reeved number of lines, for example 3.

• Confirm the entry.

Auxiliary hoist

• Select the symbol (2) and confirm your entry.

• Select the currently reeved number of lines, for example 2.

• Confirm the entry.

Switching over to the auxiliary hoist

The load must first be lifted using the auxiliary hoist.

Turning a load over requires the use of both hoists simultaneously.

The RCL always uses the reeving data for the first hoist to be switched on.

• Switch off both hoists – symbols (1) and (2) turn red.

• Switch on the auxiliary hoist – symbol (2) turns green.

• Switch on the main hoist – symbol (1) turns green.

• Enter the RCL code that corresponds to the current rigging mode according to the lifting capacity table for the rigged lattice extension.

24.01.2020

The RCL now takes into account: – the reeving for the auxiliary hoist and – the lifting capacity tables for the lattice extension.

Before turning a load over, check that this procedure is in accordance with the regulations in the country in which you are working.

• Check that all the prerequisites have been met;

à Prerequisites, p. 8 - 1.

• Check if the RCL is correctly set;

à Prerequisites, p. 8 - 1.

G

Risk of accidents due to overloading!

Make sure that the RCL is set for operation with the lattice extension during the entire procedure and move the load only at minimum speed.

That prevents the crane from being overloaded.

H

Once the load is suspended on two hooks, there will be slight deviations on the Current load display. However, these deviations are on the safe side with regard to an RCL shutdown.

Turning a load over is performed the same way, regardless of which of the permitted lattice extensions is used. In this section the figure shows a lattice extension, which is used to symbolically represent all the other options.

• (A) – Lift the load completely with the lattice extension.

• (B) – Sling the load additionally at the main boom.

• (C) – Lift the load with the main hoist until both the slinging points are at the same height.

• (D) – Lower the load with the auxiliary hoist until the load is completely suspended from the main hoist rope.

• Detach the auxiliary hoist rope from the load.

G G G G

Risk of accidents due to partially obstructed view of the truck crane!

When driving the truck crane, always stay in visual or radio contact with a banksman who can observe the parts you are unable to see, for example, the erected main boom in the 0° to the rear position.

9 Driving with a rigged crane 9.2 Driving distance

9.2

Driving distance The driving distance must be level. Uneven surfaces cannot be compensated for with the level adjustment system.

The entire driving distance must be level. The rigging modes and axle loads specified in this chapter are only valid for driving distances that are without sloping ground in longitudinal and lateral directions.

The ground must be stable enough to bear the axle loads.

24.01.2020

If the surface pressure of the tyres exceeds the permissible load on the ground, the surface area of the tyres must be increased by packing stable material (e.g. wooden planks).

9 Driving with a rigged crane 9.3 Permissible rigging modes and axle loads

9.3

Permissible rigging modes and axle loads

Notes

Depending on the rigged counterweight and lattice extension, you must move the superstructure, the main boom and the lattice extension into certain positions so that the permissible axle loads are not exceeded.

S

Risk of damage to the axle lines!

Move the superstructure, the main boom and the lattice extension into the specified positions only. This prevents excessive strain on the axle lines.

• Enter the RCL code for the actual rigging mode and actual outrigger span of the truck crane in accordance with the lifting capacity table.

G

Risk of accidents if the RCL is overridden!

Always enter the RCL code for the current rigging mode. All specified positions are within the monitored working ranges.

If the RCL is overridden, the truck crane may overturn even if you move it into the positions specified.

• Move the superstructure, the main boom and the lattice extension into the position specified for the rigged counterweight in the following table.

• Tie down the hook block so that it cannot swing around.

Notes on the tables

à

Note on the specified angle ranges The specified maximum axle load is only reached at the limits of the listed angle range for the main boom, e.g. at 20° or 70°. If the maximum axle load is reached at the front, it will be below the maximum value at the rear and vice versa.

The axle loads are below the specified maximum axle loads within the listed angle range.

24.01.2020

H

All axle loads specified apply to 445/95 R 25 (16.00 R25) tyres on steel rims. In the case of different tyres, the axle load changes by double the weight difference of a Operating manual GMK3050LB, section Technical data, Spare wheel. wheel;
