3 Telescopic swing-away lattice extension
3.1 Supplement to the operation of the GMK 6300 with the
telescopic swing-away lattice extension folded at the
side
When the telescopic swing-away lattice extension is folded at the side, the
prerequisites change
– for telescoping when working with the main boom and
– for driving the truck crane.
Observe the information in the following sections concerning this.
3.1.1 Changed prerequisite for telescoping
S
Risk of damage to the hoses of the hydraulic connection.
Ensure the hydraulic connection of the lattice extension is separated before
telescoping the main boom.
This prevents the hydraulic connections being torn during telescoping;
à Establishing/disconnecting the hydraulic connections, p. 3 - 46.
If the telescopic swing-away lattice extension is mounted sideways onto the
GMK 6300 main boom, it can be put into two positions:
– Into the position driving,
– Into the position working with the main boom.
The telescopic swing-away lattice extension's position is electrically moni-
tored. The telescoping of the main boom will only be released if both of the
following lights are not on:
3 – The indicator lamp Lattice extension in driving position must not light up;
à Additional operating and display elements in the crane cab, p. 3 - 7.
Ö – The warning lamp Telescoping main boom closed must not light up;
à Additional operating and display elements in the crane cab, p. 3 - 7.
H
Both the lamps are installed together with other display and operating ele-

3.5 Components and identification
Components When delivered, the telescopic swing-away lattice extension has the follo-
wing components (see diagram on next page):
– The foot section
– The head section (inclinable part)
– The adapter unit (for mounting on the main boom head)
– A levering tool to connect the hydraulic quick couplings
Identification The telescopic swing-away lattice extension is designed for the truck crane
for which it was delivered. The telescopic swing-away lattice extension
parts belonging to the truck crane have the same serial number as the truck
crane. All individual components are identified by serial numbers.
S
Operate the truck crane only with the parts of the telescopic swing-away
lattice extension which have the same serial number as the crane.
The RCL is set only for this telescopic swing-away lattice extension.
This prevents malfunctions and damage.
H
For technical reasons, a truck crane may only be set with one telescopic
swing-away lattice extension.
If you wish to use the telescopic swing-away lattice extension on several
GROVE truck cranes, the telescopic swing-away lattice extension sections
must be adjusted for the corresponding cranes and labelled with all of the
respective serial numbers.
S
The adjustment of the telescopic swing-away lattice extension may only be
carried out by CraneCARE.

3.9 Description of the rigging work
3.9 Description of the rigging work
3.9.1 Preparing the truck crane for rigging
Prerequisites for The following requirements must be met before the rigging of the lattice ex-
rigging tension is started:
– The lattice extension must be mounted at the side on the main boom and
must be in transport condition.
– The counterweight combination required according to the Lifting capacity
table for the planned operation with the lattice extension is rigged.
– The truck crane is supported by the outrigger span required acc. to the Lif-
ting capacity table for the planned operation with the lattice extension and
is level.
– The telescoping cylinder is locked in telescopic section IV and is retracted
as far as possible just before the start of rigging so that all telescoping
parts are fully retracted.
– The hook block is unreeved until the hoist rope extends to the ground on
the left side of the main boom.
– The hoist rope is unreeled from the main boom head approx. 10 m (33 ft)
wide towards the front (until the hoist rope stop for angling).
S
Risk of damage to the hoist rope.
Always keep the hoist rope on the left side of the main boom going down
to the ground. In this way, you will prevent that the hoist rope from damage
by getting stuck on the retaining part while being tightened.
Prerequisites for Before you lower a lattice extension or the boom extension into a horizontal
unrigging position, the following requirements must be met:
– No other load is raised apart from the hook block.
– The counterweight version required according to the Lifting capacity table
for the planned operation with the lattice extension is rigged.
– The truck crane is supported with the outrigger span prescribed for ope-
ration with the rigged lattice extension according to the Lifting capacity ta-
ble.
– The main boom is fully retracted (0/0/0/0).
2007.12.06
– The RCL code for operation with the rigged lattice extension must have
been entered.

3.9 Description of the rigging work
3.9.5 Pin connection to swing the lattice extension
The pin connection for swinging the lattice extension is made and discon-
nected between the bearing points of the foot section and of the adapter
unit on the right side of the main boom.
The connection must be made so that you can swivel the lattice extension
in front of the main boom head during rigging or onto the basic section du-
ring unrigging.
The connection must be disconnected so that you can swivel the lattice ex-
tension into the working with the main boom position.
G
Risk of accidents due to falling parts.
Always secure the pins both in the bearing points and in the holders using
retaining pins.
This prevents unsecured pins from becoming loose, falling out and causing
injuries.
H
If the bearing points for the slewing connection do not align, you can align
the lattice extension by turning using the mobile switch unit; à
p. 3 - 63.
Creating a slewing The connections on the bearing points are made with pins.
connection The pins can be found in holders on the lattice extension and are secured
there with retaining pins.
• Release the retaining pins and remove the
two pins from the holders (3) and (4).
• Insert one pin into each of the bearing points
(1) and (2).
• Secure both pins with the retaining pins.

3.9 Description of the rigging work
Setting the angle This section describes the procedure for setting the angle.
The required pin connections for the different angles are illustrated in the
following section; à
p. 3 - 52.
When rigging
• Lift the lattice extension with the hoist rope until the inserted pins are re-
lieved.
• Remove the retaining pins and knock out the securing pins; à p. 3 - 52.
S
Risk of damage when putting down the head.
When inclining the lattice extension, never lower the main boom so much
that the head of the lattice extension touches the ground. If the lattice ex-
tension is put on the ground or moved on the ground, the lattice extension
can be damaged.
• Incline the lattice extension with the hoist into the required angle. Be sure
that the head section does not touch the ground when doing this.
• Make the necessary pin connections for this angle and secure all pins with
retaining pins; à p. 3 - 52.
When unrigging
• Lift the lattice extension with the hoist rope until the inserted pins are re-
lieved.
• Remove the locking pins at a 5° angle; à p. 3 - 52.
• Pull the lattice extension to a 0° angle with the hoist rope.
S
Risk of damaging the hoist rope when lowering.
If you have pulled the lattice extension to the stop into the 0° position with
the hoist cable, you always have to release some of the hoist rope before
you lower the main boom. In this position, the lattice extension can no lon-
ger compensate for the radius modification by inclining, the hoist rope is
loaded when lowered and may tear.
• Release a little of the hoist rope and do not lower the main boom so much
that the head section touches the ground.
• Make the necessary pin connections for the 0° angle and secure all pins
with retaining pins.

3.10 Working with the lattice extension
3.10.1 Raising and setting down the main boom with rigged lattice ex-
tension
S
Risk of overloading the main boom.
When raising and setting down the main boom with rigged lattice extensi-
on, operation in high-speed mode is not permitted.
This prevents the main boom becoming subject to increased vibrations and
becoming overloaded.
H
To raise and set down the main boom with a rigged lattice extension the
main boom must be fully retracted (RCL display 0/0/0/0) and the RCL then
switches automatically to the rigging program.
For raising and setting down, the following requirements must be met:
– The RCL code for the actual rigging mode is set on the RCL with
11 m or 19 m telescopic swing-away lattice extension selected.
– 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.
Raising • Derrick in the main boom to raise it.
Setting down • Derrick out to set down the main boom while making sure that the head
sheave is not pushed over the ground with the 19 m lattice extension.
S
Risk of damage when putting down the 19 m lattice extension.
When setting down, the head sheave of the lattice extension must not
touch the ground. Stop lowering the boom before that, or attach the lattice
extension to the hoist rope or an auxiliary crane to adjust the angle.
This prevents the lattice extension being pushed forward to the ground and
the extended section from being damaged.
