Important information
1.4 Organisational measures
1.4 Organisational measures
The operating instructions and the lifting capacity table should be kept in
the truck crane for immediate access and should not be removed from the
truck crane. You need to have read and understood the operation and safety
instructions in these operating instructions and to comply with them when
working.
In addition to the operating instructions and the lifting capacity table,
observe all general, statutory and otherwise applicable regulations con-
cerning accident prevention and environmental protection. You need to
have read and understood these and to work accordingly.
This includes:
β the use of hazardous materials,
β wearing protective clothing and equipment,
β traffic regulations or
β all regulations aplying to the ooertion of the crane.
Ensure that those appointed to work on the truck crane are given the infor-
mation required to carry out the work before starting operations. Give your
employees (e.g. banksmen, slingers, rigging personnel) appropriate in-
struction.
Ensure that the maintenance personnel possess the necessary know-how to
safely operate the crane. Ensure that the maintenance personnel have ac-
cess to the operating instructions.
Only properly trained or instructed personnel may carry out work on the
truck crane.
Responsibilities related to crane operation, rigging, maintenance and repair
work must be clearly defined.
Ensure that only the appointed employees operate the truck crane.
Do not leave long hair down or wear loose clothing or jewellery (including
rings) when working with the crane. These could get caught or pulled into
the unit and result in injury.
Use your personal protective equipment whenever necessary or prescribed.
Observe all safety and warning signs on the truck crane.
Ensure that all safety and warning signs on the truck crane remain legible.

3.2 Identification
3.2 Identification
The two-stage swing-away lattice extension is designed for the truck crane
with which it was delivered. The two-stage swing-away lattice extension
parts belonging to the truck crane have the same serial number as the truck
crane.
The following parts are identified by the serial number:
β the 12.5 m (41 ft) section on the fixed section,
β the 12.5 m (41 ft) section on the luffing section,
β the 9 m (30 ft) section.
S
Operate only two-stage swing-away lattice extension sections which have
the same serial number as the crane.
The SLI is only set for this two-stage swing-away lattice extension.
This prevents malfunctions and damage.
H
For technical reasons a truck crane may only be set with one two-stage
swing-away lattice extension.
If you wish to use the two-stage swing-away lattice extension on several
GROVE truck cranes, the two-stage swing-away lattice extension sections
must be adjusted for the corresponding cranes and labelled with all of the
respective serial numbers.
S
The two-stage swing-away lattice extension should only be adjusted by
your local GROVE Customer Support!

3.6 Description of rigging work
3.6.2 Checking the transport condition
For transportation you must establish certain connections between both
parts of the lattice extension. The connections which need to be established
depend on whether the lattice extension:
β is folded up at the side of the main boom for transportation or
β is completely removed for transportation.
Transport condition is when the lattice extension has been removed as de-
scribed in the corresponding checklists.
S
Be careful not to damage the lattice extension and the main boom!
Always put the lattice extension into transport condition before driving the
truck crane with a lattice extension folded at the side or working with the
main boom.
Only then is the lattice extension secured against slipping.
In this way you prevent the partly fastened lattice extension hitting the
main boom or the individual components of the lattice extension hitting
each other and becoming damaged.
You must check transport condition:
β After unrigging the lattice extension, before you drive the truck crane with
the lattice extension folded at the side or work with the main boom.
β Before installation and before rigging the lattice extension.
The corresponding checklists require that the lattice extension is in trans-
port condition.
The following paragraphs and the diagram show the necessary connections
for the transport condition with the lattice extension folded at the side and
removed.

Connection between 9 m (30 ft) section and main boom
The connection must be made:
β When rigging the 13 m (43 ft) swing-away lattice extension,
β for transportation when only the 9 m (30 ft) section is folded at the side
of the main boom.
The connection must be disconnected:
β When rigging the 22 m (72 ft) two-stage swing-away lattice extension,
β after operation with 13 m (43 ft) swing-away lattice extension when the
lattice extension needs to be removed.
Making connection
β’ Swing the 9 m (30 ft) section fully onto the
main boom.
β’ Attach the 9 m (30 ft) section to the main
boom with the pin (1).
β’ Secure the pin with the retaining pin.
Disconnecting connection
β’ Remove the pin (1) from the connection and
insert it in the bore (2).
β’ Secure the pin with the retaining pin.

lattice extension out, the load must be removed from the bearing points; p. 3 - 53.
If the 9 m (30 ft) section is swung in front of the 12.5 m (41 ft) section when
rigging the 22 m (72 ft) two-stage swing-away lattice extension, it must be
locked on the head of the 12.5 m (41 ft) section.
The securing pins for this connection are all in
the retaining sheet (1) on the foot of the 9 m
(30 ft) section and are secured with retaining
pins.
A securing pin (2) has already been inserted
for the swinging connection.

This section describes the installation and removal of the folded two-stage
swing-away lattice extension.
You can also install the two-stage swing-away lattice extension which has
been folded in front of the other in front of a 8 m (26 ft) section (e.g. when
you are changing directly from the 22 m (72 ft) two-stage swing-away lattice
extension to a boom extension).
H
An auxiliary crane must be used to install and remove the two-stage swing-
away lattice extension.
The securing pins (1) for the connection are in
the holders on the foot of the 12.5 m (41 ft)
sections and are secured with retaining pins.

β’ Sling the two-stage swing-away lattice
extension onto an auxiliary crane;
Γ Slinging points, p. 3 - 9.
β’ Lift the two-stage swing-away lattice exten-
sion in front of the 8 m (26 ft) section so that
the bearing points (2) and (3) align on both
sides.
β’ Insert the securing pins on both sides into
the bearing points (2) and (3).
β’ Secure all the pins with retaining pins.
Removing
β’ Sling the two-stage swing-away lattice extension onto an auxiliary crane;
Γ Slinging points, p. 3 - 9.
β’ Lift the two-stage swing-away lattice extension until the bearing points
are relieved.
β’ Release the pins and knock them out of the bearing points (2) and (3) on
both sides.
β’ Insert the pins into the holders on the 12.5 m (41 ft) section and secure
them with retaining pins.
