This truck crane is equipped with a safety har-
ness (1) on the main boom. The safety harness
is fixed securely to the main boom.
The safety harness consists of two ropes with
spacers and wear pads.
Always secure yourself with the safety har-
ness and your personal protective equipment
when you have to step on the main boom,
e.g. to rig the rope from the main hoist.
s
Safety harness on the main boom
GRisk of accidents when stepping
Read through the procedure in this section before stepping between the
main boom and the stand surface or between the stand surface and the
main boom.
GRisk of accidents due to unsuitable fall prevention safety system
Always secure yourself with a fall prevention safety system that is permis-
sible in the country in which you are working and includes a shoulder, waist
and seat belt with a two-point catch belt.
The fall prevention safety system must ensure that you are always secured
against falling when you step on the main boom.
SRisk of damage to the safety harness.
Never fasten loads or other objects to the safety harness. This will prevent
damage and overload to the safety harness.

Prerequisites The safety harness only ensures secure protection from falling if a suitable
fall prevention safety system (personal protective equipment) is worn. This
fall prevention safety system must be attached to the safety harness on the
truck crane.
Requirements The fall prevention safety system must correspond to the requirements of
the applicable standards and regulations in the country in which you are
working. If you are unsure, find out which standards and regulations apply
for the country in which you are working.
The fall prevention safety system must consist of:
– a combined shoulder, waist and seat belt,
– a catch belt with two lines for fastening at feet height.
HOnly one person at a time is allowed to be secured by the safety harness.
The weight of the person to be secured must not exceed 140 kg (309 lbs).
If you are unsure about which type of fall prevention safety system is
required, please contact Manitowoc Crane Care.

Attaching/detaching fall prevention safety system
to/from safety harness
Attachment
All points designed for fastening a fall prevention safety system are marked
with a symbol.
When stepping, observe the following procedure so that you are always
secured.
•Use the available ladders and access lad-
ders on the truck crane to climb up;
àOperating manual.
•Make sure you always attach one line of the
fall prevention safety system with the safety
harness before entering the main boom.
•Attach the second line of the fall prevention
safety system with the safety harness once
you are located on the main boom.
s
GRisk of accidents due to incomplete safety system
Make sure you always attach one line of the fall prevention safety system
with the safety harness before stepping onto the main boom.
This will prevent falling due to an incomplete safety system.

Detachment
When stepping, observe the following procedure so that you are always
secured.
•First of all, detach the line that faces away
from the ladder or access later.
You may only detach the second line of the
catch belt once you have reached a secure
position.
•Use the available ladders and access lad-
ders on the truck crane to climb down;
àOperating manual.
GRisk of accidents due to incomplete safety system
Only detach the second line of the catch belt once you have reached
a secure position on a ladder or access ladder.
This will prevent falling due to an incomplete safety system.

Inspecting/replacing safety harness
HMake sure your personal protective equipment is also regularly inspected.
In order to do this, observe the information provided by the manufacturer.
Inspection The safety harness on the main boom must be inspected for damage at reg-
ular intervals.
•Check all fastening and connecting parts for
damage, wear, mobility and deformations.
Replacement Make sure damaged, worn, or deformed fastening or connecting parts are
immediately replaced by Manitowoc Crane Care or an authorised GROVE
dealer or your repair crew.
HThe safety harness must always be replaced completely following stress
caused by a fall, even if no damage can be detected.
GRisk of accidents if inspections are not carried out
Make sure the safety harness is inspected regularly.
This will prevent component failure in cases of danger.
A safety harness only ensures protection from falling if it is regularly
inspected.

The storage compartment (1) for anemome-
ters and air traffic control lights described in
the accompanying operating manual is only
available for certain versions of truck crane.
In this case the rod (2) is fastened to the main
boom head for transport and the anemometer
(3) and air traffic control lights are transported
in the crane cab.
s
Anemometer and air traffic control light
Transport
SRisk of damage during on-road driving
Always store the anemometer and the air traffic control lights in the crane
cab before on-road driving and fasten the rod to the transport retainer.
This prevents the specified overall height from being exceeded at on-road
level, and the anemometer from getting damaged due to unfavourable air
currents.
