Safety
2.8.2 Hydraulic
Check all hydraulic hoses and connection for tightness before every operation. Only experts are
allowed to replace faulty parts (depressurized).
Ensure a clean working environment before opening the hydraulic connection.
The hydraulic hoses must be free of breaks and abrasion. Take care that there are no outstanding
edges, where the hoses could hook in.
The operator of the device is responsible for a constant line pressure, which is necessary for
the working with this device.
Only under these conditions is a safety gripping, lifting and transporting of the gripping goods
with this device ensured.
2.9 Safety procedures
2.9.1 General
•
The use of the device is only permitted in proximity to the ground.
Do not swing it over people heads.
•
The stay under lifted load is forbidden. Danger to Life!
•
The manual guiding of the device is only allowed at the handles.
•
While using the device the stay of persons in the working area is forbidden. Except it is
indispensable, caused of the way of using the device, e.g. if the device must be leaded by hand.
•
Jerky lifting or lowering of the device with or without load is prohibited, as well as driving fast with
the carrier device/lifting device over uneven terrain! In general, with the load lifted, drive with the
lifting equipment (e.g. excavator) only at walking speed - avoid unnecessary vibrations.
Danger: Load could fall down or load handling equipment could be damaged!
•
Do not lift any components off-centre (always in centre
of gravity), because that could fall down.
•
The device should not be opened if the opening path
of the gripping arm is blocked by a resistance (e.g.
other concrete blocks or the like)!
•
The operator is not allowed to leave the control unit as
long as the device loaded with load. The load must
always be in the range of vision of the operator.
•
Never exceed the carrying capacity/working load limit
(WLL) and the nominal width/gripping range of the
device.
•
Do not pull out stuck or tightened loads with the
device.
•
Never pull or drag loads sideways. Otherwise parts of
the device could be damaged.
