Additional equipment 4.3-3
When you are working with load carrying equipment or accessories
such as load hooks, mechanical extensions, winch components, etc.,
always make sure that the equipment has been properly secured.
Always use the proper bolts and securing elements (cotter pins, lock
nuts, etc.) for the load carrying equipment or accessories.
Hook
•
On your crane only use load hooks which match your crane and the load
to be lifted.
•
The lifting capacity of the load hook and the shackle must correspond to
the maximum lifting capacity of the crane.
•
Fasten and secure the load hook properly
•
Ensure that the safety catch closes again by spring pressure after the load
has been hooked.
Working with hydraulic ancillary equipment
A range of ancillary equipment (grab, rotator etc.) is operated hydraulically. Before using ancillary
equipment the respective maximum permissible operating pressure must be noted.
The hydraulic system of the ancillary equipment is coupled to the crane’s hydraulic system with screw
couplings. When using quick couplings make sure everything is clean (use dust caps). If the screw
couplings are connected, the dust caps are also to be screwed.
Connecting screw couplings:
• Switch off pump
• Remove pressure from the lines by operating the control levers in both switching positions.
•
Remove dust caps from the couplings.
• Screw couplings until tight.
• Connect dust caps
Couplings, hoses or leaking oil can become so hot from the heated
oil that there is a risk of burns. Carelessly screwed couplings can
result in oil leakage and the consequent pollution of the
environment. The loss of pressure impairs the function of the
ancillary device or causes it to fail completely.
