Check these options, if available:
– automatic return to the resting position
– locking of door/dock leveller (sensor) or safety
wheel chock
– warning signal system (optical/acoustic)
•
Carry out a visual inspection on:
– mechanical damages, rust formation and the
condition of the welded construction
– dirt and oil spills in the area underneath the
dock leveller. Remove any if present.
•
Make sure that no debris, stones etc. obstruct the
function of the hinges.
•
Provide sufficient slip resistance by keeping the
dock leveller platform clean and dry.
•
Do not use any aggressive cleaning agents or
thawing salts! Risk of corrosion:
•
Do not aim a high-pressure water jet at the
control system, the hydraulic system or any
electrical connections!
If you notice damages the dock leveller must be in-

slip resistance condition of the drivable surfaces
•
condition of the anti-slip coating/sound-absorbing
coating (optional) of the dock leveller platform
•
protective plate
•
maintenance support
•
screw connection and safety cotter pins of the
hydraulic cylinders
•
