Safety facilities of the XR S hooklift equipment
To increase safety, the control system has safety features to prevent incorrect movements
of the body so that the load can be kept under control.
The hydraulic cylinders are provided with load holding valves that ensure a controlled
movement of the XR S equipment. In addition these valves serve as a safety feature in
case of the failure of hydraulic hoses.
The following functions have safety features:
• Hydraulic body locks cannot be opened during tipping.
• Hydraulic body locks cannot be closed during loading and unloading.
• If the body locks are closed, it is not possible to move the hook arm.
• Moving the hook arm is not possible during tipping.
• When tipping, the rear frame and the middle frame are locked together by
the tipping lock. The lock operates mechanically.
• Tipping action cannot be initiated if the hydraulic body locks are open.
• The hook arm stops in two positions:
• Fully forward - this is when carrying an ISO container OR
during the stowing/unstowing operation = CONTAINER HOME POSITION.
• Approx 350 mm rearwards - this is when carrying a atrack/body OR
when empty = FLATRACK HOME POSITION.
