Safety mechanisms
– An enclosed truck geometry with rounded edges ensures safe truck handling. The
overhead guard protects the driver from falling objects.
– The drive wheel and the load wheels are protected by a solid skirt. A slight danger
nevertheless remains for third parties.
– The Emergency Disconnect immediately disables all truck operations in
hazardous situations.
– Travelling, lifting and lowering can only be activated when the deadman button is
pressed.
– Traverse and swivel operations can only be activated when the deadman button is
not pressed.
– Line brake safety valves in the lift cylinders stop the load lowering speed in the
event of a hydraulic system failure.
Deadman button
After the truck is ready for operation (see page 139 or see page 140) the deadman
button in the footwell must:
– be pressed and held down to allow the driver to carry out travel and hydraulic
operations with the industrial truck. Lifting and travel are inhibited if the driver
takes his foot off the foot switch. Steering and braking remain enabled. When the
deadman button is released and the industrial truck is stationary, the parking
brake engages (prevents the truck from rolling away).
– not be pressed to allow the driver to carry out traverse and swivel operations work
with the industrial truck. Steering and braking remain enabled. When the
deadman button is released and the industrial truck is stationary, the parking
brake engages (prevents the truck from rolling away).
