Load Safety Device
The load safety devices include an
emergency shut-off valve and an overload
warning device. The emergency shut-off
valve stops the boom or arm part way
through a fall. The overload warning device
sounds an alarm when an excessive load is
applied.
Emergency shut-off valve
When the hose of the boom or arm cylinders
are ruptured and the boom or arm falls, the
emergency shut-off valve is activated and
stops the boom or arm part way through the
fall.
WARNING
If the boom or arm drops and the
emergency shut-off valves are activated,
immediately move away from the
suspended object.
Boom / Type A
Boom / Type B
Arm / Type B
If the emergency shut-off valves (1) or (2)
are activated, immediately set the operating
lever to the neutral position. Do not move
the operating lever to the boom or arm
lowering side. Contact a Takeuchi dealer for
maintenance.
