■ Fuse valve
This valve is provided on the hydraulic cylinder to prevent
a rapid outflow of oil due to a cause, such as a damaged
hydraulic circuit.
■ Relief valve
This valve releases the hydraulic pressure to prevent
damage to the lift or an accident when the pressure in the
hydraulic circuit increases abnormally during lift-up of a
vehicle exceeding the lift capacity or due to a problem.
This valve is contained in the gear pump.
■ Thermal relay
When detecting an overload current, this relay breaks the
electric circuit to prevent burning of the motor. This relay is
contained in the magnet switch.
