■Safety device
-Magnet (Electromagnetic) brake
Disc type DC brake is applied for winding-up and trolley.
Lining made from Non-asbestos material with excellent abrasion
resistant performance is applied and so can be used for long
time without anxiety. Their construction is very simple and easy
for the brake gap adjustment. Easy usage and performance are
improved remarkably.
-Dual upper limit switch
The control circuit is cut off by the first upper limit switch to stop
lifting. In the case of reverse phase operation, reverse winding
or short-circuit the second upper limit switch cut off the main
circuit, of the hoist motor.
-Load limiter (option)
Overload preventing device through electric current detecting
system.
-Power line sensor (option)
Contact-fusion detecting device. Voltage converter will be
required, if the power source for main circuit is NOT 3-phase,
200V (50Hz/60Hz). Consult us.
-Thermal unit (option)
Detecting the winding temperature of the motor, this is a safety
unit to stop the motor when the temperature exceeds the limit.
