Electrical Wire Rope Hoist

Product Description

Hoisting motor - The non-ventilated type squirrel case *-phase ***** induction motor, having the high satrting torque and low starting current and low temperature rise. Hoisting Brake - The disc brake having the braking torque of **0% or more of rated load is provided to the ***** brake is realease with spring by power. The brake is holded even if power failure. It is magnetic type and is a good response. Two step upper limit siwtch - The sfety factor is 5 times or more under the consideration of sheave efficiency. Standard wire is 6xSes(*7)+FC for a long service life. Reduction gear: Since gear is made of SNCM**0 and S*5C and is treated with induction hardening, the surface is hard ( *0HR ~ *0HR) and inside is elastic. Gears are smoothly operated for an oil bath lubrication and superior to a wear and abrsion resistance. Fine machining of the drum grooves minimises wear on the rope, the return sheaves are resistance to wear.
