construction hoist

详情

1.�The series construction hoist�s transmission mechanism is on the top of the cage and so that it makes the hoist�s operation and starting more stationary and low-noise, convenient maintenance, accurate and stationary engagement of gear and rack , long service life.
2.�Tow set of Model YZEJ.A**2M*4 high-performance electric motors are applied in the reansmission ***** devices is independent of each ***** have two types:A)double-motor and double-reduction gear;B)three-motor and three-reduction gear, Each motor is equipped with direct current electromagnetic brake friction couple has the function of automatically tracking braking-gap and its braking is stationary and reliable, the reduction gear is of worm and worm wheel with planar quadratic ring envelopes and it has advantage of compactness, high-efficiency large-bearing capacity, durability and so on.
3.�Safety devices are perfect and reliable to ensure the hoists safe operation.
4.�there are two type of hoisting cage(with driving cap or not), three type of cable system(cable trolley with independent rail, cable trolley whose rail is rail frame itself and auto winding roller), two type of anchorage frame(directly anchorage frame with back pipes)for selecting.
5.�Frequency conversion building hoist has such traits:Starting and braking are steady with no ***** lifting speed can be controlled.Starting current is lower than rated ***** mechanical wear and tear is reduced evidently.Power saves efficiently.
