1.Lifting Motor
The compact wire rope hoist is designed according to FEM standards.
The lifting drive adopts low noise, high efficiency, easy
maintenance, aluminum three-stage parallel shaft gear reduction
motor, which is directly installed on the drum. The high-power
lifting motor with double-sided safety brake is available for users
to choose from two options: double speed and variable speed.
Chinese brand and SEW brand for option.
2. Gear Reducers
It adopts three-stage helical gear reduction. The gears and shafts
are made of alloy structural steel. The box body and box cover are
made of cast iron, with good vibration reduction and reliable
sealing.
Lightweight, compact structure, long wheelbase, easy to install.
Optimized electromagnetic design, small starting current and large
limit torque.Double friction surface safe braking, smooth and
vibration-free.Integrated design of drum bearing support and
lifting drive device.
3. Wire Rope Drum
The drum is directly connected to the reducer, which makes the
start-up smoother. One end of the drum is connected with the
lifting reducer and motor, and works with the suspension device
through the wire rope; the other end is equipped with a height
limit device.
4. Control method
Flexible control: supports remote control by handle, cab operation
or automation integration (such as linkage with PLC).
Frequency conversion control (optional): realizes stepless speed
regulation, precise positioning, and reduces load shaking.
5. Environmental adaptability
High temperature resistant/explosion-proof design (optional): can
be customized for metallurgical high temperature workshops or
flammable and explosive environments.
Low maintenance requirements: automatic lubrication system, sealed
bearings and other designs reduce the frequency of daily
maintenance.
6. High efficiency and energy saving
Energy feedback technology (some models): recovers electrical
energy when lowering the load to reduce energy consumption.
Low noise operation: optimize the design of gears and motors to
meet environmental protection requirements.
