Detailed Product Description

Typical application

Seaport, metallurgy, machinery, architecture, chemical, transportation, power supply, raliway and road construction

Features

1.Internal contracting brake control and monitor function

2.Separated power supply control for control circuit and power circuit

3.Speed increasing function for light load or without load can realize faster speed for sky-hook to improve the efficiency

4.Master-slave function for speed synchronization can realize speed equilibrium to keep two cranes in the same steps.

5.Master-slave function for power equilibrium to make two motors balance to lift one load through one reduction gear box
