1,Reduction  gear

 The gear box is made of high  stress cast iron (FC25), and manufacture  by computer  numerical control machinery (CNCLATHE & CNC machine  center).  The gear is of Ni-Cr-Mo alloy steel(SNCM220 & SCM415) with carburization  process. The shaft is made by alignment and grinding . High accuracy  ,be durable and bumping. More than 5 times safety factor. Long working  life

2,Buffer

When soft starting, and after fly wheel acting, the movement of high inertia is Produced. No impactness this keeps crane stable, smooth and noiseless to stabilize the brake.

3,Motor

High performance of start torque, motor body heat is easy to dissipation. High-pressure resisting more than 1500V, light current, compact size, powerful output, available for high frequency working.

4, Electromagnet brake

With direct-type electromagnet brake control can be adjustable with screw  high abrasion brake leather, long service life, safety and never be falling off.
