1.5 KW geared motor for chain lifting hoist end truck:
1. Reduction gear
The gear box is made of high strength cast iron (FC25), and manufactured by computer numerical control machinery (CNC LATHE&CNC machine center). The gear is made of Ni-Cr-Mo alloy steel (SNCM220&SCM415) with carburization process. The shaft is manufactured by alignment and grinding.
High accuracy,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 is simple for radiation, high-pressure resisting more than"1500v", light current, compact-sized, powerful output, available for high frequency.
4. Electromagnet brake
With direct-type electromagnet brake, control can be adjusted with screw, high abrasion brake leather, long service life, safety, and never be falling off.
