1.Reduction gear

The gear box is made of cast iron(FC25) with high tension, and manufactured by computer numerical control machinery(CNC LATHE&CNC machining center),which lead it to accurate precision. The gear is made of Ni-Cr-Mo alloy steel(SNCM220&SCM415)with heat treatment of vacuum and carbonnitriding. The shaft is manufactured by alignment and grinding,which makes it high accurate. It possesses high abrasion and strike resistance. The safety factor is up to5times or more. The product-life is very long.Service life is long.

2.Buffer

Adopting soft starting and fly steel acting to produce high inertia movement. Both lunching and braking are stable and smooth, which makes goods not shaking.

3.Motor

High performance,high torque,motor itself ensures quick heat dissipation, and resistance to high voltage ranks more than 1500w.And it is also with other advantages:low current, small size, strong output power,and high operation frequency.

4.Electromagnetic brake

direct current brake possesses strong braking force.Bolt controls braking force directly, and adopts braking pad with high wear resistant to make it with high safety,long service life,and strong stablity
