crane geared motor, 1.long service life, 2.heat treated and fracture resistant, 3.smooth,stable operation, 4.high performance - details see: https://www.machineto.com/new-pro-crane-electric-ac-geared-motor-10238616

KD030 unbuffered crane geared motor

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 make it high accurate. It possesses high abrasion and fracture resistance. The safety factor is up to 5 times or more and long product life.

2.Buffer

Adopting soft start and fly steel act to produce high inertia movement. Both starting and braking are stable and smooth, which make goods not shaking.

3.Motor

High performance,high torque,motor itself ensures quick heat dissipation, and high resistant 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.
