1 Ton Dual Speed Underslung Chain Hoist Trolley

Dual Speed chain hoist refers to a special hoist which can switch freely between ordinary and slow speed. The dual speed electric hoist trolley has a small impact force when starting and stopping, and can operate very smoothly. 

It is suitable for some precision workplaces, for example, in some factories of carving and grinding tools, switching to the slow mode can achieve a height accurate to a few centimeters, achieving perfect carving.

Why we need dual speed chain hoist trolley

Dual speed controls via “under-the-cover” variable frequency drive for both single-phase and three-phase hoists.

Adjust the hoist to use at high speed when it's required, and when it needs to carry out processing work, adjust it at low speed. There is no need to cut off the power when adjusting so that to avoid the damage to the motor, which is caused by the secondary startup. And the operation will be more stable.
