Double Girder Top Quality Heavy Duty Insulation Type Electric Bridge Traveling Crane
Product Description
QY model insulating overhead crane is widely used in electrolyzing of nonferrous metal, aluminum and magnesium metallurgy workshops. This model crane is composed of box-type frame, crane travelling mechanism, trolley, electric equipment. In order to prevent the current of electrical equipment would through lifted parts endanger the driver of crane during working, the insulation equipment is set up at some suitable positions.
It has over three insulation parts to protect the current of electrical equipment from endangering the driver of the crane when working.This model crane belongs to heavy working grade, in order to secure safety; main hoist mechanism is matched with double brakes.
Safety protection system
1. Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible
2. Long and cross travel limited by means of preliminary and final limit switches or Wireless anti-collision device
3. Anti-falling protection for the Three-in-One electric motor of trolley and crane prevents from
