This group of electric motors is designed to work with gearboxes in chain and rope hoists and cranes. Elprom Harmanli produces two main types of electric motors: cylindrical and conical analogs. The brake of the cylindrical motors is electromagnetic, DC, non-adjustable. Travelling motors are produced with different joining dimensions depending on the gearboxes they are coupled to. In addition, we can offer brakes with hand release and forced ventilation.
