Leroy-Somer holds a leading position in Europe in the segment of production of electric motors for crane and lifting equipment. In this field, electric drives in most cases operate in severe modes with overloads, may be adversely affected by harmful environmental conditions - typical for port and marine cranes, metallurgical and chemical industries. In this regard, it can be stated that the operation of the electric motor in these conditions is a constant "strength check". In no case should a malfunction in the equipment cause an emergency. Increased reliability requirements are the main working conditions in this segment.
At Leroy-Somer, the Moteurs PATAY structural division is engaged in the development and production of electric motors for cranes, lifts, and elevators. All electric motors are equipped with electromagnetic brakes of their own production.
