Traction MRL

Description

Schumacher's MRL elevators are ideal when space for a machine room is not available. In addition, MRLs are economical because they require less power, when compared to traditional geared traction equipment. Also, Traction MRLs eliminate problems associated with hydraulic equipment (i.e. soil corrosion, noise, and smell).
