Overfit - Gearless

Traction elevators according to Overfit - Gearless model are machine room-less systems: the hoist with permanent magnet motor and reducerless is located in the headroom. The control panel is located in the top landing door frame or within the shaft. Overfit - Gearless model traction elevators comply with UNI EN81-1:2005 harmonised standards (corresponding to EN81-1:1998 + A2:2004), and therefore comply with 95/16/EC Elevator Directive. They also comply with the requirements of the 89/336/EC Electromagnetic Compatibility Directive and the 98/37/EC Machinery Directive, where applicable. This elevator model complies with EN81-1:2005 harmonised standard and thus with 95/16/EC Elevator Directive. It also complies with EMC (Electro Magnetic Compatibility) Directive 89/336/EC and 98/37/EC Machinery Directive.
Benefits
This is a space-saving system thanks to the lack of machine room. The machine is fully contained within the shaft, supported by guide rails. The whole elevator load is backed by the car and counterweight guide rails and neither bearing beams to be fixed to the shaft walls nor other masonry works are required. The service cabinet, next to the top landing door, has a reduced depth and minimum aesthetic impact. Thanks to the gearless motor and the speed frequency control guaranteed by a high quality inverter, high ride quality, noiselessness within the car and building, better system performance, reduced power installation and consumption (also in terms of energy costs), less mechanical stresses and motor temperatures are achieved.
