Competition 500 gearless traction lifts are provided with a reducerless, VVVF-controlled permanent magnet motor located in the headroom. The control panel is located in the top landing door frame or within the shaft. Competition 500 gearless traction lifts comply with UNI EN81-1:2010 harmonised standards (corresponding to EN81-1:1998 + A2:2004 + A3:2009), and therefore comply with 95/16/EC Lift Directive.
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 lift 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.
Besides the standard safety systems, specific devices for these machine room-less systems are provided. The passenger rescue operation is carried out from outside, after opening the cabinet front panel located in the top landing door frame.
An auxiliary manual operation can be carried out whenever one of the safety contacts has been released (safety gear, limit switch, bumpers, overtravel switch). This same operation can be carried out also in case of brake coil failure, by opening it with a mechanical system: this operation also allows the car movement towards the unbalanced load, with a reduced speed controlled by the motor windings.
A camera allows to watch the machine and traction pulley in order to check the car movement direction. Optionally, the mechanical operation is provided bringing the car to a landing and opening the doors. The machine is fixed in the headroom, above an appropriate frame connected to the car and counterweight guide rails in an extremely steady position. Machine maintenance operations are carried out inside the shaft, standing on the car roof. Car control and steadiness are guaranteed by a guide rail mechanical stop system. For the version with electric panel in the shaft and service cabinet at landing, the electric panel maintenance is carried out standing on the car roof as well.
