Electric traction lift with the gearbox in the pit and direct suspension (1:1)

Lifts in compliance with ELEKTROFIT models are characterised by the gearbox placed in the pit. The control panel, main supply and light switches are placed inside a portal in a landing door. Inside a portal in a landing door there are all the components normally installed in a standard machine room (the control panel, main and light switches, thermostat for temperature detection, lighting lamps, etc.).

Most of the lift load is applied to the car and counterweight guide rails, thus no beam connecting to the shaft walls is necessary.

In the ELEKTROFIT models the noise and vibrations source caused by the machine are limited by the fact that they are at the bottom of the shaft. Owing to the frequency control system, using a high quality inverter, a high standard of ride comfort, reduced current consumption peaks and consequent energy and money saving, reduced mechanical stresses and reduced temperature of the gear motor are obtained.

Rescue operations can be carried out from outside the shaft, once the portal front panel has been opened, and it includes an auxiliary operation assuring the functioning of the system even in case of failures such as motor main winding, brake solenoid, control panel cards and main inverter. The auxiliary operation devices operate even in case of power failure. The gearbox is fixed in the pit, placed on a frame, therefore its position is extremely stable and maintenance operations are carried out by standing on the floor.
The control of the car position during gearbox maintenance is assured by a safety system provided.
