LIFT COMPONENTS

COASTAL LIFT SUPPLIES

MACHINE ROOM CABINET

Advantages of the GMV solutions:

  • Requires minimal space inside the machine room without compromising safety and convenience during maintenance works and hand operation in case of emergency.
  • Cost avoidance for masonry works of the machine room.
  • Drastically reduced installation times and wiring of the machine room
  • The elimination of the machine room means saving space for a different use

HEAT EXCHANGERS

The GMV heat exchangers are used on hydraulic systems when operational conditions or high traffic lead to an overheating of the fluid.

The small sizes allow the installation inside the machine room provided with an appropriate thermal outside exchange.

Through the heat balance calculations during the designing process of the elevator, it is possible to specify a maximal number of travels/p. hour, beyond which an oil cooling system as well as appropriate heat exchangers should be applied.

MOTOR PROTECTOR DEVICE SM 110

The electronic motor protector device SM 110 is designed to protect the motor stator windings from overheating damages.

The protector operates by direct temperature control of the engine through adequate thermistors inside the windings.

THE PAWL DEVICE

The “Pawl Device” is one of the safety devices required from the European standards for hydraulic elevators. The “Pawl Device” has two main functions:

to prevent the movement of the car in case of fluid leakage or changes of the fluid volume.
to stop the car and keep it stationary in case the piston supply piping should break.
The “Pawl Device” is equipped with a hydraulic buffer and guarantees a deceleration value lower than “gn” (9,81 m/s2), as an alternative to the traditional buffers on the pit ground.
