Glossary

Available car area:

Car area measured 1m from the floor without taking into account any potential support bars that may be occupied by the passengers or loads during lift operation.

Buffer:

Component acting as an elastic damper at terminal limits and comprising a fluid- or spring-based braking system (or other analogous device).

Car:

Part of the lift or goods lift that receives the passengers and/or goods to be transported.

Car frame:

Metal frame supporting the car or the counterweight, attached to the suspension elements. This frame can be an integral part of the car itself.

Clearance:

Spaces at the top and bottom of the shaft.

Control:

Blocking control:

Control enabling registering of a single order and stopping the registration of any other call or dispatch while a first order is underway.

Collective control:

Control enabling registering of certain call or dispatch orders at any time.

Selective control:

Control rationally combining the action of a set of at least two lifts. Selective control can be collective or not.

Counterweight:

Mobile component of the lift or goods lift moving along the vertical or slightly vertically inclined guides and comprising a heavy mass acting as a counterweight to that of the car and a part of its load.

Doors :

Door with permanent automatic locking system:

Door whose full closing is triggered without the supply of further energy as soon as the passenger or driver stops keeping the door open and whatever the position in which this action is stopped.

Mechanical door system:

Door whose opening and closing is triggered using an auxiliary mechanism.

Mechanical door system with automatic control:

Door whose movement is triggered by use of the normal control device without action by the driver or passenger.

Mechanical door system with controlled manual control:

Door whose movement is triggered by the driver or passengers via a handle or special buttons, with the driver or passengers maintaining permanent control at least on the door closing movement.

Automatic door:

Door whose opening and closing are controlled directly by the very displacement of the car.

Landing door:

Door in the shaft enabling access to the car from each floor.

Fire-resistant landing door:

Full landing door that slows the passage of smoke and whose degree of resistance to fire is indicated in the regulations governing it.

Drum:

Filleted cylinder on which the car's (and potentially the counterweight's) cables are wound and attached.

Winch:

Driving mechanism for the car's suspension cables or chains. It essentially comprises:

  • an engine and its coupling system,
  • a braking system,
  • a gear triggering either a power pulley, a drum or a pinion.

Duplex:

Pair of devices. Triplex, Quadruplex, etc. are used to define equipment fitted with 3 or 4 devices or more.

Gearless:

Designates a gearless machine. The traction pulley is directly fitted onto the motor output shaft. The main asset of this type of machine is that it enables very quick displacement of the car.

Goods lift:

Permanent lifting device serving pre-defined floors and comprising a car, whose dimensions and layout do not enable access to passengers. The lift moves at least partially along vertical guides, or guides whose vertical incline is below 15 degrees.

Guides:

Components ensuring the guiding of the car or counterweight frame, as applicable.

Instantaneous safety gear:

Safety gear whose setting on the guides is almost immediate.

Level:

Generic term designating basement, ground floor or entrance hall and floors.

Lift:

Permanent lifting device serving pre-defined floors and comprising a car, whose dimensions and layout enable access to passengers. The lift moves at least partially along vertical guides, or guides whose vertical incline is no more than 15 degrees.

Nominal speed:

Car speed for which the device was built and for which normal operation is guaranteed by the supplier.

Overspeed governor:

Component that, when above a pre-determined speed, orders the stop of the machine and, if necessary, also orders the setting of the safety gear.

Pit:

Part of the shaft located below the lowest level served by the car.

Rated load:

Load for which the device was built and for which normal operation is guaranteed by the supplier.

Safety gear:

Mechanical component whose action is to stop a car or counterweight and keep it stopped in the event of upwards or downwards overspeed or in the event of breakage of suspension devices.

Shaft:

Space in which the car and the counterweight (if applicable) move. This space is materially delimited by the bottom of the pit, the walls and the ceiling.

Slides:

Parts fixed onto the car or counterweight frame to ensure connection with the guides.

Travelling cable:

Several cabled electrical wires in a sheath and connecting the car to the fixed electric lines.

All these elements can be assembled on a frame.
