Door lock: Is every type of mechanical lock, which is constructed to block the opening of the door of the elevator, when the cabin is not at the specific floor.
Down acting: Electrically controlled valve placed in a hydraulic circuit to check the descent of the cabin.
Drum elevator: Elevator with suspension chains or cables, that get carried away with any other means apart from friction.
Elevator of direct effects: Hydraulic elevator of which the piston or the cylinder are connected directly with the cabin or its casing with suspension means (cableway, chains).
Elevator of loads with people’s escort: Elevator that is destined mostly for transferring loads and there is generally people’s escort.
Elevator of small loads: Permanently installed lifting device that serves certain levels and has a cabin, which thanks to the procedures and its construction, is obviously accessible to people and moves, even partly, along vertical cursors with a slope less than 15o to the vertical.
Electric safety chain: The total of electric safety provisions, which are connected in a row.
Elevator with chain: Elevator with suspension chains or cables, that get carried away with any other means apart from friction.
Escalator: Is an electrical stairs, which automatically moves its steps and is used to transfer passengers.
Flexible cable: Is a flexible cable constructed from electrical conduits, which assures electrical supply between the cabin of every elevator type (passenger, loads etc.) and the devices that are either at the shaft or at the machine room.
Full load pressure: Static pressure which acts at the tubing, that are directly attached with the jack, when the cabin with its nominal load is stopped at its highest stop.
Guide rails: It is section merchant bar T-shaped, which is vertically put in the shaft to lead and guide the ride of the cabin of the elevator and counterweights.
Handrail: Is the moving part on the upper part of the rail of the escalator that is used from the passengers as a grip and moves along with the steps towards the same direction.
Headroom: Part of the shaft of the higher level which is served from the cabin and the roof of the shaft.
Hedging weight: Mass that saves energy, hedging all or a part of the mass of the cabin.
Hydraulic elevator: Elevator in which the necessary energy for lifting the load comes from an electrically motored pump. The pump transfers the hydraulic liquid in a jack that acts directly or indirectly to the cabin (more than one electric motors, pumps or / and lifting units can be used).
Hydraulic lift: Lift on which the necessary energy for lifting the load comes from an electrically motored pump. The pump transfers oil in a jack that acts directly or indirectly to the cabin (more than one electric motors, pumps or / and jacks can be used).
Impactor: Elastically suppressed element at the end of the ride, that includes a braking system with liquid or spring (or other relevant means).
Instantaneous safety gear: Grip device that acts almost instantly on the cursors.
Instantaneous safety gear with buffered effect: Grip device, that acts almost instantly on the cursors, in which the force reaction on the cabin or the counterweight is limited with the intervention of a damping system.
Jack: Combination of a piston and a cylinder that form a hydraulic unit.
Laminated glass: Total of two or more glass layers, each of which is attached with the rest with the use of plastic membrane.

Leveling: Process with which the parking accuracy of the cabin at the level of the stop is improved. It is the automatic move that the elevator does towards the level of the strorey at which it shifts when it is about to stop.
Lift: Permanently installed lifting device that helps definite levels and has a cabin which thanks to the processes and its construction is obviously accessible to people. The cabin moves, even partly, along vertical cursors with a slope less than 15 degrees to the vertical.
Lift machine: The total of the organs that assure the movement and the stop of the elevator, which consists of the pump, its motor and the handling valves.
Machine room: Is the place in which is the machinery, that set and control the secure and correct function of elevators and escalators
Minimum breaking load of a rope: The product of the square of the nominal diameter of the cable (in square millimeter) and a factor that depends on the constructional type of the cable.
Non return valve: Valve that allows the free flow in one direction.
One-way restrictor: Valve that allows the free flow in one direction, whereas it restricts it to the opposite direction.
Over-speed governor: Device that stops electric current at the motoring mechanism and if necessary, it switches the gripping device, in case that a specific speed is exceeded.
Passenger: Every person transferred from an elevator inside the cabin.
Pawl device: Mechanical device which stops the unintentional descent of the cabin and keeps it stopped in steady brackets.
Pit: the part of the shaft that lies under the floor of the last lower stop, which is served from the cabin.
Pressure relief valve: Device that limits the pressure in a specific price allowing the liquid to flow.
Progressive safety gear: Grip device of which the energy is achieved by breaking on the guide rails and with special means, the powers that act on the cabin, the counterweight or the hedging weight, are assured to be restricted within the permitted limits.
Pulley room: Area which includes the motoring mechanism and in which pulleys are, and possibly over-speed governor and electric devices.
Railing: It is about the left and right side of the escalator / corridor (glass or stainless) on which the door handle is applied.
Rated load: The load for which the equipment is constructed.
Rated speed: The speed of the cabin in meters per second for which the equipment is constructed.
Restrictor: Valve in which the openings of entrance and exit are connected with a limited passage orifice.
Re-leveling: Function that allows, after the stop of the elevator, the correction of the stop position during loading and unloading, if it is necessary and with successive movements.
Rupture valve: Valve designed to close automatically when the fall of the pressure in the valve, which is owed to the increase of the supply in a specific flow direction of the liquid, exceeds a certain rate.
Safety gear: Mechanical device that is used to stop and maintain still the cabin on the guide rails, the counterweight or hedging weight, in case of descent speed excess or breach of their suspension means.
Safety rope: Auxiliary cable tied on the cabin, the counterweight or the hedging weight, that is destined to activate a griping device, in case of miss of the suspension.
“Shut-off” valve: Manual valve with two orifices, which may allow or block the flow of the liquid in both directions.
Sling: Sling that the cabin has, the counterweight or the hedging weight, and is connected with the suspension means. This sling can be attached with the shell of the cabin.
Technical Features: Is the analytic description of the designs, materials, dimensions and all the rest elements that are required to supply and install elevators, escalators and corridors.
Traveling cable: Flexible cable between the cabin and a fixed point.
Unlocking zone: Area above and below the level of the stop of an elevator, in which the floor of the cabin must be, so that the release of the corresponding door of the shaft is allowed.
User: Person that uses the services of an elevator installation.
Well: Is the part of the building that is intended to put an elevator. The bottom is included to the well. The construction of the well also defines the installation of machinery at the right place.
