A height of getting up of elevator - is a distance for vertical lines between the levels of lower overhead landings (loadings) grounds.

A height of mine - is a distance for vertical lines from the floor of hollow mine to ceiling above a mine.

A height of overhead part of mine - is distance for vertical lines from the level of the overhead landing (load ground) to ceiling above a mine (ceiling of mine).

A hydraulic elevator - is an elevator in which electro-pumping gidrodrive of forward motion gives a booth to motion.

A machine apartment - is a separate apartment for placing of elevators' equipment.

A mine - is a space, in which a booth, counterbalance and device of booth moves. 

A reconstruction - is a change of kinematics chart of elevator, increases of carrying capacity or nominal speed, which are carried out after introduction of elevator to exploitation.

A sidewalk freight elevator - is a freight squeezing elevator the booth of which goes out from a mine.

A single management - is a control system by work of one elevator.

A width of booth - is a distance for horizontal lines between the internal surfaces of booths' walls, that it is measured parallell included in a booth.

Nowadays factories-producers offer the high-quality electric elevators of world class of high level of comfort, reliability and safety. Application in the elevators of modern components provides smooth motion of booth, reduction amount of refuses, noiseless work of elevators, and the wearproofness of materials is guaranteed by reliability and longevity of service of all mechanisms.
  The elevators equipped with an electromechanic have advantages for buildings with enhanceable intensity of motion.
An electro-drive can be twospeed and frequency adjusting of speed.
A twospeed drive does not need large power, and that is why consumes a bit energy. It is an optimum variant for housings buildings.
The feature of frequency drives is the use of highly technological microsystem which provides the smoothness of motion of elevator at an acceleration and braking. The passengers of such elevators are served considerably quick and comfort due to more smooth acceleration and braking. And the less using of electricity for the start of elevator allows to economize electric power. At the rates of movement of booth 1 m/s and anymore it is recommended to apply the frequency adjusting of power occasion of elevator, which will provide not only the smoothness of motion of booth but also high exactness of stops.
The drive of doors can have the frequency adjusting also .
Doors of elevators can be central or telescopic opening. Feature and attractiveness of doors of the telescopic opening is in possibility to shorten the width of mine, keeping the contain booth and, accordingly, to economize a building area .
Depending on a necessity, a booth can be passable, that is,to have two opposite entrances.
 It follows to foresee a machine apartment for electric elevators. It can be above the mine of elevator or directly near a mine. Some models of electric elevators can not have a machine apartment.
The most modern construction of winch with the vertical location of engine allows to decrease the amount of mechanical details, mobile knots and welding elements, that considerably improved vibro- and sound-proof descriptions of winch, and also promoted the term of exploitation. Due to the use of this small winch the sizes of machine apartment grew short. Possibility of programming is done a management more flexible. Application of small winch, technology production of which is based on the use of microprocessors, and also modern inspector, decide the task of economy of electric power and provide reliability of equipment during the long-term exploitation.
For the special order, it is possible assembling of the special device for automatic putting of booth on the nearest stop at the sudden disconnecting of tension.
