Abstract
A modular, prefabricated elevator includes column-like guide modules (10) extending between a foundation module (13) and a head module (2) and attached to a building by fastening modules (11), and an elevator car (5) that is connected by support cables (3) with counterweights (9) running in the guide modules (10). A stationary drive for the car (5) is in the form of one or two drive modules (12) combined with the head module (2) or with the foundation module (13) and integrated into the modular system in this manner. Through appropriate selection of the number of drive modules (12), the mode of suspension and the motor power, a wide range of use is covered with respect to conveying load and speed.

In an elevator of modular construction that is connectable with a building wall having shaft doors at floors, the modular elevator including a foundation module, a head module, a pair of column-like guide modules extending between the head module and the foundation module, and an elevator car travelling between the guide modules and being connected to counterweights which are guided by the guide modules, a drive for the elevator car comprising:
- a drive module adapted to be connected to one of a head module and a foundation module of a modular elevator, said drive module including a motor having a pair of outwardly departing drive shafts;
- a pair of drive pulleys each connected to and rotated by a respective one of said drive shafts;
- a support cable adapted to be connected to an elevator car travelling between guide modules extending between the head module and the drive module and engaging said drive pulley for moving the elevator car;
- and
- each of said drive shafts being enclosed by a protective tube with a shaft bearing, which is supported in one of the guide modules behind said drive pulley.
In a modular elevator that is connectable with a building wall having shaft doors at floors, the elevator including a foundation module, a head module, a pair of column-like guide modules extending between the head module and the foundation module, and an elevator car travelling between the guide modules and being connected to at least one counterweight which is guided by one of the guide modules, a drive for the elevator car comprising:
- at least one drive module adapted to be connected to one of a head module and a foundation module of a modular elevator having column-like guide modules extending between the head module and the foundation module, said drive module including at least one motor with at least one outwardly extending drive shaft, said drive shaft being enclosed by a protective tube with a shaft bearing, said shaft bearing being supported in one of the guide modules;
- at least one drive pulley connected to said drive shaft and rotated by said motor, said shaft bearing being supported behind said drive pulley;
- and
- a support cable connected to an elevator car and engaging said drive pulley for moving the elevator car travelling between the guide modules.
An elevator of modular construction that is connectable with a building wall having shaft doors at floors, the elevator comprising:
- a foundation module;
- a head module;
- a pair of column-like guide modules extending between said head module and said foundation module;
- an elevator car mounted for travel between said guide modules;
- at least one counterweight which is guided by one of said guide modules;
- at least one drive module connected to one of said head module and said foundation module;
- and
- at least one drive pulley connected to and driven by said drive module and engaging a support cable connected between said elevator car and said counterweight wherein said drive module includes at least one motor with at least one outwardly extending drive shaft with said drive pulley attached thereto, said drive shaft being enclosed by a protective tube with a shaft bearing, said shaft bearing being supported in said one guide module behind said drive pulley.
