Problems solved by technology

[0006] However, it has been found that the operator may move away from the control member while performing his / her task in the pit and at the same time away from the safety button located in the pit itself
In this case, improper use of the elevator may pose a danger to the operator who cannot be in a position that prevents the movement of the elevator itself

Embodiment Construction

[0016] With reference to the above-mentioned figures, the system according to the invention comprises control means 1 of an elevator (not shown) adapted to be positioned in the lower section or pit 2 of an elevator shaft 3 (or similar enclosure) ( Figure 4) inside. The control member 1 is a button panel of the type used by the operator whenever maintenance operations (periodical or temporary) are carried out on the elevator, and the control member 1 comprises buttons 5, (with double positive open circuit contacts) for driving the elevator. point of the corresponding cam type) the conventional switch 6 and the emergency button 7 whenever the elevator is driven by a third party for some reason and moves when performing maintenance operations, thereby endangering the safety of the operator present in the pit 2 , pressing the emergency button 7 immediately stops the movement of the elevator in the elevator shaft 3 .

[0017] In order to make these operators present in said pit sa...

Abstract

A safety system for the maintenance of an elevator or lift moving in a shaft, said safety system comprising control means of the elevator or said lift in said shaft, said control means comprising a control device, said The control means comprise a push button, said control member being positionable in a rest position whenever said control member is not in use and during normal use of the elevator or lift.

Description

technical field [0001] The subject of the invention is a safety system for elevator or hoist maintenance. Another subject of the invention is an elevator or lift equipped with such a safety system. Background technique [0002] As is known, elevators move within a shaft or enclosure, either of the masonry type or defined by visible guides positioned along the side of a building or structure or an interior part of the latter. Usually, the elevator is driven by a motor located on the upper section of the elevator itself (or "elevator car") or in a machine room on the top of the elevator shaft. [0003] The hoistway also includes a lower section, which is generally hollow and remote from the lower stopping position of the elevator within its own shaft or enclosure, referred to as the hoistway "pit". [0004] Corresponding to the lower section, or "pit" to simplify the description more comfortably, there are usually control means of the elevator and are used during regular rou...
