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 a control member 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 (regular or temporary) are carried out on the elevator, and the control member 1 comprises push buttons 5, (with double positive open circuit contacts) for driving the elevator. point of the corresponding cam type) conventional switch 6 and emergency button 7, whenever the elevator is driven by a third party for some reason and moves during maintenance operations, thereby endangering the safety of the operator present in the pit 2 , press the emergency button 7 to stop the movement of the elevator in the shaft 3 immediately.

[0017] In order to make these operators present in said pit safer, a system accordi...

Abstract

A safety system for maintenance of a lift or elevator, the latter moving within a shaft or containment structure (3), said system comprising, in correspondence with a lower section (2) or, if hollow,pit of such shaft (3), a control member (1) of the lift within said shaft, said member (1) comprising control means (5) for controlling the movements of the lift along such shaft or structure (3) fromits lower section (2) during lift maintenance, said control means (5) comprising push-buttons, said control member (1) being positionable in a rest station whenever it is not used and during the normal use of the lift. The system according to the invention comprises position detector means (13) associated at least with the rest station and co-operating with said control member (1) whenever it islocated in such station, said position detector means (13) disabling the use of the lift by users whenever said control member (1) is separated from such station, this ensuring that the movement of the lift can only be made by operating the control means (5) of such control member (1). A lift equipped with such safety device is also claimed.

Description

technical field [0001] The subject of the invention is a safety system for elevator or hoist maintenance according to the preambles of the main claims. Another subject of the invention is an elevator or lift equipped with such a device and according to the preamble of the main claim. 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 comfo...
