Problems solved by technology

This severe excess travel requires the drive to generate substantially greater current and the motor to draw substantially greater current than during normal operation, which greatly reduces the life of these two electrical components

Embodiment Construction

[0033] figure 1 An exemplary embodiment of the arrangement of components within a typical high-rise elevator installation 1 is shown. The elevator drive 8 , the deflection wheels 14 and the elevator controller 16 are arranged in the machine room above the hoistway 3 . Inside the hoistway 3 the elevator car 2 and the counterweight 4 are supported on suspension ropes 6 . In this example the suspension ropes 6 have a rope ratio of 1:1 so that they extend upwards in the hoistway 3 from the end connections fixed to the car 2 to be rotated by the motor 10 of the elevator drive 8 through a wrap angle α The traction wheel 12 engages, then engages over the deflection wheel 14 and returns down the hoistway 3 to the other end connection fixed to the counterweight 4 . Naturally, the skilled person will readily understand that other rope arrangements, such as 2:1, 4:1 or x:1 rope ratios are equally possible, and that the invention can also be implemented by elevators using belts instead ...

Abstract

An elevator installation (1) and a method for temporary transportation of an overload within the elevator installation (1) wherein a car (2) and a counterweight (4) are interconnected by one or more suspension ropes (6) engaging a traction sheave (12) which is driven by a motor (10) and the traction between the suspension ropes (6) and the traction sheave (12) is enhanced independently of the counterweight (4) for intended overload operation.

Description

technical field [0001] The present invention relates to an elevator and a method of temporarily operating an elevator outside normal rated operating conditions to enable transport of heavy overloaded loads from one floor to another. Background technique [0002] In order to maximize installation efficiency while maintaining cost effectiveness, elevators are typically designed and manufactured to operate at predetermined rated operating conditions (eg, rated load and speed) to meet the transportation requirements specified by the particular equipment. [0003] However, there are temporary and uncommon situations where it would be useful to enable building owners to operate elevators outside of rated operating conditions, for example, for transporting heavy items, such as power transformers, which would otherwise be Items can overload the elevator. [0004] Typically, a solution has been used in which the mass of the counterweight is increased in proportion to the expected ov...
