Embodiment Construction

[0065] Maintenance devices according to the present disclosure include figure 1 Lubricant dispenser 1 presented in . The lubricant distributor 1 comprises a lubricant pan 3 intended to receive lubricant 10 . The tray has a rectangular bottom 32 and four straight side walls 31A, 31B projecting perpendicular to the bottom 32 from the edges of the bottom 32 . The side walls 31A, 31B and the bottom 32 form a lubricant container 10 having a volume for receiving lubricant 100 .

[0066] The volume of this container 10 depends on the type of elevator system the maintenance device is intended for: in elevator systems with a machine room the volume can be 300-500 cm 3 , and in an elevator system without a machine room, the volume can be as large as 500-7000cm 3 , due to the fact that the container 10 cannot be refilled or charged during maintenance operations in a configuration without a machine room.

[0067] The lubricant pan 3 may be made of stainless steel or other material sui...

Abstract

The invention concerns a maintenance arrangement and a method for lubricating elevator ropes (5). The arrangement has a lubricant distributor (1) comprising a lubricant pan (3) with side walls (31) and a bottom (32), and rollers (2A-C) for applying lubricant (100) onto the elevator ropes (5). The rollers include a pick-up roller (2A) and two transfer rollers (2B, 2C).In the method, the lubricant (100) is applied to the elevator ropes (5) by one or both of the transfer rollers (2B, 2C).

Description

technical field [0001] The present disclosure relates to a maintenance device and a maintenance method. In particular, the apparatus and method relate to the lubrication of elevator ropes in elevator systems with or without a machine room. Background technique [0002] In elevator systems, lubrication is required to prevent wear of the elevator ropes and arrangements through which the ropes travel during the movement of the elevator car and counterweights in the elevator system during use. Furthermore, lubrication is performed to prevent internal frictional abrasion as well as internal and external wear of the external wires of the elevator ropes. This is done to ensure safe, smooth and economical operation of the elevator system. [0003] To ensure that the maintenance goals mentioned above are properly met, the lubricant must be thin enough to penetrate into the rope, and must have a high enough film strength to properly protect the outer wire. The former requires a low...
