Problems solved by technology

[0004] The problem with existing lifting solutions is that a significant reduction in friction between the coated rope and the sheave can lead to unintentional slipping of the rope along the sheave
In particular, if water or any other liquid, such as a substance containing oil or any other lubricant, is trapped between the rope and the traction sheave, it may cause a decrease in the frictional properties, which may lead to unintentional slipping

Embodiment Construction

[0020] figure 1 A preferred embodiment of an elevator is shown comprising an elevator car 1 and suspension ropes R suspending the elevator car 1 with at least one suspension rope 2, 2', 2" connected to the elevator car 1 , preferably a plurality of suspension ropes 2, 2', 2". figure 2 Figures a to 2c show alternative cross-sections of individual ropes 2, 2', 2". Each of the above-mentioned at least one suspension rope 2, 2', 2" comprises an elastomeric coating 4 (i.e. A layer 4 of one or more load-bearing members 3 , 3 ′, 3 ″ in elastomer), the coating 4 forms the outer surface of the rope 2 , 2 ′, 2 ″. Each of said at least one suspension rope 2, 2', 2" is engaged with a rotatable traction member 6 via said outer surface formed by coating 4. Coating 4 is in contact with rotatable traction member 6, in particular its Traction surface contact. The properties of the joint between the rotatable traction member 6 and the rope 2 , 2 ′, 2 ″, in particular the specific firmness of...

Abstract

The invention is related to an elevator comprising an elevator car (1) and a suspension roping (R) suspending the elevator car (1), the suspension roping (R) comprising at least one suspension rope (2, 2', 2") connected to the elevator car (1), wherein each of said at least one rope (2, 2', 2") comprises one or more load bearing members (3, 3', 3") embedded in an elastomeric coating (4) forming the outer surface of the rope (2, 2', 2"), and a rotatable traction member (6) engaging the outer surface of said at least one rope (2,2',2").The elevator further comprises means (M, 10) for rotating the rotatable traction member (6). The elastomeric coating (4) is made of microcellular elastomer whereby the rope (2, 2', 2") can receive excessive substance, such as water, and transport it away from the contact between the rope (2, 2', 2") and the rotatable traction member (6).

Description

technical field [0001] The present invention relates to an elevator, in particular to an elevator suitable for transporting passengers and / or goods. Background technique [0002] In elevators, such as so-called traction sheave elevators, the elevator car is usually suspended by suspension ropes consisting of a plurality of suspension ropes which span a rotatable traction member, usually in the form of a traction sheave. The traction sheave is generally driven by an electric motor under the control of a control system, whereby the upward or downward transport of the elevator car can be achieved in an automatic manner. The suspension ropes are usually frictionally engaged by a traction sheave. [0003] In the prior art there are cords which have one or more carriers coated with an elastomeric material. This is done for a variety of reasons. For example, the coating can be adjusted, generally aimed at increasing the power transmission capacity through the frictional engageme...
