Problems solved by technology

However, one problem when using paraffin is that when the rope gets hot, the oil film structure, in this case the oil bound by the paraffin, can easily separate from the rope
Another problem with paraffin-based lubricants is that the traction sheave-rope contact becomes slipperier at higher temperatures, due to which it can be difficult to achieve the values ​​required by elevator regulations for the coefficient of friction between traction sheave and rope
If the coefficient of friction is too low, the rope will slip on the traction sheave, which causes problems and can also be a safety risk

Embodiment Construction

[0018] figure 1 A schematic and simplified view of a typical traction sheave elevator is shown, comprising an elevator car 1 , a counterweight 2 and installed therebetween elevator ropes formed by elevator ropes 3 parallel to each other. The elevator ropes 3 are guided in grooves dimensioned for the elevator ropes 3 to pass over a traction sheave 4 rotated by the hoist of the elevator. As it rotates, the traction sheave 4 simultaneously moves the elevator car 1 and the counterweight 2 in upward and downward directions due to friction.

[0019] The rope force T exerted on the elevator rope 3 due to the difference between the counterweight 2 and the elevator car 1 plus the load in the elevator car at any given time CTW and T CAR There are different magnitudes on different sides of the traction sheave 4 . When the elevator car 1 contains less than half of the rated load, the counterweight is usually heavier than the elevator car 1 and the load. In this case, the rope force T ...

Abstract

The object of the invention is a traction sheave elevator and a rope (3) that contains metal as a load-bearing material, such as the suspension rope of an elevator, which rope comprises at least one or more strands (7) laid from metal wires (9) and which rope (3) is lubricated with a lubricant (8). Another object is the use of the aforementioned lubricant for lubricating the rope (3). The lubricant (8) comprises at least oil and thickener, which thickener in the lubricant (8) comprises at least 10% or more of the mass of the lubricant (8).

Description

technical field [0001] The object of the present invention is a metal rope as defined in the preamble of claim 1, an elevator provided with a metal rope as defined in the preamble of claim 7 and a metal rope for lubricants as defined in the preamble of claim 11 For the purpose of lubricating metal ropes. Background technique [0002] Wire braided ropes of elevators or other lifting equipment, more particularly hoisting ropes, ie slings, are usually lubricated with some suitable lubricant. Lubrication improves the handling of the rope and reduces wear on the rope, in which case the service life of the rope is increased. Lubrication also prevents rusting of the rope. Ropes are usually lubricated in connection with rope manufacture, for example so that when weaving strands of the rope from steel wires, lubricant is sprayed into the strands to be manufactured. [0003] According to one prior art method, the lubricant used is based on paraffin. However, one problem when using...
