According to one embodiment, a rope cleaning device comprises a scraper ring which engages grooves between strands of a wire rope to scrape out foreign material from the grooves as the wire rope passes through the scraper ring, a wiper ring positioned in series with the scraper ring for wiping the surface of the wire rope as the wire rope passes through the wiper ring and a rotational mechanism which allows the scraper ring to rotate about the axis of the wire rope.

A method of surface treating a load-bearing member comprising a tension member and a polymer jacket around the tension member is disclosed. According to the method, a liquid composition including water, a water-soluble organic polyol or a water-soluble organic polymer, and a surfactant is applied to a surface of the polymer jacket.

The present application relates to service tools and methods for servicing an elevator.

A method for retrieving a mobile platform from inside a tank having an energetic substance includes configuring a retrieval carrier to have an intermediate span for which a majority of a cross-sectional area includes a braided synthetic fiber rope having a porosity of at least ten percent and an elastic compressibility sufficient to reduce the porosity of the braided synthetic fiber rope by at least fifty percent. The intermediate span does not have a fluid tight passage enabling fluid communication between a location outside of the tank and the mobile platform. The method further includes configuring a retrieval assembly to have an energetic substance extractor that has opposing surfaces defining a passage, passing the intermediate span through the passage, and compressing the intermediate span between the opposing surfaces to extract a majority of the residue of the liquid energetic substance retained by the intermediate span upon entering the passage.

An elevator traction belt cleaning device and an elevator system. The elevator traction belt cleaning device includes: a set of slide rails installed to fixed positions in an elevator system; and a cleaning assembly having a cleaning opening for a traction belt to pass through, a sand removing member installed at the cleaning opening, and a set of slide blocks; in which the cleaning assembly is slidably installed between the set of slide rails through the set of slide blocks.
