Abstract:
An elevator includes a car, a counterweight, a suspension working together with the car and the counterweight, and a wheel at least partially wound around by the suspension. The suspension includes a tie beam arrangement with two tie beams and an encasing shell wherein a ratio of the width of the suspension to the height thereof is in a range between one and three. The wheel includes a flute having a flat base for guiding the suspension. When the suspension is unloaded, there is an air gap between the suspension and a guide region of the flute. The suspension is ovalized under loading to close the air gap. The shell is coated, at least in areas, on the outer surface thereof, wherein the coating optionally has a friction-reducing, friction-increasing, and/or wear-detecting effect.
Abstract:
A supporting and drive belt including a belt body or sheathing which encloses tensile carriers. The running surface of the belt can be flat and parallel to the belt back or have trapezium-shaped or semicircular ribs and grooves, wherein the profile of a drive pulley or of a deflecting pulley is approximately complementary to the running surface of the belt. One or more tensile carriers are provided for each rib, wherein the tensile carriers are laid or stranded alternately in the “Z” direction and the “S” direction.
Abstract:
A load bearing member for supporting an elevator car has a plurality of tension members that bear the weight of the elevator car. The plurality of tension members extends along a length. An outer cover at least partially covers the plurality of tension members and has a first surface and a second surface.
Abstract:
A load bearing member (34) for supporting an elevator car (10) has a plurality of tension members (38) that bear the weight and counterweight of the elevator car (10). The plurality of tension members extends along a length. An outer cover (42) envelopes the plurality of tension members and has a first surface and a second surface. The plurality of tension members are sandwiched between the first surface (46) and the second surf ace (48). The first surface is for traction on a sheave (22). The first surface and the second surface define a cross-section (52) transverse to the length of the load bearing member. The cross-section has a first end portion (56), a middle portion (60) and a second end portion (64). The middle portion has a first width (w1) between the first surface and the second surface which is smaller than a second width (w2) between the first surface and the second surface of one of the first end portion and the second end portion.
Abstract:
A method for forming a helix rope for a trawl comprising the steps of: a) situating upon a portion of a rope a bead of a substance being selected from a group consisting of: (i) a liquid substance; and (ii) a semi-liquid substance. A helix rope (35) for forming portions of a pelagic trawl, the helix rope comprising a braided sheath (398) formed of greater than sixteen strands (397), whereby drag is reduced. A method for forming a high strength synthetic rope useful for towing warps, trawler warps, yachting ropes, mooring lines, anchoring lines, oil derrick anchoring lines, seismic lines, paravane lines, and any other uses for rope, cable or chain.

Abstract:
An elevator belt for an elevator installation includes a belt body in which a tensile carrier arrangement with several tensile carriers for transmission of a tension force in a longitudinal direction of the elevator belt is arranged. A profile body which spaces these tensile carriers from one another is arranged between adjacent tensile carriers of the tensile carrier arrangement.

Abstract:
A rope includes two groups of yarn wires which are respectively coated by a coating made of PUC foam plastic. The coatings are arranged in parallel with each other and connected by a connection portion. The coatings can be dyed as different colors. Two or more ropes can be woven together to be a reinforced rope when necessary.
Abstract:
In a textile lifting sling or in a lashing strap thickened locations are provided at least on one side (7) of the sling in the longitudinal direction (2) of the sling so as project in the manner of longitudinal beads (6) or rows of nubs (9) beyond the outer surface (7) of the basic fabric of the webbing strap (5) or of the tube (4) so as to increase abrasion resistance.
