Abstract:
A metallic cable (10) comprises a strand of identical helical shaped filaments (11, 12, 13) positioned beside and against each other such that each filament of the strand is in line contact with at least one other filament of the strand. The helixes of the filaments of the strand are sloped in a first direction. A single filament (14) is twisted with the strand in a direction opposite to said first direction. An apparatus and a method for manufacturing the metallic cable are also disclosed.
Abstract:
Elevator, which includes at least an elevator car and a device for moving the elevator car, preferably along guide rails, and a counterweight, and one or more ropes, which rope connects the elevator car and the counterweight and is separate from the supporting function and passes around a diverting pulley mounted on the bottom end of the elevator hoistway. The rope comprises a power transmission part or a plurality of power transmission parts, for transmitting power in the longitudinal direction of the rope, which power transmission part is essentially fully of non-metallic material.
Abstract:
Elevator, which comprises at least an elevator car and means for moving the elevator car, preferably along guide rails, and an overspeed governor arrangement, which comprises an overspeed governor rope, which moves according to the movement of the elevator car, and which overspeed governor rope is connected to a brake arrangement that is in connection with the elevator car such that with the overspeed governor rope force can be transmitted to the brake arrangement for shifting the brake comprised in the brake arrangement into a braking position. The rope comprises a power transmission part or a plurality of power transmission parts, for transmitting force in the longitudinal direction of the rope, which power transmission part is essentially fully of non-metallic material.
Abstract:
A process for producing an eye at one or both ends of a coverbraided rope, the process comprising the steps of: a) providing a spacer; b) situating the spacer proximal a splice braid zone of an eye of the sling formed of the core rope; c) forming with a braiding machine a braided sheath about the splice braid zone to about the location where the splice braid zone meets its eye and covering at least portions of the spacer with at least a portion of the braided sheath; d) withdrawing from converging braid strands the eye having had its splice braid already covered by the braided sheath; e) forming with the braiding machine a length of hollow braided sheath; f) severing the length of hollow braided sheath; g) attaching to the spacer a severed end of the hollow braided sheath formed of the same strands that form at least a portion of the braided sheath and subsequently pulling the spacer out from between the braided sheath and the core rope in a direction that draws the severed end of the braided sheath into the braided sheath and causes it to occupy a position that previously was occupied by the spacer.
Abstract:
An elevator includes an elevator car, a counterweight and suspension roping, which connects the elevator car and counterweight to each other, and which suspension roping includes one or more ropes, which include a load-bearing composite part, which includes reinforcing fibers in a polymer matrix. The elevator car and the counterweight are arranged to be moved by exerting a vertical force on at least the elevator car or on the counterweight. The elevator includes a device separate from the suspension roping for exerting the force on at least the elevator car or on the counterweight.
