Controlled translation method of affixing a termination to a multi-stranded tensile member
A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. During the solidification process tension is applied. The resulting linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.

Elevator system suspension member termination
An elevator system includes a hoistway and an elevator car suspended in the hoistway via one or more suspension members. A counterweight is suspended in the hoistway via the one or more suspension members to balance operation of the elevator car. A machine is positioned at the hoistway to drive the one or more suspension members along the hoistway, driving motion of the elevator car and/or counterweight along the hoistway. A suspension member termination is supported at the machine, to secure an end of the one or more suspension members. A drive system for an elevator includes one or more elevator suspension members and a machine interactive with the one or more elevator suspension members to drive motion of an elevator car. A suspension member termination is supported at the machine to secure an end of the one or more suspension members at the machine.

Elevator system suspension member termination with improved pressure distribution
A termination device for a suspension member of an elevator system includes a housing, and a wedge assembly positioned in the housing. The wedge assembly is interactive with the suspension member to apply a clamping force to the suspension member in response to an axial load acting on the suspension member. The wedge assembly includes a compressible cushion configured to increase uniformity of the clamping force applied to the suspension member by the wedge assembly. An elevator system includes a hoistway, an elevator car located in the hoistway, a suspension member operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway, and a termination device located in the hoistway and operably connected to a suspension member end of the suspension member.

Counterweight for elevator system
A counterweight is provided including a counterweight frame including a crosshead. A counterweight hitch is operably coupled to the counterweight frame. The counterweight hitch includes a vertically stacked first sheave channel and a second sheave channel. Each of the first sheave channel and second sheave channel includes an interior cavity within which at least one individual sheave assembly is mounted. The plurality of individual sheave assemblies is substantially identical and arranged at an angle relative to a central plane of the counterweight frame.
Rope lifting tool and a rope lifting arrangement
A rope lifting tool for belt-shaped ropes provided with an uneven surface pattern on one or both of its opposing wide sides, includes a first guide for guiding the rope lifting tool along a first guide rail; a second guide for guiding the rope lifting tool along a second guide rail; an upright plate, and an inclined plate at an acute angle relative to the upright plate, the upright plate and the inclined plate having a wedge shaped space between them; and a plurality of wedge members placed adjacent each other inside the wedge-shaped space. A rope gap for receiving an end of a belt-shaped rope is formed between each wedge member and the upright plate, which rope gap is narrowable by wedging of the wedge member in the wedge shaped space. A rope lifting arrangement includes the rope lifting tool. Each rope gap is delimited by a vertical face of a wedge member and a vertical face of the upright plate or a vertical face of a liner attached thereon, and the vertical face of the wedge member and/or the vertical face of the liner is provided with an uneven surface pattern forming a counterpart for the uneven surface pattern of the belt-shaped rope.
Elevator termination assembly that provides an indication of elevator car load
An illustrative example assembly for determining a load on an elevator car includes a plurality of terminations respectively configured for securing an end of a load bearing member. A plurality of strain gages are respectively secured to a portion of respective ones of the plurality of terminations so that each of the terminations includes at least one of the strain gages. A load determining processor receives indications from the plurality of strain gages and determines a load on the elevator car based on the received indications.
