Assignee:

Otis Elevator Company - Farmington CT

International Classification:

B66B 1108

US Classification:

187254, 187250, 187261

Abstract:

A steering angle of an elevator sheave on a shaft is adjusted at installation and subsequently during maintenance by one of several embodiments. In one embodiment, a bolt with a jam nut is adjusted to position the shaft precisely. In another embodiment, a tee bracket is anchored to a hoistway wall, and a jack bolt with shims is used to adjust the vertical placement of the long beams that support the elevator car frame and therefore the shaft.

Assignee:

Otis Elevator Company - Farmington CT

International Classification:

F16B 2/14

F16G 11/04

US Classification:

403314, 24136 K, 24136 R, 24115 M, 187411

Abstract:

A device for securing an end on a load bearing member in an elevator system includes a socket portion and a wedge portion. The socket and wedge preferably are made from an extruded piece of metal or a formed piece of sheet metal material. A brace member secures the wedge within the socket portion to maintain the wedge, and the corresponding portion of the load bearing member in place within the socket portion. The preferred arrangement includes friction enhancing surfaces on the corresponding portions of the socket and the wedge to facilitate maintaining the load bearing member in place.

US Classification:

187266, 187250, 187251, 187401

Abstract:

An elevator system () includes an underslung car (). A plurality of load bearing members (-) are closer together behind the elevator car and spaced farther apart near a front of the elevator car (). A plurality of sheaves (-) are supported for vertical movement with the car and rotational movement relative to the car () such that the load bearing members (-) can be arranged in a 2:1 roping ratio and extend underneath the car (). A disclosed example includes sheaves (-) rotatable about sheave axes that are at oblique angles relative to corresponding edges of the elevator car ().

Appl. No.:

11/815694

Inventors:

Boris Traktovenko - Avon CT, US

Assignee:

Otis Elevator Company - Farmington CT

International Classification:

B66B 1/34

US Classification:

187391, 187277, 187289

Abstract:

An elevator machine () assembly useful in an elevator system () includes a motor frame () that supports a motor () for selectively rotating a motor shaft (). A brake () selectively applies a braking force to resist rotation of the motor shaft (). At least one load sensor () resists undesirable movement of the brake () and provides an indication of a load that results from applying the braking force. A disclosed example includes using a first resistive member () to resist movement of the brake () relative to the motor frame () when the load is below a threshold load and using a second resistive member () to resist movement when the load exceeds the threshold load.

International Classification:

B66B 11/08

US Classification:

187257, 187251, 187254

Abstract:

An elevator system () includes multiple elevator cars () within a hoistway (). Counterweights () are associated with the respective elevator cars () by load bearing members (). In some examples, different roping ratios are used for the load bearing members (). In some examples, the lengths of the load bearing members () are selected to allow contact between the counterweights () within the hoistway () and prevent contact between the elevator cars (). The difference in car and counterweight separation distances is greater than a stroke of a counterweight buffer plus an expected dynamic jump of the elevator cars. A disclosed example includes passages () through a portion of at least one of the elevator cars () for accommodating the load bearing member () of another elevator car () located beneath the elevator car () with the passages ().
