Abstract

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.

First claim

What is claimed is:

1. An elevator system comprising:
a hoistway;
an elevator car suspended in the hoistway via one or more suspension members;
a counterweight suspended in the hoistway via the one or more suspension members to balance operation of the elevator car;
a bedplate extending across the hoistway;
a machine disposed at the bedplate to drive the one or more suspension members along the hoistway, driving motion of the elevator car and/or counterweight along the hoistway, the machine including a machine frame secured to the bedplate;
a suspension member termination disposed at the machine frame, to secure an end of the one or more suspension members; wherein a termination body is formed integral to the machine frame, and a termination wedge inserted into the termination body to secure the one or more suspension members at the termination body.

2. The elevator system of claim 1 , wherein the machine is supportive of a counterweight end of the one or more suspension members, the counterweight end nearest the counterweight.

3. The elevator system of claim 1 , further comprising a termination opening in the machine frame, the suspension member termination extending through the termination opening.

4. The elevator system claim 1 , wherein the elevator car is disposed adjacent to the counterweight relative to a width of the hoistway.

5. A drive system for an elevator comprising:
one or more elevator suspension members;
a machine interactive with the one or more elevator suspension members to drive motion of an elevator car, the machine including a machine frame configured to be secured to bedplate;
a suspension member termination disposed at the machine frame, to secure an end of the one or more suspension members at the machine; wherein a termination body is formed integral to the machine frame, and a termination wedge inserted into the termination body to secure the one or more suspension members at the termination body.

6. The drive system of claim 5 , further comprising a termination opening in the machine frame, the suspension member termination extending through the termination opening.

7. The drive system of claim 5 , wherein the machine is supportive of a counterweight end of the one or more suspension members, the counterweight end nearest a counterweight of the elevator.

8. The drive system of claim 7 , wherein an elevator car is disposed in a hoistway adjacent to the counterweight relative to a width of the hoistway.
