Abstract
A hydraulic cable puller that includes a hub having an axially-extending annular winding spindle for receiving a plurality of wraps of a rope adapted to connect to a downstream end of a cable to be pulled and to exert a pulling force on the cable. A hydraulic motor is mounted on the hub for rotating the hub and includes an inlet port and outlet port for being attached to inlet and outlet hydraulic supply conduits of a vehicle. A mounting bracket is adapted to mount the hub and the hydraulic motor onto an end of a boom arm of the vehicle.
Claims17
A hydraulic cable puller mounted on a boom arm of an excavator, comprising:
- (a) a hub having an axially-extending annular winding spindle for receiving a plurality of wraps of a rope adapted to connect to a downstream end of a cable to be pulled and to exert a pulling force on the cable;
- (b) a hydraulic motor mounted within a housing on the hub for rotating the hub and including an inlet port and outlet port for being attached to inlet and outlet hydraulic supply conduits of the excavator;
- (c) a mounting bracket adapted to mount the hub and the hydraulic motor onto a sidewall of a bucket attached to an end of a boom arm of the excavator;
- (d) the hub and hydraulic motor extend laterally outward from and within a plane of the sidewall exterior to the bucket;
- and
- (e) whereby an axis of rotation of the hub perpendicular to the side wall of the bucket is maintained during movement of the bucket on the boom arm of the excavator.

- (b) a hydraulic motor mounted within a housing on the hub for rotating the hub and including an inlet port and outlet port for being attached to inlet and outlet hydraulic supply conduits of the excavator;
- (c) a mounting bracket adapted to mount the hub and the hydraulic motor onto an exterior sidewall of a bucket attached to an end of the boom arm of the excavator, the mounting bracket having an upper hooked portion adapted to extend over an edge of the bucket sidewall and partially extend along an interior surface of the bucket sidewall to position and support the mounting bracket in a fixed location relative to the bucket;
- (d) the hub and hydraulic motor adapted to extend laterally outward from the exterior sidewall of the bucket within the plane of the bucket sidewall;
- and
- (e) whereby an axis of rotation of the hub perpendicular to the side wall of the bucket is maintained during movement of the bucket on the boom arm of the excavator.

- (c) a mounting bracket adapted to mount the hub and the hydraulic motor onto an exterior sidewall of a bucket attached to an end of the boom arm of the excavator, where the mounting bracket has a hooked portion adapted to extend over an edge of the bucket sidewall and partially extend along an interior surface of the bucket sidewall to support the mounting bracket at a fixed location relative to the position of the bucket;
- (d) the hub connected to an end of the housing opposite to the mounting bracket and extending laterally outward from the housing in a laterally outward direction from the plane of the bucket sidewall;
- (e) whereby an axis of rotation of the hub perpendicular to the side wall of the bucket is maintained during movement of the bucket on the boom arm of the excavator;
- and
- (f) a plurality of clamping knobs having threaded stems adapted to extend through the mounting bracket and cooperate with the sidewall further securing the mounting bracket to the sidewall.
