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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) A hydraulic cable puller according to claim 1, wherein the annular winding spindle of the hub is positioned between first and second flanges. ### Claim 3 (depends on 1) A hydraulic cable puller according to claim 1, wherein the annular winding spindle of the hub includes a surface texture adapted to provide enhanced frictional resistance to slippage as the hub pulls the rope to which the cable is attached. ### Claim 4 (depends on 1) A hydraulic cable puller according to claim 1, wherein the mounting bracket is a plate connected to an exterior sidewall of the bucket, wherein the housing containing the motor is connected to and extending laterally outward from the plate within the plane of the bucket sidewall and the hub is connected to an end of the housing opposite to the plate. ### Claim 5 (depends on 4) A hydraulic cable puller according to claim 4, wherein the plate has a hooked portion for hanging over an edge of the bucket sidewall and partially extending along an interior surface of the bucket sidewall. ### Claim 6 (depends on 4) A hydraulic cable puller according to claim 4, wherein the plate is secured to the bucket sidewall with at least one bolt attached to the plate and passes through a hole in the bucket sidewall for positioning the plate on the bucket. ### Claim 7 (depends on 4) A hydraulic cable puller according to claim 4, wherein the plate is secured to the bucket with at least one clamping knob having a threaded stem. ### Claim 8 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 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. ### Claim 9 (depends on 8) A hydraulic cable puller according to claim 8, wherein the annular winding spindle of the hub is positioned between first and second flanges. ### Claim 10 (depends on 8) A hydraulic cable puller according to claim 8, wherein the annular winding spindle of the hub includes a surface texture adapted to provide enhanced frictional resistance to slippage as the hub pulls the rope to which the cable is attached. ### Claim 11 (canceled) ### Claim 12 (depends on 8) A hydraulic cable puller according to claim 8, wherein the plate is secured to the bucket sidewall with at least one bolt attached to the plate and passes through a hole in the bucket sidewall for positioning the plate on the bucket. ### Claim 13 (depends on 8) A hydraulic cable puller according to claim 8, wherein the mounting bracket is secured to the bucket with at least one clamping knob having a threaded stem. ### Claim 14 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 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. ### Claim 15 (depends on 14) A hydraulic cable puller according to claim 14, further comprising a bolt extending through the mounting bracket and the sidewall and cooperating with a nut on an inside of the sidewall for further securing the mounting bracket to the sidewall. ### Claim 16 (depends on 14) A hydraulic cable puller according to claim 14, wherein at least one of the plurality of clamping knobs is positioned on an outside of the sidewall. ### Claim 17 (depends on 14) A hydraulic cable puller according to claim 14, wherein at least one of the plurality of clamping knobs is positioned on an inside of the sidewall.
