Abstract: A cable puller in accordance with some example embodiments is configured to pull rope or cable through a conduit. The cable puller includes a puller frame having a first side and a second opposite side, first and second capstans rotatably mounted on the frame, and a motor operatively coupled to the first and second capstans and configured to rotate the first and second capstans. The first and second capstans extend outwardly from the same side of the frame.

Abstract: A handle for a hydraulically driven tool reduces the amount of heat transmitted to the user of the tool as a result of the high temperature fluid flowing through the inner body of the handle. The inner body is formed of a heat transmissive material which has at least one channel through which the fluid flows. The handle has a number of properties which reduces heat transmission to the user, including standoffs, ribs and fastener receiving extensions.

Abstract: An adapter is used to mount the cylinder to a fluid channel. The adapter is formed of a unitary wall including a first portion adapted to mount to the fluid channel, a second portion adapted to be engaged with a tool extending from the first portion, and a third portion extending from the second portion and seated within an inlet passageway of the cylinder. The third portion includes locking features for locking the adapter to the cylinder, and a sealing feature for sealing the adapter to the cylinder. The sealing feature is distal to the second portion such that when a torque is applied to the adapter, the sealing feature does not cause the adapter to shear. The cylinder and fluid channel may be capable of being swiveled relative to each other around the adapter, such swiveling may be up to 360 degrees and may be 360 degrees.

Abstract: A bypass assembly varies the hydraulic motor revolutions per minute (rpm) of a hydraulically driven tool, such as a wrench or a drill. This controls the torque of a driven mechanical mechanism, such as used on an impact wrench. The tool includes a body having a supply channel capable of being connected a source of fluid, a bypass spool channel in fluid communication with the supply channel, and a return channel in fluid communication with the bypass spool channel via a port and in fluid communication with the source. A bypass spool seats in the bypass spool channel. The bypass spool can be rotated to three discrete positions within the bypass spool channel to provide three different settings of revolutions per minute (rpm) of the gear motor.

Abstract: A relief valve assembly limits the maximum torque of a gear motor of a hydraulically driven tool. The relief valve assembly dumps flow to a return channel to return hydraulic fluid to the supply when the relief valve assembly is activated. The relief valve assembly is placed in the channel of a directional valve spool, and varies its pressure setting depending upon spool position. This is useful to vary the pressure settings of a hydraulic motor in different directions.
