Abstract: A portable crane assembly is disclosed including a support that can be selectively coupled to and decoupled from a transport dolly. The support includes a plurality of legs that can support a crane boom independently of the dolly. The transport assembly is used to transport the support and boom independently of other items that require movement such as a transformer.

Abstract: A remote control handle assembly for remote control of a powered dolly, with the control handle assembly including a handle mount which rotatably mounts a pair of handles. The powered dolly has a pair of spring-centered valves and a pair of mechanical push-pull cables extending between the handle mount and the valves, with a movable inner cable of each push-pull cable connected one to each of the handles. Rotation of one handle controls forward-reverse direction of travel of the powered dolly and the rotation of the other handle controls steering, with the rotational axes of the handles being structurally related whereby one handle counteracts the rotational torque of the other handle.

Abstract: A pole-setting apparatus for raising a pole from a horizontal position and setting it in a vertical position in a hole and having a boom assembly extended between a ground-engaging dolly and a cradle-support structure, with a cradle frame pivotally mounted between its ends to the cradle-support structure, a single binder member for holding a pole in association with the cradle frame throughout manipulation of the pole, a single hydraulic cylinder connected between the cradle-support structure and the cradle frame for causing relative movement therebetween, and a quick-connection structure for pivotally connecting the boom assembly to the ground-engaging dolly.
