Abstract: Portable, hand held, battery operated, hydraulic tools are provided with a tool frame and one or more interchangeable working heads. When the working head is connected with the tool frame, a piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task. The tool includes a sensor for detecting the type of head connected with the tool and a mechanism for adjusting the amount of force applied to the head by the hydraulic system based on the detected head type.

Abstract: A tiltable loading ramp for loading and unloading a first vehicle onto and from a second vehicle, comprises at least two ramp sections which are abuttable or substantially abuttable to form a ramp surface, and at least one support member forming a fulcrum for the ramp surface. The in use at least one support member is provided partway between ends of the ramp surface and spaces the ramp surface away from a loading surface of the second vehicle, so that as the first vehicle passes the fulcrum, the ramp surface tilts towards the loading surface of the second vehicle.
