<p>The movable hydraulic power unit is used with light band tools (12) such as breakers and drills, providing hydraulic drive. The units uses an IC-engine (4) to drive a hydraulic pump (5) connected by pipe lines to a reservoir (6) and a distributor (8). Cooling may be by a fan (7) mounted on a chassis (1) equipped with a stabilizer (3) and road wheels (2). Controls incorporated in the distributor may be used to open and close a circuit (10,11) feeding the tool.</p> |
