HOIST FOR RETRIEVING AND LIFTING LOADS |
摘要 |
A hoist for retrieving, lifting and positioning a light load of up to about 1000 lbs, is described. The hoist comprises a boom support column having an attaching lower end and a boom support upper end. The boom support upper end has a boom assembly connector and a transverse support surface. The boom assembly has a connecting support wall and a lower projecting connector for rotational connection with the boom assembly connector for maintaining the boom at an upward angular position. A releasable locking mechanism locks the boom at the upward angular position. A boom actuating brake arrests rotational displacement between the connecting support wall and the transverse support surface when the boom is at a substantially horizontal load retrieving position. A pulley is rotatably secured to an axle secured at a free end of the boom. The pulley is adapted to guide a cable thereon through a cable guide linkage to align and maintain the cable on the pulley. The pulley is supported on an axle which is connected to a lateral pivot support. |
