ABSTRACT:
A self-contained portable test stand for testing hoists and the like both statically and dynamically. The test stand includes a cantilever beam adapted to support a hoist at one end and a hydraulic cylinder at the other. A variable mechanical advantage force transmitting means which may include a chain and chain block is provided to interconnect the hoist and the cylinder. The hydraulic loading of the cylinder is regulated both by a variable relief valve and a variable pressure and flow hydraulic pump which is controlled by a feedback line responsive to the pressure and flow in the system.
