Hydraulic test rig for hoisting equipment RPYS RPYS-1215 Capacity 12 t from Yale

Details

For testing pul-lifts, lever hoists, chain blocks, wire rope pullers as well as other lifting equipment after repair or inspection.

Testing of hoisting equipment
The lifting unit is placed between upper and lower shackle, the chain is tensioned against the oil cushion of the partly advanced piston of the hydraulic cylinder. The applied force can be read at the pressure gauge.

Testing of the hoist brake
For a functional test of the hoist brake the hand pump may be used to apply a counter pressure and thus increase the pulling force after a general test.

Frequent use
For frequent testing, the hand pump may be replaced by a low-cost air hydraulic (model PAY-6) or electric pump (model PY-04/2/5/2 M).

Pressure gauge
To read pulling forces more easily, the test rig is equipped with two high-quality pressure gauges. Quick couplers allow an easy replacement of pressure gauges. Pressure gauge 1 for small test items: GGY-1005, display: 0 - 160 bar, Ø 100mm, Kl. 1.0%
Pressure gauge 2 for big test items: GGY-1003, display: 0 - 400 bar, Ø 100mm, Kl. 1.0%
