The Yale RPYS-1215 is a hydraulic test rig with maximum capacity of 12 tonnes, designed for testing pul-lifts, lever hoists, chain blocks, wire rope pullers and other lifting equipment after repair or inspection. Yale supplies the test rig complete and ready to use with a mounted HPS-2/0.7 A two-stage hand pump and YCS-21/150 hollow cylinder.
Workshop test rig for lifting equipment after repair or inspection
Yale documentation describes the test rig operation: 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, and the applied force is read on the pressure gauge. For brake testing, the hand pump may be used to apply a counter pressure and thus increase the pulling force after a general test. Yale notes that for frequent testing, the hand pump may be replaced by a low-cost air hydraulic (PAY-6) or electric pump (PY-04/2/5/2 M).
Suitable Applications
Per Yale: testing pul-lifts, lever hoists, chain blocks, wire rope pullers and other lifting equipment after repair or inspection. Includes testing of the hoist brake functionality.
Matched pumps, cylinders and accessories are needed to complete the circuit.

Frequently Asked Questions
Q: What can the RPYS test?
Yale specifies pul-lifts, lever hoists, chain blocks, wire rope pullers and other lifting equipment after repair or inspection.
Q: How does brake testing work?
Yale documents: 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.
Q: Can I replace the hand pump?
Yes. Yale notes that for frequent testing, the hand pump may be replaced by a low-cost air hydraulic pump (PAY-6) or electric pump (PY-04/2/5/2 M).
Q: Are pull-rings supplied for smaller items?
Yes. Yale specifies upper and lower hook suspension by shackles, including two 5 tonnes pull-rings for smaller test units.
Q: Can the lower suspension be removed?
Yes. Yale specifies the lower suspension is removable - e.g. for testing of plate clamps.
