Yale RPYS-1215 Banco di prova idraulico per apparecchiature di sollevamento

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 100 mm, Kl. 1.0 %%
Pressure gauge 2 for big test items: GGY-1003, display: 0 - 400 bar, Ø 100 mm, Kl. 1.0 %

AYP-1215-S Test plate for permanent load lifting magnets
Test load max. 12 t
For testing of permanent load lifting magnets according to DIN EN 13155
The plate is placed into the 12 ton test rig RPYS-1215 (or other versions of this test rig) and connected to the frame with a bolt.
The test plate with a standardised surface according to DIN EN 13155 kann be adjusted horizontally to align it steadily.
Dimensions: 800 x 490 x 60 mm
