The Yale YH range comprises double-acting hydraulic cylinders with hydraulic return, designed for universal heavy-duty lifting and positioning. Capacities span 5 to 200 tonnes at 700 bar operating pressure with strokes from 30 to 500 mm. The double-acting design provides both pushing and pulling force, with hydraulic return enabling faster piston retraction than single-acting designs.
Designed for heavy-duty industrial lifting, positioning and pulling
Yale describes the YH range as extremely robust, designed for universal heavy-duty lifting and positioning as well as industrial production and assembly. The cylinders offer high pushing and pulling forces with a high piston retraction speed. Major application areas per Yale include bridge building and civil engineering, off-shore work, ship building, frame presses, stamping fixtures and other industrial applications requiring high pushing and pulling forces.
Suitable Applications
Per Yale: bridge building, civil engineering, off-shore work, ship building, frame presses and stamping fixtures. The pulling capacity (30-50% of push capacity) makes the YH suitable for extraction and tensioning as well as standard lifting. YH-200 models deliver 2000 kN push and 900 kN pull.

Frequently Asked Questions
Q: What's the pull capacity vs the push capacity?
Each YH model has a specific pull capacity, generally 30 to 50% of push capacity. YH-200 series delivers 2000 kN push and 900 kN pull; YH-100 series delivers 1000 kN push and 450 kN pull. Refer to the model specification for exact values.
Q: From which YH model are carrying handles fitted?
Yale fits a carrying handle from YH-30/200 model upward. Two lifting rings are fitted from YH-50/350 and larger.
Q: Why double bronze bearings?
Yale specifies long bronze piston guidings to withstand eccentric loading and extend service life under heavy industrial use. The piston is hard chromium-plated to run in the bronze bearings.
Q: What pump matches the YH range?
Yale's selection chart pairs YH cylinders with HPH double-acting hand pumps - HPH-2/0.7 A for smaller models scaling up to HPH-2/10 A for the largest.
Q: Are AYP threaded flanges available?
Yes. AYP-1510 fits YS-15 AND YH-10; AYP-2310 fits YS-23 AND YH-20; AYP-5010 fits YS-50 AND YH-50; AYP-10010 fits YS-100 AND YH-100; AYP-20010 fits YH-200.
Q: Are AYH clevis eye mountings available?
Yes - AYH clevis eye mountings are specifically designed for YH cylinders. AYH-5-1/2 for YH-5 series; AYH-10-1/2 for YH-10 series; AYH-20-1/2 for YH-20 series.
