Factory Direct Supply of Heavy Duty Hydraulic Jacks with Roller Burnished Cylinders

The hydraulic cylinder jack system combines a manual oil pump with a heavy-duty lifting jack, designed specifically for demanding industrial applications such as bridge deck lifting during pier reconstruction. This single-acting general purpose jack features a compact structure for convenient operation in various positions.

Key features include high strength alloy steel construction for exceptional durability, chrome plated piston rods that resist wear and corrosion, and integrated dust wipers to prevent contamination. The baked enamel finish provides additional corrosion resistance for long service life in harsh environments.

All cylinders undergo rigorous quality control, being proof tested to 125% of rated capacity before leaving the factory. The 10-100 ton models feature roller burnished cylinder bores that harden the surface while improving smoothness of operation. The series offers both spring return (0-200 ton) and load return (250-1000 ton) configurations to suit different application requirements.

Standard equipment includes HH-II 3/8" NPT male half couplers with protective dust caps and flat grooved saddles. Custom tilt saddles are available upon request for specialized lifting applications.
