100-ST155 Hatch Cover Hydraulic Jack

Core Functions and Applications
Powered by hydraulic pressure, marine hatch cover hydraulic jacks extend and retract plungers or pistons to provide steady support and lifting force for side-rolling and folding hatch covers. These jacks are critical parts for hatch covers manufactured by brands such as TTS and MacGregor, and are extensively applied in hatch cover systems across different types of ships to guarantee reliable operation.

Product Detail

PRODUCT ADVANTAGES​
  • High Durability: Cylinders are made from 45# seamless steel processed with precision, and their piston rods feature a chrome plating layer (0.05-0.1mm thick). This boosts wear resistance by 50%, making the jacks suitable for the complex working conditions at sea.​
  • OEM-Level Fit: Manufactured to fully match the specifications of the original vessel’s cylinders. The seals share the same dimensions and brand as the original parts, enabling a 1:1 performance replication that allows direct replacement without modifications.​
  • Rapid Delivery: In-stock models are dispatched within 24 hours after ordering; for urgent needs, air freight from Shanghai Port ensures delivery to major global ports in 3-5 days, meeting emergency repair requirements.​
  • All-Round Service: Beyond regular maintenance guidance, we offer an integrated repair service covering sandblasting, seal replacement, and pressure testing—streamlining customers’ maintenance workflows.
