Hollow hydraulic lifting cylinder with oil return

Double acting hollow hydraulic lifting cylinder with oil return, designed for high-pressure applications such as cable tensioning, bar positioning, and assembly/disassembly work. Built for accurate, safe, and efficient operation in demanding industrial environments.

Hollow hydraulic lifting cylinder with oil return

Double acting hollow hydraulic lifting cylinder with oil return, featuring a central hollow passage for cable tensioning, tension bars, dywidag and macalloy applications. Designed for cable tensioning operations, pulley assembly and disassembly, hoisting, and pull testing.

The oil return system allows longer strokes than spring return cylinders and shorter return times under all operating conditions. The threaded body helps with easier, more accurate, and safer positioning, while the robust design includes a removable head, a stop ring for operator safety, and a wiper to reduce contamination.

This hydraulic lifting cylinder is also known as a hydraulic jack or lifting jack, used to raise and lift heavy loads.

Key Features

  • Hollow center: The hollow center allows cables and tension bars to pass through, making the cylinder ideal for tensioning, positioning, and assembly tasks.
  • Oil return: Oil return provides longer stroke capability than spring return cylinders, together with faster return times.
  • Threaded body: The threaded body makes it easier to secure the cylinder to structures or machinery and helps ensure precise positioning.
  • Safety and durability: The stop ring helps prevent plunger over-stroke and improves eccentric load absorption, while the removable high-strength head and wiper support long service life.
  • Applications: Suitable for cable tensioning, tension bars, pulley assembly and disassembly, hoisting, and pull tests in industrial and field use.
  • Handling: Models weighing more than 20 kg are equipped with a handle or lifting eyebolts for easier carrying.
