Hollow hydraulic lifting cylinder with spring return

Hollow hydraulic lifting cylinder with spring return

The CRM-FO Series includes hollow, single-acting hydraulic lifting cylinders with spring return, designed for high-pressure work at 700 bar. They are suitable for high pushing forces and a wide stroke range.

This model is intended for cable tensioning, tensioning bars, Dywidag bar and Macalloy bar applications, and can also be used as a hydraulic extractor. The hollow design allows a bar or cable to pass through the cylinder.

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

Key Features

• Hollow design: A high-strength hollow plunger cylinder for tensioning and hydraulic extraction applications.
• Spring return: Single-acting cylinder with spring return for efficient and convenient operation.
• Enhanced safety: The stop ring prevents piston over-stroke and improves operator safety, including better absorption of eccentric loads.
• Clean operation: The wiper reduces contamination between the ring and rod, helping maintain reliability.
• Removable head and mounting base: High-strength splined removable head and a base with threaded holes for securing the cylinder in any position.
• Custom solutions: Custom-made high-pressure hydraulic cylinders can be manufactured on request.
