Luffing cylinders are double-acting, utilizing hydraulic pressure for both extending and retracting the piston rod to provide full control over the boom’s position. They are engineered for high strength and durability, with robust designs capable of withstanding heavy loads and challenging environmental conditions. Many are equipped with advanced sealing configurations and high-strength materials to resist abrasion from dust and resist corrosion in harsh environments, including maritime applications. A key feature is their precision control, which ensures smooth, “stick-slip-free” movement for the accurate placement of loads.

They also often incorporate critical safety features, including relief valves to prevent overpressure and check valves to lock the boom securely in position when idle.

Customization options are available for various bore sizes, stroke lengths, and mounting styles to match specific crane designs and operational requirements.
