HCL Series High Tonnage Hydraulic Cylinders feature a lock nut to provide secure mechanical load holding for extended periods. These single-acting load return cylinders contain fewer parts than other types making them simple to use and maintain.
All Enerpac High-Tonnage Cylinders are equipped with numerous special features to ensure the durability, safety, and performance needed for large-scale construction projects. Among these features are low-wear high-pressure seals, replaceable composite plunger support bearings, and a robust nitrocarburized finish on the body, lock nut and plunger.

The Enerpac HCL502 is a 50-ton, single-acting, high-tonnage hydraulic cylinder designed for heavy lifting, load stabilization, and secure mechanical load holding. With a compact 1.97-inch stroke and an integrated safety lock nut, this model is ideal for applications where loads must remain supported for extended periods without relying on hydraulic pressure. Built to Enerpac’s industrial standards, the HCL502 combines strength, precision, and safety in a compact footprint suitable for demanding work environments.
Delivers 50 tons of lifting force, making it suitable for structural lifts, equipment jacking, and heavy industrial applications.
The lock nut allows the cylinder to securely hold the load mechanically, eliminating the need for continuous hydraulic pressure — a major safety benefit for long-duration lifts.
The 1.97 in stroke supports precision lifting, leveling, and alignment tasks where limited height adjustment is required.
Once pressure is released, the plunger retracts automatically for faster setup, simplified operation, and improved workflow efficiency.
A hard-chromed plunger and high-strength alloy body ensure resistance to wear, corrosion, and scoring, even under heavy industrial usage.
Enhances stability and reduces the risk of load movement during lifting operations.
Short stroke: Only 1.97 in of travel — designed for precise lifting rather than large vertical displacement.
Single-acting design: Retraction is spring-powered, not hydraulic; suitable for most lifting but slower than double-acting cylinders.
Requires a 10,000 psi compatible pump and hoses: Must match Enerpac system requirements for full rated performance.
Mechanical lock nut must be fully engaged: Critical for safe load holding; always verify proper engagement before working beneath a load.

The HCL502 is especially valuable in infrastructure, construction, and plant maintenance environments where load security and precision are essential.
Center hole cylinders feature a hollow bore that allows force to be applied through threaded rods or cables, enabling pulling and tensioning applications that standard cylinders cannot perform.
Center hole cylinders are commonly used for pulling, tensioning, and detensioning applications when properly configured with threaded adapters and reaction fixtures.
Center hole cylinder rentals provide access to specialized equipment for project-specific needs without the cost, storage, or maintenance requirements of ownership.
Center hole cylinders can apply pushing force, but they are most commonly selected for tensioning and pulling operations where centerline force application is required.
