LPL series low profile lock nut cylinders
Compact cylinders, single-acting with gravity return. Cylinders equipped with a safety nut that allows for mechanical load support, thus ensuring a safe working environment. Built-in tilt saddle allows for misalignment up to 5 degrees.
Enerpac hydraulic cylinders LPL series – low height cylinders with lock nut (700 bar)
Enerpac hydraulic cylinders LPL series (low height single-acting cylinders with lock nut and gravity return, eng. Enerpac Low Height Lock Nut Cylinders) are specialized power hydraulics devices designed for precise lifting and safe, mechanical supporting of extreme weights in places with very limited mounting space. The LPL series offers a capacity range from 60 to 500 metric tons (generating forces from 606 kN to 5114 kN) at a maximum operating pressure of 700 bar (70 MPa). The unique, low-profile design combined with a mechanical lock nut allows for failure-free permanent load positioning. Once the nut is tightened onto the threaded plunger, the entire load is taken up mechanically, allowing for complete pressure relief in the hydraulic system and safe work under the raised object. Made with advanced Summit technology with a nitrocarburized surface and a built-in tilt saddle, Enerpac LPL cylinders are an indispensable solution in infrastructure construction, bridge service, heavy machine leveling, and the shipbuilding industry.
Application and technical characteristics of Enerpac LPL series cylinders
Enerpac LPL low height hydraulic cylinders with lock nut were created for tasks where traditional high-tonnage cylinders do not fit due to minimum height. They allow for the execution of difficult lifting operations with minimal working clearance.
- Mechanical load lock (Lock Nut): A dedicated safety nut tightened to the body guarantees 100% safety of mechanical load support without the risk of the plunger dropping.
- Exceptionally low minimum height: Reduced overall body height (from 126 mm to 192 mm) allows the cylinder to be inserted into low technological gaps.
- Built-in tilt saddle (Tilt Saddle): The integrated tilt saddle allows for load misalignment up to 3°–5°, preventing point overloads and protecting the plunger rod.
- Resistance to side loads up to 5–10%: Composite bearings and nitrocarburized hardened surfaces show high resistance to diagonal side forces under full load.
- Stroke-limiting overflow port: An integrated overflow port prevents excessive plunger extension and protects against accidental push-out.
Why choose Enerpac LPL series cylinders at the HYDRON store?
As an authorized distributor of Enerpac solutions, the HYDRON store offers 100% original, brand new LPL series cylinders that meet rigorous industrial safety requirements. The use of Summit technology with an anti-corrosion coating guarantees smooth rotation of the lock nut even under extreme mechanical load. Instead of temporary wooden or steel cribbing, the LPL nut creates a rigid and secure support for the structure. To build a complete lifting set, we recommend choosing other compatible products from our offer, such as original Enerpac hydraulic tools and cylinders, efficient 700 bar hydraulic pumps with Venturi option, high-pressure hydraulic hoses and reliable 700 bar hydraulic quick-couplers.

Frequently Asked Questions (FAQ)
What are Enerpac LPL series low height cylinders used for?
LPL series cylinders are used for lifting and long-term mechanical supporting of very heavy loads (from 60 to 500 tons) in places with low mounting clearance, such as bridge spans or machine housings.
How does the lock nut work in LPL cylinders?
After lifting the load to the desired height, the threaded nut is tightened to the face of the cylinder body. It takes up the entire mechanical load, allowing for the release of oil pressure and safe work under the load.
Do LPL series cylinders require a stable base?
Yes. Like all ultra-flat high-capacity cylinders, the LPL series requires support on a flat, rigid, and stable surface. Using them on soft ground (dirt, sand) without steel plates can lead to cylinder damage.
How does the LPL series differ from the HCL series?
Both series have a mechanical lock nut, however, the LPL series is characterized by a much lower minimum height and shorter stroke (45–50 mm), making it ideal for the tightest technological gaps.
