IL LONGLOOD CLP Series Single Acting Lock Nut Pancake Hydraulic Cylinders are engineered for heavy-duty lifting and load-holding applications where installation space is extremely limited. Featuring an ultra-low profile, UN mechanical lock nut, e a 700 bar maximum operating pressure, these hydraulic cylinders provide exceptional lifting performance while ensuring maximum safety during extended load support.

Designed for industrial maintenance, bridge construction, heavy equipment installation, costruzione navale, minerario, and structural engineering, the CLP Series offers reliable operation, superior durability, and enhanced operator safety.

CLP Series Features

Ultra-Low Height Design

The pancake cylinder design minimizes collapsed height, allowing lifting operations in confined spaces where conventional hydraulic cylinders cannot be installed.

Mechanical Lock Nut for Safe Load Holding

The integrated lock nut provides positive mechanical support after lifting. Once the desired height is reached, the lock nut can be tightened to securely hold the load without depending solely on hydraulic pressure.

Single-Acting Hydraulic Operation

The piston extends hydraulically and retracts under load, resulting in a simple, reliable design with fewer moving parts and lower maintenance requirements.

High-Strength Alloy Steel Construction

Manufactured from premium alloy steel with precision machining and heat treatment for outstanding strength, durabilità, and long service life.

Integral Tilting Saddle

Every CLP Series cylinder includes a hardened tilting saddle with up to 5° of tilt, helping distribute the load evenly and reducing harmful side loading.

Built-In Stroke Limiter

An internal overflow port prevents piston over-extension, protecting the cylinder from accidental damage during operation.

Corrosion Protection

A durable industrial coating protects the cylinder against corrosion and wear. An optional synthetic coating is available for even greater corrosion resistance and smoother operation.

700 Bar Working Pressure

Designed for continuous operation at 700 sbarra (10,000 PSI), ensuring powerful lifting performance while maintaining compact dimensions.

Why Choose LONGLOOD CLP Series?

Maximum Safety

The mechanical lock nut safely supports heavy loads for extended periods without relying solely on hydraulic pressure.

Designed for Tight Spaces

Its ultra-low profile allows lifting where standard cylinders simply cannot fit.

Heavy-Duty Performance

Capacities ranging from 60 A 520 tonnellate cover a wide variety of industrial lifting applications.

Long Service Life

Premium materials, precision manufacturing, and high-quality seals ensure dependable performance with minimal maintenance.

Improved Load Stability

The integral tilting saddle minimizes side loading while improving contact with uneven surfaces.

Compatible with Standard Hydraulic Systems

Operates with most 700 bar hydraulic hand pumps, electric pumps, and air hydraulic pumps.

Linee guida sulla sicurezza

To maximize safety and cylinder life:

• Always position the cylinder on a solid, level lifting surface.
• Never use pancake cylinders on sand, mud, loose gravel, or unstable ground.
• Keep the load centered on the saddle.
• Never exceed the rated lifting capacity.
• Do not exceed the maximum operating pressure of 700 sbarra.
• Tighten the lock nut before performing maintenance or long-term load support.
• Inspect seals and hydraulic connections before each use.

Frequently Asked Questions (FAQs)

1. What is a lock nut hydraulic cylinder?

A lock nut hydraulic cylinder uses a threaded mechanical locking ring to safely support a lifted load after hydraulic pressure has been applied. This provides an additional level of safety for long-term load holding.

2. What is the advantage of a pancake hydraulic cylinder?

Pancake cylinders have an extremely low collapsed height, making them ideal for lifting heavy loads in confined spaces where conventional cylinders cannot fit.

3. Can the CLP Series hold a load for an extended period?

Yes. Once the load has been lifted, the mechanical lock nut can be tightened against the cylinder body to provide secure mechanical load holding during extended operations.

4. What hydraulic pump should be used?

The CLP Series is designed for use with any 700 sbarra (10,000 PSI) hydraulic pump, including hand pumps, electric pumps, air-driven pumps, and gasoline-powered hydraulic pumps.

5. Can these cylinders be used horizontally?

They can be used horizontally in certain applications, provided the cylinder is fully supported and the load is properly aligned. Side loading should always be minimized.

6. Why does the cylinder include a tilting saddle?

The integral tilting saddle automatically adjusts to slight angular misalignment (up to 5°), reducing side loading and improving load distribution.

7. Are these cylinders suitable for lifting applications?

Yes. They are widely used for heavy lifting, equipment installation, bridge maintenance, costruzione in acciaio, minerario, and industrial maintenance where limited clearance is a challenge.

8. Can the CLP Series be customized?

Yes. LONGLOOD can provide customized capacities, strokes, coatings, mounting options, and OEM branding for bulk orders.

9. What maintenance is recommended?

Regularly inspect seals, clean the cylinder after use, keep hydraulic oil clean, lubricate the lock nut threads, and store the cylinder in a dry environment when not in use.
