When selecting a hydraulic cylinder jack, you should consider the following factors:

1. Selection of Jack Tonnage

Determine the required tonnage for the job. After accounting for seal impedance loss and support impedance loss between the cylinder and piston, the actual force is typically 94% – 95% of the rated value. For continuous operation, it is recommended to choose a higher tonnage, usually calculated at 70% – 80% of the rated capacity.

2. Selection of Stroke Length

If space allows, choose a jack with a stroke longer than actually required. This improves the system’s expandability, reliability, and durability.

3. Selection of Type

Jacks are basically divided into two categories: Single-acting (spring return or load return) and Double-acting. In the TorcStark product range, CLL and DS models do not have a spring return function and can only be retracted by load or gravity.

4. Selection of Quantity

Determine if multiple jacks are required for synchronous operation. This is a critical factor for system design and safety.

5. Warnings and Precautions for Installation and Operation

Ensure the load is centered and the force direction is aligned with the jack’s axis.

Any eccentric load must stay within the jack’s technical specifications.

Install jacks by mounting flanges on the neck threads.

When connecting quick couplings, they must be fully engaged, threads tightened, and end faces flush.

Avoid over-extending the jack piston.

Strictly prohibit disconnecting the oil pump interface while the jack is under load.

Keep away from heat, fire, rain, seawater, and moisture.

Immediately inspect the unit if any oil leakage or seepage is detected.

Do not operate double-acting jacks if the pull-end pipe joint is completely blocked. If a jack equipped with self-sealing couplings suddenly stops, the most likely cause is a loose coupling blocking the oil circuit.

6. Non-standard and Special Jacks

TorcStark can customize non-standard jacks or hydraulic jacks exceeding 1,000 tons according to your requirements.

To do so, you need to provide the following technical parameters:

What is the required tonnage force?

What are the required stroke and body height?

Are all piston, neck, or base threads required?

What are the required frequency of use and operating conditions?
