De LONGLOOD RACL Series Single Acting Aluminum Lock Nut Hydraulic Cylinders combine the lightweight advantages of aluminum construction with the safety of a mekanisk låsemøtrik for secure, long-term load holding. Designed for demanding lifting applications, these cylinders provide outstanding portability, high lifting capacity, og øget operatørsikkerhed.
With lifting capacities from 20 til 150 tonsvis, strokes from 50 til 250 mm, og en maximum operating pressure of 700 bar (10,000 PSI), the RACL Series is ideal for bridge construction, vedligeholdelse af tungt udstyr, structural lifting, synchronized lifting systems, offshore engineering, minedrift, and industrial plant maintenance.
The integrated lock nut mechanically supports the load after lifting, eliminating reliance on hydraulic pressure alone and providing a safer solution for applications requiring extended load holding.
Manufactured from high-strength aerospace-grade aluminum alloy, the RACL Series is significantly lighter than comparable steel cylinders, making transportation, installation, and positioning easier.
Each cylinder features a precision-machined lock nut that provides positive mechanical load support after lifting. This ensures safe long-term load holding without depending solely on hydraulic pressure.
Hydraulic pressure extends the piston, while a heavy-duty internal spring automatically retracts the piston when pressure is released, improving operating efficiency.
The aluminum cylinder body provides exceptional strength while reducing overall equipment weight, making it ideal for mobile lifting applications.
The piston rod is manufactured from high-strength steel with a hard chrome-plated finish for superior wear resistance, corrosion protection, og lang levetid.
Heavy-duty composite bearings reduce friction, improve load stability, and extend cylinder service life under demanding operating conditions.
The hard-coated aluminum body provides excellent protection against corrosion, making the cylinder suitable for outdoor, marine, and humid environments.
An internal stop ring prevents piston over-extension and enhances operational safety.
The lightweight aluminum design allows operators to transport and position the cylinder quickly, reducing labor requirements and improving productivity.
Designet til kontinuerlig drift kl 700 bar (10,000 PSI), ensuring reliable performance for heavy-duty lifting applications.
