Engineering Overview & Structural Features

The HSC-LNA Series Lightweight Aluminum Lock-Nut Cylinders provide fail-safe mechanical load holding with unmatched job-site portability, forged from ultra-high-yield 7075-T6 aerospace aluminum alloy to deliver over 50% weight reduction compared to conventional steel jacks. Rated for 700 Bar (10,000 PSI) working pressure across 20 to 150 Metric Ton capacities, these cylinders allow hydraulic pressure to be completely released once the mechanical lock nut is threaded down against the body, safely securing loads indefinitely during structural bridge rehabilitation, building leveling, and long-term machinery foundation support.

CORE ENGINEERING ARCHITECTURE & TECHNICAL SPECIFICATIONS
01

POSITIVE MECHANICAL LOCK NUT HOLDING

Threaded aluminum lock nut mechanically locks the extended piston in position, enabling indefinite, fail-safe load holding without hydraulic pressure to protect against line punctures, valve leakage, or power interruptions.

02

COMPOSITE BEARINGS & HARD-COAT ANODIZING

High-performance composite guide bearings prevent internal galling and boost side-load resistance up to 5%. Deep Hard-Coat anodized treatment on all body surfaces provides extreme wear resistance and offshore corrosion defense.

03

STEEL BASE DEFENSE & HARDENED SADDLE

Equipped standard with a removable 6mm hardened steel base protection plate and bolt-on grooved hardened steel saddle to protect lightweight aluminum components from job-site point-load indentation and substrate gouging.

04

INTEGRAL STOP RING & FAST RETRACTION

Integral stop ring withstands full cylinder rated tonnage to prevent plunger over-travel. Heavy-duty return spring provides fast retraction, paired with standard ergonomic transport handles and ASME B30.1 compliance.
