Single-Acting Lock Nut Hydraulic Jacks

Sintash Machine Single-Acting Lock Nut Hydraulic Jacks are advanced and exceptionally safe equipment for lifting and providing long-term support for heavy loads in various industrial, construction, and civil engineering projects. These single-acting jacks lift the load using hydraulic pressure and then, with a mechanical lock nut or locking collar that engages with the jack body, securely hold the load at the desired height with complete confidence, without requiring constant hydraulic pressure. This feature provides outstanding safety for applications where loads need to be held for extended periods.

Committed to quality and safety, Sintash Machine manufactures its single-acting lock nut jacks using the best high-strength alloy steels and precision engineering. The meticulous design of the cylinder, piston, and especially the lock nut mechanism, ensures smooth, reliable, and error-free operation. The contact surface of the lock nut with the jack body is designed for optimal load distribution and to prevent stress concentration. Piston retraction in these jacks is typically achieved by gravity (load return) or, in some models, with the assistance of an internal spring.

Sintash Machine single-acting lock nut jacks are offered in various capacities and stroke lengths to meet a wide range of needs, including bridge lifting and support, piling and foundation work, precise installation and leveling of heavy machinery, ship repairs, and other maintenance and construction operations where load safety and stability are paramount. These jacks often feature an overflow port to prevent over-stroking and corrosion-resistant finishes to enhance durability in harsh working environments.
