The mechanical steel jack is designed on the mechanical transmission principle — one of the best lifting tools used in repair, support and similar applications. Its lifting and lowering speed is fully controllable, overcoming the shortcoming of common hydraulic jacks, whose lowering height and speed run out of control when oil leaks.
The top-quality all-steel structure makes the jack safe and durable. A compact design with a collapsible lever offers easy operation and simple maintenance, and two support stands are provided for versatile use. The lifting range is much higher than comparable units, and every jack is tested with a 25% overload. It is equipped with a fixed claw and a folding handle.
Mechanical transmission provides stable and reliable lifting performance.
Lifting and lowering speed can be precisely controlled, avoiding uncontrolled descent caused by hydraulic oil leakage.
All-steel construction with a compact design and two support positions offers durability and a wide lifting range.
Tested at 125% load, with fixed claw and folding handle for easy operation and storage.
Where oil leakage would put the load at risk — on a repair bay, a support stand or a job site where lowering must stay under control — a mechanical jack gives you full command of lift and descent. The mechanical steel jack is built for exactly that: designed on the mechanical transmission principle, one of the best lifting tools used in repairing and supporting.

Where load stability and controlled descent are critical — such as precision support or maintenance in fluid-sensitive environments — the mechanically driven jack is recommended. Its positive mechanical transmission ensures lifting and lowering speed remain fully controllable, eliminating the uncontrolled descent risk associated with hydraulic units in the event of oil leakage.
Determine the working load from the heaviest anticipated load and apply an appropriate safety margin. Each unit undergoes a 25% overload proof test prior to delivery to verify structural integrity.
Compare the operational stroke with the jack's extended lifting range. The dual support-stand configuration provides two effective load heights, extending the usable lifting envelope across varied applications.
Suitable for repair and support operations across automotive service, construction, general manufacturing and rail maintenance. The all-steel welded structure, collapsible lever, integral fixed claw and folding handle provide durable, serviceable operation with straightforward maintenance.
Mechanical transmission provides stable lifting and supporting performance.
Lifting and lowering speeds can be controlled precisely.
Mechanical operation avoids uncontrolled lowering caused by hydraulic oil leakage.
All-steel construction delivers excellent strength and durability.
Two support positions provide flexible applications and a higher lifting range.
25% overload tested, with fixed claw and folding handle for easy operation and transport.
What's the difference between a mechanical jack and a hydraulic jack?
The mechanical steel jack is designed on the mechanical transmission principle — its lifting and lowering speed is fully controllable. This overcomes the shortcoming of common hydraulic jacks, whose lowering height and speed run out of control when oil leaks.
What applications is it designed for?
It is one of the best lifting tools used in repair and support work, across automotive service, construction, general manufacturing and rail maintenance.
Is it overload tested?
Yes — all jacks are tested with a 25% overload prior to delivery, verifying the structural integrity of the all-steel construction.
What features does it include?
The top-quality all-steel structure is safe and durable; a compact design with a collapsible lever offers easy operation and simple maintenance. It has two support stands, a higher lifting range, a fixed claw and a folding handle.
Why choose mechanical over hydraulic?
Because descent speed and height remain under positive mechanical control, even where a hydraulic unit would lose control through oil leakage — making it the safer choice for precision support and long-duration load holding.
