80/40 Ton Lifting Capacity
Most common air/hydraulic jacks are rated at 22 US tons. Our JR model is rated at 80/40 metric tons— more lifting power and a larger safety margin for heavy-duty truck service, fleet maintenance, and roadside tire work.
- Rated at 80/40metric tons vs. standard 22-ton jacks
- Backed by warranty if jack fails under normal use within rated capacity
Up to 73% More Lifting Capacity
Lower Minimum Height
With a minimum height of only 7-1/2 inches, the JR80/40 Ton jack fits lower than many standard 22-ton jacks, which are typically around 8-3/4 to 9-3/4 inches.
- 7-1/2" minimum height vs. 8-3/4"–9-3/4" on standard 22-ton jacks
Even with a fully loaded heavy truck stranded roadside with a flat tire — our jack fits under, lifts up, no problem.
7-Inch Ram Stroke for Better Lifting Range
The JR80/40 Ton jack has a ram travel of 7 inches, compared with many typical 22-ton jacks that offer only about 5 to 5-5/8 inches of travel. The longer stroke gives mechanics more usable lifting range.
- 7" ram stroke vs. 5"–5-5/8" on typical 22-ton jacks
Reduces the need for repositioning during the job
Safer Controlled Lowering
Our jack requires compressed air to lower. Without air supply, the lifting piston will not suddenly descend — even if the external air line or components are disconnected.
- Air-required lowering — no accidental descent
- Piston stays in place even if air line is disconnected
Piston Will NOT Drop Without Air Supply — Built-In Safety by Design
