💡 How does a single acting lift cylinder compare to standard ram jacks?
This handy design skips fancy spring returns and relies on gravity plus your handle to drop the load safely.
- Open mid chambers allow threading securing bolts straight through the tube so beams stay locked tight
- Straightforward valve layouts cut repair time since mechanics only need wrenches and seal pullers on site
- Reinforced flanges absorb shock loads better than thin stamped housings that crack under repeated hammering
