Spherical Lifting Air Bag
The ball-shaped chamber hugs curved and irregular loads, delivering stable lifting force from a single contact point — the answer to traffic accidents, house collapses, railway rescue and overturning heavy objects.
32 to 180 Tons of Lifting Force in Seconds
Used in traffic accidents, house collapses and other rescue scenes, the spherical bag lifts 32 to 180 tons with fast lifting speed. A single bag lifts 30–70 cm and multiple bags can be superimposed for extra height.
- High safety performance — aromatic polyamide with high-strength Kevlar cord
- Anti-static, crack-resistant — wear, oil and ageing resistant
- 1.3 MPa working pressure — 3 cm body, 7.5 cm insertion height
- Stackable — multiple bags superimposed for large-stroke lifting
- Fast — rapid lift suitable for time-critical rescue

Where Spherical Bags Are Used
Railway & Heavy Vehicle Rescue
Upright and reset derailed, overturned rail carriages and locomotives; jack up heavy tank wagons for re-railing, position correction and on-site emergency repair. Multi-layer stacked spherical airbags achieve large-stroke lifting for heavy railway vehicles.
Traffic Accidents & House Collapses
When a slab, vehicle or machine pins a victim, the spherical bag raises the load with controlled pneumatic force. Lifting pressure ranges from 30 to 180 tons with fast lifting speed and a single-bag lift height of 30–70 cm.
