Marine heavy lifting air bags
Low pressure high lifting capacity
Can roll with load on land or in water
0.4-3 m lifting distance
5-8 times safety factor
Why marine heavy lifting air bags?
- Peerless lifting capacity. Cylindrical shape, low pressure marine heavy lifting bags work on volume rather than pressure to create the lift. Those lifting bags can lift 300-500 tons one piece.
- Low pressure means safer, rate pressures of Cylindrical marine heavy lifting bags normally do not exceed 2 bar.
- Big inflation height. Maximum extended height of marine heavy lifting air bags can reach 2 meters.
- Can roll under load. Different from square or rectangular lifting bags, marine heavy lifting bags can roll with load which is extremely useful for load moving.
- Heavy duty. With 6-10 plies reinforcement layers, Cylindrical marine heavy lifting bags can withstand most abrasion and puncture.
- Flexible: Cylindrical marine heavy lifting bags can be folded ,stacked, hoisted easily.
- Long life span: with normal care and maintenance, cylindrical marine heavy lifting bags should work well over 6 years trouble free.
Available Specification
- Marine heavy lifting air bags diameters vary from 0.5 m to 2.5 m
- Marine heavy lifting air bag lengths vary from 3 m to 25 m
