The Benefits of Air Spring For Jacks Are Mainly Reflected In The Following Aspects
1. Routine maintenance
In terms of daily maintenance, due to the working process of the mechanical jack is closely connected with the rotation of the screw, mechanical jack need to periodically check the maintenance, albeit in when not in use, if you don't pay attention to the lubrication rust mechanical jack, it is easy to cause the screw rust, produce a lot of rust, stuck screw, even cause irreversible damage. And the air bag jack almost does not need any routine maintenance work, when not in use, just need to put the air bag in a cool and dry environment can be static.
2. Environment
Mechanical jack because of exposed thread, compact structure, the surface has more lubricating oil, in use, if the environment is more dusty sand, it is easy to stick to the screw of the mechanical jack, damage the equipment. And the air bag jack because of its good integrity, smooth and dry surface, can well avoid this problem.
3. Load-bearing capacity
The general bearing capacity of the air bag jack is about 3 tons or so, customized up to 15 tons or so, although not as good as the lifting capacity of the mechanical jack outstanding, but also enough to cope with most of the actual situation.
4. Initial height requirements
If mechanical jacks are used, a larger starting height is required, while airbag jacks do not require such a large starting height.
