A complete range of foam and air inflatable dock seals as well as rigid, flexible and air inflatable dock shelters.

 Dock levellers are well-designed solutions for precisely compensating the differences in height between various lorry floors and ramps. With dock levellers, the load can be moved in or out of the lorry in a single horizontal movement.
 
 Dock shelters protect the goods to be loaded from adverse weather conditions, save energy costs and prevent drafts that could result in staff shortage due to illness. When combined with a dock leveller, complex canopies and ramp assemblies are not required.
