Modular air caster units from 3.2 T to 15 T per module. Combine 4, 6 or more units for sets handling 12 T to 90 T with 360-degree rotation and low-friction positioning.
TYPE B air casters are the standard modular air film units in our range. Each module carries 3.2 T to 15 T and uses a flexible air cushion that forms a thin air film between the cushion and the floor. Because the load floats on air, moving force drops dramatically - the friction coefficient reaches 0.0005 - so a single operator can position heavy equipment that would otherwise need cranes or rails.
Units are combined in sets of 4, 6, 8 or more according to load weight, equipment footprint and center of gravity. This modular approach keeps a small inventory compatible with many machine sizes.

* 6-caster sets are available for 19.2 T, 42 T and 60 T configurations.
Air casters require a smooth, flat and sealed floor with gaps no larger than 3 mm. Epoxy-coated concrete, polished concrete and steel plate flooring are recommended. Rough, cracked or unsealed surfaces prevent the air film from forming and must be prepared before installation. We review your floor condition and provide preparation guidance before quotation.
Systems can be configured to match your equipment and site conditions. Typical customization items:
