Dorvic caterpillar action skates operate by the action of an endless roller chain revolving around the centre member of the body, this allows very large weights to be supported and moved. This principle provides an extremely low coeffiecient of friction, usually between around 3% to 7% of total load.
Supplied in various designs and capacities. Models from 15 tonnes to 400 tonnes per skate. Can be used in multiples, either normally in the chain downward position or inverted to act as a skid bank. These heavy duty skates can also be supplied with side guide rollers for running along tracks. (Details on request.)
Heavy Duty skates are all steel construction with hardened centre load plates and alloy steel roller chains.
Typical Applications:
* All types of machine tools.
* Houses and other buildings.
* Oil rig installations.
* Bridge building.
* Ship building.
* Cast concrete sections.
* Large fabrications.
* Transformers, generator, and turbines.
* Large diameter pipes.
* Heavy doors and shields.
* Used inverted as skid-banks. |

The wheelers strong loads are used to move on the ground with economy and safety, of the heavy and bulky loads (machine tools, boilers, tanks, transformers, constructions, etc)
Constituted by a chain without end, with large rollers, out of tempered steel, travelling around a core between two notched side cheeks. At least five rollers are in contact with the ground.
Pivoting plates with crown of balls largely dimensioned, allowing the orientation of the wheelers compared to the load and ordered by tillers of direction.
Compensation fixed plates of the same height.
Surface striated to avoid any slip of the load.
Bars of alignment out of stretched round steel, positioned in the notches envisaged in the cheeks of the wheelers, allowing to ensure parallelism during displacements.
