ER-Series Heavy-Duty Machine Skates are available in different load capacities up to a maximum of 80 tons (711 kN). Low-profile construction provides increased stability while low rolling-resistance metal rollers allow for easy load movement. This type of machine skate is also known as a chain roller, a caterroller, or a roller skid, and is constructed with a series of steel rollers.

Advantages compared with others are high capacity, low cost, and a small footprint.

Use ER skates with attachable ELP load leveling plates and ES swivel turntables for turning corners. Alternatively, consider a complete set from the ERS machine skate sets.
