Advantages and key features:

1. 1.Neutral rubber belt caterpillars. They allow a considerable reduction of wear and noise. Moreover, they increase the maximum hauling speed that can be performed (up to 100m/').
2. 2.Independently driven caterpillars using vector motors. They guarantee a constant pulling power. Furthermore, they reduce energy waste and the number of moving parts subject to maintenance.
3. 3.Long belt contact length assures a good and uniform grip on the pipe, also providing a considerable pulling power on soft material with no marks or evident deformations.
4. 4.Pivoted upper caterpillars which feature a pipe squashing control system
5. 5.Motorized positioning of lower caterpillars that can be adjusted according to the pipe diameter.
