“Transporting long materials is one of the most difficult challenges we face in heavy haulage. As an experienced logistics service provider, we make sure our customers in every sector get nothing but the best – so we chose DOLL’s trailer combinations because they contain the very best technology. DOLL’s precise hydraulic steering really makes a difference, particularly in situations where space is tight.”

Variable loading

The steering radius adjustment for short and long bolster configurations allows you to respond flexibly to load length – while maintaining manoeuvrability.

Better manoeuvrability

The special bolster with a steering angle of up to 85° gives you a huge amount of freedom – as well as the option to make right-angle turns.

Fuel-efficient empty trips

The vehicle can be driven as a drawbar trailer, which saves you time and money and reduces fuel consumption. In addition, empty trips do not require special approval.

Perfect connections thanks to DOLL Powerboost

Easy-to-attach wire rope connections ensure efficient cable connection clamping. This ensures the battery is permanently charged – without any loss of voltage.
