Trailer PRONAR T8724

PRONAR T8724 is the latest monocoque trailer based on the proven design of T5514FR, T6016FR and T6718FR models.

The PRONAR T8724 trailer is intended for large farms looking for high performance and machine efficiency. The T8724 model has a tridem suspension with a fixed central axle and two actively steered axles for significantly easier manoeuvring. The suspension is reinforced with six parabolic springs with equalisation arms. Efficient braking is ensured thanks to double-line pneumatic brakes with an automatic braking force regulator.

Impressive dimensions of the loading case (8700 mm in length, 2300 mm in width and 1500 mm in height) enable the transport of cargo with a total mass of 23.5 tons. Optional equipment includes 800-mm aluminium sidewall extensions increasing the capacity of the trailer to the whole 45 m3. Convenient control of the rear tailgate using an electric panel.

Thanks to the extensive range of optional equipment prepared by PRONAR (including the reversing camera, tipping to the right or left or additional chutes), the trailer can be configured according to the requirements and needs of the user.
