agroliner TransMaxx - centre pivot trailer with drawbar load transfer

With Kröger Nutzfahrzeuge's "agroliner- TransMaxx", a new vehicle concept has been introduced to the market. The product name interprets maximum transport performance. The new development is a symbiosis of turntable and tridem trailers. The advantages of both systems are unified to eliminate vehicle-specific deficits at the same time.

The design of the TransMaxx is initially based on a conventional three-axle centre pivot trailer. The largest handicap of a turntable-steered trailer is, however, the limitation of the maximum permitted total weight to a maximum of 24 tonnes. In conjunction with a tractor as the towing vehicle, the possible permitted total weight of 40 tonnes cannot be fully utilised. A dolly trailer with drawbar load transfer has been built for this reason. This brings the vehicle into the fixed drawbar trailer category which means that it can be designed with up to 34 tonnes permitted overall weight.

Thanks to the extended axle spacing between the dolly trailer and the rear double-axle, the vehicle sticks to its tracks when driving fast on roads. The dynamic forces produced while driving do not need to be fielded by the tractor vehicle as is the case with a tandem or tridem trailer. The dolly trailer of the trailer takes on this task in an exemplary fashion and the trailer can therefore be moved without any problems by comparatively light tractors. The drawbar load transfer of up to 4 tonnes as well as the version with ground-protecting low-pressure tyres, both ensure that the use on the fields is practically done. Combined with the optionally available steering axles, the vehicle remains very manoeuvrable and it even enables smaller turning circles than with tridem vehicles of comparable size. The forced steering on the last axle is controlled by the dolly trailer. This means that there is no requirement to attach the forced steering system to the tractor. The air-sprung axle unit ensures balanced ride comfort.

Kröger is only offering the agroliner TransMaxx as a rearwards tipper trough vehicle initially. The trough has a capacity of up to 50 m³ and is made of aluminium. The hydraulic tailgate lifts up high above the cone of the material and is integrated optimally into the side walls so that even cargos which do not slide easily can be unloaded without any problems. A press at the front ensures additional stability during the tipping procedure. The oil supply comes from a powerful on-board hydraulic system. A prototype of this new vehicle generation has been in permanent use for 4 years already. Due to the positive experience gained, the new model is now released for sale.
