The forage transport trailer is the logical link for an efficient transport of quality feed between modern forage harvesters and the fodder silo. It maximizes utilization of the forage harvester, thereby paying a valuable contribution to reducing the time needed for harvest. As well as transporting grass and maize silage, the BERGMANN forage transport trailers can also be used for other forage, such as whole crop silage, wood chips and many other biomass products. The wide range of BERGMANN forage transport trailers has been developed for agricultural enterprises for which speed and economic efficiency are key. Rapid unloading and thus superior performance are ensured through the combination of a robust, conical cargo space, a scraper floor with four solid round-link steel chains with an overall breaking load of 100 t, and a powerful scraper floor drive on both sides. The HTW 40 forage transport trailer without dosing rollers has a load volume of 39 to 42.1 m³. The HTW models without dosing rollers are especially suited for rapid unloading of large fodder volumes next to the silo. They can be unloaded in less than a minute. The bogie chassis with parabolic springs and lower pivot point allows large swing angles for good all-terrain capability, easy driving over silos and easy handling on the road. To ensure low ground disturbance on the field – especially on light, peaty soils with low weight-bearing capacity – various tyre variants with ideal rolling and rollover characteristics in sizes up to 800/45 R26.5 are available. A follow-up steering to minimize disturbance of the sensitive sward is standard. A tandem chassis with 300 mm hydraulic axle compensation for a vehicle gross weight of up to 24 t is optionally available. In combination with the hydraulic axle compensation, various tyres sizes up to 800/45 R30.5 are available. For the HTW series, many convenient optional extras are available, including a cargo space cover, forced steering, LED working lights and an automatic central lubrication system. It can be operated via ISOBUS.
