From the humble tipper trailer to giant multi-axle machines equipped with central tyre inflation and weigh cell technology, LAMMA featured trailers of all shapes and sizes.
A first venture into field machinery for Downs, the prototype DTX 18 can be used to clean or simply to load potatoes into trucks at the headland.
Transported to the field on a tandem axle, the hopper is then lowered to the ground where it may be loaded from field trailers.
Clean crop is diverted via a bypass transfer belt to the right onto the 1.2m wide, 4m reach elevator or for cleaning the crop passes over a 1.2m star or Downs Ultra module.
County Kildare-based Cross Agricultural Engineering has taken a different approach to chaser bin design with its model 46.
The 32-tonne capacity bin uses two 16-tonne compartments and two five tonne/minute unloading augers to offer additional flexibility when not used as a chaser. Cross says the unit’s construction affords use of its two sections as a drill filler, with seed and fertiliser carried and metered out individually. Its two augers can also be remotely controlled from outside the cab using a wireless terminal, to compliment the in-cab touch-screen system.
Shod on six 800/45 R26.5 low ground pressure tyres, the triple axle chaser bin uses a following axle at the rear, and air suspension to reduce its impact on field surfaces.
Needing a tractor of 250hp to operate, the model 46 chaser bin costs £115,000 with electric controls.
With three twin axle Bergmann beet chasers working in the UK, CTM Harpley now offers a 32 tonne capacity tri-axle version.
With air suspension and full steering including a crab mode, soil damage is minimized. Designed for field use, the chaser facilitates ‘just in time’ harvesting, loading beet directly into lorries and avoiding estimated losses of 15-20 from stockpiling. The chaser uses belts from sister company Ropa to convey crop forward and across to the unloading elevator.
A 350hp tractor is suggested to provide the necessary power and weight and the price is £120,000.
Future proofing itself for a potential rise in trailer weight rules, Stewart trailers has introduced an air suspension option for its range of low loader trailers.
The option costs about £1,000 per axle, allowing each of the trailer’s axles to accommodate eight tonnes. This, combined with the ability carry three tonnes on the drawbar, allows the largest trailer to achieve a 27t gross weight. Add about 10t for the tractor, then the 37t gross train weight will comply with future trailer weight propositions, something which trailer maker James Stewart is hoping should be sorted out by this harvest. He says; “It is likely trailers of this size will require an MOT, which is something we and our customers would welcome.”
In addition to their weight carrying capability, Mr Stewart says air suspension gives particularly good inter-axle load compensation, with no single axle ever over-loaded. And, because air levels can be adjusted, it also gives an appropriate amount of suspension for the load, he adds.
Richard Western showed its prototype SF18 HS trailer which features hydraulic suspension for increased stability on sloping ground and improved road travel.
Active rear axle steering allows steering in forward or reverse, and a single tipping ram is specified, said to give faster tip cycles. A fast tow pack can be fitted, offering ABS, air brakes and load sensing to allow towing at 65kph with a suitable tractor. Richard Western reports that while 14 tonnes is still its top selling trailer model, demand for 16 and 18 tonne versions is growing and that the SF18 HS will be offered in a range of sizes.
Hydraulic suspension adds £6,000 and steering axles £3,000 to trailer prices.
Fliegl UK Ltd has added a tipper trailer range alongside the push-off models it offers.
The TMK range is from eight to 20 tonnes capacity with optional galvanized greedy boards for silage and a tapered body shape for easier unloading, with flared sides to boost capacity; a low chassis version is available for easier loading.
Tandem axles are standard with 550/560 tyres, LED lights and a range of suspension and braking options. The price is from £25,000 depending on specification.
