Richard Western has signed a deal with Dutch firm USA Equipment, enabling the manufacturer to produce a three-model range of push-off trailers at its Suffolk factory.
Initially, the PR4024, with tandem axles and a 40cu.m capacity will be available, with 50 and 60cu.m capacity trailers with triple axles to follow.
Both tandem and triple axle variants use 150 by 150mm high-speed axles with hydraulic or air braking options.
The company says the design of the trailer not only allows for push-off discharge, but also load compression, allowing the potential capacity of the trailer to be fully utilised, and forager harvester output to be maximised, while also potentially reducing required trailer numbers.
It says other advantages include the ability to eject in restricted spaces, such as within low sheds, and part-discharge of full loads.
The trailer body is of a monocoque design, with folded side walls for strength.
Triple axle models have a self-contained on-board hydraulic system, while the hydraulics on tandem-axle trailers operate from the tractor system. All models are equipped as standard with sprung, heavy-duty suspension to ensure an equal axle load and road-holding.
The manufacturer says the sliding system for the compression/discharge headboard uses nylon wheels with guide blocks running in I-beam guide rails, for ease of movement and high wear resistance, while headboard hydraulic pressure can be varied according to the load density required.
Opening/unlocking and closing/locking of the tailgate is governed by double-acting hydraulics, ensuring failsafe tailgate closure, and full load discharge time is 35 seconds. The use of PE1000 self-lubricating thermo-plastic ensures a grain-tight seal between the headboard and the trailer sides, allowing the trailer to be used for other purposes.
