Machinery and equipment: Special 4-axle grain trailer manufactured by Irish firm

Christened 'The Beast' at their Garyhill, Co Carlow, facility, this special trailer made by Smyth Trailers was shipped to Denmark.

Smyth Trailers have completed the first 4-axle trailer in the company’s 23-year history.

The trailer was custom fabricated at their purpose built facility in Garyhill, Co Carlow, for a customer in Denmark to haul grain.

It was ordered through and sold by Danish importer Tipvogn Salg.

The trailer is based on the Irish trailer manufacturer’s popular Fieldmaster range.

It has been narrowed by five inches to the customers’ specification of 2.54m (8.3ft) wide, but the most noticeable size specification is the extension of its length to 9m (29.5ft). This gives the trailer a payload capacity of 35 cubic metres.

The body is manufactured from high yield steel and is fitted at the front with a catwalk for easy and safe access to the payload.

It has a hydraulically controlled tailboard at the rear.

Connecting the trailer to the tractor is a 360 degree swivel hitch, for added safety.

An optional hydraulic jack leg was also specified, for greater flexibility and improved ground clearance, as opposed to the traditional drawbar-mounted option.

The body is tipped by two high-capacity hydraulic cylinders which are chrome plated to reduce seal wear and to increase reliability.

Everything is fitted onto a high-strength chassis manufactured from 250x150mm box section steel,l in conjunction with 100x150mm box section steel floor runners.

Underneath, the chassis is fitted with Smyth’s own heavy-duty spring suspension, which greatly reduces flex in the spring, adding to the trailer’s stability.

The design is also capable of handling greater weights than more traditional designs.

For ease of maintenance and improved component lifespan, the suspension system is fully greasable on all pivot points via a centralised greasing system.

The most noticeable feature on this trailer is the four high-speed (105km/hour) commercial axles, which are fitted with 420mm by 180mm brake shoes for maximum braking efficiency.

The front and rear axles are equipped with passive steering systems in order to maximise manoeuvrability and reduce tyre scrubbing.

These axles can be hydraulically locked in the straight position, to effectively turn off the steering system, for example when reversing. 

Mated to the axles are 600/55/22.5 low ground pressure tyres, which reduce soil compaction and increase the trailer’s weight carrying capability and stability.

Completing the package, a single-leaf parabolic spring is fitted to the drawbar for improved operator comfort and reduced hitch wear on the towing vehicle.

All Fieldmaster trailers are fitted as standard with full LED lighting which consists of double LED tail lights at the rear, with single LED tail lights fitted to the top of the hydraulic door option.

Amber LED side lights and white LED front marker lights complete the package.

Optional LED reversing lights, which consist of two lights fitted to the rear, and one each side up front, were added to this trailer, for ease of use in the dark.

These lights are engaged automatically when the body is raised, once the parking lights are switched on.

For safety, a warning LED strobe light is fitted to the rear, and there are reflective markings on each side and on the rear.

The trailer was completed in Carlow by shot blasting followed by priming and a two- pack polyurethane paint which is baked on.

For added safety, all trailers come as standard with a safety prop for working under the raised body, and hose burst valves are fitted to the hydraulic rams.
