HM Trailers

Tri Axle Grain Trailers


Tri Axle - HM tri axle grain trailers are built with a rigid axle set up as standard. Options for steering include passive steering axles (connectable with a spool) or forced steering axles allowing you to turn a trailer in earlier and with automatic straightening when in reverse. The option price (view by selecting blue underlined titile above) is per axle.

Chassis - A short chassis layout has enabled us to significantly reduce the overall tipping height, allowing a sufficient tipping angle in many barns that would normally be inaccessible .

HM trailer chassis are made from 55 grade (structural) Rectangular Hollow Section (RHS). This gives greater strength for a given weight and does not allow a build-up of material on ledges. These are manufactured in a wide chassis format for increased trailer stability.


Running Gear - All trailers have sprung suspension to provide a cushion between rough terrain and the trailer. This reduces the high stress levels that are imposed on a chassis with a single mounting system, it also makes the trailers more stable when tipping by making it less likely to lift the drawbar.


All trailers have suitable under-body, chassis and wheel-to-wheel clearance for flotation tyres.


Buck - All tipping buck chassis members are welded directly to a one-piece floor sheet, minimising the overall floor height on a trailer. When lowered, the tipping buck sits on rubber blocks fixed to the chassis which provide a cushioning to the shock being transmitted from the chassis to the buck.


Side Panels - HM grain trailers all have the side panels folded horizontally in their centre and into the floor plate. This increases the side sheet strength reducing the risk of distortion from welding or loading. The top rails are made from folded sections, replaceable if they become damaged.
