Product overview
Model 21121 is an 8x5 tandem heavy-duty plant and machinery trailer with a 6 ft two-piece drop-down mesh ramp: the ramp splits in half so it can be folded or used in stages, which makes it practical for machines with a low ground clearance as well as for loading by hand.
The trailer is built for the way plant actually arrives on site - driving onto the deck on its own power. Full checker plate covers the floor, sides and guards, the drawbar is heavy duty and reinforced, and there are drop-down stabilising legs at the rear so the trailer does not nose up while a machine is on the ramp. A front stop bar gives a machine something to push against and marks the correct loading position, and dedicated tie-down points let you chain a machine down properly rather than relying on rope.
Braking is the part that matters with machinery on board: four-wheel electric brakes with a break-safe unit, on rocker roller suspension and new Sunraysia rims with brand-new light-truck tyres. A loaded plant trailer has a high centre of gravity and a short wheelbase relative to a truck, and electric brakes on all four wheels are what make it stop predictably and legally.
The lighting package is 12 V LED, and the trailer is finished for outdoor commercial work - checker plate where machines contact, paint where they do not. It is a straightforward, repairable trailer: the ramps, legs, stop bar and tie-down points are all bolt-on or welded components that can be replaced individually rather than condemning the deck.
Typical users are plant hire, builders, landscape contractors, farms and equipment dealers moving mowers, compactors, trenchers, attachments and small machines between sites on a daily or weekly cycle.
