Custom built 4.5T Tandem Axle Box Trailers With Wheels Under and Flat Top, will provide you with maximum carrying capacity in the most convenient package. Designed and built in Australia, these trailers offer exceptional quality with smart looks. The 4.5T Flat Top has an ATM of 4500kg, making it possible to move a significant load. The chassis is made with a combination of 75x50x3 trussed supports on the bottom, with 65x35x3 bars used on the top. The drawbar is 125x75x4, providing maximum strength and stability. A 10mm high tensile double safety chain is also included. The suspension is a hook and eye load share design, and the 60 round 3T tandem axles are connected to 16" wheels for a stable ride and safe load bearing. A rope rail is integrated into the flat top, allowing you to secure your load using the 20nb pipe. The pipe runs around all sides of the trailer. Other standard features include LED lights, an integrated plug holder, spare wheel, and an extra heavy duty jockey wheel. The coupling used is a 75mm fixed ring design. Checker plate is used on the floor, minimizing slippage and improving safety while loading. Trailers can be customized to meet your needs, with the largest 4.5T model being 4200x2400. All trailers are finished with an industrial quality primer and enamel top coat.
