Huge amounts of expertise and innovation have gone into the new range of JCB site dumpers. They’re exceptionally rugged and durable, built ready to tackle anything the rental market can throw at them.

State-of-the-art manufacturing processes like robot machining, precision paint technology and innovative assembly techniques help to achieve the very highest levels of build quality.

Precision machining techniques ensure high tolerances and accurate location of your 3T dumper’s pins and bushes.

Your new JCB site dumper will have benefitted from finite element analysis and rig testing to ensure superior structural strength and durability. For further peace of mind, cold cell testing guarantees starting performance down to -15°C.

Heavy duty damage-resistant articulated chassis and skips help your machine to withstand everything. What’s more, because it articulates and oscillates centrally, strength and reliability are maximised on even the toughest work sites.

A JCB 3T dumper’s skip strength is class-leading courtesy of thick steel side walls and heavy duty steel front and base plates.


JCB 3T-1 site dumpers have simple and clear user-friendly automotive-style controls, an uncluttered dashboard and hydrostatic transmission. The end result is improved access and easier operation.
