Build quality and reliability

Decades of JCB expertise and innovation has gone into the 3T-1 to produce and exceptionally rugged and durable machine.

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.

All new JCB site dumpers benefit from finite element analysis and rig testing to ensure superior structural strength and durability. Cold cell testing guarantees starting performance down to -15°C.

The 3T-1’s heavy-duty damage-resistant articulated chassis and skip helps 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.

Ease of operation

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

2-speed hydrostatic transmission with permanent 4-wheel-drive offers smooth, uninterrupted power delivery, high travel speeds, exceptional off-road performance, great traction and safer operation.

Easy and fast servicing is essential to any dumper, so the 3T-1 features exceptionally easy ground level service access with a tilting seat base and engine canopy that provide maximum access to all areas.


For operator protection, a folding, hinged ROPS frame is fitted as standard. A full-width steel steering column also shields the operator and operating platform from falling material.
