Thwaites 1.5t Power Swivel: Compact Agility Meets Heavy-Duty Performance
British Engineering: The 1.5 Tonne Swivel Dumper Built for Access
The Thwaites 1.5 Tonne Power Swivel is a compact and versatile piece of construction machinery designed for material handling in tight spaces and areas with narrow access. Combining a 1,500kg payload with a durable articulated chassis, it delivers the manoeuvrability and productivity required for construction, landscaping and utility applications.
Powered by a powerful, high-capacity Stage V-compliant Yanmar 3TNV76 engine, the machine provides reliable performance across challenging terrain. A hydrostatic transmission, Twin-Lock traction system and four-wheel drive work together to maximise grip, stability and control, while the compact size allows for straightforward transportation between sites by trailer when required.

Operator Comfort as Standard
Operator Comfort as Standard
A comfortable operator is essential for safety and productivity. The Thwaites 1.5 tonne dumper prioritises this with an adjustable suspension seat fitted with a high-visibility seat belt. The hydrostatic drive ensures smooth acceleration and braking with ease, controlled by a simple foot pedal layout that simplifies operation for drivers of all experience levels. Noise levels are kept to a manageable 84 LpA at the operator’s ear to contribute to a less stressful working environment, while the layout includes LED warning lights for all critical functions. This means that the operator remains fully informed of the machine’s status without distraction.

Safety First with the Power Swivel Skip
Safety First with the Power Swivel Skip
Site safety is paramount, and the defining feature of this power swivel dumper is its Power Swivel skip, which enables a 180° rotation (90° left and right). This capability allows the machine to tip loads in restricted areas without the need to reposition the entire dumper, significantly giving the operator greater control and reducing risk on-site. To further enhance safety, the machine is equipped with an automatic braking failsafe, incorporated directly into the rear drive motors. Standard equipment also includes LED beacons and a reverse alarm to alert nearby personnel of the machine’s movement.
