In the competitive landscape of construction plant machinery, the Thwaites 3t Power Swivel Dumper delivers the perfect balance of power, payload and manoeuvrability.

Built in Leamington Spa, England, the Thwaites dumper features a fully welded steel plate skip with reinforced box sections, with a reinforced box section fitted throughout key impact areas to minimise damage and extend service life. Power comes from a Stage V compliant, water-cooled Yanmar engine, specifically the Yanmar 3TNV86CHT diesel engine, producing 33.3 kW (45 bhp) and 142 Nm max torque for optimum traction and control. Paired with a hydrostatic drive transmission, durable gearbox and heavy-duty axle, it delivers smooth performance, excellent manoeuvrability and travel speeds of up to 23.8 km/h. With a 3,000 kg maximum safe load and 1,760-litre heaped capacity, this 3 tonne dumper is built to move more material, more efficiently.

The standout feature of this machine is its hydraulically operated 180° swivel tip skip, enabling operators to discharge loads 90° to the left or right without repositioning the dumper. This hydraulic system improves efficiency, reduces unnecessary movements and allows materials to be placed accurately alongside trenches, excavations and restricted work areas. Combined with an 8.0m turning circle, it delivers exceptional versatility on busy jobsites and offers significant advantages over a traditional front tip dumper when working in confined spaces.
