Thwaites 1t Power Swivel: A Compact Dumper Packed with Versatility
1,000kg payload, 180° power swivel skip and compact design
The Thwaites 1 Tonne Power Swivel Dumper is designed for construction, landscaping and groundworks projects where access is limited but material movement remains essential. Part of the trusted 1 tonne range, this compact piece of plant machinery combines a 1,000kg payload capacity with a narrow 1,195mm width, making it ideal for working in confined spaces and on sites with limited access.
Powered by a Stage V-compliant Yanmar engine and equipped with hydrostatic transmission, this Stage V dumper delivers simple, user-friendly operation and reliable on-site performance. The addition of a 180° power swivel skip increases the machine’s versatility, providing an effective solution for placing materials accurately while helping operators work more efficiently across a wide range of applications.
Thwaites 1 Tonne Swivel Dumper Key Features
180° Power Swivel Skip for Greater Flexibility
180° Power Swivel Skip for Greater Flexibility
The standout feature of this Thwaites 1 tonne is its hydraulic swivel skip, capable of rotation through 180°, allowing operators to discharge material 90° to either side of the machine. This enables precise material placement without repositioning the dumper, improving productivity and reducing unnecessary machine movement.
Whether working alongside trenches, foundations or buildings, the swivel skip provides greater flexibility than a conventional forward tipping dumper. By allowing loads to be placed accurately in confined areas, operators can work more efficiently while reducing disruption to surrounding site activities. This makes the machine particularly useful for groundworks, utility projects and landscaping applications where access is limited and manoeuvrability is essential.

Compact Dimensions for Restricted Access
Measuring just 1,195mm wide, the Thwaites 1T Power Swivel is built for confined spaces or where access is restricted. Its compact footprint makes it ideal for housebuilding, landscaping, utility works and urban construction projects where working space is limited.
Despite its small size, the machine delivers optimum stability and a user-friendly operating experience. The articulated chassis features centre-point articulation and oscillation, helping maintain traction across uneven ground and improving manoeuvrability in tight working areas. The result is a dumper that combines compact dimensions with the performance required for demanding site conditions.

Hydrostatic Transmission and Four-Wheel Drive
Powered by a Stage V-compliant Yanmar diesel engine producing 15.9kW and 66.4Nm of torque, the machine provides smooth power delivery and responsive performance throughout the working day. The hydrostatic transmission simplifies operation while helping operators maintain precise control when navigating busy sites.
Four-wheel drive motors work alongside the Thwaites Twin-Lock traction system to maximise grip and control in challenging ground conditions. These features help enable consistent performance across mud, loose aggregates and uneven terrain, allowing operators to work safely and efficiently in a variety of applications.
