The Thwaites 3 Tonne Power Swivel, badged MACH2080, is the step-up size from the 1 tonne class and a standard fixture on larger UK groundworks and civils sites needing higher payload per cycle. Its power swivel skip rotates independently of the direction of travel, letting the operator tip to the side without turning the whole machine around. It is hired alongside excavators of a similar class to keep material moving off the dig face.

The Yanmar ViO20-6 steps up from the ViO17 into the roughly 2 tonne mini excavator class, still with Yanmar's true zero tail swing geometry for working in confined spaces. It competes with the Caterpillar 301.7 CR and similarly sized Kubota and Takeuchi machines for UK groundworks and utility hire jobs. Its fixed rather than variable undercarriage keeps the design simpler than some rivals, at the cost of not being able to narrow down for transport.
