A Volvo 'Rubber duck' fitted with Grab on river clearance works following floods

The Wheeled excavator is often referred to as a rubber duck' in the UK, due to the appearance and the tendency to "bob about" whilst working and travelling. A Wheeled excavator is a 360 deg excavator mounted on rubber tyres as opposed to the normal tracked undercarriage normally used. They are used for street works where the tyres eliminate the damage problem from steel tracks. The tyre also mean they can travel to and from jobs like a Backhoe under their own power and do not need a low loader and tractor unit to transport them. They are not as versatile in soft site conditions due to the higher ground pressure of the wheels. A Common usage is as Materials Handlers in waste transfer stations, often with High level cabs and longer booms fitted with grabs.
