A new machine described as an excavator, trencher and crusher is the first of its type operating in the UK and Europe.

Sunward has focussed particularly on building small-medium sized machines, said Li Lihong of the firm. An innovative development from Sunward is its new hybrid excavator design. This 22.6tonne machine has been developed with a view to offering lower fuel consumption than conventional excavators in its size class. As fuel prices are high in China, a hybrid machine offers incentives to the customer base and is said to be most effective in operations requiring slewing, such as for production truck loading. Pow
