Volvo CE has developed an all-electric mini excavator, which it is now demonstrating in prototype form. The machine is powered by the latest generation Li-Ion battery technology and is said to be highly efficient. Volvo CE points out that the machine is a prototype intended to test the concept and that its configuration will be likely to change during development. The 3.5tonne machine also does without conventional hydraulic circuits, marking it apart from currently available electric excavators. Lars Stenq
New developments in asphalt compaction offer performance gains for contractors, with future innovations being unveiled – Mike Woof writes
Advanced asphalt compactors are offering huge gains in performance over previous generation machines. Better working quality and finish is claimed for the latest machines, while future developments will offer sophisticated solutions.
The new ARX 91 articulated tandem roller from Ammann is designed as a high productivity compactor that can be used on both thin and t
The latest compaction technology offers users the benefits of more accurate performance by combining heat detection and compaction metering with GPS In Europe several leading manufacturers now offer more accurate compaction technology, with Ammann, BOMAG, Dynapac and Hamm all having developed advanced control packages. The technologies vary widely but the advantages are broadly similar, with smart compaction allowing the user a greater degree of control over the compaction process and delivering major reduc
Hamm is claiming a first with its hybrid 9 tonne HD+ 90i PH tandem roller. The German manufacturer believes that it is the first roller manufacturer to develop a production-ready machine. Most hybrid solutions, as in the case of cars, combine an internal combustion engine with an electric motor. Hamm has instead combined an internal combustion engine with a hydraulic system for the tandem roller. Although the maximum load is used regularly for compacting, it is always just for a few seconds at a time.
