Volker Rail Beaver Lightweight Tamper
The Beaver tamper is a lightweight track tamper owned by Volker Rail. It has a top speed of 20mph and due to this, it is taken to work sites by lorry, rather than self propelled on the mainline.
The Volker Rail Beaver tamper has 4 arms at each corner of the machine which extend, support, and lift the unit.
A centre pivot extends from underneath the tamper, which is used to help rotate the machine once off the ground. Following rotation, the centre pivoting arm can be retracted, and the lorry can be positioned underneath the tamper before taking it away.
Tampers are used in engineering possessions to compact freshly laid ballast around the railway sleepers.
