Caterpillar has added the model 300.9D VPS (Versatile Power System) to the Cat® range of mini-hydraulic excavators.
The design of the 300.9D VPS allows the machine, in conjunction with its separate hydraulic power unit, to work either with its diesel engine or from a remote electrical power source, with no loss of performance. Having an electrical drive system remote from the machine enhances utilisation and rental options. The 300.9D VPS can be rented alone for regular applications, or with the hydraulic power unit when the job requires low noise and zero emission.
