Flexibility for emissions-sensitive work
Caterpillar has added the 300.9D VPS (Versatile Power System) to its Cat range of mini-hydraulic excavators. The versatile design of the 300.9D VPS benefits both the owner/operator and the rental company by allowing 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 utilization 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 emissions.
