Mastenbroek Unveils Utility Trencher Designed Specifically for North America at CONEXPO-CON/AGG


The UK-based manufacturer of self-propelled trenchers and crawler trucks will use North America's largest construction trade show to unveil the Bulldog, a small footprint, compact, yet incredibly powerful trencher designed to meet the need of utility cable and pipeline layers.

The Bulldog, which is 10.9 m-long, is designed to work in confined areas, and its forward discharge conveyor system retracts to give a 2.5 m-width making it is easy to transport.
Borrowing much of Mastenbroek's engineering prowess from the existing 17/17 trencher, the Bulldog features a new engine and enhanced digging mechanism.

The new trencher features a Volvo 8 l engine offering the ideal combination of power, efficiency and emissions. It is combined to a hydrostatic drive system developed by Mastenbroek to power the new heavier digging mechanism, which can achieve the 6’ trench depth required by U.S. cable layers.

The Bulldog also features an offset cutting head and forward swing conveyor making it ideal for operating in cities and on highways where access is restricted and excavated material needs to be loaded onto trucks for removal offsite. A steerable undercarriage enables curved trench lines, and the track lift allows the machine to straddle raised pedestrian walkways.
