Mastenbroek, the UK-based designer and manufacturer of self-propelled trenchers, has announced it has added a new engine to its innovative CT12 Crawler Truck.
CT12s manufactured in 2021 will feature Volvo Penta’s D8 engine and improved access for on-site service and maintenance.
The six-cylinder, 252Hp (185kW) EU Stage V emission compliant engine features a highly advanced exhaust after-treatment system, based on SCR technology, uncooled EGR and a diesel particulate filter.
Introduced in 1983 to install aggregate backfill for sub-surface land drainage, the CT12 has benefitted from numerous upgrades over the years. Today, the crawler truck offers the perfect combination of features demanded by construction companies operating in the oil and gas industry, including low ground pressure suspended and oscillating undercarriage with high tracking speeds. These features enable the CT12 to operate in environments where wheeled vehicles cannot access.
The discharge conveyor system is designed for controlled, accurate placement of backfill material either directly into a trench or a hopper mounted on the trencher. The front swing conveyor is controlled by a joystick for left and right-hand discharge through 180 degrees and variable height up to 2.75m. A hydraulic hopper door combined with variable speed control on all conveyors allows the flow rate of the material to be adjusted as well.
In addition to the forward conveyor, the CT12 also features a tipping hopper allowing it to be used as a dump truck to haul aggregate along pipeline rights of way
“The CT12 has proved itself over the years, operating successfully in some of the most arduous conditions, such as on saturated soils while minimising soil compaction,” says Christopher Pett, Mastenbroek’sgeneral manager. “It is a popular machine in utility applications as well, where a backfill aggregate must be placed efficiently and consistently into the trench. We are pleased to have seen increased demand within the pipeline and cable trenching industry over the last few years and believe the introduction of the D8 engine will make the CT12 even more attractive.”
Mastenbroek manufactured its first trencher in 1977, since then the company has grown into a globally respected name in trenching, machine automation through its partnership with Trimble®, subsea cutting technology, ground stabilisation and groundwater control.
