Since selling its first CT12 in 1983, Mastenbroek has made several refinements, such as incorporating a larger, full-width tipping hopper, which reduces spillages when loading. The hopper is fully visible when the operator cabin is raised to its highest position, and its variable-speed conveyor provides a free-flow discharge for aggregates of varying viscosity. As well as allowing the operator to place materials into trenches accurately, the hopper means the CT12 can be used as a dump truck to, for example, haul aggregate along pipeline rights of way.

At the front of the CT12, Mastenbroek’s variable height, variable speed, and 180-degree swing conveyor makes it easy for the operator to place backfill material directly into a trench or the hopper mounted on the trencher.

Inside the ROPs and FOPs-certified cabin, the controls have been brought closer to hand and feature an improved ergonomic design. Mastenbroek has also replaced the manual leavers found on previous models with electronic track controls.

With colder days in mind, Mastenbroek is now fitting heated windows to the front and right-hand side.

The CT12 can also be specified with a 360-degree camera system to give the operator complete visibility of their surroundings.

A critical part of Mastenbroek’s most recent design upgrade is operator and service engineer access to the machine. A new front-mounted ladder provides easy access to radiator levels, and side-mounted wide-opening doors facilitate access to the CT12’s 248hp Volvo Penta D8 eight-litre six-cylinder Tier 4 Final emission engine.

Mastenbroek has now mounted the hydraulic oil cooler independently to the engine radiator, with both have opening grills for easy access and cleaning. A new central greasing system has been developed.

The 2022 CT12 features a redesigned operator cab that offers more internal space without increasing its footprint. Mastenbroek has also improved access to the cab with a larger door and upgraded steps and handrails.

Once inside the cab, the controls have been brought closer to hand and feature an improved ergonomic design.
