SCOTLAND-built Rokbak haulers have been proving their worth in demanding conditions in Canada.
Half a million tons of sand and gravel are produced every year from Calgary Rolling Mix Concrete’s crushing operation in Alberta, Canada, to provide concrete for applications ranging from foundations and walls to driveways and patios.
The firm employs a large fleet of heavy equipment, including three Rokbak RA40 articulated haulers, supplied by local dealer Headwater Equipment.
The RA40 has a haul capacity of 38 tonnes. Each hauler has been utilised at a pit in Carseland, hauling large amounts of material with a 66-degree dump angle and dual-slope tail chute that speeds up material ejection.
Two RA40s were delivered to the site in 2023, with a third unit arriving in 2025. Excavators load overburden into the RA40’s all-welded body to transport sand and gravel across Carseland Pit for production.
The RA40 body is fabricated from high-strength 1,000 MPa yield steel. Finished in Rokbak’s signature sand-coloured paint, the haulers have made an impression.
“The Rokbak dump truck is ideal for our operations at Carseland Pit,” said Morris Roberts, Rolling Mix Concrete’s service and purchasing manager. “Since the RA40s arrived, operator feedback has been overwhelmingly positive. They’ve praised the fuel efficiency, which is saving us money, but also the auto-lube system, visibility and cab comfort. We understand a smoother ride translates directly to higher productivity.”
Operator Renato Angelozzi added, “The cab is comfortable and quiet, even on rough ground. The visibility is excellent, and the controls are simple and responsive. You don’t feel worn out at the end of a long shift, which makes a big difference.”
The RA40 is designed and built entirely in Motherwell. Its fully automatic transmission is designed to deliver ‘smooth, responsive’ gear shifts. Inside the cab, a HVAC and airflow system provides comfort and control.
Safety and durability features include force-cooled multi-disc brakes, complemented by an electronically activated exhaust brake and a six-stage modulating transmission retarder.
At Carseland Pit, one truck has logged approximately 5,000 hours and 45,000km, another has reached roughly 2,500 hours and more than 20,500km, while the most recent addition has already accumulated around 300 hours and over 2,000km. Each truck typically hauls material on a 0.75–1km route one way, for an approximately 2km round trip.
“It’s fantastic to see the RA40 trucks performing so strongly at Carseland Pit,” added Greg Gerbus, regional sales manager at Rokbak. “We design these haulers to combine strength, efficiency and comfort, and the feedback from Rolling Mix Concrete proves that.”
