The latest five C520.32 8x4 RK chassis were direct replacements for a similar group of 513bhp Renault trucks that had entered service during 2017. Supplied by Renault Trucks Scotland at Bellshill, the 5.6m wheelbase rigids feature all-round parabolic steel spring suspension and offer generous ground clearance levels when laden.
Yuill & Dodds were the pioneers of in the Scottish road transport industry. The latest C520s continue the high power, high specification eight-wheeled tipper theme, with DTI 13 engines producing maximum 505bhp between 1430 and 1800rpm; a top torque figure of 2550Nm on tap from 1000 to 1430rpm. A 12-speed Optidriver overdrive gearbox and PMR 2191 double-reduction drive axles with a ratio of 3.70:1 complete the powertrains.
Managing director Brian Yuill opted for PPG bulk alloy bodies, along with Binotto hydraulics, PM onboard weighing equipment and Harsh electric slide and go automatic sheeting systems.
The trucks are contracted for a full-life R&M maintenance package that will be carried out at the manufacturer’s nearby Bellshill dealership. Yuill anticipates a three- or four-year retention period for the new tippers. He says: “The C520 tippers are delivering good performance levels to date and they have plenty of power on tap in addition to a chassis that is tough enough for the job. The Renault Trucks carry out bulk bales and soil movements across Scotland and it’s likely that they’ll work further afield if our customers ask.”
To accommodate long-distance jobs, the C520 rigids all come with Renault Trucks’ sleeper cab, which benefits from a four-point air suspension with a ride height control system.
AST Signs provided the cab wraps for the new Renault tippers.
