Caterpillar releases new Motor Grader
Published by Claire Cuddihy,
Global Mining Review,
Building on its M Series Motor Graders, Caterpillar has developed the new Cat® 24 Motor Grader, which delivers high performance construction and maintenance of mine roads to improve mining truck efficiency.
The new motor grader features optimised weight balance and 15% more low-end torque compared to the Cat 24M. These features improve traction and help maintain consistent ground speed, especially when carrying a large load on the moldboard, working on grade, or turning under load. An 11% increase in machine weight provides additional blade down pressure and tractive force to increase blading performance, and consistent
Power-to-the-Ground controls engine power levels to offset cooling fan losses, allowing the motor grader to deliver optimum performance at all times.
Improved serviceability and lower operating costs
The Cat C27 engine with ACERT™ technology delivers reliable performance and prolongs target rebuild life by 33% over the C18 engine. The new 533-mm (21-inch), 6-speed planetary transmission and improved rear axle bevel gear and final drive extend lower power train service life by up to 33%, substantially lowering service costs.
The Cat 24 features a modular design that reduces downtime associated with the removal and installation of main components. For example, the transmission can now be removed up to 70% faster than on the 24M.
Maintenance intervals for the transmission, hydraulic filter and engine air filter, as well as service life for the transmission and rear axle fluids have been doubled, which significantly reduce service time and costs. New front axle hose routings and guards protect steering components from external hazards and improve front axle durability and reliability. A standard transmission guard protects the drop box. Gear-slip detection protects the transmission by locking the gear out when slip is monitored.
A standard fluid service centre allows for fluid filling and extraction from one convenient, ground level location to simplify maintenance, reduce downtime and lower costs. All machine filters are stacked in a centralised location for improved access.
The Cat 24 features 15 strategically located tie-off points to protect service technicians when performing certain service operations. In addition to standard mini-platforms, walkways, grab handles and non-slip steps, an available Working at Heights package offers stable, secure handrails and handholds for enhanced safety when working around the engine.
The standard rearview camera improves visibility behind the machine, while forward and side machine visibility is enhanced through optional front cameras. Inside the cab, a new standard seatbelt indicator provides visual and audible alerts when the seatbelt is unfastened, and the system reports the event to the office.
A set of two 4x4 LED lights inside the engine compartment enhances visibility for technicians during machine servicing.
Performance and comfort
The Cat C27 ACERT engine powering the new 24 Motor Grader offers a net power range from 399 - 518 kW (535 - 694 hp) and provides a 15% low-end torque improvement over the 24M. Two configurations are available to satisfy most global emission standards – US EPA Tier 4 Final/EU Stage IV for stringent emission standards, and Tier 2/Stage II for less regulated countries – both offering full power performance at maximum altitudes of 3048 m (10 000 ft) and 4572 m (15 000 ft) respectively.
The new Cat 24 motor grader includes the latest technologies to protect the machine from potential operating or maintenance issues including engine underspeed/overspeed, transmission slip detect, articulation eStop, implements lockout and fluid monitoring. Prior to starting, the machine performs a diagnostic of the coolant, engine and hydraulic oil levels and gives the ok-to-start.
