Cat launches new grader

Caterpillar has launched a new grader designed for construction and maintenance of mine roads carrying trucks with a 200t payload.

The 24 Motor Grader has a modular design that means components can be removed and installed more quickly and easily - in some cases, up to 70% faster when compared to the 24M model. Cat Grade with Cross Slope functionality is included for improved operator productivity and haul road quality, which lowers truck tire wear, decreases rolling resistance and reduces premature tire failure, said Caterpillar.

The new motor grader features optimized weight balance and 15% more low-end torque compared to the Cat 24M. These features have been designed to improve traction and help maintain consistent ground speed, especially when carrying a large load on the 24ft-wide 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 a consistent power-to-the-ground feature controls engine power levels to offset cooling fan losses.

The Cat C27 engine with Acert technology is claimed to deliver reliable performance and prolong target rebuild life by 33% over the C18 engine. The new 21-inch, 6-speed planetary transmission and improved rear axle bevel gear and final drive are said to extend lower power train service life by up to 33%, substantially lowering service costs.

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. 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.

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, a ‘working at heights’ package is available, offering handrails and handholds for enhanced safety when working around the engine.

The machine is designed for easy mounting and accommodation of most fire suppression systems; a fire suppression system is available from the factory as an option.

The standard rearview camera improves visibility behind the machine, while forward and side machine visibility is enhanced through optional front cameras.  

 The new Cat 24 motor grader includes 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. While operating, the machine automatically monitors and alerts the operator of critically low fluid levels.
