824 P-Tier Wheel Loader

The addition of enhanced visibility and radar object detection systems improves situation awareness and can help prevent costly damage to machines and equipment. The addition of the advanced vision system and obstacle intelligence can help lower total cost of ownership and machine downtime.

• The advance vision system integrates two digital cameras on the rearview mirror platforms and integrates those views, along with the rearview camera view located at the rear of the machine, into a dedicated single display within the cab.
• A dedicated, secondary display is larger and digital cameras provide a higher quality visual compared to analog cameras
• Dynamic reversal projected path lines assist the operator in visualising the anticipated reversal path of the loader based on its articulation in order to provide better line of sight to objects or people that may be directly within that path
• Lines are overlaid within the rear camera view on the dedicated monitor.
• Distinctive audible alarm notifies the operator when an object is detected with the beep speed increasing as an object comes closer to the loader

Production class P-tier loaders will continue to utilise the durable axles implemented with the K-II series machines. The 744 and 824 will continue to use the TMV axles while the 844 continues to use the ZF MTL axles.

Benefits

• Front input bearings and brake discs are pressure lubed, enhancing cooling and extending component life.
• Deeper final drive ratio lowers torque on sun shaft and differential resulting in increased durability.
• Spiral bevel pinion and gears have improvements of 500% and 158% respectively to increase strength and durability.
• Axle shaft diameter and bearing size increased to withstand higher torque.
• Brake retractors and automatic self-adjusters were added to eliminate brake drag and maintain a constant brake running clearance increasing brake compliance, reducing fuel consumption and heat.
• Larger capacity front axle input bearings were added to increase reliability and durability.
• Differential locks are a low-pressure open circuit system that uses axle oil increasing reliability and durability.

Electrohydraulic (EH) controls allow for increased functionality to customise machine operations. Operators can adjust settings based on preference to increase productivity across a range of job site applications.

Benefits

• Enable soft hydraulic stops to select how abrupt the bucket or boom stops when end of travel is reached or when the lever of the joystick is released.
• Personalise both multi-function buttons, incorporated into the joysticks with up to 9 options selectable from the monitor.
• From the factory multi-function 1 is set as kickdown and multi-function 2 is set as the horn
• P-tier production class loaders may be equipped with low effort, shorter throw single axis controls or joystick controls.
• Set and store up to 10 different attachment configuration settings including flow, responsiveness, and other modes through the monitor for the most frequently used attachments in your fleet.

With improvements to the electrical and hydraulic routing and features such as ground level servicing and Quad Cool, customers get an upgraded serviceability experience.

Benefits

• Wire harness routing has been enhanced and additional retention points have been added to reduce rubbing
• Quad Cool cooling system places coolers in a unique boxed configuration that is isolated from the engine heat for increased efficiency and durability. Ground-level daily service checks and fuel refill are conveniently grouped at ground level on the left side of the machine for easy access
• Factory installed auto-lube system is offered as standard equipment. Automatic greasing takes place while the machine is working which is more effective for grease distribution.
• The pump manifold has been removed from the articulation area to simplify ease of service.
• Controllers and fuse panel are all protected from the environment while also being more serviceable from inside the cab
• The hydraulic reservoir on the 744 P-tier and 824 P-tier has been relocated to the engine compartment for reduced complexity and improved hose routings.

P-tier production class loaders pack more power and burn less fuel than previous series machines helping increase productivity to keep up with all the demands of the sites they work on.

• All P-tier Production Class Loaders have received a net kilowatt increase (see chart below) and burn less fuel compared to K-series machines.
• The 824 P is powered by a 9.0L engine compared to the 13.5 L found in the 824K-II
  • No loss in productivity across any operations compared to K-II machines
  • 8-12 percent improvement in fuel consumption, up to 16 percent improvement in fuel efficiency compared to K-II
  • Lower cost of maintenance due to smaller engine oil capacities.
• Shuttle Shift minimises the chance for an operator to make a poor shifting decision; shuttle shift allows a commanded direction to change while still moving.
• Standard Automatic Ride Control improves operator comfort and material retention when traveling over uneven terrain.
• Standard Lockup Torque Converter adds additional torque and improves fuel economy during material transport.
• Dedicated steering pump improves multifunction performance and fuel efficiency while also enabling faster steering, bucket raising, and cycle times compared to previous series.
• 744 and 824 come with transmission improvements containing improved lockup logic to improve performance and shift quality, updated speed sensors that improve low torque shifting for smoother accelerations, and improved downshift performance and reduced engine speed drop when going into piles.
