With the 824H and 834H, you get a purpose built machine that provides industry leading uptime, safety, serviceability and operator comfort.Purpose Built Front LinkageCat coal scoops have the unique capability of maximizing your production by both dozing and carryinga load with each pass. A purpose built hydraulic system is optimized for use with this work tool tomaximize machine productivity and efficiency.Auto Idle Kickdown (AIK) (834 only)If an operator is not actively operating the machine for a period of time, the AIK system will temporarilyreduce the engine speed to save fuel. After an automated engine speed reduction, the system willautomatically resume the engine speed to the previous setting when the operator engages the implementcontrol pod of the F-N-R switch to the STIC™ Steer.Impeller Clutch Torque Converter (ICTC) Left Pedal ControlThe ICTC works with throttle lock to allow the operator to modulate rimpull to the wheels and slow themachine down without reducing engine speed. This allows the machine to maintain full hydraulic powerfor blade and steering control which gives the 824H and 834H a hydrostatic feel while keeping the benefits ofthe world’s most efficient and powerful drive train and powershift transmission with lock-up control system.Oscillating Rear AxleThe fixed front, oscillating rear axle ensures four-wheel ground contact for optimum traction and stability.The front axle is rigidly mounted to the front loader frame, while the rear axle is allowed to oscillate.This configuration allows the operator’s view of the scoop to remain constant as the rear axle oscillatesenabling the operator to maintain a smooth and properly graded work area in any underfoot conditions.Load Sense SteeringThe steering system utilizes a variable displacement pump for maximum machine performance by directingpower through the steering system only when needed. This improves efficiency and reduces heat build up.3ReliabilityMaximizing uptime, long life – it’s what you expect for your bottom lineCat C15/C18 Engine with ACERT™ TechnologyThe Cat C15/C18 engine with ACERT technology is U.S. EPATier 3 and EU Stage III compliant.

A sculpturedcylinder block provides greater strength and is lighter weight.Cat Planetary, Power Shift TransmissionElectronic shifting provides smooth, consistent shifts.Large diameter clutches coupled with four planet geartrains provide added durability for extended, trouble free life.StructuresCombining the use of robotic welding and castings incritical high stress areas, more than 80 percent of themachine structure is robotically welded to provide highlyconsistent welds and increased strength. Castings are alsoused in several areas to increase strength by helping spreadthe loads and reduce the number of parts.Axle-Shaft, Oil Disc BrakesThese brakes are adjustment free, fully hydraulic andcompletely sealed. Disc face grooves provide coolingeven when brakes are applied for a longer component life.• Location of brakes allow for improved serviceability.The axle shaft brake design allows for brake servicewhile leaving the final drive intact.• Axle-shaft brakes require less force by operating on thelow torque side of the axle. Combined with improvedaxle oil circulation for increased cooling, the oil-enclosed,multiple disc brake design improves durability.4SafetyBuilt to protect youEntry and ExitGetting on and off the machine is one of the leading causes of injury on a job site. Cat coal scoops havea number of features to ensure your operator gets safely on and off the machine. They include primaryand secondary stairwell exits, punch stamped tread plates, ground level nighttime stairwell light switch,full perimeter railings on upper platforms, side platform emergency egress and toe kicks and optionalroading fenders.Rearview CameraWith the new optional rearview camera, visibility is greatly enhanced. The camera is located in a pocketon the grill to protect it from damage and the elements. The camera can be set to activate only when thetransmission is in reverse to help eliminate distractions in the cab, especially when in dark environments.VisibilityCat coal scoops offer a number of standard and optional features to enhance job site visibility.Standard and optional features include articulated wiper/washer system with intermittent features,optional rear vision camera, optional high intensity discharge lights, optional warning beacon andoptional turn signals.5ServiceabilityEasy to maintain. Easy to service.Optional Swing Out Radiator FanThe optional swing out radiator fan provides for easy accessto the radiator cores for easy cleaning and inspection.Optional Auto Reversing FanThe fan reverses automatically at preset intervals to removedebris from the inlet screen. It can also be reversed manuallyfrom the cab.Hydraulically Driven Demand FanThe demand fan automatically adjusts fan speed for optimalcooling, resulting in reduced power draw on the engine, betterfuel efficiency and more power for hydraulics and rimpull.Component AccessSwing out doors on both sides of the engine compartmentprovide easy access to the engine oil dipstick and filler spout,S·O·S SM ports, fuel filters air conditioner compressor, engine oilfilters, alternators, starting receptacle, air filter service indicator,cooler fill and ether starting aid. There are also ground levelviewable sight gauges on all major systems and centralizedremote pressure taps.Shutdown and Lockout FeaturesAn electrical disconnect switch and hydraulic lockout switchallow service technicians to perform maintenance while themachine stays static. Other shutdown or lockout devicesinclude ground level engine shutdown and ground levelsteering hitch lock lever.Operator ComfortBest-in-class working environmentBest-in-Class Working EnvironmentA comfortable operator is a productive operator, which is why Caterpillar has designed the 824H and834H with a best in-class working environment for this size scoop. The world class cab incorporatesfeatures for operator comfort and ergonomics, visibility and ease of operation.An updated Implement Pod is fully adjustable and designed for low-effort comfort. Switches andcontrols are located within easy reach of the operator.Interior noise levels are reduced to a quiet 73 dB(A).Options include heated seat for cold weather operations and Bluetooth, MP3, or satellite radio options.STIC Steering System (834H only)The STIC steer controller uses a single lever for steering and transmission control.
