    OPERATOR COMFORT

    High productivity from a comfortable, confident operator.

    SPACIOUS CAB

    With a 21% larger cab, H Series scrapers offer a comfortable working space. The larger cab and wider door make getting in and out of the cab easier. The increased glass area enhances visibility around the machine.

    STEERING COLUMN

    The steering column and pedals have been relocated for more comfortable operation when the seat is angled during machine operation. The telescopic and tilt adjustable steering column maintains a comfortable driving position regardless of operator size.

    STANDARD COMFORT FEATURES

    The H Series cab is equipped with features designed to maintain operator comfort. Standard comfort features include: coat hook, lunchbox storage platform with strap, air conditioning, heat, and radio-ready.

    SEAT OPTIONS

    H Series scrapers use the Cat Comfort Seat with additional travel to allow the operator to position themselves for optimal comfort and productivity. The seat rotates up to 30 degrees to the right for a more comfortable position during loading and 30 degrees to the left to make getting in and out of the cab easier. For unparalleled ride comfort, H Series scrapers are equipped with the Cat Advanced Ride Management (ARM) seat suspension which uses an active suspension to dampen vibration and minimize end-of-stroke shock loads to the operator.

    INTEGRATED TECHNOLOGIES

    The optional Sequence Assist and Cat Grade Control automate many repetitive operator tasks.

    T-HANDLE IMPLEMENT CONTROL LEVER

    The redesigned control lever puts all of the scraper functions in the palm of the operator’s hand. The low-effort lever and convenient push-button and thumb wheel controls are ergonomically placed for minimum arm movement.

    POWER TRAIN – ENGINE

    The Cat® C13 ACERT™ engine is built for power, reliability and efficiency.

    ACERT TECHNOLOGY

    The Cat® C13 ACERT™ engine continues the evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability. The engine is available with either U.S. EPA Tier 3/EU Stage IIIA equivalent emission configurations or U.S. EPA Tier 4 Interim/EU Stage IIIB certified emission configurations to meet the needs of contractors around the world.

    EMISSIONS

    Machines equipped with engines meeting U.S. EPA Tier 4 Interim/EU Stage IIIB emission standards are equipped with a Cat Clean Emission Module to deliver the performance and efficiency that customers demand while meeting emission requirements. Machines equipped with the U.S. EPA Tier 3/EU Stage IIIA equivalent engines are equipped with a muffler in place of the Cat Clean Emission Module.

    CAT CLEAN EMISSION MODULE (CEM)

    CEM is an exhaust aftertreatment package consisting of a diesel particulate filter, and control systems. The CEM reduces particulate emissions using passive and active regeneration during normal engine operation.

    CAT NOX REDUCTION SYSTEM (NRS)

    The Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.

    DIESEL PARTICULATE FILTER REGENERATION

    Regeneration is the removal of soot from the Diesel Particulate Filter (DPF). The Aftertreatment Regeneration Device (ARD) is used to regenerate the DPF. The DPF traps both particulates and ash, the ash is removed at regular service intervals.

    POWER TRAIN – TRANSMISSION

    More power to the ground for greater productivity.

    ELECTRONIC TRANSMISSION

    The Cat eight-speed forward one-speed reverse Electronic Clutch Pressure Controlled (ECPC) transmission features enhanced shift control logic with anti-hunt shift strategy for speed continuity, and to ensure constant shift times.

    Tractor gears 1-2 – converter drive for increased torque, gears 3-8 – direct-drive for drive train efficiency.

    Transmission Hold maintains converter drive for maximum rimpull or holds current gear for best control.

    Programmable Top Gear manually sets top gear available (3rd-8th) to match conditions or speed.

    Neutral Coast Inhibitor prevents transmission shifts into neutral while moving.

    SMOOTH TRANSMISSION GEAR SHIFTING

    The 623H features ECPC Shift Torque Management (STM), with improved Shift Control Logic (SCL) and Part Throttle Shifting (PTS). These features allow smoother shifting and greater acceleration on grades while torque is maintained through the shift changes. SCL also provides automatic shift selection that is more specific to the desired machine operation, and downshifts when needed for maximum acceleration when increased throttle is applied. PTS allows shifting at lower speeds during part throttle operation, resulting in improved part throttle fuel economy, quieter machine operation, and better maneuvering in reduced speed operating conditions.

    BRAKE PERFORMANCE

    The 623H uses hydraulically-actuated wet disc brakes for exceptional brake performance. The standard Cat Engine Brake reduces brake wear and enhances machine control.

    STRUCTURES

    Superior design and construction delivers long term durability.

     

    CUSHION HITCH

    Electronically actuated with parallelogram-type linkage for exceptional strength, with two nitrogen accumulators (4) using free-floating pistons (8) to deliver a smooth ride for enhanced operator comfort and machine durability.

    • Controlled oil flow (6) dampens rebound oscillation
    • Leveling valve (7) applies pressure via an orifice (5) to automatically center the piston in load cylinder (1)
    • Steel castings are used to eliminate many welded joints and increase strength
    • Double-kingbolt design (2, 3) withstands high external forces, simplifies installation and removal

    LOCKOUT SWITCH

    An operator-selectable lockout switch, located on the joystick, locks the cushion hitch down for improved control of the cutting edge during loading and dumping.

    NITROGEN ACCUMULATOR

    Vertically mounted hydraulic cylinder transfers road shocks to nitrogen accumulators. Nitrogen accumulator absorbs and dampens road shocks, thus preventing the loads from being transmitted to the hitch components or to the operator.

    NON-METALLIC FENDERS AND FUEL TANK

    The new fuel tank is made of recyclable roto-milled polyethylene and keeps the fuel cleaner with controlled filtration and cleanout access ports. The new capacity of the new fuel tank has been increased, providing operators with 10 plus hour shifts depending on engine load factors. The new tractor fenders are made of the same highly durable, roto-milled polyethylene. The non-metallic fenders prevent material buildup when operating in sticky materials.

    SCRAPER BOWL

    Caterpillar designed and built for rugged performance and reliability.

    REDESIGNED BOWL

    The structure of the bowl sidewalls, ejector and floor have been improved for improved durability. New floor door rollers are used for longer life. The bowl uses a low profile design offering low resistance to incoming materials.

    EJECTION SYSTEM

    The powerful ejection system provides constant spreading control while minimizing carryback material. The floor of the bowl retracts as the ejector moves forward, allowing the operator to precisely control the flow of material.

    CUTTING EDGES AND CAT GROUND ENGAGING TOOLS (GET)

    A variety of Ground Engaging Tools (G.E.T.) options are available to optimize the machine for different material types and loading conditions. GET options include standard, serrated, and Abrasion Resistant Material (ARM). Most are reversible to provide long life and reduced operating costs. Contact your Cat dealer to learn more about the best tools for your applications.

    MATERIAL APPLICATION

    The 623H is ideal for windrowing, blending material as well as breaking up vegetation in stripping operations.

    ELEVATOR

    The stronger elevator makes the 623H capable of far more than finish work.

     

    MATERIAL HANDLING

    The elevator lifts material off of the cutting edge and carries it to the top of the elevator and then dumps the material into the bowl. Blending the material helps eliminate voids in the bowl for consistent payloads and uneven loading.

    CLOSED LOOP ELEVATOR HYDRAULIC SYSTEM

    The 623H elevator power has been increased by a new variable displacement piston pump and fixed displacement motor in a closed-loop circuit. The increased power enables the operator to take deeper cuts and load in a shorter distance with less elevator stall.

    REDESIGNED ELEVATOR STRUCTURES

    The 623H elevator and chain life has been improved through structural improvements to the elevator structure. Wear plates are used in place of rollers for reduced chain stretch.

    NEW ELEVATOR CONTROLS

    The elevator is engaged with a thumb roller on the joystick. The operator can choose one of seven forward and four reverse speeds to match the speed that best matches the material.

    CHAIN ADJUSTMENT

    Serviceability is enhanced through a new chain adjustment mechanism. The new scissors-style chain adjuster uses a simple tool to tighten the chain in 2.54 cm (1.0 in) increments.

    ELEVATOR FLIGHTS

    The life of the 15 elevator flights is improved in abrasive materials through the addition of high-strength, wear-resistant steel on the face of each flight.

    INTEGRATED TECHNOLOGIES

    Technology options to improve operator comfort and increase productivity.

     

    SEQUENCE ASSIST

    Sequence Assist uses integrated software and position-sensing cylinders to automate many of the tasks an operator performs when loading, hauling and dumping. The operator simply sets preferences for bowl and apron height and subsequently pushes a button to ready the machine for loading, then hauling, then dumping, and then the return to cut. The system automatically sets the cushion hitch, bowl height, ejector and elevator. Sequence Assist comes with a convenient load counter for tracking material moved. With Sequence Assist, up to 14 individual implement and machine commands are replaced by four touches of a button, allowing the operator additional time to prepare for the loading cycle and observation of the job site.

    CAT GRADE CONTROL

    Cat Grade Control is an automatic system that helps you control costs by moving the maximum amount of material with the prime earthmover which often provides the lowest cost per unit of material moved. Using satellite positioning technology, the automatic system ensures cut protection by limiting how deep the scraper will dig. The optional system is available from the factory and fully integrated into the machine and works seamlessly with Sequence Assist. Additional benefits of Cat Grade Control include putting the site plan in front of the operator for increased efficiency and elimination of rework and using the scraper for site mapping.

    WORK AREA VISION SYSTEM (WAVS)

    Cameras on the machine provide views of the cutting edge, right side and rear. The system enhances safety and provides a new way to see the cutting edge during loading and to see to the rear of the machine when performing push-load or push-pull work with another scraper.

    SAFETY

    Safety is an integral part of all machine and system designs.

    POWERED ACCESS LADDER

    A new powered access system option significantly reduces the effort required to climb into the cab. The system is a solid, stable angled ladder that folds out from underneath the cab. It is activated from a keypad located behind a service door at ground level. Controls are also located in the cab on a keypad. The ladder provides a rigid and angled base of support for easier climbing and descent. For added safety, the steps are illuminated by LED lights. An actuator under the cab operates the step. When not in use, the ladder retracts under the cab. An audible alarm sounds if the machine moves while the ladder is down. If power fails on the machine, the operator can raise or lower the steps manually using a lever inside the cab or outside next to the ladder’s top step.

    ACCESS AND EGRESS

    Handrails and grab irons are provided for safe and secure entrance and exit of the cab as well as for performing daily maintenance.

    WORK AREA VISION SYSTEM (WAVS)

    Cameras on the machine provide views of the cutting edge, right side and rear. The system enhances safety and provides a new way to see the cutting edge during loading and to see to the rear of the machine when performing push-load or push-pull work with another scraper.
