User manual CATERPILLAR 623H BROCHURE

[. . . ] all controls , levers , switches and gauges are positioned to maximize productivity and facilitate a reduction in operator fatigue. Viewing Area Designed for excellent all-around visibility and clear sight lines to the job site, the large viewing area offers exceptional visibility to the front of the machine as well as to the cutting edge. The air conditioning unit has been relocated to beneath the cab, allowing the operator enhanced visibility. 3 Operator Comfort High productivity from a comfortable, confident operator. [. . . ] The standard Cat Engine Brake reduces brake wear and enhances machine control. 6 3 2 5 7 8 6 4 4 8 1 Structures Cushion Hitch Superior design and construction delivers long term durability. 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. 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. 7 Scraper Bowl Redesigned Bowl Caterpillar designed and built for rugged performance and reliability. The structure of the bowl sidewalls, ejector and floor have been improved for improved durability. 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. ) options are available to optimize the machine for different material types and loading conditions. gET options include standard , serrated , and Abrasion Resistant Material (ARM). 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. 8 Elevator Material Handling The stronger elevator makes the 623H capable of far more than finish work. 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.
