User manual CATERPILLAR 623H BROCHURE

[. . . ] 6 m3 25 038 kg 23 yd3 55, 200 lb 623H Features Economical Hauling System The wheel tractor-scraper, with its ability to load quickly, haul at high speeds and dump on the go, has the potential to be the most profitable hauling system on the job site. This efficiency can result in fewer machines on the job, reduced operating costs and jobs delivered in a shorter period of time. Power Train Caterpillar designed and manufactured power train components deliver the power necessary for fast loading and quick hauls. Operator Station Single joystick control of implements, adjustable arm rests, seat, steering column and room to maneuver all reduce fatigue and increase operator comfort and productivity throughout the shift. [. . . ] 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. 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. ) 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. 8 Elevator Material Handling The stronger elevator makes the 623H capable of far more than finish work. [. . . ] This excludes scraper weight and payload. Seat Belts meet SAE J386 June 1985 · Forward and Reverse Alarms meet ISO 9533:1989 · optional Information · The dynamic operator sound pressure level is 76 dB(A) when "ISO 6396:2008" is used to measure the value for an enclosed cab. The measurement was conducted at 100% of the maximum engine cooling fan speed. The sound level may vary at different engine cooling fan speeds. [. . . ]
