User manual CATERPILLAR 740 EJECTOR BROCHURE

[. . . ] True "on-the-go" differential locks with simple operation improve cycle times and productivity. Strong, durable Cat ACERT engines and electronically controlled transmissions deliver high productivity with low fuel consumption. Engine with ACERTTM Technology ACERT Technology The Cat C15 ACERT engine introduces a series of evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability. Innovative technologies optimize performance. Advanced Diesel Engine Management (ADEM) A4 Engine Controller The ADEM A4 electronic control module manages fuel delivery and provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. Fuel Delivery Multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. [. . . ] Disengaging the foot switch opens all differential locks immediately. Transmission and Ejector Levers Finger tip controls allow easy operation and low effort. The ejector and transmission levers are positioned for easy, comfortable operation, along with the control for top gear limit, transmission hold and neutral lock. Blade Retraction Sequence The ejector blade returns to the loading position as soon as the blade retract sequence is initiated. The transmission is held in the gear selected for the ejecting cycle until this sequence is completed and the ejector control lever is returned to the float position. Suspended Pedals Easy to operate and reach with plenty of leg and foot room. They also make for easier cleaning of the cab floor by keeping the pedals out of the dirt. 6 Durability and Reliability Front Frame High machine availability maximizes productivity and lowers costs. The front frame design features a large box section and wide, stiff frame beams to handle torque loads. The divergent frame design decreases stress in the hitch area and optimizes suspension geometry. The frame design makes maximum use of robotic welding for increased durability. Rear Frame Twin-box construction minimizes stress concentrations and provides low weight with long life. Suspension The three-point oscillating axle front suspension provides unparalleled ride quality. It also protects the truck from adverse road conditions by absorbing shock loads that would reach the frame. Articulating/Oscillating Hitch The articulating hitch provides the truck with steering articulation, and the oscillation ensures all-wheel ground contact in rough terrain. Hitch Construction Two-piece construction features a durable cast steel head bolted to a hard-wearing forged steel tube. Service Brakes Oil-cooled, multiple disc brakes are continuously cooled for exceptional non-fading braking. They are designed and built for reliable, adjustment-free operation. Parking Brake Located on the center axle in an elevated position and designed to deliver higher heat capacity and abuse resistance. 7 Ejector Body Disperse loads on-the-go for faster cycles and lower spreading costs. Ejector The ejector body offers clean load ejection on-the-go and the capability to work in areas with restricted overhead clearance and soft underfoot conditions. Versatility The 740 Ejector shares the versatility of the Standard 740 Articulated Truck, operating in the same conditions, but offering unique capabilities that stretch the operation envelope. Spreading The truck can eject and spread the material while moving, reducing additional spreading and dozing equipment. "On-the go" ejecting results in faster cycle times and reduced power train loads. Stability Ejecting the load without raising the body increases stability, allowing load dispersal on inclines, side slopes and in very soft underfoot conditions especially on landfill sites. Overhead Clearance The truck can eject in areas with reduced overhead clearance, such as around overhead lines or in tunneling and underground operations. Carry-Back The body design eliminates material sticking to the body, which increases productivity, improves fuel efficiency and lowers cost per ton. Body Reinforced body is made from thick high-yield, heat-treated Brinell hardened steel (Brinell 400 on the base and sides) that provides exceptional durability. For optimum durability and wear life, the ejector body is designed to work in applications where the material consists of rocks smaller than 152 mm (6 in) in diameter. Blade The ejector blade is made from high-strength steel and uses technology similar to that proven in Cat wheel tractorscrapers. Cylinder A four-stage, high-speed, double-acting cylinder is specifically designed for horizontal mounting and smooth load ejection. 8 Product Link Equipment manager is a secure and user-friendly application.

Long Service Intervals Long engine oil change and hydraulic oil change intervals lower maintenance costs and downtime. Wheel bearing adjustment is completely eliminated. Lube Points Lube points are grouped at the rear of the front frame and the front of the rear frame. Autolube is optional. Service Points Engine and transmission dipstick and fill caps, air and fuel filters and the fuel-priming pump are all mounted on the left side of the engine under the electrically raised hood.
