Large size bucket Heavy lift mode Easy Maintenance Excellent Reliability and Durability Shockless boom Replacement interval is extended for new hydraulic filter. See page 7. Switch selection reduces chassis vibration after sudden stops. the boom foot, improving hose life and safety. Swing priority mode Boom foot hoses are arranged under performance, are used for the hydraulic hoses. [. . . ] In addition, this machine is equipped with an automatic travel speed shifting system, which makes automatic Hi/Lo shifts. Heavy Lift Mode tank capacity (2750 ltr 726. 6 U. S. gal) Heavy Lift Mode Gives the operator 10% more lifting force on the boom when needed for handling rock or heavy lifting applications. Swing Priority Mode Excellent Swing Performance Twin-swing motor system of PC750-7 provides excellent swing performance on slope. Two Settings for the Boom Smooth mode provides easy operation for gathering blasted rock and scraping operations. When maximum digging force is needed, switch to power mode for more effective excavating. Boom raise EMMS (Equipment Management Monitoring System) 1. Monitor Function Controller monitors engine oil level, coolant temperature, battery charge air-filter restriction, etc. Maintenance Monitor Function informs replacement time of oil and filters on LCD when the replacement interval is reached. Trouble Data Memory Function stores machine abnormalities (error codes) in the monitor for effective trouble shooting. Smooth mode Power mode Swing Priority Setting The swing priority setting allows the operator to use the same easy motion for 180° loading as 90° loading operations. By altering the oil flow, this setting allows you to select either boom or swing as the priority for increased production. Selection ON OFF Result Oil flow to the swing motor is increased. 90°loading operations are most efficient. Shockless Boom Control The PC750-7 features a shockless valve (double-check slow return valve) that automatically reduces the amount of vibration present when operating the boom. Operator fatigue is reduced (which can improve safety and productivity), and spillage caused by vibration is prevented. Extend and retract Photo may include optional equipment. 4 5 PC750-7 HYDRAULIC EXCAVATOR RELIABILITY RELIABILITY FEATURES FEATURES Excellent Reliability and Durability Boom Foot Hoses The boom foot hoses are arranged under the boom foot to reduce hose bend during operation, extending hose life and improving operator safety. MAINTENANCE MAINTENANCE FEATURES FEATURES Easy Maintenance Komatsu designed the PC750-7 for easy service access. Heat-Resistant Wiring Heat-resistant wiring is utilized for the engine electric circuit and other major component circuits. Sturdy Undercarriage Guard The undercarriage is strengthened to provide excellent reliability and durability when working on rocky ground or blasted rock. Wide Catwalk (optional) Wide walkway for maintenance is provided around the engine and hydraulic components, allowing easy access to inspection and maintenance points. Divided Type Engine Cover The divided engine cover allows inspection points around the engine to be easily accessed. Motorized Grease Gun Equipped with Hose Reel (optional) Greasing is made easy with the electric motorized grease gun and indicator. Circuit Breaker With the circuit breaker, the machine can be easily restarted after repair. Grease can drum storage location O-Ring Face Seal The hydraulic hose seal method has been changed from a conventional taper seal to an O-ring seal. This provides improved sealing performance during vibration. Sturdy guards shield the travel motors and piping against damage from rocks. Reduced Maintenance Costs Hydraulic oil filter replacement is extended from 500 to 1000 hours. Grease gun The grease gun can be reached from ground level. Indicator High-pressure In-Line Filtration The PC750-7 has the most extensive filtration system available, providing in-line filters as standard equipment. An in-line filter in the outlet port of each main hydraulic pump reduces failures caused by contamination. Track roller guard (full length) (optional) DT-type connectors seal tight and have higher reliability. KOMTRAX® System (optional) The KOMTRAX system monitors machine condition, operating status, operating location, etc. , and provides timely notification of any machine problems. Since data is transmitted via satellite communication system, secure data communication is possible from any operating site including a quarry or a mine, further improving machine reliability. Thermal guards are placed around high-temperature parts of the engine and accessory drive. Large handrails (standard) and wide catwalk (optional) are provided around revolving frame for easier and safer access to engine and hydraulic components. Automatic Air Conditioner (optional) A 6, 900 kcal air conditioner is utilized. The bi-level control function keeps the operator's head and feet cool and warm respectively. This improved air flow function keeps the inside of the cab comfortable throughout the year.
