[. . . ] See page 5 3 PC450-7 H Y D R A U L I C E X C A V A T O R HYDRAULIC EXCAVATOR PC450-7 PRODUCTIVITY FEATURES High Production and Low Fuel Consumption High production and low fuel consumption are achieved through the following two operation modes: Active mode, with maximum engine output to handle large production, while keeping fuel consumption low; and Eco mode for light duty applications, which enables operation at a speed comparable to Active mode with even lower fuel consumption. The two modes, Active mode for handling "large production" and Eco mode for "low fuel consumption" have been significantly improved. Lateral Stability Substantially Improved Stability Improved lateral stability is achieved by increasing the counterweight (330kg 730lb) and improving the balance of the machine body. PC450 PC450LC 10% better* 22% better* *(comparison with current model) Large Lifting Capacity PC450-7's improved lateral stability increases lifting capacity. ACTIVE MODE This mode handles large production by providing powerful and speedy operation, and achieves economical efficiency by substantial reduction of fuel consumption. (Comparison with current model) Production (index) Fuel consumption (index) Fuel efficiency (index) Variable Track Gauge (optional) Lateral stability is significantly improved when operating with the gauge extended. Lateral stability is increased by 30% (compared with the fixed gauge of the current model). [. . . ] 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. Multi-Position Controls The multi-position, pressure proportional control levers allow the operator to work in comfort while maintaining precise control. A double-slide mechanism allows the seat and control levers to move together or independently, allowing the operator to position the controls for maximum productivity and comfort. Steps with non-skid sheet and large handrail provide antislip footing for added safety.

Hydraulic oil filter, engine oil, and engine oil filter element replacement intervals are significantly extended to reduce maintenance costs. PC450-7 500 500 5, 000 1, 000 Quarry Hydraulic Excavator The PC450-7 is a specially designed for heavy-duty applications. The PC450-7 has strengthened work equipment and reinforced body parts for use in severe job sites such as quarry and gravel gathering, etc. Fixed one-piece laminated front window glass The front window is New hydraulic oil filter fixed and uses laminated safety glass to prevent scattering of glass fragments when broken. Fixed Skylight and Sunshade EMMS (Equipment Management Monitoring System) Monitor Function Controller monitors engine oil level, coolant level, engine oil pressure, coolant temperature, battery charge and air cleaner clogging, etc. If the controller finds any abnormality, it is displayed on the LCD. Maintenance Function Monitor informs replacement time of oil and filters on LCD when the replacement interval is reached. Trouble Data Memory Function Monitor stores error codes for effective troubleshooting.

Work Equipment Lubrication Intervals Are Extended with OMRF Bushings The lubrication interval is greatly extended by using BMRC bushings on the boom foot and boom cylinder, OMRF bushing on the other work equipment, and CRHF on the arm end face. Also, resin shims are applied to prevent friction sound between end faces at the work equipment pin bracket. Heavy-Duty Boom Dent Preventing Plates Plate length increased 37% Deck Guard Easy Maintenance Easy removal and installation of the radiator (side-by-side cooling) Removal and installation of the radiator and oil cooler are made easier by locating them side-by-side. Heavy-Duty Arm Strengthened Revolving Frame Underguard Easy Access for Engine Inspection The engine oil check pipe, oil filler, and oil filter, etc. , are located on the left side of the engine. BMRC (Bata Matrix Reinforced Copper Alloy) CRHF (Carbide Reinforced Hard facing Ferrous Alloy) High-Capacity Air Cleaner High capacity air cleaner is comparable to that of larger machine. The air cleaner can extend air cleaner life during long-term operation and prevents early clogging and resulting power decrease.
