PC28UU-1 Komatsu excavator specs & dimensions (1984 - 1991)

Working range Max digging height PC28UU-1: 4800 mm (15'9) PC50UUU-1: 6180 mm (20'3") Max dumping height PC28UU-1 : 34450 mm With tough Komatsu diesel engines, they feature bucket digging forces of 2140 kg (4,720 lb) for the PC28UU and 3500 kg 0.720 lb) for the PC50UU, which means efficient excavation even in hard terrain. And their large bucket capacities further increase productivity. They also have large knives with reinforced cutting edge for smooth filling and levelling. Unique low noise design The PC2BU U/PC50U U has been designed to minimize noise; it includes noise-absorbing materials, a machine cab and a suction fan. This enables the PC2BU U / PC50U u to efficiently perform any work without disturbing its surroundings, even at night in the housing area.

Machine PC28U.1 PC50U-1 Lever stroke 100o/o Smooth swing action Swing action takes place with a control valve operated rocking system. Stopping and starting is smooth, precise and firm. This not only minimises operator fatigue but also increases productivity. Hard, productive dozer blade This hard-designed blade is ideal for filling and levelling. The advanced control valve mechanism Provides smooth, simultaneous blade movement and machine travel. Safe lock lever By tightening the lock lever on the side of the lever console all work levers are locked. In this way any front and right / post movements of working equipment are stopped. This prevents misoperation of work attachments in case of downtime or when removing the seat. Fuel injection pump Fuet feed pump Dust seal Automatic air bleedout Air removal from the fuel lines automatically occurs after turning off the initial engine. Extended service Unique dust tightness prevent dirt entry into the pin-to bus singing for longer bushing life 1 Tough undercarriage is built to be used as an undercarriage frame; one tweezer ow lubricated by means of mechanically retractable hydraulic shock absorbance (for example)

Control arrangement reduces operator fatigue Since all control elements, counters and gauges are ergonomically leached, operator fatigue greatly decreases. In addition, the controls provide quick response and sensitive control of work equipment. The boom offset mechanism is controlled by a pedal operation. Operating device control lever & boom offset pedal can be locked to prevent inadvertent movement. With ample working range and excellent visibility, operators can perform safer work. PC28U-1 PC50UU-1 Time-saving and cost saving maintenance The operator can release the machine cover lock from inside. And fully opened machine cover allows fast access to the engine and hydraulic equipment for rapid checks and repairs. This minimises servicing time. PC28UU.1 PC50UU-1 PC50U
