Description
We are excited to offer this professionally reconditioned 1988 Komatsu PC38UU mini excavator, which has an operating weight of 3,945 Kg (8,699 pounds) and only 3,266 hours of usage. The machine is in excellent running condition, as demonstrated by our transparent photos and video. The machine is powered by a Yanmar diesel engine (3D84-1GA) with a capacity of 30.0 HP. Additionally, this unit has been modified to operate with Caterpillar (S.A.E) control pattern by default. Japanese Komatsu control pattern can also be selected via a built-in quick shifter.
The mini excavator has undergone thorough servicing, including a replacement of hydraulic fluids, engine oils, coolant with antifreeze, and air, fuel, and oil filters. We have also made several upgrades, including a new hydraulic thumb controlled by a foot pedal, a new water-resistant seat and seat belt, a new starting battery, a new LED headlight, new bucket teeth, new decals, and a bright Caterpillar-yellow paint job. The unit has been fumigated and steam cleaned in accordance with U.S. CBP import requirements. This machine also comes with a spare ignition key, spare bucket teeth, spare filters, and a full set of operations & part manuals.
Product Features
This model is highly sought-after for its two-piece offset boom, which is ideal for working in tight spaces with limited swing. When working in a narrow alley, the boom can be knuckled off to the right or left, allowing the machine to dig in line with one of the tracks next to a structure. With its 1610-mm (5' 3") upper body, 1840-mm (6' 0") overall width, and a tail swing radius of 900 mm (2' 11"), this unit is qualified as a zero-tail swing machine.
Japanese ingenuity has been applied to this model by using sound-absorbing material in various parts of the machine to achieve low noise performance comparable to that of a passenger car. This makes it well-suited for night work and urban areas, such as schools and hospitals, with a noise level rated at 57 dBA @ 30 meters (98'5") and 68 dBA @ 7 meters (23'0"). To the operator's ears, noise exposure is rated at only 78 dBA.
