I. Basic Overview
The Komatsu PC220-8 is a 22-ton tracked backhoe hydraulic excavator. It uses a conventional power system and is suitable for general engineering operations, covering earthwork excavation, foundation construction, material handling, and other tasks. The machine has a working weight of 23,100 kg and a standard bucket capacity of 1.0 m³, offering wide applicability and high efficiency in the construction industry.
II. Core Component Parameters
(I) Engine System
It is equipped with a Komatsu SAA6D107E-1 engine. This engine is water-cooled, 4-stroke, direct-injection, and features turbocharging and aftercooling technology, meeting the 2006 EPA/Tier 3 and EU IIIA emission standards. The engine has a rated speed of 2000 rpm, a displacement of 6.69L, and a maximum output power of 125kW (170PS), providing strong power and excellent fuel economy, ensuring reliable power support for continuous and stable operation.
(II) Hydraulic System
A dual-variable plunger main pump is used, with a maximum flow rate of 439 L/min, ensuring efficient and smooth power transmission during operation. The travel hydraulic circuit is set to a pressure of 37.3 MPa, and the slewing hydraulic circuit is set to a pressure of 28.9 MPa. This precise pressure configuration provides excellent maneuverability and power output during travel, slewing, and digging operations, enabling it to meet the high-intensity demands of complex working environments.
III. Overall Dimensions and Operating Range
(I) Overall Dimensions
In transport mode, the overall dimensions are 9885 mm (length), 2980 mm (width), and 3055 mm (height). The track gauge is 2380 mm, the track shoe width is 600 mm, the minimum ground clearance is 440 mm, and the rear slewing radius is 2905 mm. This compact and reasonable design ensures both stability during operation and good maneuverability during transport and relocation in confined spaces.
(II) Operating Scope
Excavation Height: Maximum excavation height up to 10000mm, easily enabling high-rise building foundation construction, high-altitude material loading and unloading, and other operations.
Unloading Height: Maximum unloading height of 7035mm, compatible with various transport vehicle sizes, improving material transfer efficiency.
Excavation Depth: Maximum excavation depth of 6920mm, maximum vertical excavation depth of 6010mm, meeting the needs of deep foundation pit excavation, river dredging, and other deep operations.
Excavation Radius: Maximum excavation radius of 10180mm, maximum ground-level excavation radius of 10020mm, providing a wide operating coverage area, reducing frequent equipment movement, and improving overall operational efficiency.
IV. Performance Parameters
(I) Travel Performance
Features three travel speeds: high speed up to 5.5km/h, medium speed 4.2km/h, and low speed 3.1km/h. Speed can be flexibly switched according to the work site and relocation needs. High-speed mode can be selected for long-distance relocation to save time, while low-speed mode ensures stability and precise control during operation.
(II) Digging Force
The maximum digging force of the bucket is 17500 kgf (approximately 172 kN), and the maximum digging force of the boom is 13200 kgf (approximately 129 kN). This powerful digging force allows the equipment to maintain high digging efficiency even when facing hard soil and rock.
(III) Slewing Performance
The slewing speed reaches 11.7 rpm. The fast and smooth slewing action effectively shortens the work cycle time and improves the overall operating rhythm of the equipment.
V. Oil Capacity Parameters
The fuel tank capacity is 400L. The large-capacity fuel tank reduces the frequency of refueling during equipment operation, ensuring long-term continuous operation.
The hydraulic oil tank capacity is 135L, providing sufficient hydraulic oil reserves for the hydraulic system and maintaining stable system operation.
The engine oil change rate is 23.1L, and the coolant capacity is 19.8L. This reasonable oil capacity configuration reduces the frequency and cost of equipment maintenance.
