The Komatsu 55 excavator is a small or mini excavator known for its efficient operation and durability, suitable for a variety of earthwork and infrastructure construction scenarios. The following is a comprehensive description:

1. Basic parameters

Power system

Engine power: about 50-55 horsepower (37-54.3 kW), equipped with Komatsu inline four-cylinder water-cooled engine, supports automatic idle shutdown function, and takes into account power output and fuel economy.

Hydraulic system: hydraulic flow 128.2 liters/minute, working pressure 28 MPa, to ensure efficient operation response.

Weight and size

Machine weight: about 5.5 tons (may fluctuate in the range of 4850-5500 kg under different configurations).

Travel speed: 2.5-4.5 kilometers/hour, rotation speed 8.8-12 revolutions/minute, to adapt to different terrain requirements.

Excavation performance

Maximum excavation depth: 3.38-4.32 meters, depending on the configuration (such as boom length).

Bucket capacity: 0.13-0.28 cubic meters, suitable for small and medium-sized earthwork operations.

Traction and climbing ability: Maximum traction 37-42.8 kN, maximum climbing grade 30 degrees, adaptable to complex terrain.

2. Performance characteristics

Structural design

The boom and dipper are reinforced, and the bucket is optimized to improve durability under high-intensity operations.

Low ground pressure (about 34.1 kPa), reducing pressure loss on soft ground.

Intelligence and operation experience

Equipped with intelligent working mode selection function, the operation efficiency can be adjusted according to the working conditions.

The cab layout is simple and maintenance is convenient. Some models may be equipped with LCD monitors to improve the convenience of operation.

Environmental protection and economy

The fuel tank capacity is 80 liters and the hydraulic oil tank is 60 liters, which supports long-term continuous operation.

Low fuel consumption design, combined with automatic idling function, reduces the cost of use.

3. Applicable scenarios

Mining and heavy-duty operations: The solid structure is suitable for high-intensity mining excavation.

Municipal and infrastructure construction: The body is relatively compact (such as the maximum excavation radius of 5.76-6.7 meters), suitable for narrow urban space operations.

Agriculture and land leveling: Suitable for small and medium-sized earthwork handling and ditch excavation.

IV. Market positioning and comparison

Comparison with models of the same brand: Compared with Komatsu 60, the 55 model is lighter and more economical, suitable for scenes with limited budgets or low operating intensity.

Comparison of competitive products: Compared with models such as Volvo EC55D, Komatsu 55 has more advantages in power output and structural strength, but its intelligent configuration is slightly inferior.
