Used komatsu PC220-6Medium Excavator Komatsu Hydraulic Excavator

The Komatsu 220-6 excavator is a medium-sized crawler hydraulic excavator produced by Komatsu, which is mainly suitable for earthwork, building demolition, road construction and other scenarios. The following is a detailed description:

1. Basic parameters

Power and weight

Rated power:, the standard version is 93 kW (about 124 horsepower), and another version mentions a net power of 119.3 kW (about 160 horsepower).

Working weight of the whole machine: 22.3 tons1 or 22,180 kg.

Engine model: Komatsu SA6D102E engine, fuel tank capacity 340 liters2.

Operation capacity

Bucket capacity: standard configuration 0.8 cubic meters, some configurations can be selected 0.72-1.3 cubic meters.

Maximum digging depth: 6.18 meters, another data is 5.88 meters (due to different arm lengths).

Digging force: The maximum digging force of the bucket is 139.1 kN.

Travel speed: 2.8-5.5 km/h, climbing ability up to 35 degrees.

2. Technical features

Hydraulic system

Adopt Komatsu's unique closed-center load-sensing hydraulic system to improve operation stability and accuracy, suitable for high-frequency operations (such as loading and dumping soil).

Some users reported that their hydraulic system may have oil temperature rise problems during high-intensity crushing operations, requiring intermittent use and enhanced heat dissipation management.

Power and fuel efficiency

Equipped with electronic fuel injection technology, optimize fuel injection volume and timing control, taking into account power output and energy saving and environmental protection.

Second-hand equipment data shows that the original Japanese engine still maintains good performance after 1,200 hours of work, and has better fuel economy.

Structure and durability

The body is made of high-strength steel and reinforced chassis design to adapt to harsh working conditions. The main wear parts for long-term use are chains and hydraulic pipes.

Easy maintenance, key components (such as filters and hydraulic pumps) have obvious inspection points, which support quick replacement.

3. Operation experience and configuration

Cab design

Equipped with air conditioning, adjustable seats and low noise design (about 67 decibels), the operating environment is comfortable.

Some models can be equipped with optional rearview cameras and 7-inch LCD screens to improve operation safety and information visualization.

Multi-functional adaptability

Supports accessories such as breakers and ripper, but pay attention to the load limit of the hydraulic system.

Optional bucket capacities (0.72-1.3 cubic meters) to meet diverse working conditions
