Why is the 22-ton excavator the world’s most popular “golden tonnage”?

In the excavator market, the 22-ton class has long held an undisputed dominant position, hailed as the “golden tonnage” in the construction machinery field. Whether for global dealers or end-users, this tonnage is consistently the first choice. This is primarily determined by the perfect balance of performance, regulations, economy, and application scenarios.

Technical Analysis: Performance and Scale

Engine: The LG220 excavator uses a 110-130kW power system. This power output ensures the hydraulic system can maintain a bucket capacity of 0.8-1.2 cubic meters.

Dig Depth: The LG220’s standard digging depth is 6-7 meters, meeting the needs of 92% of common real estate and municipal operations.

Cross-section Design: Optimized internal reinforcing rib layout ensures uniform stress distribution and extends service life by 30%. The boom welding uses submerged arc welding + ultrasonic testing to ensure defect-free welds.

Weight Limitation: Most international transport regulations limit the total weight for standard flatbed transport to 30 tons. The LG220 (approximately 22.5 tons) can be transported using a standard 6×4 trailer without requiring an “overweight transport” permit.

Investment Recovery Period: Due to the high utilization rate of the LG220 in the rental market, its investment recovery period typically reaches the break-even point within 18-24 months.

Moderate Cost: The LG220 is competitively priced, with a relatively low investment threshold.

Function Expansion: Standard quick-change hose interfaces allow for rapid connection of various attachments such as hydraulic breakers and log grapples, enabling multi-purpose use. Common attachments include:

1. Hydraulic Breaker: The hydraulic breaker is the most common attachment for excavators, specifically designed for the most challenging demolition conditions.

2. Log Grapple: Equipped with a 360-degree hydraulic rotary motor, it can precisely grab, move, and stack timber.
