Why the LGMA LG220 Is the Ideal Choice for 22-Ton Class Excavators
In the heavy construction machinery sector, 22-ton class excavators have long been hailed as the “all-rounders” of the infrastructure construction site. Equipment in this weight class must handle both high-intensity excavation of large-scale earthworks and precision operations in municipal engineering projects. Shandong LGMA’s LG220 excavator resolves the common challenge of balancing “power redundancy and energy consumption” in heavy-duty operations typical of 22-ton models.
Powerful Output: The LGMA LG220 excavator offers a Cummins engine option with a rated power of up to 145 kW. High torque reserves ensure smooth and consistent power delivery when excavating hard soil or gravel.
Environmental Compliance: This powertrain meets the stringent Euro 5 and EPA Tier 4 international emission standards. This not only ensures the LG220 easily passes strict environmental inspections but also guarantees its resale value and high operational availability in global premium markets.
The reliability of a 22-ton machine depends not only on horsepower but also on the coordinated efficiency of its hydraulic system. By integrating world-class hydraulic components, the LG220 has established a highly efficient power transmission path:
Hydraulic Pump: Ensures the system delivers high-pressure, high-flow output, effectively extending the maintenance intervals of the hydraulic system.
Control Valves: Provide the operator with “surgical-precision” control feedback. Millisecond-level response logic enables the LG220 to demonstrate exceptional motion coordination during fine grading operations.
Rotary Motor: Further optimizes the machine’s swing stability on complex slopes or uneven terrain.
In actual construction, earthmoving output per unit of time is the core metric for evaluating a machine’s value.
Deep Digging and Wide Coverage: The LG220 has an operating weight of 22.6 tons and comes standard with a 1.0 m³ high-capacity bucket. It offers a maximum digging depth of 6,625 mm and a maximum working radius of 9,910 mm. This extensive working envelope significantly reduces time lost due to frequent machine repositioning and movement.
Energy Storage Advantages: Equipped with a 350-liter fuel tank and a 240-liter hydraulic oil tank. The large-capacity tank design not only ensures the machine’s sustained operational capability during high-intensity work seasons but also reduces the frequency of on-site refueling, thereby improving the return on investment per working hour.
Frequently Asked Questions
Q: For which specific working conditions is the 22-ton LG220 suitable?
A: The LG220 is a typical all-purpose model. With its powerful 145 kW engine and 1.0 m³ bucket configuration, it efficiently handles large-scale transportation infrastructure projects, deep foundation pit excavation, mining support operations, and large-area site grading tasks.
Q: How does the LG220 perform in terms of fuel efficiency?
A: The LG220 features “on-demand flow distribution.” During light-load operations or swing movements, the system automatically adjusts power output, significantly reducing fuel consumption while maintaining high productivity.
Summary
In today’s market, where high availability, strong resale value, and low operational risk are paramount, the LG220 excavator from LGMA offers global contractors a sound investment solution thanks to its robust manufacturing processes and international technical standards.
