Excavators in different scenarios
As a multi-functional construction machinery, excavator has significant differences in its application and configuration in different scenarios. The following is an analysis of its typical applications in the three major fields of construction, mining and agriculture:
Construction projects
Core application
1. Foundation construction: excavation of foundation, basement and pile foundation holes, equipped with screw drill to achieve accurate hole formation
2. Earthwork: carry out large-scale earthwork transfer, and configure dozer shovel to achieve site leveling
3. Municipal operations: narrow arm models are used for trench excavation when laying underground pipe networks
4. Building demolition: controlled demolition with hydraulic shear and crushing hammer
Technical features:
l Commonly used 20-30 ton hydraulic excavator
l 360° rotating platform for complex site layout
l Optional rubber track to reduce damage to hardened pavement
l Equipped with intelligent control system to achieve millimeter-level operating accuracy
Mining
Core application
1. Ore mining and loading: cooperating with 300-ton mining truck for continuous loading
2. Step dressing: GPS positioning system is used to maintain the slope of mining surface
3. Crushing treatment: equipped with high-frequency crushing hammer to deal with large ores
4. Dump management: construction of anti-landslide platform and drainage system
Technical features:
l Mining excavator with more than 400 horsepower
l Enhanced boom and bucket tooth design (HB grade or above)
l Standard FOPS/ROPS protection structure
l Automatic lubrication system and heavy duty cooling device
l Remote monitoring system to prevent critical component failure
Agricultural production
Core application
1. Water conservancy construction : excavation of irrigation channels (depth 1.5-3 meters)
2. Land regulation: Laser leveling system is configured to achieve field leveling
3. Material handling: straw packing with wood grabber
4. Facility construction: construction of greenhouse foundation and septic tank of breeding farm
Technical features:
l Select compact equipment of 8-15 tons
l Variable gauge chassis suitable for field work
l Versatile quick change interface compatible with farm tools accessories
l Biodiesel compatible power system
l Anti-rust treatment for fertilizer corrosion
Scene comparison
Scene | Construction | Mining | Agricultural |
Operating Weight | 20-35t | 40-800t | 5-20t |
Task Cycle | 8-12h/day | 3 shifts in one day | Seasonal |
Spare Parts | Multiple genera | Fixed configuration Reinforcement bucket | Special farm implement |
Accuracy | ±5mm | centimetre-level | decimeter |
Maintenance Period | 250h | 500h | Seasonal |
Technological evolution trend
1. Electrification: Construction sites begin to use pure electric drive models (such as CAT 323EV)
2. Intelligence: mining scene popularization of unmanned mining system (5G remote control)
3. Modularity: Agricultural models have developed a detachable multi-functional tool box
Different scenarios have different requirements for the structural strength, working efficiency, control accuracy and maintenance cycle of excavators. Users need to consider the complexity of working conditions, return on investment cycle, and local environmental regulations when selecting a device supplier. It is recommended that you preferentially select a device supplier that has the ability to customize the excavator according to different scenarios.
