20-ton Class Medium Hydraulic Excavator For Mining, Infrastructure Construction, And Municipal Engineering

The ZE215E is a 20-ton class medium hydraulic excavator from Zoomlion, engineered for efficient earthwork operations across diverse applications. Combining robust power, exceptional durability, and intelligent features, this excavator excels in demanding operations including mining, infrastructure development, and municipal projects. Its advanced hydraulic system and ergonomic design ensure reliable performance for both large-scale projects and precision tasks.

• Engine: Weichai WP6G220E33 (National III) engine delivers 136kW at 2200rpm, optimized for high-intensity operations including mine gravel excavation and hard soil breaking.
• Hydraulic System: Load-sensitive pump and electro-hydraulic proportional valve design provide rapid response and smooth compound operation, boosting excavation efficiency by approximately 10%.

• Structural Strength: Boom and arm constructed from high-strength low-alloy steel (yield strength ≥690MPa) with ultrasonic flaw detection on critical welds, enhancing anti-fatigue performance by 20%.
• Adaptive Cooling: Large radiator with intelligent temperature-controlled fan maintains stable operation in extreme temperatures from -20°C to 45°C.

• Cab Design: Features suspended seat, automatic climate control, and shock absorption with noise levels below 78dB (ISO standard) to minimize operator fatigue.
• Visibility: 7-inch color display integrates front/rear cameras, while rearward engine compartment design reduces blind spots.

• Centralized Access: Filters and inspection ports grouped on one side reduce maintenance time by 30%, with hydraulic oil replacement extended to 5,000 hours (industry average: 3,000 hours).
• Smart Diagnostics: On-board computer monitors oil temperature, pressure, and other parameters in real-time, supporting fault diagnosis and remote upgrades.

• Mining & Quarries: Ore loading, bench excavation, and road construction in heavy-duty conditions
• Municipal Engineering: Urban pipeline installation, river dredging, and construction waste management
• Infrastructure: Highway/railway subgrade excavation and bridge foundation work
• Agriculture & Water: Farmland transformation, reservoir dam reinforcement, and irrigation channel excavation
