I. Product Description

ZE215E is a 20-ton class medium hydraulic excavator launched by Zoomlion, specially designed for efficient earthwork operations in diversified scenarios. With strong power, durability, and intelligent features, it performs excellently in heavy-duty operations such as mining, infrastructure construction, and municipal engineering. The advanced hydraulic system and ergonomic design make it a reliable choice for both large projects and fine operations.

II. Features

1. Powerful Performance

Engine: Equipped with Weichai WP6G220E33 (National III) engine, outputting 136kW at 2200rpm, suitable for high-intensity operations like mine gravel excavation and hard soil breaking.
Hydraulic System: Load-sensitive pump and electro-hydraulic proportional valve design ensure fast action response and smooth compound operation, increasing excavation efficiency by about 10%.

2. Durability and Reliability

Structural Strengthening: The boom and arm use high-strength low-alloy steel (yield strength ≥690MPa), and key welds are inspected by ultrasonic flaw detection, improving anti-fatigue performance by 20%.
Adaptive Cooling: Standard large radiator and intelligent temperature-controlled fan ensure stable operation in environments from -20°C to 45°C, adapting to high-temperature or cold regions.

3. Comfortable Operation

Cab: Equipped with a suspended seat, full-automatic air conditioning, and shock absorption device, with noise below 78dB (ISO standard) to reduce driver fatigue.
Vision Optimization: 7-inch color display integrates front and rear cameras, and the rearward design of the engine compartment enhances rear vision, reducing blind spots.

4. Convenient Maintenance

Centralized Maintenance: Filters and oil inspection ports are centralized on one side, shortening maintenance time by 30%; hydraulic oil replacement cycle is extended to 5,000 hours (industry average: 3,000 hours).
Intelligent Diagnosis: On-board computer real-time monitors parameters such as oil temperature and pressure, supporting fault self-diagnosis and remote upgrade.
