The ZDL204DD underground loader is designed to work with mining trucks in underground excavation and mining operations. Its 2 m³ bucket loads ore and other materials efficiently, supporting a practical load-haul-dump workflow for trackless mining.
The ZDL204DD combines a 4,000 kg rated load, 2 m³ SAE bucket, and articulated underground-loader layout for loading broken ore and other materials. It is intended to feed underground trucks and support efficient trackless mining cycles.
Sized for underground loading work with a 2.5 m × 2.5 m minimum tunnel section, a central articulated frame, and a minimum outside turning radius of 5.3 m.
The 4,000 kg rated load and 2 m³ SAE bucket support ore and waste-rock loading into underground haul trucks.
The DEUTZ F6L914 engine, DANA power-shift transmission and C272 torque converter provide a proven diesel powertrain for underground haulage and loading cycles.
Wet multi-disc service braking, spring-applied hydraulic-release parking braking, and accessible hydraulic components support routine inspection and controlled maintenance.

Before entering the mine, operators must wear a safety helmet, carry a self-rescue device, and use a mining lamp. Inspect the loader regularly and correct hazards promptly. Never maintain the machine while it is running; relieve hydraulic pressure before repairs. Before welding or cutting, confirm that no flammable or explosive material is present, and avoid contact with the hot exhaust pipe.
Application conditions: firm roof; outside turning radius ≥5.3 m; road slope ≤14°; adequate ventilation and drainage. Ambient temperature -5°C to 40°C, relative humidity at 25°C ≤85%, and altitude ≤1,000 m; power derating is required above 1,000 m. Fuel sulfur content must not exceed 0.2%. Do not use the loader where flammable or explosive gases, gas, or coal dust are present.

What is the ZDL204DD underground loader used for?
It loads ore and other materials in underground excavation and mining operations, typically working with underground mining trucks in a trackless mining workflow.
How do I choose the bucket for this underground loader?
Start with material density, fragmentation, bucket fill target, loading height, and the receiving truck or hopper. Zongda Mining should confirm the bucket and breakout requirements against the selected configuration.
Can the ZDL204DD work in a narrow tunnel?
It is specified for tunnel sections of at least 2.5 m × 2.5 m, with a minimum outside turning radius of 5.3 m. Confirm the complete clearance and turning study before ordering.
What information is needed for a quotation?
Send the mine application, tunnel size, material type, desired capacity, ramp and haul conditions, power and ventilation limits, destination country, and delivery schedule.
Can you provide spare parts and technical support?
Ask for the model-specific spare-parts list, recommended consumables, service documentation, commissioning scope, and available after-sales support for your destination.
Is this model available with different configurations?
Configuration availability must be confirmed for the order. Discuss the bucket, cab or canopy, power unit, braking, tires, lighting, fire-suppression, and other site requirements before quotation.
