MWD2.0 mining crawler excavator is a 2-ton mini excavator specially designed for underground mining, small engineering, agricultural and forestry operation scenarios. With four core advantages of MA mining safety certification, explosion-proof design, hydraulic precise control and high trafficability, it has become the mainstream mini engineering equipment for overseas mining, municipal, agricultural and forestry industries.
The overall structure is compact, and the overall dimensions are suitable for operation in narrow spaces. The total weight of the machine is 2000kg, the bucket capacity is 0.1m³. It is equipped with a Changchai 4L88 China Stage 2 engine with a rated power of 18.5kW and a rated speed of 2200rpm. It has sufficient power and stable fuel consumption, meeting the emission requirements of many countries. The working end has excellent performance: maximum digging depth 2400mm, maximum digging height 3100mm, maximum unloading height 2100mm, maximum digging radius 2800mm. It can easily complete foundation pit digging, earth moving, material loading and unloading, orchard ditching and other operations. The rotation speed is 11rpm, and the operation cycle rhythm is smooth, which greatly improves the construction efficiency.
The walking system adopts a crawler structure with a crawler grounding length of 1400mm and a crawler width of 180mm. The ground pressure is low, and the damage to the ground is small. It is suitable for sensitive ground operations such as orchards, greenhouses and indoors. The minimum ground clearance is 200mm, the maximum driving speed is 2.5km/h, and the maximum climbing capacity is 30°. It can smoothly pass through underground mines, rough construction roads and fields, and its trafficability is far better than that of wheeled equipment of the same level.
The control system adopts hydraulic pilot design, which is easy and precise to operate. It can realize stepless adjustment of boom, arm, bucket and rotation movements, and even novices can get started quickly. The hydraulic system has a working pressure of 16MPa and a flow rate of 40L/min, with quick response and no impact jitter, ensuring excellent operation stability. The equipment is equipped with MA mining safety certification as standard, and the explosion-proof design is suitable for flammable and explosive environments in underground mines. It is also equipped with multiple safety protection devices to fully guarantee the safety of operators.
The core components of the machine are made of high-quality accessories, with low failure rate and easy maintenance. It can be customized according to customer needs for buckets, attachments and appearance. It supports disassembly and packing for container transportation, adapting to global sea and land logistics needs. We can provide original spare parts, multilingual operation manuals and overseas localized after-sales support, making it a cost-effective preferred equipment for overseas mining, municipal, agricultural and forestry projects.
