The mining crawler flatbed truck is mainly used in underground mining operations. It serves as a transport vehicle for equipment and materials in underground roadways, and is currently applied in mines to convey large mining equipment such as shearers and heavy hydraulic supports. Featuring a simple structure, easy fabrication, rugged durability and convenient maintenance, it is widely adopted in underground mines.

Powered by compressed air, the mining crawler flatbed truck achieves self-propulsion via its crawler tracks. The overall vehicle length is less than 3 meters with a height of 0.6 meters. Light and small cargo can be directly loaded by manual lifting. Boasting a large load capacity, high travel speed, simple structure, flexible operation and easy maintenance, this transporter has become essential equipment for underground coal mine transportation.

The crawler flatbed truck adopts compressed gas as its power source. Manufacturers equip it with a high-efficiency, high-power pneumatic pump to drive the electro-hydraulic pump, which in turn actuates the crawler lifting mechanism to realize self-propulsion. The entire vehicle relies solely on a ventilation air hose as its power supply to perform all functions. Compact and lightweight, it can meet the demands of cargo transportation under complex roadway conditions in coal tunnels. With an air-to-hydraulic working principle, no electrical wiring is required, delivering explosion-proof safety and simplified maintenance. It also eliminates the drawbacks of pure pneumatic systems, namely unstable power output and uncontrollable driving force, enabling smoother, more reliable operation and greater power performance.

The transporter consists of an air purifier, pneumatic triplet, crawler assembly, air motor, pneumatic diaphragm pump station, crawler travel regulating valve, oil tank, upper flatbed, partition, rope hanging holes and protective cover. The air purifier effectively filters impurities from the air source; the pneumatic triplet provides sufficient lubrication for the motor to extend service life. The oil tank and frame are welded as an integrated unit and installed inside the crawler assembly to save space efficiently. Rope hanging holes are directly machined on the flatbed, saving space while facilitating cargo binding during transportation. An air motor drives the gear pump for stable and reliable operation. The partition protects the vehicle’s functional components and operators. The crawler regulating valve adopts a spring automatic reset design; adjusting the spool angle controls the travel speed of the crawler.

This solution can satisfy your company’s application requirements:

1. The loading flatbed of the transporter measures 2 m in length and 0.9 m in width, with a ground clearance of only 0.5 m.
2. The transporter can carry cargo on slopes ranging from -20° to +20°.
3. The rated load capacity of the transporter is 3.0 tons.
