Lanxiang mainly manufactures excavation production line including drilling, loading, hauling and conveying equipment. Our machines are widely used in coal mine, non-coal mine, railway, highway, water, power and other industries. In recent years, we have been engaged in the development of mechanical type and hydraulic type large scale shuttle mine car. Our patented products include TZ series coaxial type concrete conveying tank car, NTZ8 internal combustion rail type concrete conveying tank car, LXSL80 concrete screw conveyor, KZ8～16 cubic side dump wagon, crawler rock mucking loader for inclined shaft (>16º) construction in coal mine, WDZL312 crawler rock mucking loader for large cross section tunnels, etc.

Description of Main Products
1. Mucking Loader (Mucking Machine/Haggloader)
Mucking loader primary features small size, high flexibility, large driving force, stable performance and long service life. It is an ideal equipment for small cross section tunneling.
Note:
High-end mucking machine is configured with quick coupler to realize fast switch between bucket and quartering hammer within one minute.
(1) Innovation 1
With respect to physical design, mucking machine has integrated functions of excavator, loader and bulldozer, so it can significantly improve working efficiency. It requires no redundant works, such as moving back and forward, so it can save power. Since the innovative design of our equipment helps avoid a number of unnecessary work, it reduces actual working power by 27.8%. For example, ZWY 180 excavator (75kW) possesses the equal loading capacity of other excavators (108kW).
(2) Innovation 2
Our mucking machine can climb slope with gradient reaches up to 36º. So far, ICT312 tunnel mucking loader manufactured by Terex can climb slope with gradient no more than 16º. Now, we have developed a patented machine “arch bridge crawler rock mucking loader” (Patent No.: -ZL 2007 2 0177135.0). By improving the traveling mechanism of crawler, gradeability can increase to 42º.
(3) Innovation 3
The existing technology can keep the transported rock ballast from tumbling during transport on slope (gradient is no more than 32º). Besides, it can’t convey mud water, mortar and other fluids. With the increase of gradient, the transport capacity of the equipment will be lowered. Therefore, we designed another patented equipment “combined scraper conveyor” (Patented No.: -ZL 2009 1 0115993.6) that solved the problem of material tumbling. It can also transport mud water, mortar and other fluids. In addition, the maximum gradient for this equipment reaches up to 45º.
(4) Innovation 4
There is no hydraulic equipment configured with constant temperature system currently. But we have been engaged in studying constant temperature technology in hydraulic system for a long time and achieved huge success. Our innovated equipment is configured with main oil tank, auxiliary oil tank and temperature control valve. The hydraulic oil in main oil tank and auxiliary tank can swap automatically according to different temperature pressure, so that the hydraulic oil temperature reaches set standard. If the machine works for a long time and the temperature surpasses the set standard, the auxiliary tank will start the cooling system to reduce oil temperature in the auxiliary tank. This helps to extend the service life of hydraulic components as well as improve equipment reliability.
(5) Innovation 5
Our equipment has integrated optical, mechanical, electric and hydraulic technologies. Our products have already achieved excellent performance in energy saving, safety, environment protection, efficiency and automation.

2. Mine Shuttle Car
Shuttle mine car is a highly-efficient and automatic transporting equipment. It needs to be towed, so it is usually applied together with traction locomotive. This shuttle car is suitable for indoor and outdoor rail transport, such as tunnel, mine and other engineering projects.
Note: the electric locomotive can only be used at altitudes lower than 1200 m and temperature between -20℃ and 40℃.

3. Concrete Mixer and Conveyor Truck
Conveyor truck is designed to transport concrete from the mixing place to construction site. It is suited to transport concrete in railway tunnels, national defense construction, water conservancy projects, underground mines, etc. In general roadway transport, the truck must be pulled with an 8T battery car. In inclined shaft (≤25º) transport, no matter hauling up or down, the truck should be pulled with a winch. We have concrete mixers and conveyor trucks with different capacities, including 4m³, 6m³ and 8m³. Both explosion-proof and non-explosion-proof concrete truck are available.
