2. The chassis adopts rubber tracks, which are lightweight and can reduce the noise of the vehicle's walking mechanism. Reducing the vibration of the vehicle body can significantly reduce fuel consumption and can walk on urban roads without damaging the road surface.
3. The chassis comes with hydraulic high support legs, which can be used for leveling drilling rigs, loading and unloading vehicles, and can serve as auxiliary support during operation.
4. The use of 24V electric starting diesel engine reduces the labor intensity of the operator, especially in cold seasons when starting the diesel engine is difficult, which shows great superiority.
5. This machine is equipped with a Bw-160 mud pump, which has a large flow rate and pressure, and is easy to maintain and repair. Spare parts can be purchased conveniently from all over the country.
6. Optional installation of hydraulic pipe twisting machine (75-168mm) to improve work efficiency and reduce labor costs.
7. The available models are HW-160L/HW-190L/HW-230L.
