CWD-500B, a mini dump truck, has obvious advantages. It is small and flexible, and can easily shuttle through narrow sites, such as courtyards and small construction sites, and adapt to complex terrain. Easy to operate, quick to use, no need for complicated training. The self-unloading function is efficient, and the hydraulic device helps to unload quickly, saving manpower and time. There are many dynamic adaptation scenarios, whether it is carrying building materials, garden cleaning and transportation, or agricultural transportation, it can be competent. The crawler design enhances the passability, and the muddy and rugged road surface runs steadily, reducing the damage to the ground and reducing the maintenance cost. It is a practical and good helper for multi-scene operation.
