[0002] Muck trucks, also known as soil trucks or slag trucks, do not refer to a specific type of vehicle, but rather to trucks used to transport construction waste such as sand and gravel. Muck trucks are mainly used to transport slag, sand and gravel generated at construction sites, and are an indispensable part of urban construction. Common muck trucks include large dump trucks, Bumblebees, etc., most of which are large load-bearing trucks.
[0003] Muck trucks have a large load capacity, and the load capacity varies depending on the model. Generally speaking, a larger muck truck can carry about 26 to 27 cubic meters of materials, while a smaller muck truck can carry about 20 to 22 cubic meters. With the development of cities and the improvement of environmental protection requirements, in order to avoid secondary pollution to the environment caused by leakage and dust during the transportation of urban muck trucks, the box of the muck truck is generally equipped with a canopy mechanism.
