Used Howo Mining 371 hp Dump Trucks

Product Description

According to different classification methods, dump trucks can be divided into the following categories:
Classification by use: including ordinary dump trucks for road transportation and heavy dump trucks for non-road transportation. Heavy duty dump trucks are mainly used for loading and unloading operations in mining areas and large and medium-sized civil engineering projects.
According to the classification of loading quality: it can be divided into light dump trucks (loading quality below 3.5 tons), medium dump trucks (loading quality 4 tons to 8 tons) and heavy dump trucks (loading quality above 8 tons).
Classified by transmission type: it can be divided into three types: mechanical transmission, hydraulic mechanical transmission and electric transmission. Dump trucks with a load of less than 30 tons mainly use mechanical transmission, while heavy dump trucks with a load of more than 80 tons mostly use electric drive.
Classified according to the unloading method: there are various forms such as backward tilting type, side tilting type, three-side dumping type, bottom unloading type, and cargo box rising backward tilting type. Among them, the backward tilting type is the most widely used, while the side tilting type is suitable for occasions where the lane is narrow and the discharge direction is difficult to change. The container rises and tilts backwards, which is suitable for the occasions of stacking goods, changing the position of goods, and unloading goods at high places. Bottom discharge and three-side discharge are mainly used in a few special occasions.
According to the classification of dumping mechanism: it is divided into direct push dump truck and lever lift dump truck. The direct push type can be subdivided into single-cylinder type, double-cylinder type, multi-stage type, etc. Leverage can be subdivided into pre-leverage, post-leverage, and Chinese-leverage.
Classified according to the structure of the carriage: according to the structure of the fence, it is divided into one-side open type, three-side open type and no rear fence type (dustpan type).
According to the cross-sectional shape of the bottom plate, it is divided into rectangular type, ship bottom type and arc bottom type. Ordinary dump trucks are generally modified and designed on the basis of the second-class chassis of trucks. It is mainly composed of chassis, power transmission device, hydraulic dumping mechanism, sub-frame and special cargo box. Ordinary dump trucks with a total mass of less than 19 tons generally adopt FR4×2II chassis, that is, the layout of the front engine and rear axle drive. Dump trucks with a total mass of more than 19 tons mostly adopt the driving form of 6×4 or 6×2.
