Self-unloading means to unload the goods vehicle itself by hydraulic or mechanical lift, also known as dump trucks. It consists of a car chassis, a hydraulic lifting mechanism, a cargo box and a power take-off device. Because the loading compartment can automatically tip and discharge at a certain angle, the time and labor of the unloading can be greatly saved, the transportation cycle can be shortened, the production efficiency can be improved, and the transportation cost can be reduced. This is a common transportation vehicle. Chassis When choosing the chassis, it is generally considered in terms of economic benefits, such as chassis price, loading quality, overload capacity, fuel consumption per 100 km, fuel consumption per 100 km, etc. In addition, the user also needs to consider the following parameters of the chassis: ( 1 ) The height of the chassis frame above the ground. General 6x4 chassis frame above the ground from the height of 1050 ~ 1200 . The higher the value is, the higher the vehicle's center of gravity is and the easier it will be to roll over. The factors affecting this value are mainly the diameter of the tire, the arrangement of the suspension and the height of the main frame section; ( 2 ) The rear suspension of the chassis. This value too much effect on self-unloading lift stability, rollover accidents caused by lifting. This value generally (except from rollover unloading) between 500-1100; ( 3 ) The vehicle is reasonable and reliable to use. Tops Currently self-unloading modified manufacturer cohabitation, select manufacturers equally important than the choice of select products from unloading. In addition to look at the product, but also the ability to understand the manufacturers of equipment, self-unloading jacket design, technology and equipment maturity, service commitments, whether to buy accessories and so on. ( 1 ) Cars The choice of compartments is mainly from the use of materials, the choice of 16Mn material is better than ordinary A3 material strength, but the cost is also high. Appropriately increase the local thickness according to the different cargoes to meet the requirements. ( 2 ) Selection of lifting mechanism In order to reduce the weight of the carriage, some carriages can be made of aluminum alloy or high-strength materials to reduce the weight and increase the load. 1, a general purpose selected from the unloading recommended tripod Amplified lifting mechanism, the structure of almost 40 years, technology is relatively mature, the length of the cabin for 4 to 6 m from unloading; 2. Reasonable layout, the stress of each component will not exceed the bearing capacity of the components, and the system oil pressure is small to ensure the service life of each seal; 3 , choose a high quality hydraulic cylinder. Unloading the hydraulic cylinder is lifted from the power unit, to select a quality assurance of products; 4, the carriage length is greater than 6 meters from the hopper car is generally used in a multistage lifting cylinder top-front structure; 5, the lifting mechanism is generally used wheelbase cylinder 3 to 4 meters from the unloading. ( 3 ) Several issues to pay attention to when uploading and selecting 1. Buckets must be used to transport large items; 2. When the length of the carriage is more than 5.4 meters, special attention should be paid to the height of the center of gravity of the carriage and the lifting stability; 3 , can not use the coal transport vehicles to transport earth and stone. Generally, the height of the carriages of special vehicles for coal transportation is 1.6 to 1.9 meters . How long these types of vehicles are designed is based on lightweight goods (specific gravity less than 1.2 ), which may cause poor lifting stability when transporting earth and stone. Serious Can cause lifting accidents; 4. Do not use the bucket car to transport mud, clay and other viscous goods. The structure of the bucket car makes it more difficult to remove the viscous goods. 5, the self-declared by the manufacturer to keep the selection unloading transport of iron ore fines, iron ores best choice selection vehicles; 6. When used for paving asphalt transportation, the lifting mechanism requires a slow descending device. Self-unloading choice or to choose the right type based on the specific application, because from unloading in general are more difficult operating environment, select quality and excellent reputation of the brand is particularly important, a good tool for heavy trucks is high attendance money.
