The 30CBM 40CBM cement bulk tanker semi trailer mainly uses the horizontal structure, which is mainly used for the transportation of bulk cement, fly ash, expansion agent, lime cement bulk and other cement bulky materials in China, and is the main force of the cement bulk tank semi-trailer. It has an absolute market share in the industry. The average output of cement bulk tank semi-displacement trucks in the past couple of years is countless, but it fluctuates greatly with the influence of national policies and infrastructure projects. It has reached the highest peak of annual production.
Tank Body of 30CBM 40CBM Cement Bulk Tanker
There are mainly two types of structure to the tank body of 30CBM 40CBM cement bulk tanker semi trailer. One is the single V type tank body, also known as the single compartment structure, while the other is the double V type, also known as the double compartment structure. A gas chamber structure and a fluidized bed are arranged inside the tank body, which are used to fluidize the materials loaded in the sealed tank by means of compressed gas.
General Specification of 30CBM 40CBM Cement Bulk Tanker
Dimension and Structure of Tank Body
The rapid development of horizontal cement bulk tank semi-trailers began in the early part of this century. With the increase of national infrastructure and the influence of policies, 30CBM 40CBM cement bulk tanker semi trailers appeared a peak in production. The production of cement bulk tank semi-trailers have improved dramatically. Horizontal cement bulk tank semi-trailer is divided into horizontal single compartment, double compartment, and three compartment cement bulk tank semi-trailer according to the structure. Due to the intensified efforts to control excess quantity and weight during transportation in recent years, the horizontal cement bulk tank semi-trailers currently on the market are mainly single and double compartment semi-trailers. The horizontal three-storage cement bulk tank semi-trailer has become a historical "Super Big Cement bulk tanker"
Frame (Chassis) Technology
The structure of the 30CBM 40CBM cement bulk tank semi-trailer frame shall meet the requirements of GB/T 23336 "General Technical Requirements for Semi-trailers", also known as GB/T 20070.
The requirements of "Mechanical Connection Interchangeability between Road Vehicle Tractors and Semi-trailers", etc., can meet the requirements of the designed horizontal cement bulk tank semi-trailer frame (chassis) to meet the versatility of semi-trailers and the compatibility with semi-trailer tractors. In order to realize the light weight of the vehicle, the frame main beam of the horizontal cement bulk tank semi-trailer meets the basic performance, and other areas are close to the tank body, and the width of the narrowest part of the web can be only 70mm according to customer’s requirement. At the same time, at the higher part of the web Quantitative holes are cut to minimize the mass of the frame. From the design calculation, CAE analysis and market verification, the stress is concentrated at the front end of the frame legs, the V-shaped bottom, and the front bracket, which is easy to cause the corresponding frame to crack and the tank to tear. Therefore, it is necessary to strengthen the rigidity by welding the reinforcement web at the corresponding position.
Mobile System of 30CBM 40CBM Cement Bulk Tanker
At present, the 30CBM 40CBM cement bulk tanker semi trailers of 32 to 40 cubic meters mostly adopt the leaf spring suspension with comparibility fewer leaf springs, such as 3 and 4 leaf spring structures. Larger cubic meter cement bulk tank semi-trailers usually adopt a multi-leaf spring structure such as 10 leaf springs. At the same time, the plates corresponding to the number of sheets have different thicknesses. For example, 4 sheets of steel bullets have thicknesses of 20mm, 22mm, and 24mm. For cement bulk tank semi-trailers with different total weights, different specifications of leaf springs are used.
The axles of the 30CBM 40CBM cement bulk tank semi-trailer are mostly drum axles, which are divided into 10t, 13t, 14t, 15t, 16t, etc. according to the tonnage the trailers are carrying.
The 10 ton axles are under the condition of overload and limited load control in recent years. The lightweight axles have been introduced by Fuhua and other manufacturers, but the brake pads are the same as the 13t axle shaft and have ordinary (180) and widened (220) brake pads.
The tires of the 30CBM 40CBM cement bulk tank semi-trailer are mostly 12R22.5 radial tubeless tires. Meanwhile, a small number of 11.00R20 radial wire tires, 11R22.5 radial tires and 12.00R20 radial wire tires are also being used.
The specifications of the wheels, also known as steel rings, always need to match the tire. 30CBM 40CBM cement bulk tank semi-trailers mostly use 9.0×22.5 wheels. Their thickness of the wheels is divided into 12mm, 14mm, and 16mm. Make sure to always chooose different wheels according to different design gross weight and driving road conditions. In recent years, with the increase of overrun control and load limitation, light-weight 12 mm thick normal wheels or aluminum alloy wheels are mostly used for standard vehicles.
Due to the compact structure design of the 30CBM 40CBM cement bulk tank semi-trailer, the connecting rod of the linkage outrigger interferes with the tank body. Therefore, the landing gear of the cement bulk tank semi-trailer are mostly single-action. It can be divided into 8t, 24t, and 30t tonnage according to the dynamic load that can be tolerated. Among them, the 8t landing gear with aluminum alloy structure is being used most often, which should only unfold and support the the weight when the vehicle is unloaded. The 8t landing gear is as a matter of fact a market product under the policy of oversize and load limit.
