Specific design of semi-trailer for livestock and poultry transportation

1、 Hierarchical Structure: Balancing Space Utilization and Animal Welfare
Double/triple layer layout
Large livestock transportation: such as the 13 meter double decker high rail livestock transportation semi-trailer, which adopts a beam through frame structure to ensure strength and lightweight. Guardrails should be installed between the upper and lower levels to prevent animals from falling. For example, a certain double-layer cattle and sheep transport vehicle is driven by an electric motor to achieve lifting and unloading, which is convenient for loading and unloading.
Transportation of small and medium-sized livestock: For example, the 2-story 13 meter pig transport truck designed by Huayun United has 3 layers of compartments, each with a height of 831mm and a total of 19 compartments. It can transport 200 fattening pigs at a time. Set up partitions on each floor to reduce the risk of conflicts.
Column division
Density control: Adjust the column area based on animal species and body size. For example, each fattening pig needs to occupy an area of ≥ 0.43 square meters to avoid overcrowding and stress.
Mobile floor design: Some car models use foldable or movable floors, such as a movable floor between the first and second floors of a pig transport vehicle, allowing operators to flexibly adjust the space to accommodate animals of different sizes.
2、 Ventilation and Environmental Control System: Ensuring Air Quality and Comfortable Temperature
ventilation system
Airflow organization: Using inlet ducts, guide ducts, and swinging components, the airflow flows from the middle to both sides, ensuring comprehensive gas exchange inside the carriage. For example, a patented ventilation system uses air volume and air pressure adjustment components to stabilize the airflow velocity entering the cabin.
Exhaust design: Install exhaust fans on the top or side walls of the carriage, and use louvers to achieve air circulation. As for the passenger type livestock and poultry transport vehicle, 6 controllable exhaust fans are installed on the top of the vehicle, and 6 air intake louvers are arranged on the side panels.
Temperature Control System
Refrigeration and Heating: Equipped with a car mounted refrigeration unit, warm air unit, and gas mixing and conveying compartment to achieve precise temperature control. For example, a pig transport truck monitors the temperature in each area through a temperature control probe and automatically adjusts the air conditioning according to the set value.
Floor heating: The interior floor of the cabin is equipped with a heating system, such as heat dissipation pipes embedded in the floor, which does not occupy space and automatically starts and stops through temperature control induction.
Spray and cleaning system
Spray cooling: composed of an air pressure water tank, pipes, and nozzles, it sprays and cools animals while cleaning the interior of the cabin. For example, pig transport vehicles are equipped with sprinkler systems, and sewage is discharged through collection tanks, which meets environmental protection requirements.
Automatic fecal cleaning: Some car models use sloping flooring or automatic fecal cleaning devices to reduce fecal residue and lower the risk of disease transmission.
3、 Materials and Structure: The Combination of Lightweight and Durable
Frame material
Application of high-strength steel: High strength steel with a yield strength of ≥ 700MPa, such as T700 steel, is used to reduce self weight while ensuring bearing capacity. For example, a 13 meter two-story livestock and poultry transport semi-trailer adopts a through beam structure, with longitudinal and transverse beams welded together to form a spatial framework, ensuring strength and rigidity.
Aluminum alloy components: Some car models use aluminum alloy materials instead of steel, such as legs, rear panels, etc., to further reduce weight. For example, the main body structure of a pig transport truck is made of aluminum alloy material, which is corrosion-resistant and lightweight.
Carriage design
Fence structure: The carriage is designed with a fence around it to ensure good ventilation. For example, the frame of a warehouse style semi-trailer is a through beam structure, with straight or goose neck longitudinal beams and a web height of 400-500mm, balancing strength and lightweight.
Anti slip flooring: The flooring is treated with anti slip carving to reduce the risk of animal slipping. For example, the floor of a pig transport truck is made of 2.5mm chemical resistant patterned boards to increase friction.
4、 Humanized operation and safety design
Loading and unloading system
Hydraulic lifting tailboard: The rear of the carriage is equipped with a hydraulic lifting tailboard, which is level with the farm unloading platform, making it convenient for animals to get up and down. For example, the hydraulic tailboard of a pig transport truck can automatically unfold to form an access channel, with guardrails to ensure safety.
Slant ladder design: Some car models use foldable inclined ladders, such as the stairs of the Huayun Union Pig Transport Vehicle, which are foldable inclined ladders for easy loading and unloading of fattening pigs.
Monitoring and alarm system
Real time video monitoring: Install cameras in the carriage to monitor the status of animals in real time. For example, pig transport vehicles are equipped with video surveillance and temperature alarm devices. If the temperature inside the carriage exceeds the safe value, the cab will automatically sound an alarm.
Lighting system: LED lighting fixtures are installed inside the cabin for easy nighttime operation. For example, LED lighting is installed inside the compartment of a pig transport truck to ensure clear visibility for the operator.
safety protection
No sharp edges: There are no dead corners or sharp edges in the carriage, reducing the risk of animal injury. For example, the overall design of the pig transport vehicle avoids sharp edges and corners, and the ground is treated with anti-skid measures.
Emergency braking: equipped with ABS anti lock braking system to ensure driving safety. For example, the suspension system of a warehouse style semi-trailer adopts a new design, with balanced axle loads and reduced tire wear.
