This 1.8m×1.3m electric freight trike with a cargo box specification is an upgraded model designed for heavy-duty and high-frequency transportation. It combines the features of manganese steel plate cargo boxes and large car-type tires, with the following detailed configuration and advantages:
1. Core Hardware Configuration (Targeted Upgrades)
1. Cargo compartment (core advantage)
• Size and Capacity: The rectangular cargo compartment measures 1.8m × 1.3m, with an effective loading area of approximately 2.34 square meters. It is suitable for long items such as pipe materials, sheet metal, and long boxes. The longitudinal length allows for the fitting of long items, while the lateral width can accommodate large or multiple items of cargo. Compared to a standard 1.5m × 1m cargo compartment, this design offers a 30% increase in loading capacity.
• Material characteristics: High manganese steel plates (high manganese steel) have a hardness that is 2-3 times higher than ordinary cold-rolled steel plates, making them more resistant to impact and deformation. Even when frequently loading heavy goods such as stone, metal parts, and building materials, they are less likely to sink or crack. Moreover, they have better corrosion resistance and a longer service life of 1-2 years compared to ordinary steel plates.
• Structural Design: The side panels of the cargo compartment are reinforced with punching patterns (vertical bars visible in the diagram), further strengthening the bearing capacity. The sides and tail can be folded, and the likely hydraulic tailgate function (hydraulic control devices are located next to the cargo compartment) is equipped, which means that when unloading bulk goods such as sand and gravel, agricultural supplies, or waste materials, there is no need for manual handling, significantly improving efficiency.
2. Walking System (Heavy-Duty Adapter)
• Tire configuration: Large car-type tires (judged from appearance as 6.00-13/6.50-16 specifications for heavy-duty tires), with deep tread patterns and thickened side walls. Compared to ordinary tricycle load-bearing tires, it improves traction by 40%, with a single tire bearing capacity of over 800kg. It is suitable for rural dirt roads, construction sites with unpaved surfaces, and is less prone to tire burst or slipping.
• Wheel rim and shock absorber: The combination of thickened steel wheel rims (resistant to deformation), and the rear wheels use a leaf spring plus hydraulic shock absorber combination, which can cushion the bumpy road surface when carrying heavy loads, protecting the frame and cargo, and simultaneously reducing the jolting sensation for the driver.
3. Power and Load Carrying
• Motor/Battery: Adapts to heavy-duty requirements, equipped with a standard 1500W-2200W high-power permanent magnet brushless motor, with a climbing ability of ≥20°. It can easily handle urban and rural inclines; the battery is typically a large-capacity 60V58Ah/72V60Ah lead-acid battery (or optional lithium battery), with a full charge range of 50-70km (under heavy-duty conditions);
• Chassis Structure: The chassis is made of thickened square tubes welded together, and the welded joints with the manganese steel cargo box are reinforced. The overall rated load capacity is over 1500kg, far exceeding that of conventional electric tricycles (500-1000kg).
II. Core Advantages and Adapting Scenarios
1. Core Advantages
• Outstanding load-bearing capacity: The combination of manganese steel plate cargo box + car-type large tires + large-power motor can stabilize the transportation of heavy goods such as building materials (cement, sand and gravel, reinforcing steel bars), agricultural inputs (fertilizer, grain), and industrial raw materials;
• Durability: The high-manganese steel cargo box is robust and the tires are wear-resistant, suitable for daily high-frequency transportation, reducing maintenance and replacement costs;
• High-efficiency loading and unloading: Hydraulic self-unloading + large-size cargo box, whether it is bulk goods or long items/large goods, the loading and unloading efficiency is much higher than that of ordinary tricycles.
2. Compatible Scenarios
• Construction site/Building materials transportation: Hauling sand, cement, bricks, pipe materials, etc.
• Agricultural inputs/agricultural products transportation: Farm haul of fertilizers, grains, and wholesale market haul of fruits and vegetables (larger cargo vans can carry more).
• Industrial/Warehouse Transportation: Moving raw materials and finished products within the factory, and short-distance distribution of large parcels in logistics parks;
• Urban and rural large-volume distribution: bulk freight transportation for express delivery and supermarkets.
3. Usage Notes
1. When overloading, it is recommended to control the vehicle speed (≤25km/h), avoid sudden braking and acceleration, to protect the battery and motor.
2. Although the manganese steel cargo box is durable, it needs to be cleaned in time after long-term contact with corrosive goods (such as fertilizer, acid and alkali liquids) to prevent rusting;
3. Large tires for cars need to be checked regularly for tire pressure to avoid driving with low air pressure that could damage the tire walls.
