Core Selling Points

This model is developed to target and solve core pain points in bulk transportation, with outstanding core advantages: First, the exclusive one-piece U-shaped carriage structure, stamped and formed from 700L high-strength weather-resistant steel, with smooth arc seamless inner wall and no dead corners, achieving completely clean unloading with extremely low residue rate, saving manual cleaning cost and labor, greatly shortening unloading cycle and improving overall transport efficiency. Second, the stable and heavy-duty rear tipping hydraulic system, matched with high-standard hydraulic cylinders, gear pumps and high-pressure oil pipes, with adjustable and controllable lifting speed, maximum lifting angle up to 50-60 degrees, strong lifting power, simple and flexible operation, fully adapting to heavy-load unloading in harsh working conditions. Third, reliable overall quality and long service life, all body welds pass full non-destructive testing, the whole carriage is treated with double-layer anti-corrosion coating, with strong resistance to corrosion, impact and bump; the main frame adopts reinforced thickened design with 16-20mm high-strength steel, excellent bearing capacity and stable structural performance. Fourth, fully compliant and environmental-friendly design, the closed U-shaped structure effectively prevents material scattering and dust emission during transportation, fully meets road administration and environmental protection regulations, avoiding illegal fines and related losses. Fifth, optimized lightweight design, reasonable structural layout reduces dead weight without weakening load capacity, allowing more cargo loading under the same gross vehicle weight, directly improving customers' transport revenue and economic benefits.

Operation and Maintenance

The semi-trailer is user-friendly and easy to operate, equipped with standardized professional control system, enabling drivers to easily control driving and unloading status. It supports customized lifting angle adjustment, can be matched with single-axle or multi-axle chassis, realizing multi-scenario universal use to adapt to different transport and working conditions. Before operation, please check the hydraulic oil level, tire pressure and braking system to ensure no oil leakage and abnormal faults; load materials evenly to avoid center of gravity offset, ensuring driving stability and safety; when unloading, please park the vehicle on a flat and solid site, keep the ground slope within 3° and lateral inclination within 1.5°, confirm that the mechanical locking pin is fully locked before lifting operation to prevent accidental sliding; avoid sudden braking during driving, slow down when turning, and always pay attention to the operating status of each component.

The daily maintenance of the trailer is simple and low-cost, with full after-sales support provided by Jinfeng China to help customers reduce maintenance expenses and downtime. For daily maintenance, please regularly inspect the hydraulic system for pipe damage and oil leakage, replace high-pressure oil pipes every two years, replace hydraulic oil and filter elements on schedule, and strictly prohibit mixing different grades of hydraulic oil; check the welds of the carriage and sub-frame regularly, and repair any cracks or damage immediately; check tire wear regularly, adjust standard tire pressure and clean up foreign matters on the tread; conduct regular maintenance for gear pumps, power take-offs and other moving parts, and replace vulnerable parts in advance; grease the hinge points of the locking mechanism every 500 working hours, clean up dust and debris to prevent jamming. Regular standardized maintenance can effectively extend the service life of the trailer and ensure long-term stable and efficient operation. Jinfeng China provides full-process after-sales guidance, maintenance support and technical services, so that customers can use the vehicle with full confidence.
