8-Axle Hydraulic Heavy-Haul Semi-Trailer

JinFeng China 8-Axle Hydraulic Heavy-Haul Semi-Trailer is a flagship heavy cargo transport vehicle developed by Shijiazhuang Jinfeng Special Vehicle Co., Ltd. for overweight and oversized cargo transportation. Adopting the 8-axle load bearing structure, its main beam is made of high-strength alloy steel with box section. Combined with multi-axle uniform load technology, the vehicle has greatly improved load limit and torsion resistance, capable of transporting hundred-ton-level heavy equipment.

Equipped with mature hydraulic modular axle system, it supports independent full-wheel hydraulic steering and axle height adjustment, enabling flexible passage through narrow roads and complex road conditions. The built-in hydraulic ramp with spring buffer structure makes loading and unloading engineering machinery safer and more labor-saving. Optional accessories including hydraulic gooseneck, extended and widened platform modules can meet diverse transportation demands for wind turbine towers, tunnel boring machines, large transformers, bridge components and other large goods.

Manufactured in strict accordance with national standards, key hydraulic and brake parts adopt renowned brand components. Every unit has passed multiple heavy-load and reliability tests to ensure stable performance and long service life. This trailer is widely applied in power infrastructure, mining engineering, chemical equipment and other sectors.

Pre-loading Inspection

Before use, fully inspect the hydraulic system, brake system, tire pressure and fasteners to ensure no leakage or looseness. Check the weight and placement of goods strictly. Never exceed the rated load capacity of the vehicle. Secure oversized goods with anti-slip measures to prevent displacement during transit.

Driving Safety Regulations

Apply for over-limit transportation permits in advance and work out proper routes to avoid height-limited, width-limited and rough road sections. Drive at a steady low speed and refrain from sudden braking or sharp turning. Operate the hydraulic modular axle steering only at low speed to avoid overload of the hydraulic system. Arrange professional staff to follow and supervise the vehicle on complicated roads.

Loading and Unloading Requirements

Park the trailer on flat and solid ground when loading and unloading heavy equipment. Engage the parking brake and chock the wheels. Confirm the hydraulic ramp is fully locked after unfolding. Keep a constant low speed when equipment moves on and off the ramp. Avoid rushing or sudden stops to prevent rollover and cargo falling.

Daily Maintenance

Regularly check the level and quality of hydraulic oil, and replace hydraulic oil and filters periodically to prevent pipeline blockage caused by impurities. Examine axle bearings and tires frequently, and replace worn parts timely. For long-term parking, support the vehicle steadily, release the pressure of hydraulic system, and take anti-rust and moisture-proof measures to extend the service life.

Application Scenarios

JinFeng China 8-Axle Hydraulic Heavy-Haul Semi-Trailer serves a full range of heavy equipment transportation scenarios. It is widely used to haul wind turbine towers, engine rooms, large transformers, bridge components, tunnel boring machines, loaders, excavators, heavy industrial castings, boilers, chemical towers and other oversized goods.

With superior 8-axle load bearing and hydraulic modular axle performance, it copes well with long-distance highway transportation as well as transfers on rugged roads at construction sites and mining areas. It has become essential transport equipment for power, infrastructure, mining and chemical industries, providing safe and efficient solutions for all kinds of overweight and oversized cargo delivery.
