The LUYI three-axle 30-cubic rear-reversing semi-trailer is equipped with an airbag lifting structure for the first axle. When empty, it lifts the first axle to reduce rolling resistance and decrease tire wear. In a year, this can save a considerable amount of fuel costs for transporting sand, gravel and earth in mining areas. This three-axle 30-cubic rear-reversing model is designed in accordance with the external dimensions limit of GB1589 and the safety technical conditions of JT/T 1178.2. The compartment volume is 30 cubic meters. It is equipped with three 13-ton axles and a WABCO relay valve along with 4S/2M ABS. Under heavy load, the braking is responsive. This model has been widely used in African and Central Asian earthwork projects.

Core Strengths
The first shaft lift is extremely fuel-efficient. After lifting the shaft while empty, the turning radius is reduced by approximately 1.2 meters. The actual fuel consumption per 100 kilometers has decreased by about 6%, the tire wear has been reduced by approximately 25%, and a vehicle can save a considerable amount of operating costs per year.
Discharge cycle is fast. The double-acting lifting cylinder is equipped with a large-flow gear pump, and it takes less than 35 seconds to complete the full-load lifting when fully loaded. With a single shift, it can make two more trips, and the efficiency of short hauls in the mining area has increased by approximately 20%.
The enclosure is corrosion-resistant and does not rot. After the entire vehicle is shot blasting for rust removal, powder coating and baking are carried out, with a film thickness of no less than 90 microns. The salt spray test shows no blistering after 500 hours, and it does not stick to the enclosure even when wet sand and slag are applied, remaining rust-free.
There is sufficient redundancy for braking. The disc brakes are equipped with dual-chamber air chambers and WABCO relay valves, and the ABS is arranged according to 4S/2M. Under a full-load of 60 tons, the braking distance can be controlled, and it is not prone to skidding on slippery roads.
Lightweight without reducing strength. The aluminum alloy wheel rims reduce the unsprung mass, and the vehicle is approximately 120 kilograms lighter than the steel rim model of the same specification. It can carry more cargo without exceeding the axle load.
Maintenance requires fewer personnel. The hydraulic oil tank and ladder are integrated on the front side of the enclosure. A single person can complete the daily inspections of oil level, pipelines, and rubber strips within 10 minutes.

Qualification Certification
The company holds the special vehicle production approval certificate issued by the Ministry of Industry and Information Technology, has passed the ISO9001 quality management system certification, and its products have obtained CCC compulsory certification. For the export side, it can issue CE certification, Kenyan PVOC, Nigerian SONCAP, origin certificate, and third-party inspection reports. Core components use first-line brands such as WABCO brake valves, 12R22.5 all-steel tires, and 3M reflective signs, and the batches can be traced. The factory inspection is entrusted to CCIC and TÜV Rheinland for execution, and load-bearing, braking, and lifting performance reports are issued. The documents can be directly used for customs clearance at the destination port.

Customer feedback
Kenyan quarry customers use this three-axis 30-cubic rear dump crusher for crushing stones. The enclosure has remained undamaged for 11 consecutive months. The first-axis lifting is significantly fuel-efficient when the vehicle is returning empty. Zambian copper mine customers use it for short dumping of mine waste. When fully loaded, it can climb slopes without losing speed. Customers from Uganda and Vietnam have reported that the entire vehicle can be cleared through customs smoothly and can be put into operation without the need for additional rectification. The chat records, pickup photos, and on-site unloading videos of overseas customers can all be provided for verification.

Packaging Logistics
The rear-dumping semi-trailer for sea transportation has three methods: single-load shipping on bulk cargo ships, with wooden planks placed under the frame and four-point steel wire ropes for binding, and spraying marine rust prevention wax; 40-foot high containers use loose packing, removing the tires, legs, and enclosure accessories, and each container can hold one complete machine or two loose parts, resulting in lower freight costs; the entire vehicle is driven into the ship's hold and can be picked up upon arrival at the port.
