Notes for Attention：
1. Refer to the manufacturer’s attached information of diesel engine and air compressor.
2. Before opening the manhole cover, you must first open the release valve, so that the pressure in the tank and outside of the tank is the same.
3. Do not switch on or off the air compressor when the pressure in the tank is high, and switch on the exhaust valve to release all the air in the tank before switch on or off the air compressor.
4. After loading, you must clean up the material cover seal ring, material cover and its motion mechanism, dust on the operating platform, then close the material cover and discharge valve, and switch on the exhaust valve.
5. Usually, the exhaust valve should be always kept open, avoid vacuum endangering till the reloading. The exhaust valve must be switched on especially after the temperature changes and the tank inside is cleaned.
6. The tank is strictly prohibited to let in water and other liquids. Otherwise, the tank inside must be dried.
7. Discharge on level ground as much as possible.
8. In loading operation, you must confirm that the exhaust valve must be in the "on" position; other valves are in the "off" position. A tank pressure ban on tank set in the operations。
9. Before the unloading operation, you must confirm the receiving storage cabin is of enough capacity, and pay attention to the position alarming in the discharge process. If the cabin is full and alarms, you should first switch off the discharge valve, and continue to blow and clean the pipe for about 1 minute using the propelling device.
10. During the loading and unloading operations, the vehicle must be braked reliably.
11. It is prohibited to release the air in the tank using the discharge pipe.
12. It is prohibited to drive the vehicle when the tank is under pressure.
13. The starting pressure of the safety valve is 0.2Mpa; this value shall not be increased.
14. The check valve must be inspected once a year; the valve core must be replaced or repaired every two to three years.
15. It is forbidden to overload, the materials can be loaded and transported by each tank vehicle relating to the configurations. Tank vehicle exclusively designed for cement, fly ash materials cannot be loaded with other materials. Please contact the manufacturer if the tank vehicle is required to be loaded with other materials. .
16. The manhole cover must be kept completely shut off, so as to prevent the tank damp.
17. It is prohibited to start the air compressor when the intake valve is switched off.
18. It is forbidden to stop freely during the discharge process; otherwise, it could easily lead to pipeline blockage.
19. Before loading, you should confirm that there is no wire, stones and other debris in the tank, and confirm that here is no agglomeration in the loaded materials; the materials can be filtered with mesh if there is agglomeration.

Repairs and maintenance：
1. The sealing of the gas circuit should be in good performance. You should often check whether the pipes and joints crack or are damaged, whether it leaks, whether the switch is leaking, and the leaks must be promptly eliminated if found. Check whether the release valve is blocked; clean the deposits on the valves to ensure operation.
2. You should often check whether installing bolts of all parts loosen. When necessary, tighten the installing bolts.
3. If the tanker is idle for a period of time. Before using, it should be ventilated and dehumidificated, otherwise, the performance may significantly degrade.
4. It shall not be stored for a long time under pressure, so as to avoid the early seal failure and accidents.

We’re thrilled to share some exciting news from our team: a brand-new 4-Axle Side-Tipping Dump Semi-Trailer, specifically built for Guinean bauxite transport, is all set to be shipped to our valued customer in Kenya. This order isn’t just a testament to our expertise in manufacturing heavy-duty semi-trailers—it also highlights how our custom-built side-tipping semi-trailers can meet the unique needs of bauxite transport across Africa, even in the most demanding conditions.

Our Kenyan customer, who specializes in mineral transport and has long been looking for a reliable side-tipping semi-trailer that can handle the rigors of bauxite hauling, chose our 4-Axle Side-Tipping Dump Semi-Trailer after careful comparison. What stood out for them most? The trailer’s robust design, tailored specifically for the challenges of bauxite transport in Guinea and neighboring regions, which aligns perfectly with their operations in Kenya’s mining and logistics sector.

Let’s dive into what makes this 4-Axle Side-Tipping Dump Semi-Trailer so ideal for bauxite transport. First off, its dimensions—13.2m (L) * 2.55m (W) * 3.8m (H), with a cargo box height of 2m—provide ample space for large loads of bauxite, which is crucial for maximizing efficiency in mineral transport. Unlike generic semi-trailers, this side-tipping semi-trailer is equipped with a specially reinforced 4-axle heavy-duty mechanical suspension, ensuring it can handle the heavy weight of bauxite without compromising stability, even on rough African roads.

Durability is key when it comes to bauxite transport, and this 4-Axle Side-Tipping Dump Semi-Trailer doesn’t disappoint. The carriage box is made with a 6mm thick floor and 4mm thick side walls, tough enough to resist the abrasion and impact of bauxite, which can wear down ordinary trailers quickly. We also fitted it with 20-ton 4-axle Fuwa axles—known for their strength and reliability—and 1200R20 mining block-pattern tires, which offer excellent traction and resistance to punctures, perfect for the uneven terrain often encountered in mining areas.

Another standout feature of this custom side-tipping semi-trailer is its lifting system: 7 units of 150-type lifting cylinders paired with 1 safety cylinder. This setup ensures smooth, efficient tipping even with full loads of bauxite, while the safety cylinder adds an extra layer of protection, reducing the risk of accidents during operation. It’s these thoughtful details that make our 4-Axle Side-Tipping Dump Semi-Trailer a top choice for bauxite transport in Africa.

As global demand for bauxite continues to grow, and Guinea remains a key player in the global bauxite market with its rising exports, having a reliable side-tipping semi-trailer is more important than ever. Our Kenyan customer recognized this, and we’re proud to provide them with a custom solution that’s built to last, boost productivity, and handle the unique challenges of bauxite transport.

This 4-Axle Side-Tipping Dump Semi-Trailer isn’t just a product—it’s a partnership. We worked closely with our Kenyan customer to understand their specific needs, from load capacity to durability requirements, and tailored every aspect of the side-tipping semi-trailer to ensure it exceeds their expectations. Whether it’s for Guinean bauxite transport or other heavy-duty mineral hauling, our custom side-tipping semi-trailers are designed to deliver performance, reliability, and value.

We can’t wait to see this 4-Axle Side-Tipping Dump Semi-Trailer in action in Kenya, helping our customer streamline their bauxite transport operations and achieve greater efficiency. If you’re in the market for a high-quality side-tipping semi-trailer—whether for bauxite transport, mining, or other heavy-duty applications—our team is here to create a custom solution that fits your needs. Stay tuned for more updates as we ship this impressive 4-Axle Side-Tipping Dump Semi-Trailer to Kenya!
