The operation of a dump trailer is very important, especially in terms of safety; we are in the process of operation and we must do a good job in all aspects of safety checks according to norms and standards to ensure that there are no mistakes.
Dump trailer loading safety checklist
Our first step is to do a security check, the following is a checklist that we organize.
- 1. if the ground is level and can support the weight of the dump trailer when lifted.
- 2. check all parts of the dump trailer, especially the hydraulic cylinders.
- 3. check the air pressure of the tires and the suspension of the vehicle.
- 4. check the pipes to make sure that there are no breaks.

The dump semi trailer should use hydraulic cylinder in the lifting process. The power of hydraulic cylinder comes from the tractor.
How to safely operate a dump semi-trailer
Proper loading and unloading of a dump semi-trailer plays an important role in trailer performance, trailer life and, most importantly, trailer safety.
To properly load a trailer, you must consider: total load capacity, load distribution, proper hitch weight and load securement. With these factors in mind, here are 5 helpful tips for loading and unloading a dump semi-trailer:
- 1. Park the tractor and trailer on firm, level ground when loading
- Minimize the center of gravity
- 3. Use stabilizers or flaps when loading equipment from the rear.
- 4. Be aware of your surroundings when downloading
Both loading and unloading must be done on level and firm ground.
Whether loading or unloading, the floor is definitely the place where the most force is applied, so we must find a flat, hard surface to avoid accidents. It is important to realize that accidents often occur when loading and unloading on uneven surfaces.
This may not always seem possible, but it is worth taking the time to do your best. Attempting to load on a loose or uneven surface can cause the trailer to tip over, which is extremely dangerous for you and your trailer. Uneven surfaces also make it difficult to properly distribute the weight of your load. Excessive loads in the front will put pressure on the hydraulic lift and may even overload it. Excessive loads in the rear can cause the trailer to sway at high speeds.
Keep the center of gravity as low as possible.
Load heavy objects on the ground and on the axles. When loading other objects, try to maintain even lateral weight distribution and proper hitch weight. Remember that the trailer axle carries most of the weight of the trailer and its contents, with the remainder of the total weight carried by the trailer hitch.
Do not go too fast during charging.
The goods commonly transported by the dump semi trailer are coal, sand and gravel, etc. Generally, we will use an excavator to load, but during loading, we should load slowly.

Pay attention to the environment when unloading.
When unloading a dump semi-trailer, you must also make sure that the trailer and tractor are located on a firm, level surface for the reasons mentioned above. You should also clear the area around the dump semi-trailer before unloading. When operating the tipper controls, be sure to stand in a safe position away from the tipper body. Before lifting the dump body, check for overhead wires and other obstructions. Also make sure the rear doors are open and secured with door brackets before lifting the bed.
This is just a short list of things to keep in mind when operating a dump semi-trailer. There are many other things you must do to ensure the safety and long-term use of your trailer. Just like any other tool, a dump semi can be extremely beneficial when used correctly and extremely dangerous when used incorrectly.
How to unload a tipper semi-trailer
- In the loading process, avoid disconnection between the dump trailer and the tractor in case the dump trailer overturns.
- The load must be evenly distributed to prevent the dump trailer from tipping over while driving or unloading.
- Park the dump semi-trailer and tractor on level ground before unloading.
- The tractor and dump trailer must be aligned.
- Make sure that the body of the dump trailer does not hit anything when lifting, such as power lines, trees, etc.
- If the dump semi-trailer is equipped with air suspensions, remember to lower the suspension height first.
- Increasing the motor speed during unloading is not necessary, and the process cannot be interrupted.
- Do not pile all the goods on the end of the dump trailer in case of a tip-over during the unloading process. Instead, unload while walking.
- Load accumulation at the end of the dump trailer can lead to lifting failures.
- The cylinder is not used for stabilization, but only for lifting and lowering. Therefore, it cannot receive lateral traction during the working process.
- The cylinder should not continue to run for more than 30 minutes.
- For safety, stay as far away from the dump trailer as possible during operation to prevent accidents.
- The cylinder must be fully retracted after unloading.
- Remember to move the tipping lever to the neutral position, ending the discharge one minute later.
- Make sure that the working pressure of the cylinder does not exceed the specified value.
- The engine oil should be changed every 6-9 months. The time interval should be shortened if it is used more frequently.
- Include these inspections in a daily routine: the condition of the hydraulic hoses, the connecting hose between the cylinder and the hydraulic system, the quick connector and the cylinder support. Also, lubricate the fulcrum and tighten the support bolts regularly.
- Following the above operating rules can effectively prevent the hazard, as well as prolong the service life of the dump semi-trailer.
