The key parts of a side-rolling Dump trailer are the specifications of the beam, the hydraulic system and the diagonal brace. When purchasing a side-rolling dump trailer, users must pay attention to the beam’s load-bearing capacity. For the hydraulic top, try to choose a famous brand, and pay attention to the manufacturer’s welders and reinforcement for the diagonal brace.
- Specifications of the beam:
Due to the uneven force during rollover, the beam’s load-bearing capacity is required to be high. The importance of the beam to a trailer is self-evident. For a side-rolling dump trailer, the beam is generally larger than the beam of a van with the same load capacity.
First, the beam of the side-rolling trailer has a subframe on a flat road, and the beam is subjected to the same force as an ordinary van, but when rolling over, the beam is unevenly stressed, and the longitudinal beam on one side of the diagonal brace beam is stressed, so the requirements for the beam are higher than those for ordinary vehicles;
Second, the goods pulled by the side-rolling dump trailer are generally heavy goods such as steel, stone, and coal, and the beam’s load-bearing capacity is also required to be high.
- The number of hydraulic jacks depends on the tonnage and the bracket must be firm
Hydraulic jacks are important components for rollover. According to different load tonnage, there are generally several diameters such as 110, 125, 130, 150, etc. Generally, the standard load does not exceed 60 tons. 110 5+1 (5 lifting cylinders, one displacement cylinder) or 130 4+1 is used; heavy loads of 80 tons-120 tons generally use 6+1 or 7+1 150 cylinders. Displacement jacks generally use 160 or 180 cylinders.
The most commonly used brand is Haiwo, with better quality and service, but more expensive. There are also other general brands, including a set of 110 5+1 with a liquid pump power take-off, which costs nearly 10,000 yuan.
The hydraulic jack bracket carries a large part of the weight of the cargo when lifting, and the firmness of the bracket is very important. The shaft at the connection between the hydraulic jack and the sub-frame must be protected, otherwise it is easy to bend.
- Diagonal brace reinforcement is very important and the more fulcrums, the higher the reliability
Diagram brace, when rolling over, most of the weight of the cargo is borne by the diagonal brace, so the firmness of the diagonal brace is very important. Once the diagonal brace has a problem, it is easy to cause a rollover accident, so the reinforcement of the diagonal brace is very important. In the above picture, there are 6 channel steels to reinforce one support point. The number of diagonal braces should be reasonable, of course, the more the better. The more rollover diagonal braces, the smaller the force each fulcrum bears, and the higher the reliability. Generally, there are 5 fulcrums for a 13-meter rollover and 6 for a 15-meter rollover. Pay attention to the rotating bracket on the top of the diagonal brace. When rolling over, the pin must be pulled out. If the design here is unreasonable and it is easy to be unable to be pulled out if it is a little bent, it will affect the unloading.
