Is the safety factor of light semi-trailer guaranteed?

Under the constraints of the 921 New Deal, light semi-trailers have become the mainstream of market demand. In this way, trailer manufacturers are encouraged to rack their brains to reduce their own weight. As far as ordinary semi-trailers are concerned, manufacturers have re-optimized their designs in terms of materials, processes and structures in order to pursue a reasonable and lightweight design. So, is the safety factor of light semi-trailers guaranteed? Let's take a closer look.

 1. Replace the traditional heavy manganese plate with new high-strength steel. On the premise of ensuring the same bearing capacity, high-strength steel has the inherent advantage of being lighter than manganese plate.

 2. Lightweight beams. Through the analysis of finite element material mechanics, it is concluded that the special-shaped punching hardly affects the compressive strength of the girder vertical plate. In addition, the height of the vertical plate can also be reduced from the previous 500mm to 450mm, and the width of the upper and lower wings can be reduced from 140mm to 120mm.

 3. The side beams are replaced by bending parts instead of square tubes. On the premise of not affecting the strength, the weight of the bending part can be reduced by nearly 1/4 compared with the square tube. The general name of the bottom of the shop can also be used to replace the broken channel steel with W-shaped bending parts.

 4. Adopt high-quality lightweight axles. From the previous 16T axle, replaced by the current 13T or 12T.

 5. Use aluminum alloy wheels. Using a single aluminum rim with a weight of about 25KG to replace the 45KG steel rim, the 12 rims of the whole vehicle can reduce the weight by about 240KG.

 6. Replace steel accessories with aluminum alloy accessories. Using aluminum alloy legs, aluminum alloy tool box, and aluminum alloy air chamber, the weight can be reduced a lot after the whole set is replaced.

 7. Reduce unnecessary accessories, such as not using water tanks if road conditions permit, reducing the number of toolboxes or switching to net-type toolboxes.

 8, twins for single tires. Now some manufacturers have applied for the announcement of large single tires of 425/65R22.5 and other models. The single tire is equipped with aluminum alloy wheels, and the weight reduction is also considerable.
