5 units lowbed semi trailer was installed in the intelligent equipment manufacturing workshop of CIMC, and then will be sent to Tanzania. Over the years, CIMC has sold its products to many countries and regions around the world with its high-quality products and considerate services, and has established a very good reputation in the industry.

CIMC 80 tons step deck trailer for Tanzania

CIMC tri-axle 80 tons lowbed trailer with a low loading height and high payload. It is widely used to carry construction machinery, tracked vehicles, wheel loaders, vessels, boats, combine harvesters, machine parts or prefabricated sections.CIMC production the semi low bed trailer can carry capacity between 40 tons to 100 tons, and we can provide our customers with different tonnage lowbed trailer to meet customer requirements.

Lowbed semi trailer is the economic and flexible solution for numerous different tasks in heavy duty or special transportation. The HG60 high-strength steel semi-trailer we provide is a more durable material than ordinary steel. Its load-carrying capacity is 5 times that of Q345 steel. It not only ensures safety during the transportation of goods, but also avoids unnecessary maintenance to extend the life of the product.

What are the factors affecting the passability of lowbed trailers?

Lowbed semi trailer theory research shows that the passability of a low loader trailer refers to the ability of a step trailer to pass through various road conditions at a sufficiently high average speed under a certain load. 

There are many influencing factors for step trailer passability. From the perspective of giving full play to the power of the lowbed semi trailer, driving speed, car wheels, differentials, driving methods, etc. have an impact on passability; from the perspective of the vehicle technical structure, the minimum ground clearance of the car, Longitudinal passing radius, lateral passing radius, minimum turning diameter, etc., reflect the passing capacity of the vehicle; from the perspective of highway technical indicators, the carrying capacity, slope, bend radius and clearance of the highway limit the passing of the vehicle.

Heavy-duty lowbed semi trailer transportation due to their ultra-long, ultra-wide, and ultra-high characteristics, determine that they are different from ordinary vehicles during transportation, especially in terms of passability, the strength, clearance, and technology of roads, bridges, and tunnels along the way. The conditions have special requirements.

Engineering practice shows that during heavy transportation, air obstacles, road or bridge cargo restrictions, obstructions on roads and facilities above, etc. often impede the passage of transportation. According to the characteristics of heavy transportation work and transportation requirements, it can be summed up. The passability of the vehicle includes the following aspects.

Overall capacity

Due to the ultra-high and ultra-wide width of large objects, the clearance size of roads, bridges, tunnels and buildings on the road must be passed to ensure the safe passage of transportation vehicles.

Road load capacity

The load tonnage of large parts transportation is generally large, and the roads and bridges that need to pass through the ground and have large loads should have a large area with sufficient load capacity. Therefore, the roads and bridges need to be analyzed and checked. If it does not meet the strength requirements, it will inevitably cause the vehicle-cargo system to be unstable and cause a safety accident.

Curve passing ability

Usually highways are designed according to highway technical standards, but because the large-sized transportation vehicles are different from the ordinary design vehicles based on highways in terms of both the shape of the equipment trailer and its turning ability, it is necessary to check the curve data of the highway along the way to Determine whether the vehicle can pass safely.

Horizontal and longitudinal capacity

The cross slope and longitudinal slope of the highway have a great influence on the stress system of transportation lowbed semi trailer and cargoes. From the previous vehicle stability analysis, it can be seen that if the cargo has a certain strapping method, if its maximum lateral and longitudinal tilt angle exceeds the allowable The angle will destroy the stability of the transportation vehicle, which means that the transportation vehicle cannot pass through such a steep road.

Compared with the container flatbed trailer, its center of gravity is lower, and its stability and safety are better. Therefore, it has a stronger ability to transport high cargo and pass overhead obstacles. When loading mechanical equipment on a low loader trailer, we usually load the mechanical equipment from the rear of the semi-trailer, that is, generally use the method of moving the mechanical equipment from the rear wheel frame or removing the wheels, and then fix the mechanical equipment on a lowbed semi-trailer.
