With the development of modern hydraulic technology, large-scale transport vehicles begin to use hydraulic flatbed trailers, or add some components based on hydraulic flatbed trailers to form other forms of vehicle groups.
Usually, the vehicles for highway transportation of large items are always car trains composed of tractors and trailers. Obviously, the tractors, trailers and their coordination conditions constitute the main factor affecting the reliability of transportation vehicles.
In the field of large-scale transportation, we often see the words SPMT axis car, Nicholas axis car and brand names such as Scheuerle, Goldhofer, Cometto. Today, we will talk to you about the structure and composition of these cars and their magic.
A semi-trailer is a trailer whose axles are placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and are equipped with hitches that transmit horizontal and vertical forces to the tractor.
SPMT modular trucks are mainly used in the transportation of heavy and super-large structures.
The SPMT module flatbed truck smoothly translates the old building into place, which reduces the translation time, improves the work efficiency and reduces the construction cost.
The concentrated load of the house is distributed to the trailers on both sides by the lifting beam, so the design of the pallet is particularly important.
SPMT used to relocate house With the development of society, the state pays more and more attention to the protection of ancient buildings and modern buildings.
Under the condition that both the cargo weight g and the action position l satisfy the inequality, the stability requirements for 6-axis carriage plate transportation are met. The figure shows the relationship between the two variables g and l of axis 6 carriage plate under the two marshalling modes of n=3 and n=4, in which the shaded area is the allowable cargo load size and action range.
Since the goods have been firmly tied up with the vehicle body during operation, when the SPMT vehicle cargo system is subject to lateral instability due to external factors, the vehicle cargo system takes the longitudinal axis of the trailer suspension swing arm as the rollover fulcrum. Therefore, the center of gravity in stability analysis should be the combined center of gravity of vehicle and cargo.
