Introduction to Knowledge Related to Flatbed Trucks
Flatbed truck Typically equipped with pneumatic solid tires, these flatbed trailers feature a low deck height and high payload capacity. They eliminate the risk of tire damage or blowouts, offering safety, simplicity, and durability. As they are non-powered, they must be towed by tractors or forklifts. A typical train consists of one or more flatbed trailers coupled with a forklift or tractor unit, enabling horizontal cargo transport and the handling of large equipment. These systems are widely used in airports, ports, railway stations, factories, and large warehouses, significantly enhancing the efficiency of cargo transshipment and handling while reducing labor and forklift-related operating costs.
In northern regions, flatbed carts have relatively long handles. When the cart is parked, the front end of the handle rests at an angle on the ground, with both ends lying in the same plane as the two wheels, ensuring stable parking. In some southern areas, by contrast, flatbed carts are lighter and have shorter handles, with the center of gravity positioned opposite to that in the north. At the rear ends of the cart, two sturdy hardwood beams are often reinforced; the length of these beams depends on the height of the person pulling the cart. When parking, one need only slightly raise the arms to keep the cart steady, eliminating the need for the awkward bending motion of first lowering and then pulling, thus conserving energy.
By the 21st century, the KPD(S) series electric flatcar had evolved into a 36V low-voltage track-powered electric flatcar, operating on power supplied via the track’s overhead trolley wire. A ground-mounted step-down transformer control cabinet reduces single-phase (or three-phase) 380V AC to a safe 36V single-phase (or three-phase) voltage, which is then fed to the flatcar through the traveling track—specifically, the conductor rail of the feed line—and subsequently stepped up by an onboard boost transformer back to 380V single-phase (or three-phase) AC to power the flatcar’s single-phase capacitor motor (or YZ three-phase hoisting and metallurgical motor). This equipment is widely used in industries such as metallurgy, coal mining, mechanical and electrical engineering, heavy industry, and shipbuilding.
