Flatbed truck

A flatbed truck is a large vehicle with a flat body and has no sides or roof around the bed. Its shape makes loading and unloading in a way I could do it with my eyes shut. In North America, the length is commonly 48 or 53 feet (14.63 or 16.15 m), and the width is either 96 or 192 inches (2.44 or 4.88 m) (including rub rails and stake pockets on the sides, which are generally placed every 2 feet or 61 cm).Various lengths and combination setups can only be legally driven on turnpike/toll roads which are far too long for most roadways. The maximum weight capacity for a flatbed truck varies widely, depending on a variety of factors. In general, though, you can expect the bridge weight capacity to be in the neighborhood of:

• 24-Foot, Three-Axle Truck: 54,000 Pounds Maximum Load
• 36-Foot, Four-Axle Truck: 66,000 Pounds Maximum Load
• 51-Foot, Five-Axle Truck: 80,000 Pounds Maximum Load
• 43-Foot, Six-Axle Truck: 80,000 Pounds Maximum Load

Body and frame can be one of 3 general designs: 

-the heaviest and sturdiest all steel (usually with wood planks),

-ever-popular combo with steel frame and aluminum bed, these type often have wood portions for nailing down dunnage boards),

-aluminum (which is the lightest allowing for more cargo to be legally carried without overweight permits). Incredibly light and very expensive to purchase, all aluminum trailers are very slippery when wet, flex more and are easily damaged.
