The 41.440 chassis designation describes a 41 ton GVW with a 440 DIN BHP engine. The payload capacity for the container and its contents would most likely be approximately 20 to 22 tons. This 8X8 chassis cab is pretty heavy by itself with its four drive axles, and it has the hydraulic lifting gear and rail system for the swap bodies too.
This type of chassis is most commonly used in oilfield applications, to carry heavy equipment across unmade roads, and is also used as a military transport.
