Patent attributes
A compact rough terrain crane in which an exhaust emission control device and an elevating step are laid out in a compact manner without impairing excellent small-radius turning performance is provided. The crane includes a lower carrier that has a front axle and a rear axle. The crane includes an exhaust emission control device that has a DOC which is connected to an exhaust pipe extending from a diesel engine and is supplied with exhaust, a DRT disposed downstream of the DOC, and an SCR disposed downstream of the DRT. The crane includes an elevating step. The DOC, the DRT, and the SCR are disposed in parallel on a virtual horizontal plane that is separated from an upper surface of the lower carrier by a predetermined distance. The step is disposed in a gap that is formed between the upper surface of the lower carrier and the exhaust emission control device.
