摘要
3节式托臂在我公司清障车上已广泛使用，所有的中、重型清障车几乎都使用3节式托臂，它相对于2节式托臂的优点在于：全缩回状态长度相同时，全伸出3节式托臂的长度比2节式托臂长约1／3。
Having discussed and analyzed the flex order of 3-knurl support-arm of YUEHAI wrecker, me author concluded that the cross-shaft of the support-arm is specifically designed to be freely turning around when all support arms are back to the normal position no matter whether it is under condition that one arm is stretching out or three arms simultaneously, which effectively prevent the hauled vehicle from accident when turning on the road.
