摘要： The present disclosure provides a backhoe boom lock for engaging a hook member of a boom in a transport position. The boom lock includes a pair of side members disposed parallel to one another along a substantially horizontal axis, each side member having a first end and a second end. A transverse member is coupled between the first end of the pair of side members, the transverse member is configured to engage the hook member in the transport position. The boom lock further includes a pivot point defined near the second end of the pair of side members, the pair of side members being pivotally coupled with respect to the pivot point such that the boom lock pivots about the pivot point. A flange is disposed between the second ends of the pair of side members and is further disposed outwardly from the pivot point at an angle with respect to the horizontal axis. The boom lock also includes a counterweight body integrally coupled to the second ends of the pair of side members.
