摘要：
A boom is mounted by a linkage on the forward member of an articulated vehicle. A link connects the forward member to the boom and in front of this an hydraulic piston and cylinder also connects the forward articulated member to the boom. Rotation of the link will move the boom forwardly or rearwardly while extension and retraction of the piston and cylinder raises and lowers the boom.
