摘要
A hydraulic boom assembly comprises a base and a first boom arm extending from the base. A second boom arm is pivotably coupled to the first boom arm. There is a hydraulic system for actuating the first boom arm between an extended position and a retracted position, and for pivoting the second boom arm. A work platform is coupled to the second boom arm. The work platform is provided with a brake mechanism that is independent of the hydraulic system for actuating the first boom arm and pivoting the second boom arm.
