Abstract
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.

A hydraulic boom assembly comprising:
- a base;
- a first boom arm extending from the base;
- a second boom arm pivotably coupled to the first boom arm;
- a hydraulic system for actuating the first boom arm between an extended position and a retracted position, and for pivoting the second boom arm;
- and
- a work platform coupled to the second boom arm, wherein 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.
A vehicle provided with a hydraulic boom assembly, the hydraulic boom assembly comprising:
- a base;
- a first boom arm extending from the base;
- a second boom arm pivotably coupled to the first boom arm;
- a hydraulic system for actuating the first boom arm between an extended position and a retracted position, and for pivoting the second boom arm;
- and
- a work platform coupled to the second boom arm, wherein 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.
An attachment for a boom assembly comprising a first boom arm and a hydraulic system for actuating the first boom arm, the attachment comprising:
- a dielectric boom arm pivotably couplable to the first boom arm;
- a hydraulic actuator near a proximal end of the dielectric boom arm for pivoting the dielectric boom arm relative to the first boom arm, the hydraulic actuator being connectable to the hydraulic system for actuating the first boom arm;
- and
- a work platform coupled to the dielectric boom arm, wherein the work platform is provided with a brake mechanism that is independent of the hydraulic actuator.
