An attachment carriage for a hydraulic boom assembly comprises a work platform. The work platform may be a personnel basket or a fork assembly. A first actuator provides arcuate movement to the work platform about a horizontal axis. A second actuator provides rotary movement to the work platform about a vertical axis. The first actuator and the second actuator are hydraulically independent of a hydraulic system of the hydraulic boom assembly. The first actuator may be in hydraulic communication with a levelling valve. There may be means to reciprocate the work platform along the vertical axis. The first actuator and the second actuator may be integral.
