2074269 9110590 PCTABS00006 A rigid stabilizer bar (36) is suspended from a quick-release cargo hook attachment point (14) of a helicopter, and a yoke structure (44) is releasably carried by the hook (12) in fixed relation to the bar for suspending a load (32), opposite ends of the yoke having flexible lines (58) connected to spaced apart locations (60) on the load. Opposite ends of the stabilizer bar are connected by bungee cords (40) to landing skid anchors (42) for stabilizing the yoke. The load is oriented by yawing and rolling maneuvers of the helicopter. In an emergency, the yoke, together with the lines and the load, can be jettisoned from the vehicle by releasing the hook. The load can be a dispensing module (70) for directing a fluidic medium such as crushed walnut shells in high-pressure air blast from a nozzle (94) that is located on a boom (96) projecting from the module, onto an elevated workpiece (76) such as an insulator of a transmission line tower (72) for cleaning the insulator. The cleaning module produces a stream (104) of particulate. The helicopter can fly with the module suspended beside the insulator, the nozzle being aimed relative to the workpiece horizontally by yawing the helicopter and vertically by rolling the helicopter. The nozzle is also movable, and the boom can be raised and lowered by remote control for effective access in a variety of workpiece configurations. The module also generates foam for fighting fires.
