ABSTRACT:
A vehicle for aerial working includes a vehicle, a rotary base disposed at a rear portion rearwardly of a frame of the vehicle, a folding arm assembly on the rotary base for vertically extending its arm, a boom assembly having an axially extendable first jib supporting at its distal end an aerial platform, a front axle disposed at a front portion of the frame, and a rear axle disposed at the rear portion and rearwardly of the rotary base, the rear axle having a pair of wheels oppositely sidewardly projecting beyond a pair of wheels of the front axle. The boom assembly also has a second jib disposed in parallel with the first jib and supporting at its distal end a counterweight to balance with the weight of the aerial platform, wherein the second jib axially slides to move toward and away from the first jib to an extent same as the latter moves. The vehicle also includes a discrete load cart connected to the rear end of the frame, the cart supporting thereon a box-shaped pallet, and a tubular bellow chute expansibly extending between the box-shaped pallet and the platform.
