<p>A vehicle suitable for carrying out work at elevated positions, includes a rotary base (1) disposed at a rear portion of a frame (F) of the vehicle, a folding arm assembly (21, 22) mounted on the rotary base for vertical extension thereof, a boom assembly having an axially extendible first jib (21) supporting at its distal end a work platform (3), a front axle (5) disposed at a front portion of the frame (F), and a rear axle (4) disposed at a rear portion of the frame and rearwardly of the rotary base. The rear axle has a pair of wheels (41, 42) projecting laterally of the vehicle on opposite sides thereof by a greater extent than do a pair of wheels (51, 52) on the front axle. The boom assembly also has a second jib (25) disposed in parallel with the first jib and supporting at its distal end a counterweight (251) to balance the weight of the platform (3), the second jib being axially slidably such that the first and second jibs move towards and away from one another by equal extents. The vehicle also includes a discrete load cart (7) connected to the rear end of the frame (F), the cart supporting thereon a box-shaped pallet (73), and a tubular bellows chute (74) expansibly extending between the box-shaped pallet and the platform (3).</p> |
