    A day in the life of a WABCO scoopmobile Model HPD

    Some random shots of an obscure loader at work....loading, fueling, raising, hauling, moving, and just posing. 50's scoopmobile model HPD with the 3-53 GMC diesel.

    Interesting machine that was probably before its time. If you look at some of the shorter reach material handlers on the market, they look to be from the same gene pool. Long pivot mounted boom, extended reach and dump height and maneuverability with the single rear pivot wheel. Of course the newer machines have pivot/crab/4 wheel steer instead of a single wheel on the rear end but the concept is the same.

    Really like the picture of the machine running down the side of the road with the Jimmy pouring some smoke. Wear your ear plugs.

    That's a really cool rig!

    I imagine its got to have some serious lead in the rear end to keep from tipping over, though.....

    Why the struts beside the front wheel? They don't look like they're attached to the side well enough to provide much strength.

    The struts attached to the front wheels are not structural - rather they're part of the drive train. There are planetary gear sets in the hubs of the axle; the strut is splined onto the inner gear of the planetary in order to lock the gear in place and provide the gear reduction & associated transfer of drive torque to the frame of the machine.

    A side benefit is these struts can be easily removed, which effectively disconnects the entire powertrain (including the differential) from the wheels; this was to allow towing of the machine; there is a towbar that can be attached to the single wheel at the back of the machine. In this configuration the machine could be towed on streets at moderate speeds.

    re: weight in rear

    Yes, the entire back end of the machine is very heavy construction (akin to a forklift) to provide a counter balance to the boom. The boom can lift 8,000-10,000 pounds before it starts feeling light on the back end.

    A drawback of this is the back end sits very heavy on the single rear wheel, which makes it prone to finding the softest earth available. I've learned that on several occasions.

    It has power steering in the rear to make up for the heavy weight back there.

    That is a cool setup for towing
