Counter Weight Bottom Loader (CW-30)

Counterweight Loading Arms

CW-30 counterweight bottom loading arms store primary in horizontal position to either side of the riser pipe depending on the piping layout and pre-existing obstructions. These arms rotate above and below horizontal to reach the connection point on the truck. Arms are balanced with counterweights instead of springs. They use the slide scale balance method. They require less overhead space than the AF-54 but require more space adjacent to the arms for storage; either hose or pipe can be used in the drop section to reach the connection point.

Available in Up Feed or Down Feed Loading configurations.
