Abstract
A discharge arm assembly for a truck or trailer-mounted pumping unit comprises a jumper line which is connected to the outlet of the pumping unit, a base unit which is connected to the outlet of the jumper line, and an articulated arm which is connected to the outlet of the base unit. The base unit includes a base conduit which is rigidly secured to the truck or trailer and a swivel arm which is rotatable about a generally vertical axis. The articulated arm comprises a first generally straight pipe which is connected to the swivel arm by a generally 90° elbow. A brace member comprises a first end which is connected to the swivel arm and a second end which is connected to the first pipe to thereby support the first pipe for movement in a generally horizontal plane.
