Article presents three case studies to illustrate how conveyors--used alone or in combination with other placement methods--can be profitable because they place concrete continuously and are able to transport materials other than concrete. The projects involved:

  • The use of a self-propelled portable belt conveyor to place 200 cubic yards of concrete for a base slab in only four hours
  • The placement of 80,000 cubic yards of concrete for a riverbed at rates exceeding 3.3 cubic yards per minute using a 114-foot-long side discharge conveyor with a 24-inch-wide belt
  • The use of a pair of self-propelled concrete conveyors, a 105-foot boom pump, and a crane and bucket to place 100,000 cubic yards of structural concrete for a dam's piers, spillway slabs and tall reinforced-concrete walls
