Profile: Allentown Shotcrete Technology, Inc. specializes in dry and wet-process shotcrete equipment for the refractory, underground, mortar and civil industries. We offer a wide range of gunning machines, pre-dampeners, pumps, combination mixer pumps, mixers, nozzle carriers, mortar machines and concreting machines. AG-15 Automatic gun is completely automatic and ideal for dry-process shotcrete in civil applications. Material is loaded into the hopper, where a rotary stirring spider loosens it and pushes it down into the U-shaped material pockets of the rotating feed bowl. Compressed air pushes the material out of the feed bowl and into the delivery hose, providing a steady flow of material to the nozzle for even hydration. Our pre-dampeners are designed to be used with packaged, pre-blended materials for dry-process shotcrete applications. Robotic nozzle manipulator is a track-mounted mobile spraying unit designed for automating the application of shotcrete in the underground industry. The machine is ideal for slope protection or for tunneling where a smaller manipulator is necessary.
