A peening device for treating a component includes a shot media propulsion source configured to propel a quantity of shot media. The device also includes a plurality of treatment enclosures each selectively coupleable to the shot media propulsion source. Each of the treatment enclosures has a shape complementary to a corresponding one of a plurality of portions of the component, such that each treatment enclosure and the corresponding portion cooperate to enclose the shot media.

An independent safety warning and notification system for sandblasting operations that require an operator of a blasting hose to be remotely positioned to the blasting pot operator. A dedicated activation switch assembly is secured to an existing sandblast hose with a separate dead man switch or alternately with an integrated dead man switch allowing the blast nozzle operator to communicate critical information to the pot operator. A warning notification light display and audible alarm assembly with a remotely positional warning light alarm is selectively secured near the pot operator for notification that a prescribed predetermined action has been requested by the blast nozzle operator or an emergency situation by activation of the switch assembly.

A shot processing apparatus including: a cabinet with a processing chamber formed therein, the processing chamber allowing a workpiece to be conveyed thereinto; a ejecting mechanism ejecting a shot media to a hole of the workpiece; and a conveyance device conveying the workpiece between a preparation position for the workpiece and the cabinet, wherein the conveyance device includes a plate-like rotary table provided to be rotatable about a rotation axis, being provided with a conveyor for moving the workpiece on an upper surface of the rotary table, and allowing the plurality of workpieces to be arranged thereon, the rotary table connects the conveyor to the preparation position and the cabinet at a predetermined rotational position, and the shot processing apparatus has an inspection area for inspecting a state of the hole of the workpiece, between the preparation position and the rotation axis of the rotary table.

Reduced noise abrasive blasting assemblies and systems are described. The new assemblies and systems are comprised of standard blast hose, accelerator hose, couplings and nozzle. The improved abrasive blasting system maintains abrasive particle velocity while decreasing the exit gas velocity and consequently decreasing sound production. This is accomplished through an acceleration section with reduced inner diameter and sufficient length to provide the necessary abrasive particle velocity. The new system maintains the productivity and efficiency of conventional abrasive blasting systems but with greatly reduced acoustic noise production and reduces operator fatigue due to the lower weight of the carried portion of the system.

An omnidirectional blast media dispensing apparatus mounted to an excavator and designed to dispense abrasive media from a blast pot is provided. The apparatus adjusts directional flow of the abrasive media exiting the apparatus to contact a desired target. The apparatus includes a housing coupled to the boom of the excavator, a hydraulic motor assembly coupled to the housing and operably connected to hydraulic lines of the excavator, and a main tubular member rotatably mounted to the housing and operably connected to the hydraulic motor assembly. The first end of the main tubular member is coupled to the blast pot and a nozzle is coupled to the second end of the main tubular member. Fluid flows from the hydraulic lines of the excavator to the hydraulic motor assembly to enable the hydraulic motor assembly to rotatably adjust the main tubular member to direct the nozzle toward the target.
