Now, Normet has expanded this capacity, developing The S20’s usage benefits from its convenient ability to new environments where underground spraying can be prac- perform as a line pump with a standard back-end 180-degree ticed, including mines, tunnels, and even an operator’s own rotating outlet. The unit also features excellent storage for scanned environment. There is also a wide range of Normet clamps, and an additional system with fold-down sideboard tunneling and mining sprayers to choose from, including the access on the driver’s side to a 13 ft (4 m) loading deck.

In the pretraining scenario, the trainee learns how to (229 mm) diameter pumping cylinders. The twin-cylinder manipulate the spraying boom with the machine’s original all-hydraulic unit sequences the pumping cylinders through radio control. Once fluent with manipulation of the spraying the proven M Rock Valve, providing maximum sealing boom, a basic spraying technique exercise can be started. This efficiency in a totally rebuildable valve with a minimum of is an instructive exercise with spraying order, path, distance, moving parts. Contractors can pump with confidence in all and angle maneuvers. The spraying exercises include spraying situations with the S20, handling mixtures with up 2.5 in. in a straight tunnel, at a tunnel’s end, inside a curved tunnel, (63.5 mm) aggregate and applying up to 1095 psi (7.5 MPa) or in a tunnel’s cross section. “Competition mode is also on the concrete. available…as a little competition can always improve per- For more information, please visit www.schwing.com. formance,” the company added. The new simulators have better-quality graphics and visual indicators to aid in training. According to Normet, the simulators’ visual aids include colored markers that show, when spraying, colored concrete layers indicating the thickness of the concrete sprayed (for example, a red layer is too thick, a green layer is perfect, and a blue layer is too thin). It also has a nozzle angle indicator to show nozzle distance from the wall to teach distance in spraying. After each exercise, a detailed individual-operator report, based on performance, can be printed out or transferred as a text file. The report includes pictures and graphs on the accuracy of concrete thickness, sprayed concrete quality, nozzle distance, and angle accuracy. “Trainees who have undergone Normet Academy’s sim - ulator training have shown an improvement in operator efficiency by 23 percent,” the company added.
