Description and principle of operation

The MPCS 4 shotcrete installation was made using the most modern technical knowledge in the field of design and maintenance safety and is another of the series in the products of the Stroystav CM company. It is intended for builders of transport structures, tunnels, as well as for large metallurgical workshops, especially for steel mills with continuous casting of steel.

The massive design and placement of individual components allow for comfortable work and increase the reliability of the equipment.

The MPCS 4 shotcrete installation is designed for feeding and applying dry concrete mixtures to tunnel walls, during the restoration of bridge supports, for waterproofing concreting works, for delivering and applying heat-resistant concrete to the walls of a steel furnace, ladle, which may be at operating temperature or may be cooled.

The MPCS 4 shotcrete unit is equipped with massive wheels and a front steerable wheelset, which allows it to be manipulated conveniently. If the MPCS 4 shotcrete installation is used in a stable workplace, it can be installed without a running gear with a device for manipulation using a high-lift trolley.

The MPCS 4 shotcrete installation is loaded with a mixture from bags or with the help of an auxiliary structure, from high-volume bags (such as "Big-Run").

The installation can be controlled from a place intended for maintenance personnel, or by remote control by an employee servicing a cement cannon up to a distance of 100 m.

The principle of operation
The mixture supplied in bags should be loaded into the funnel. The funnel is equipped with a vibrator, which contributes to a good loading of the mixture into the chambers of the dosing turnstile. By rotating the turnstile, the chamber filled with the mixture enters the position in which compressed air pushes it into the ejector. In the ejector, the mixture is pushed with the following air through the transport hose into the cement gun, where the dry mixture is moistened with sprayed water and after that the mixture is thrown out with concrete to the treated place. The mixture is applied at high speed, which allows to obtain excellent adhesion on the treated surface.
