Aliva-101 spraying head for excavators

The Aliva-101 Quick Connect is a spraying head for excavators, developed for applying shotcrete with the contractor's own equipment. The spraying head is compatible with all standard quick coupler systems and can be fitted to the excavator quickly. The mounting plate can be supplied with a predefined bolted connection or welded onto any standard quick coupler. The spraying head is connected to the excavator's hydraulics and controlled by radio remote control. With the integrated dynamo, the unit needs no external power supply; alternatively, it is available for 12 or 24 VDC (5 A) without a dynamo.

Together with an Aliva rotor machine or concrete pump, the Aliva-101 becomes a complete, self-contained spraying system for both dry-mix and wet-mix spraying, and is used for slope stabilisation, excavation pits and tunnelling. The spraying head comes in two sizes: Standard for DN65 hoses at 210 bar, and the more powerful Large version for DN80 at 210 bar (DN65 at 180 bar), which also makes it possible to spray with a DN80 dense-flow nozzle. The standard version weighs 210 kg and the Large 230 kg. The hydraulic supply must be at least 210 bar and 15 l/min and at most 350 bar and 480 l/min.

According to the manufacturer, the spraying head increases safety and productivity on the construction site, since the need for scaffolding or a scissor lift is eliminated, while the excavator gains a wider range of uses. The spraying head is compatible with Aliva Converto RoboSpray for dense-flow or thin-flow spraying. Spraying also requires a separate conveying machine, such as an Aliva rotor machine or concrete pump, and the manufacturer specifies that the current user manual for the products must always be followed before use.
