Semmco Alpha 20

Features

Alpha 20 is a robust shotcrete sprayer, diesel hydraulically driven with a large concrete pumping capacity, the main characteristics of this equipment is the high reliability and the easily and low cost maintenance. The boom is designed for an optimum application of wet shotcrete, with a maximum reach of 7 meters. The concrete pump BS7622 has been specially engineered to work with shotcrete and has a theoretical capacity of 18 m³/h.

The analog additive dossing system based on a peristaltic pump hydraulically driven, the additive tank is done in stainless steel 400 L capacity, this combination ensure a long life time of the dossing system even with the most corrosive admixtures. The spraying process can be done from the radio remote control unit, which let the operator control all the functions involved on the spraying process at a safe distance.
