YPJ - 5 hydraulic feeding machine is an innovative machine recently developed for feeding concrete mix during shotcreting operation. It can be used in combination with any type of home-made shotcreting system and only needs 1 or 2 workers to manipulate for transferring all the mix from the car to the shotcreting machine in a fully mechanized way, resulting in a reduction of 50-75% labour force as compared with manual feeding; hence it makes the workers less labour-intensive and improves their working condition....
