Description of Scaling Jumbo :

QM1 scaling jumbo is a special equipment for rock scaling and risk elimination in small and medium-sized tunnels. It gets four-wheel wet braking, articulated chassis with small turning radius, strong traffic capacity. The equipment realizes mechanization of scaling operation. It is mainly applicable to underground mine and various underground construction tunnels, quickly and effectively remove the unstable rocks on roof and two sides of the tunnel face that are easy to fall, collapse and relatively hidden after blasting operation, so as to prevent the occurrence of rock falling accidents, To ensure the safety of operators and machines. Two models are set according to the needs of customers, QM1 with a reaching height of 6m and QM1L with a reaching height of 8m.
