Dimension: 8209x1450x2050, Weight:11t, Steel bar diameter: 68mm, Max. height of scaling: 8529mm, Total power: 57.2kw - details see: https://www.machineto.com/hydraulic-scaling-jumbo-10319278

HT62 Hydraulic Scaling jumbo is mainly used to scale suspended rocks away from tunnel surface for tunneling construction in ferrous and non-ferrous metal mine, hydro-power station, railroad, highway engineer etc. With a folding boom plus mechanical parallel structure and rotary cylinder a hydraulic hammer, the jumbo can do scaling at any direction on face, roof, wall or ground in a tunnel. In the meantime, the jumbo's hydraulic system is designed with proportional pilot operation for making it has flexible operation and smooth movement features,. With modualr design, the jumbo has a low center of gravity, great mobility, remarkable stability, strong climb capability and smaller turning radius, thus can improve scaling efficiency and has a better safety working environment.
