GP82A Jumbo drill with double layer feeder system/telescopic boom for face drilling&rock bolting
GP82A Hydraulic drilling jumbo is used for underground tunneling construction in metal mine and other underground engineering, which is suitable for small and medium sized cross section tunnels. The jumbo is designed with compact structure, small outside dimension, energy saving, advanced hydraulic rock drilling system for making it has rapid drilling speed, high efficiency, lower noise and gets efficiency development with better safety to
operators.
