Product Description

Double boomer/single boomer underground multifunctional rock bolting jumbo/jumbo drill/Jumbo

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.
