Feature:
Heavy Load Chassis
With time-proven and robust design chassis,this rig delivers high reliability with heavy loads.Also the classic direct hydraulic control system makes operating and maintenance easier.
Versatile Bolting Head
Bolting head can be customized for using split set bolts only,or resin bolts only,or combined both bolts.The bolts handler capacity for split set is 10 pcs,resin is 10 pcs,and combined both is 6 pcs split set+ 6 pcs resin at the same time.Also resin conveying system and mesh handling arm are equipped on bolting head,by working together they can complete the meshing,drilling and bolting processes consistently and quickly.
