Pneumatic handheld rig ZQS-55 / 2.5S ZQS-55 / 2.5S impetus for compressed air, and thus avoid the use of hand-held electrical equipment Face potential safety problems. The original electric drill (coal machine) used in drilling, are applicable to the pneumatic drill, drill construction increased by more than 50 percent efficiency. Handheld pneumatic bolt rig is mainly applied in coal roadway, bolting and blasting holes and a half before the fight greet coal roadway side to help. Weighs only 1/3 electric drill with the performance, can greatly reduce the labor intensity.
