1. It is equipped with forehead cylinder, through which the pulley-yoke can automatically fold the mast, so as to reduce labor intensity and improve work efficiency;

2. Main winch adopts single-motor reducer drive, which can ensure the stability of strong pulling and rapid lifting, so as to realize high working efficiency of main winch;

3. Rear-placed main winch (Patent No.: 200620135077.0) adopts lengthened-type large-diameter winding drum, which realizes a single-layer winding of steel wire rope and greatly improving the service life of steel wire rope;

4. This rotary blasthole drill rig uses the most advanced electronic leveling device which can switch between manual operation and automatic operation and is capable of real-time monitoring the mast and carrying out automatic adjustment to ensure the mast is always in the vertical state during construction operation, and this can effectively ensure the pile-hole verticality meets the requirement of the engineering;
