CRAWLER DRILLS are Encumbered with extra- features that make them the finest on the market:

The D.T.H. Hammer version of the versatile crawler drill is equipped with pneumatic D.T.H. Hammer with air rotation unit qhich is well known for its simplicity & reliability. It consumes less air & delivers all round performance. Suitable for the hole size 102-114mm(41/2") Depth 36Mtr the top-D.T.H. Hammer is the first choice for quarrying & consolidation jobs.

TOP-HAMMER VERSION: The Top Hammer version of the verstile Crawler Drill is equipped with pneumatic rock drills KSC120F which is well known for its simplicity & reliablity. It consumes less air & deliver all round performance. Suitable for for hole sizes 48-76mm, Depth 45 Mtr.,the Top Hammer version is the first choice for quarrying, trenching & consolidation jobs.

Control Panel : Centralized Sensitive controls Pneumatic and hydraulic with auto feed arrangement is so arranged to ensure ease of operation which reduces operator fatigue

Track & Traction Drive : Rugged Durable Overlapping steel track pads ar made to with stand punishment and keep right on going. Mechanical track oscillation are provided Allowing the track to flex up on either side providing positive ground contact while tramming over rough terrain.

Tramming Power is supplied by two powerful 9.0 H.p radial piston type air motor coupled to self braking spur worm combination reduction gearbox and chain drive on either side. This is enough to tram the K-323 with its compressor in tow right to the job site.
