BORED PILE EQUIPMENT Telescopic Kelly bar type Earth Drilling rig NISSHA ED-series

NISSHA ED( Earth boy -Nick name ) earth drilling rigs are of “Kelly bar type” earth drilling rigs for constructing various sized bored piles (Cast-in place concrete piles) into comparatively soft stratums where no cobbles and boulders contained. There are two type of rigs, a lattice boom type (Two models) and a telescopic boom type (One model). A newly developed [High power type earth drilling rig] PDH-90 is utilized to drill into comparatively hard stratums.
	Applications Drilling bore holes for constructing various sized cast-in-place concrete piles into the comparatively soft stratums (Maximum S.P.T. N-value 50 :excluding PDH-90 ). Fleet of earth drilling rigs Ranging from φ1000 〜 3000mm in shaft diameter and 43〜62m in depth. Bell pile bucket (φ1700〜4100) Brief specifications Full-hydraulic drive, Self-propelled, Square/round type telescopic kelly bar with rotary bucket. Lattice boom type/ telescopic boom type/Leader type. Bell-pile bucket with computer monitor/recorder (Optional extra).
