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).
Drilling bore holes for constructing various sized cast-in-place concrete piles into the comparatively soft stratums (Maximum S.P.T. N-value 50).
Ranging from φ1000 ～ 3000mm in shaft diameter and 43～62m in depth. Bell pile bucket (φ1700～4100)
