XY-4-3A Core Drilling Rigs For Engineering Survey

Quick Detail: 1.The new type drill unites the tower and machine body,the tower can directly pull down the steel cages. 2.The drilling rig can be used not only in core drilling,bored construction pile, but also in water well. 3.The drill can be used in drilling technologies of reverse circulation in the hard rock stratum and ground. Description: 1.XY-4-3A Drill is improved and designed based on XY-4 drill.The new type drill unites the tower and machine body. 2.The tower can directly pull down the steel cages. 3.The drilling rig can be used not only in core drilling,bored construction pile,but also in water well.   4.Oil cylinders of the drill can raise or pull down the tower safely and quickly,move and fit the hole position conveniently. 5.The drill can be used in drilling technologies of reverse circulation in the hard rock stratum and ground. Applications: The drilling rig can be used not only in core drilling,…
