Detailed Description
1.Full hydraulic core drilling rig 2.drilling diameter :2.2m,drilling Depth:120m 3.good performance and high drilling efficien 产品详细描述 1.This core drilling rig adopts full hydraulic pressure drive, constant power variable loop, and makes drilling machine change rotary speed and increase Torque automatically according to the variation of stratum in the in the course of engineering construction. 2.It adopts wheel cylinder startup and electrohydraulic multiple operation. It utilizes the technique of reducing the pressure automatically to drill to ensure pore forming vertically. 3.This drill adopts the deep drilling technique of positive and negetive circulation which increases the effeciency of drilling. 4.It applies to various stratum and is the first selected equipment for the basic construction of river bridge and dock, and also applies to drilling project of high building and heavy caliber shallow well. 5.Major Diameter Drilling Equipment has double layers bottom plate. Main Technical Parameter Drilling Diameter(m) 2.2 Main Hoist Single Rope Pull(kN) 60 Drilling Depth(m) 120 Assistant Hoist Single Rope Pull(kN) 15 Max.Torque(kN.m) 60 Main Machine Weight(t) 18 Rotary Speed(r/min) 8-34 Grief Jointmm) 273×273 Main Machine Power(kW) 30×2 Passive Joint(mm) 245×20 Drilling Tower Load(kN) 400
