- Product Description
- EKD-3A Product Abstract:1. Machine type: underground tunnel drill rig2. Brand: iAEG3. Model: EKD-3A4. Drilling depth: φ55x1500 mm drill rod, 300m φ71x1500 mm drill rod: 200mEKD-3A Product Introduce:This full hydraulic underground drilling rig is mainly applied in the fields of coal, geology, metallurgy, and engineering.It is used for drilling big diameter gas drainage hole and water injection hole in mines, gallery and coal mine; big diameter horizontal hole of surface engineering working.Also for big diameter roller bit drilling, hard tungsten carbide drilling and percussion rotary drilling.EKD-3A Product Features:1. It is separate in structure, small in size, light in weight, flexible in movement and convenient in operation.2. The hydraulic pump is driven by explosion-proof electric motor through operating system, then the hydraulic pump enforces hydraulic motor to make drill head rotate, and at the same time, the movement of drill head is realized by oil cylinder & chain double speed mechanism.3. Hydraulic chuck can satisfy the function of shackles and power-off protection.4. The sliding and extending & retracting function of the mast makes it convenient for the bottom of mast to touches the ground or platform, thus the drill rig will be more stable.5. The swinging arm and mast can do luffing movement, which satisfy the request of multi-angle drilling.6. The range of spindle rotating speed is wide and the torque is large.EKD-3A Main Technical Data:
