KJ311(Second crushing) Top Hammer Tunnel Jumbo Drilling Rig
Features:
KJ311(Second crushing) Hydraulic Tunneling Drilling Rig is specially designed for short time and multi-station rock drilling. The drill ring is powered by diesel engine and has air compressor on board. It uses water tank for water supply and does not need extemal water, air and power supply. The drill rig can realize rapid rock drilling and rapid sites transfer, especially suitable for processing large pieces of ore in which mines that using natural block caving method.
