Introductions

Wireline coring drill rig, type HCDU-5 is applicable in wireline coring diamond drilling techniques. It is developed independently by us on the basis of similar equipment for the purpose of wireline coring diamond drilling. Besides, it is a geological equipment suitable for use in medium-deep hole coring drill.

Features
  • Large lifting ability of the main winch, high gear lifting force reaching single rope 8.3 tons, maximum lifting force reaching 12 tons.
  • Large pulling force of the feeding cylinder, the speed adjustment and pressure control integrated together in the feeding system, maximum feeding pulling force reaching 12.5 tons.
  • Wide range of adjustment of the rotary speed, integration of mechanical and hydraulic speed control, maximum speed reaching 1240rpm.
  • Reasonable overall layout, the mast is arranged along the axis of the drill, the stable performance of the machine is enhanced.
  • Long spindle stroke which increases the drilling efficiency in the meantime reducing the occurrence of accidents in the drilling works.
  • Adopt modular design and hence easy to be shifted and easier to be selected to suit our customers' preference.
