JDL-300 Mechanical Top Drive Core Drilling Rig

1. Introduction of JDL-300 mechanical top drive core drilling rig

JDL-300 mud/air drilling rig is a water well drilling rig that mix mud drilling rig and air drilling rig in one equipment with mechanical top head. It is a good solution to the difficulty of drilling in the soil layer for DTH rig and the low efficiency of drilling for mud rotary rig in the hard rock, gravel and pebble layer. The mud/air drilling rig adapts to various soil strata. The mud/air drilling rig is efficiency and energy saving to drill water well and geological exploration of core sample.

2. Features of JDL-300 mechanical top drive core drilling rig

(1)The rig can be equipped with a five-speed manual integrated gearbox, hydraulically separated bearings, full synchronizer shifting, high reliability and long service life.

(2)The drilling rig adopts a mechanical winch, which has a fast lifting speed and is easy to handle the bottom hole accident.
