This drill rig adopts mechanical transmission, featuring a simple structure for easy maintenance and operation.
It is equipped with a water‑brake device, which can control the tripping‑in speed, reduce wear of components such as drum and brake band, eliminate impact force of the hoisting system and ensure safe tripping.
Technical improvements have been made on the original rig design.

The drilling rig features a compact and simple structure.
All its components, including drill rods, can be transported by one 5‑ton truck.
In areas with poor traffic access, parts can be carried by manpower or pack horses along narrow trails.
It greatly saves customers’ investment in building temporary access roads and shortens the exploration construction period.

Hydraulic Oil Pump: It is a double pump.
The large‑displacement pump supplies power for the power head,
while the small‑displacement pump drives four outrigger cylinders, mast lifting cylinder and the pull‑down/hoist trolley cylinder.
Four Outriggers: The small water‑well drilling unit’s outriggers consist of hydraulic cylinders and fixing frames.

When the power supply of the main‑motor heater for the top‑drive unit is normal and the main motor is not running, the heater can be started or stopped via the [Motor Heating] switch on the door of the PLC/MCC cabinet. The operating status is indicated by the heater indicator light on the PLC/MCC cabinet. While the PLC system is in normal condition
