Crawler Drilling Rig

Product Introduction

PQZ-500L Mechanical Top Drive Drilling Rig

Mechanical transmission: reduces losses, saves a lot of pole overturning work compared to traditional vertical core drilling machines, and has a high core integrity rate. It is particularly effective in dealing with collapsed formations such as backfilling and sand and gravel. High construction efficiency and low labor intensity for workers.

Cancel friction plate clutch: AT shifting, throttle control speed, saving the tedious maintenance of clutch. Easy to operate, sensitive, and reliable;

Dual oil pump supply: single pump is used during drilling, and dual pumps are combined during lifting and lowering; Low power loss and short auxiliary time.

Hydraulic automatic opening and closing mechanism of power head: convenient for rope core retrieval, lifting and releasing casing, and other operations.

The mast comes with an angle adjustment mechanism: it can drill holes in horizontal, vertical, and inclined planes to achieve maximum versatility.

Adopting a tracked chassis: the leg oil cylinder has a stroke of 1.5m and can automatically load the vehicle, making relocation and transportation convenient.

Reserved functional interfaces in hydraulic systems: can be expanded according to the process requirements of different users
