Truck Mounted Drilling Rig

Description

Jereh truck mounted drilling rig is mechanically and hydraulically driven. The power system, drawworks, mast, travelling system and transmission mechanism of the drilling rig are mounted on the self-propelled chassis, which improves the moving efficiency greatly. Now, Jereh truck mounted drilling rig series cover the drilling depth from 1000m to 4000m and maximum static load from 900kN to 2250kN, featuring high operation load, reliable performance, excellent off-road performance, convenient movement and low operation/moving cost, and suitable for drilling operations in shallow and middle deep wells. Besides, drilling rigs for arctic, desert and highland applications are available.   

Features

  • Reasonable layout, high integration and small footprint;

  • Centralized control of electric, pneumatic and hydraulic systems with world-renowned components;

  • Designs as per API 4F specification, finite element analysis and stress test of the mast guarantee the safety effectively;

  • The chassis with excellent off-road performance and driving performances adopts heavy-duty axles, low-section tires, high-strength frame and dual braking system, durable and suitable for complicated oilfield conditions;

  • Multiple optional configurations are available such as new cab, mast automatic locking pin, centralized lubrication system of crown block and drawworks, and engine hood for various climates.
