BZC-350A Truck Mounted Reverse Directional Drilling Rig

BZC-350A Truck Mounted Reverse Directional Drilling Rig

The BZC-350A truck mounted rotary drilling rig is mainly mechanical driven. Most of the operating mechanisms are hydraulic driven and other parts are mechanical driven. In addition to the main operating mode of rotary drilling by rotary table and mud, this well drilling truck can be adapted to other drilling if it is equipped with drilling tool that is suitable for drilling through various strata such as clay, sand and matrix, etc.

1. Reasonable Construction Design
Due to dual slewing ring system, telescopic boom and sliding mast, the truck mounted rotary drilling rig realizes flexible movement and multi-angle changes, applicable to a variety of working conditions.
2. Comfortable Operation System
High level operation interface and convenient operation makes that wired and remote radio control system is both available on request.
3. Convenient Maintenance
Reasonable design, integrated configuration and regular hydraulic pipe lead maintenance of this well drilling truck easy and convenient.
4. Short Delivery Cycle
The delivery cycle of this truck mounted rotary drilling rig is short, just needing 90~120 days.
5. Optimal Service
Overseas customers enjoy 24 hours after-sale service a day and dispatching service. We send professional engineers there to offer technical guidance and maintenance. There is also components storage of this well drilling truck there.

1. This truck mounted rotary drilling rig is mainly applied to drill various building foundation pile holes at quaternary unconsolidated formation, gravel layer and base rock layer. It can also be utilized in industrial and agricultural well drilling.
2. This well drilling truck is applicable to deep wells engineering, building, bridge pile foundation, oilfield casing, high tension line, wind power at the bottom of the pile, geological mine, port terminals, the construction of the dam foundation, etc. It has been winning customers’ recognition and praise at home and abroad.
3. The main transmission, gearbox, winding engine, mud pump and drill tower of the truck mounted rotary drilling rig are all installed on the automotive chassis.
4. The well drilling truck adopts hydraulic system, thus the drill tower’s elevation is controlled hydraulically like the four or six landing legs. The back landing legs can stretch horizontally, which can be operated alone or with other systems at the same time. These factors improve the flexibility of this truck mounted rotary drilling rig.
5. The well drilling truck can also be equipped with hydraulic pressure device to improve high efficiency when meeting hard layer like rocks.
6. The three phase AC generating set is in your option when choosing this truck mounted rotary drilling rig. That AC generating set does benefits for night lighting and welding maintenance.
7. This well drilling truck is equipped with hydraulic power steering gearbox, which offers convenience when transferring drilling places.
8. The key feature of this truck mounted rotary drilling rig is that it can bear heavy duty construction. And the support frame is made of a solid steel beam with no poles and no tubes, which insure a stable, smooth, straight-line drilling process with no constant shaking and rocking action commonly seen on the lighter, cheaply made rigs.
9. This well drilling truck introduces the rotary drilling method, the most modern method of drilling today. It is fast and efficient and until recently it was only available in large, expensive, truck rigs.
10. The main transmission of this truck mounted rotary drilling rig is of mechanical transmission type. The drilling rod has thread and flange connecting ways.
