10 Advantages of Sino Mechaical Rotary Drilling Rigs

What is a rotary drilling rig?

Rotary drilling rigs utilise high levels of torque and rotation, with a drill bit at the end of the drill pipe rapidly rotating (between 50 and 120rpm) and boring through the rock formation. The drill bit tends to come in two primary forms: firstly, roller-cone bits, and secondly, fixed cutter bits.

Sino Mechanical's rotary drilling rigs enhances quality and productivity with  rigs. Produced in China, our machines are built in state-of-the-art production facilities and to the highest quality allowing fabrication to last through multiple repowers. Sino Mechanical has a long history with designing and manufacturing main structures of  rotary drilling rigs putting our rotary drilling rigs at the top of their class.

Features of rotary drilling rig

(1) Easy to move and highly maneuverable.

The chassis of the rotary drilling rig adopts the chassis of a crawler excavator, which can walk by itself and accurately locate the drilling hole. In addition, the rotary drilling rig can work independently. The rotary drilling rigs has strong mobility and can adapt to complex terrain. The installation and disassembly of the rotary drilling rig can be completed without auxiliary facilities. The rotary drilling rigs takes up little space and can be operated against a wall.

(2) The construction site is environmentally friendly and clean.

The rotary drilling rig uses the drill bit to excavate the soil, and the drill rod lifts the drill bit out of the hole and then unloads the soil. The amount of mud used by the rotary drilling rig is very small and is only used for wall protection, not for slag discharge. The mud used to form the hole is basically equal to the volume of the hole, and the mud can be used repeatedly after sedimentation and sand removal. Therefore, the construction site of the rotary drilling rig is clean and tidy. The pollution caused to the environment is small, and the construction cost is reduced.

(3) The hole forming speed is fast.

It turns out that traditional circulation drilling rigs or percussion drilling rigs are mostly used in the construction of foundation piles, and the production efficiency is very low. However, if the rotary drilling rig is used, the drilling speed is fast because the drill bit directly extracts the rock and soil from the hole. There is less sediment at the bottom of the hole, and it is easy to clean the hole. Therefore, the quality of the project has been fully guaranteed.

(4) The verticality of the hole is high.

The rotary drilling rig chassis is retractable and self-levelling. The verticality of the drilling tower and the drilling depth are displayed by instruments. Therefore, it is very stable when drilling, which can effectively ensure the verticality of the drilling hole and improve the drilling quality.

(5) Strong geological adaptability.

The connection between the drill bit and the drill pipe is fixed with a shaft pin, and the drill bit is easy to disassemble. The drill bit can be quickly replaced for different formations. There are three main types of drill bits for rotary drilling rigs, namely short auger bits, dredging bits, and sand dredging bits.

(6) The equipment has advanced performance, high degree of automation and low labor intensity.

The rotary drilling rig is a crawler-type fully hydraulic self-propelled drilling rig with a complete hydraulic system. Some are also equipped with advanced computer operating systems. In order to ensure the excellent performance of rotary drilling rigs, most rotary drilling rig manufacturers purchase parts and components worldwide. American Caterpillar (CAT) chassis, German hydraulic system, Japanese electrical appliances, etc. This prolongs the overall life of the rotary drilling rig. It will not affect its use due to the damage of a certain part. The integration of rotary drilling rigs, electricity and hydraulics is highly concentrated. It has a compact structure and is flexible and convenient to operate. High degree of mechanization and automation. It can move by itself in the construction site. Self-supporting mast, convenient and quick to move and align holes. The use of telescopic drill pipes saves manpower and time for connecting drill pipes. The auxiliary time is less and the time utilization rate is high.

(7) Easy to use and easy to maintain.

The main components of the rotary drilling rig are provided by the more common original component manufacturers (such as pumps, engines, motors, reducers, etc.). Accessories can be directly supported by the after-sales service of the manufacturer in the place of origin. At the same time, the rotary drilling rig has a simple structure and an extremely low failure rate.

(8) The orifice drops mud and produces less sediment.

Rotary drilling rigs use underwater conduits to pour concrete. This is a very mature pile filling process. It can avoid the adverse effects caused by mud dropping at the orifice and sediment generated during the pouring process.

(9) Applicable to various pile foundation projects.

In addition to being used for rotary drilling, the rotary drilling rig can also be used for construction such as long spirals and underground diaphragm walls. The scope of application is extremely wide.

(10) The hole backfill has less influence on the bored pile.

Rotary drilling rigs are generally equipped with an orifice casing of about 2m (if the backfill soil at the orifice is thicker, it can be lengthened). And the rotary drilling rig itself can bury the casing. In this way, the influence of the hole backfill on the bored pile can be avoided as much as possible.

What are the major components of a rotary rig?

The basic rotary drilling system consists of four groups of components – the prime movers, hoisting equipment, rotating equipment and circulating equipment – that all combine to make rotary drilling possible.

What is the main application of a rotary rig?

Rotary drilling rigs use drilling muds to lubricate, cool and clean the drilling bit, control down hole pressures, stabilize the hole wall and remove drill cuttings, thus allowing better penetration rates and higher operational efficiency.
