Performance Characteristics
● The original made in USA powerful Cummins engine is selected to integrate with the core technology of TYSIM in electronic control system and hydraulic system to maximize its working performance.
● The whole series of Tysim products have passed GB certification and EU EN16228 standard certification, better dynamic and static stability design to ensure construction safety.
● TYSIM makes its own chassis specially for rotary drilling rig to perfectly integrate the power system with the hydraulic system. It adopts the most advanced load sensing; load sensitivity; and proportional control hydraulic system in China, making the hydraulic system to be more efficient and energy-saving.
● Perfectly matching the increased pressure with the power head torque for better efficiency when drilling rock.
● The power head is designed with an extra option for drilling rock to reduce the operation intensity of the operator, and greatly enhance the ability for drilling rock.
● Driven by double rotary motors to attain powerful rotary braking performance and to ensure stability and safety when drilling at extreme drilling torque.
● Front positioned single drive main winch with only two layers during operation to greatly improve the service life of the wire rope.
● The strong rotary braking performance provides stability and safety when drilling in extreme construction conditions so as to ensure the vertical degree of the pile.
● The height is only 8 meters in operational status, when matched with power head with big torque, it can meet most of the jobsite conditions with low clearance construction requirements.
