Description
The Topdrive Mechanical Rotary Crawler Type TDMR-350-CT is a powerful, mid-range mechanical rotary drilling rig mounted on a crawler chassis. It is engineered for deeper drilling projects compared to smaller models, offering significantly increased torque, power, and capacity. Its design focuses on efficiency, with features intended to reduce non-productive time and enhance drilling performance.
Key Features
- Enhanced Power and Performance: The rig delivers a maximum output torque of 10,500 N.m and has a wide rotary speed range of 27-901 r/min.
- Efficient Drilling Mechanism: It features a mechanical power head with a long stroke of 3500mm and a speed-doubling mechanism, designed to improve drilling efficiency and reduce the risk of blockages or burning accidents.
- Advanced Hydraulic System: A double oil pump is used for oil supply; a single pump is used during drilling, while a combined flow is used for lifting, resulting in less power loss and shorter auxiliary time.
- Mobility and Transport: The crawler chassis is equipped with leg cylinders that have a 1.5m travel distance, enabling the rig to be automatically loaded for easier movement and transportation.
- Customizable and Expandable: The rig’s hydraulic system includes reserved functional interfaces, allowing for future expansion according to the specific process requirements of different users.
Integrated Centrifugal Mudpump (4 x 4)
A notable feature is the heavy-duty, Indian-made 4×4 centrifugal mudpump that is built into the rig and powered by a hydraulic motor.
