The function of the top drive single guide rail is to provide vertical sliding guidance for the top drive, playing a supporting role to facilitate the connection of the kelly and the centering of the casing during casing running. It also offsets the reaction torque from the rotating drill string during drilling, transmitting the reaction torque to the derrick base instead of the derrick itself. All parts of the top drive guide rail produced by our factory are made of high-quality structural steel and alloy structural steel. The connecting lugs are heat-treated, with high tensile strength and good weldability. Its function is to drive the drill string rotation and provide reaction torque strength. It provides a track for the top drive unit to move up and down during normal drilling and rig-up/rig-down operations.

Mechanical external card sleeve device
The top drive casing running system is a new technology for running casing. In casing running operations, the most important thing is to safely lower the casing to the bottom of the well. Our company's EMCRT external card mechanical casing running device can complete the work of connecting, lifting, lowering, rotating, and circulating, maximizing the guarantee that the casing can be normally lowered to the bottom of the well, greatly improving the success rate, safety, and efficiency of casing running operations.

Hydraulic inner-card sleeve device
The top drive casing running system is a new casing running technology. In view of the limitations of conventional casing running operations, our company has developed a safer and more efficient internal-locking casing running device. This technology can take advantage of all the advantages of top drive drilling, and can simultaneously rotate, lift, lower, and circulate mud during casing running, maximizing the guarantee that the casing can be normally lowered to the bottom of the well. It greatly improves the success rate, operational safety, and efficiency of casing running.
