Also known as "power breaker", it breaks the rotating force generated by the wire rope during the lifting and lowering process, and prevents the wire rope from twisting. It is a very important tool for rotary drilling rigs and continuous wall grabs. It is used to lift and hang drills. Key components of rods, drilling tools and continuous wall grabs.
Based on the construction conditions of the rotary drilling rig and the continuous wall grab, the lifter carefully designed and manufactured by the company has the following characteristics of high cost performance, high efficiency, and high reliability:
The upper and lower joints and intermediates of the lifter are all made of high-quality alloy steel, which has undergone fine processing and strict heat treatment to make it have superior comprehensive mechanical properties, strong wear resistance and long service life.
All internal bearings use SKF bearings, with excellent performance and long life.
The sealing elements are all imported parts, which are resistant to corrosion and ageing, ensuring that the grease in the bearing cavity is not easy to leak, and the peripheral mud debris is not easy to enter the bearing cavity, so as to ensure the normal operation of the bearing.
The grease can be replaced regularly, and the grease will not deteriorate due to long-term use, thereby prolonging the service life of the lifter.
