Product Introduction：
| Technical characteristics The A-type mast has a rectangular or triangular cross-section of the thighs, which has good load-bearing capacity and local stability. The various sections of the mast are connected by pins, installed at a low position, and lifted and lowered as a whole using the power of the main winch of the drilling rig K-shaped mast, with a "K" section as the main body and a sheet-like truss structure on the thighs. Each section is connected by pins and is lifted and lowered as a whole using the power of the main winch of the drilling rig. ● Telescopic mast, with a main body consisting of a "K" - shaped welded truss structure, consisting of two or three sections that are lifted and extended by the main winch of the drilling rig or hydraulic power; The tower type mast is mainly a tower shaped truss structure, connected by bolts, with good overall stability and large bearing capacity. There are two types of offshore use: static rigs on fixed platforms and dynamic rigs on drilling vessels; Mast type mast, with a welded truss structure as the main body, tilts towards the wellhead direction during operation, and maintains stability and load-bearing capacity through guy ropes; ● A set of derricks, with a main body in a "K" section, with the base section serving as the guide and support sections. The remaining sections are lifted vertically in sequence through the main winch or hydraulic power of the drilling rig ● Installation, saving installation land and reducing the workload of high-altitude installation operations.
