Derrick (Mast)

Derrick is divided into A, K, (before the opening of), the tower type, masts and other types of packages. 
  1. A cross-section of a derrick thigh, such as rectangular or triangular pattern, carrying capacity and local stability. The use of the inter-pin connector. Derrick Low installation,  “A” crossing rely on the use of force as a whole from the winch release.
  2. K-derrick as the main "K"-type section, for the thigh Flake truss structure, the use of the inter-pin connector.  Derrick Low installation, “A” crossing rely on the use of force  as a whole from the winch release.
  3. Derrick main tower of steel structure for the pyramid, a bolt connection, the overall stability, large carrying capacity. The company also fixed offshore production platforms and the use of the pyramid derrick-up drilling derrick vessels using the dynamic, hook set up to 4890 KN.
  4. Derrick-mast when Derrick direction to the well-head tilt, on the derrick Beng rope to maintain stability and carrying capacity.
  5. Derrick is a suite of installation of the vertical telescopic derrick, my company is the development of new products in recent years.  Its characteristics are along the vertical direction will be divided into several derrick space, in which as a base of support and guidance of the paragraph, by force or hydraulic power winch the remaining paragraphs were vertical installation, to achieve the objective of saving the installation site.
