2)Derrick masts to the work derrick wellhead direction tilt
Introduction:
Derrick divided into A, K, (open type), tower type, such as masts and packaged-type.
· A thigh-derrick with rectangular or triangular cross-section, such as type, capacity and local stability. The use of inter-connecting pin. Derrick low installation, use Renzijia rely on the power winch from the overall release.
K-derrick main "K"-type section, thigh patch truss structure, the use of the inter-pin connection. Derrick low installation, use Renzijia rely on the power winch from the overall release.
Derrick main tower of steel structure for the tower using bolt connection, the overall stability and the carrying capacity. The company also manufactures fixed offshore platform derrick and the pyramid-up drilling derrick vessels use the dynamic, hook up to 4890 contained KN.
Derrick masts to the work derrick wellhead direction tilt, he showed a long rope on the derrick to maintain the stability and load-carrying capacity.
Derrick is a suite of vertical telescopic derrick installed, the company is the development of new products in recent years. Its characteristics are along the vertical direction of space will be divided into several of the derrick, as a base of support and guidance of the paragraph, by force or hydraulic power winch the remaining paragraphs were vertical installation, saving land for the purpose of installation.
