Derrick on Tianlun and rope set up the runway, the installation of hoists, winches double (3t) double rope traction, transport staff and lining materials; hoists the runway with a winch (2t) to tighten, In addition, the site symmetry at the bottom of the derrick cantilever mast for two, with two winches (3t) upgrading of materials, two separate winch (1t) Luffing operation.

井架上设天轮和钢丝绳跑道，装置吊笼，用双卷扬机（3t ）双绳牵引，运输人员和内衬材料；吊笼跑道用一台卷扬机（2t ）收紧，另外，在井架底部对称部位设悬臂桅杆两台，用两台卷扬机（3t ）提升物料，另设两台卷扬机（1t ）变幅操作。

Some large derricks are mounted on dedicated vessels, and are often known as "floating derricks".

一些大型井架安装在专用船只，也常常称为&浮动井架&。

The usage of this method simplifies the evaluation of the bearing ability of the oil derricks.

提出了将位移法应用于石油井架的承载能力评定之中，利用该种方法将使石油井架承载能力的评定测试变得更加简单。

In oilfield, downhole derricks are the main part that bears the loads in the downhole operation hoist system.

在油田起下油井管柱的各种施工中，作业井架是主要的承力构件，井架的承载性能对井下各种施工作业产生直接影响。

A torque tube assembly is mounted into the mast and supported in three (3) areas; the standard torque tube option is for a 32 m (105 ft.) telescoping mast. Other lengths and configurations are available upon request.

一个扭矩管总成被安装于井架并且在三个区域支持扭矩管；标准的扭矩管选择是用于32米(105英尺)的可伸缩的井架，其它长度和配置根据需求可选。

In order for Foremost to supply the customer with a proper torque tube that will meet their requirements, the customer is to supply Foremost with a set of drawings for the mast, which the torque tube is being mounted into, indicating the cross members which the stabilizer mounts are to be welded to.

为了Foremost向客户提供符合他们所要求的合适的扭矩管，客户要向Foremost提供一整套将要安装这套扭矩管的井架的图纸，指明那些稳定器将要被焊接安装上去的横梁，为了焊接这些稳定器到井架的横梁上，Foremost将会提供建议的焊接工艺。

The first-order optimization algorithm was used to optimize and assess the updating parameters. The simulation analysis on an in-service rig derrick was carried out using the linear buckling, geometric nonlinear and double nonlinear methods.

以某型号在役钻机井架为例，利用该方法并结合线性屈曲法、几何非线性法、双重非线性法，对其进行了仿真建模和承载性能仿真分析，确定了该钻机井架的极限承载力、破坏形式及危险部位。
