In accordance with analysis of hook load(160t) of MR-7000 workover rig and designed drilling tools friction in well S-18,the load capacity and torque ability of the workover rig can meet the need of lifting ability of normal tripping and drilling operation,and the servicing rig has acertain capacity of treatment downhole accident.

Predicting and controlling the hook load and casing running depth in the process of completing extended reach wells is one of the key factors to ensure the completion to be successful.

Such as maximum hook load and load store coeficient,power dispose of diesel engine,efficiency,power utilization ratio and power factor,the rotate direction of mud pump ete.

The effects of recombine human growth hormone on mandibles maximum load in ovariectomized rats with changes of stress;

Based on the principles of mechanics of materials and fracture mechanics,explicit formulas,figures and tables of normalized maximum load,its corresponding deflection and stiffness are obtained for three-point bending specimens of brittle materials.

With the load datum time, maximum load s probability distribution can be estimated during the structure in service, thereby we can assess reliability of structure in service.
