• never apply more force than the safe working load (swl) listed on the affixed tag.
• the listed safe working load is for the sheave assembly; the safe line tension will be less.
• attachment to other equipment with lower swl will reduce the allowable load.
• always use a hand guard when the sheave is used around personnel.
• always make sure the sheaves are properly maintained【敏感詞】properly rigged.

safe working load

the rated safe working load (swl) for a wti 14” sheave is 15,000 lbs. (6,800 kg.), with the exception of  those manufactured for schlumberger.  these sheaves, as directed by schlumberger, have a safe working load of 10,000 lbs. (4,530 kg.).  the allowable line pull will depend upon both the swl【敏感詞】the angle the line is deflected.  if the sheave is used as a top sheave, it deflects the line 180°, see figure 

3.  if the sheave is used as a bottom sheave, it deflects the line 90°, see figure

4.  never exceed the swl, unless special precautions are taken in accordance with your company’s policy.  these precautions should include, but are not limited to, clearing the rig floor of all personnel.  if the swl is exceeded, the sheave should be re-certified before it can safely be placed back in service. top sheave
