• Always anchor or hang the sheave via the clevis, never bywayofthe cover or any ancillary equipment.
• Never apply more force than the Safe Working Load (SWL)listedonthe affixed tag.
• The listed Safe Working Load is for the sheave assembly;thesafeline tension will be less.
• Attachment to other equipment with lower SWL willreducetheallowable load.

Safe Working Load
The rated safe working load (SWL) for a WTI 14” sheave is15,000lbs.(6,800 kg.), with the exception of  thosemanufacturedfor
Schlumberger.  These sheaves, as directed bySchlumberger,havea safe working load of 10,000 lbs. (4,530kg.).  Theallowableline pull will
depend upon both the SWL and the angle the lineisdeflected. If the sheave is used as a top sheave, itdeflectsthe line 180°,see figure 3.  If
the sheave is used as a bottom sheave, it deflects the line90°,seefigure 4.  Never exceed the SWL, unlessspecialprecautions aretaken in
accordance with your company’s policy.  Theseprecautionsshouldinclude, but are not limited to, clearing the rigfloor ofallpersonnel.  If
the SWL is exceeded, the sheave should be re-certified beforeitcansafely be placed back in service.

Clevis Options
Five clevis swivel assembly options forsuspending/anchoringthesheave are available:  These optionsare shown in figures 5–9 below.  The
Clevis-Eye has an opening about 2.5” X 3.3” for achainorsling.  The opening width of the Clevis -AWS is 1 3/4”withahole for a 1” pin.
The opening width of the Clevis -HLS is 1 1/4” with a hole fora1”pin.  The opening width of the Clevis-SJ is 7/8” withaholefor a 1 1/2”
