BLOCK REEVING

Some portion of a wire ropes strength—when operating over sheaves—is expended in turning the sheaves and in flexing. This lost strength is not available to lift the load, and in a multi-part tackle block system this loss factor can be significant.

This load on the lead line (fast line) under static (no-movement) conditions can be readily calculated if the load is divided by the number of parts of line as expressed in the following formula.

A. ONE-PART LINE B. TWO-PART LINE C. THREE-PART LINE D. FOUR-PART LINE E. FIVE-PART LINE

Fast line load = Total load (incl. slings, containers, etc.) No. of parts of line

For example, in a four-part system to lift 6000 lb. the lead line will equal: 6000 or 1500 lb. 4

KS METHOD OF REEVING MANILA & WIRE ROPE BLOCKS

Methods of REEVING TACKLE BLOCKS vary with the application and purpose for which they are to be employed, especially on Heavy Lift Cargo Booms, Cranes, etc. where Block with 4 Sheaves or more are required, in which case a number of Lead Blocks have to be considered. We will be glad to consult with you on this matter.

For Example: To figure ‘‘Parts of Line’’ required when Load Lifted ‘‘L,’’ and Line Pull ‘‘P’’ are known.

LP

32,000 lbs (Load Lifted ‘‘L’’) 6,000 lbs (Line Pull ‘‘P’’)
