Work Load / Stress Formula / Load Calculation

(View PDF)

The capacity at which our products can be safely used has been established through an accredited testing laboratory. This may be defined as the safe working load limit, or cable rope pulley block load calculation, or a force calculator. The safe working load limit (mechanical advantage) is the maximum load in pounds which should ever be applied, and when the load is applied uniformly and in direct tension to a straight segment of wire rope. By changing the degree of angle between lead and load angle, this also affects the stress on the block. The stress on the eye may be decreased by increasing the angle between the load and the lead angle. See chart and illustration below.

Stress Formula: (L x A = S)

Load in pounds (L) multiplied by the Angle of pull (A) equals the stress generated in lbs on the Block (S).

Safe Work Load Limit: This is the maximum load (in lbs.) which can be applied to the Block and which has been established (Load Capacity).

Questions and Answers
Q: Can I use a 1/4" wire cable instead of 3/8"?
Asked by George on 11/4/2013
A: You can use smaller diameter cable on a snatch block or block, but be aware that the life of the cable will be reduced because the cable won't fully be supported by the sheave. The degree of service life reduction will depend on the load applied, the speed, and the duty cycle of the configuration. Answer provided by:  E-Rigging Team (11/5/2013)
