Interactive Load Chart Calculator

An Interactive Load Chart, uniquely designed for Matt’s Arm by Bill Griswold, is included with each kit.

This Load Chart Calculator is an Excel-based document capable of calculating safe WLL for each sheave, for each type of mount, for reaction to the tower, and for other lifting and safety factors.

This chart allows personnel in the field to input real-time information and receive calculations for safety factors, stress on the tower/tower legs, and load capacities for various sheaves and beam elevations.
