BLOCKS: LOADING FORMULAS

Product catalog summary

Overview: This document provides a detailed analysis of the relationship between the load on a block and the deflection angle. It includes specific load factors for various angles, illustrating how the load on the block changes with the angle of deflection.

Key Sections:

1. Load and Deflection Angle Relationship: The load on the block is influenced by the deflection angle, which is the angle by which the block turns the sheet. The document outlines how different angles affect the load factor, which is the ratio of the load on the block to the load on the line.

2. Specific Load Factors: The document provides specific load factors for various deflection angles:

45° Angle: Load factor is 75%. A 100 Kg load on the line results in a 75 Kg load on the block.
90° Angle: Load factor is 140%. A 100 Kg load on the line results in a 140 Kg load on the block.
120° Angle: Load factor is 180%. A 100 Kg load on the line results in a 180 Kg load on the block.
180° Angle: Load factor is 200%. A 100 Kg load on the line results in a 200 Kg load on the block.

3. Load Factor Table: A table is provided showing the load factors for a range of deflection angles from 0° to 180°, highlighting the progressive increase in load factor as the angle increases.

Critical Information: The document emphasizes the importance of understanding these load factors for accurate load management and safety in operations involving block and tackle systems.

Catalog excerpts

BLOCKS: LOADING FORMULAS Link between the load on the block and the deflection angle: The load on the block depends on the deflection angle and the load on the line. The deflection angle is the angle by which the block turns the sheet. For a 45° angle: The load factor will be 75%. A load of 100 Kg on the line will represent a load of 75 Kg on the block. 45° 90° For a 90° angle: The load factor will be 140%. A load of 100 Kg on the line will represent a load of 140 Kg on the block. For a 120° angle: The load factor will be 180%. A load of 100 Kg on the line will represent a load of 180 Kg on the block. For a 180° angle: The load factor will be 200%. A load of 100 Kg on the line will represent a load of 200 Kg on the block.
