The Hazards Associated With Lifting Equipment

Lifting Equipment and Gears are mechanized devices used for lifting heavy materials in the construction and manufacturing industries. There are many benefits of using Lifting Equipment. Time is saved vis-à-vis when a task is performed physically. There is a safeguard against injuries to workers. Man-hours are saved. Thereby, increasing the productivity and efficiencies of the workers and ensuring timely deliveries of products. The project completion time can be reduced and managed well. There are different kinds of Lifting Equipment like Hand-operated/ power-operated cranes,  winches / hoists, different kinds of Slings, wire ropes, shackles, eyebolts, gin wheels, pulley blocks, goods lifts, elevators, lifting rigs, forklift trucks etc. Possible hazards associated with Lifting Equipment These equipment are heavy machinery. The companies should be well aware of the maximum capacity of lifting loads of each of the equipment they have. They should ensure that the equipme...

How do you calculate safety factor for lifting ?

The safety factor for lifting is the ratio between force applied to a component in a system, and the minimum breaking strength of the component. The safety factor is calculated by dividing the minimum breaking strength of the gear by the maximum force that can be supported by the lifting gear. If the safety factor is less than 1, it implies that the force exceeds strength, and the component would fail. When it comes to the estimation of maximum force, riggers can use maximum static force or maximum dynamic force. The former refers to the force when the system is motionless, and the latest refers to the force generated when a falling load is caught. Safety factors are calculated based on status loads. This makes it easier to calculate static forces in the field. Rescuers ensure that systems can accommodate dynamic loads using sufficiently high safety factors. For instance, a component with a static safety factor of 10:1 encounters dynamic events that generate forces five times more than...
