Safe Working Load

Definition - What does Safe Working Load mean?

Safe Working Load is a load-carrying tool which evaluates the maximum acceptable force needed during holding and lifting the weight. To determine the efficiency of Safe Working Load, many manufacturers provide tables to show the working under different conditions. However, the equipment gets easily affected by extreme environmental temperatures; thus, it is not widely used nowadays and is being replaced by working load limit. With the help of the device, manufacturers can calculate the load bearing limits of any product.

Petropedia explains Safe Working Load

Safe Working Load is regarded as the keystone of engineering. Its main function is to minimize the dynamic load. It is designed to lift maximum load present within the crane rated capacity under operating conditions. It is named so as it is constructed to carry the support safely. Due to plastic deformation and other stress effects, the European and ISO standards of the United States of America have stopped using the tool. The common causes of the failure of the tool are:

  • Improper lubrication
  • Dragging the rope over obstacles
  • Continued overload under severe conditions
  • Subjecting to acid fumes
