Cranes are used to lift and move heavy materials on construction sites. When a crane lifts and moves a load, the distance from the load’s center of gravity to the crane’s tipping axis changes.

Mar 8, 2025 · When a crane tries to lift a load that’s too heavy, the overload creates a force that can overcome the crane’s stability, leading to a tip-over. The load may not have to be immediately over the lift capacity, but the weight combined with the boom extension can exceed the safe working load moment.

Aug 31, 2022 · Each toolbox talk includes a brief explanation of the hazard, a brief, real-life stories, discussion questions, and recaps of important safety points. The back side of each toolbox talk has an illustration of the hazard and solution, and reminders of …

Cranes are used to lift and move heavy materials on construction sites. When a crane lifts and moves a load, the distance from the load’s center of gravity to the crane’s tipping axis changes.

During a lift, the distance from the load’s center of gravity to the crane’s tipping axis changes as the boom angle changes, the boom is extended, and as the crane’s upper deck rotates to swing the load. These changes can lead to instability if the crane’s lift ca-pacity is exceeded.

Aug 12, 2024 · Enter the weight of the crane, the distance from the center of gravity of the crane to the tipping axis, and the distance from the center of gravity of the load to the tipping axis into the calculator to determine the tipping load.

However, U.S. crane manufacturers are required to perform a number of actual tipping tests to demonstrate compliance with stability margins specified by ASME B30.5 – Mobile and Locomotive Cranes.

The tipping moment describes the sum of all torques that act on a crane and can cause it to tip over. The decisive factor is the acting forces multiplied by their lever arms to the tipping edge. In cranes, this critical situation occurs particularly when lifting heavy loads.

Oct 11, 2020 · Studies show that one crane accident occurs for every 10,000 hours of use in the United States. The easiest way to prevent a tipping accident is to never lift more load than what’s stated on the load chart and make sure your crane is …

Jan 30, 2018 · Cranes can incredibly useful on construction sites. They can be utilized to pick up heavy loads and move them around. However, one of the dangers of using a crane to conduct a heavy lift is that it can tip over if you aren’t careful. Take a look at a few of the common causes of crane tipping below. Loads that are too heavy
