How to Avoid Tip-overs in Mobile Cranes

Tip-overs are one of the most common types of crane-related accidents on construction sites. Investigations by the National Institute for Occupational Safety and Health suggest that most crane operators may be unaware of the upper limits of the loads that they should be handling in certain types of cranes. Problems from overloading, improper stabilization, and wrong terrains can cause cranes to tip over or result in the arms or booms of the crane collapsing. In many cases, these tip-overs can be avoided by adhering to proper safety protocols and using proper crane safety systems. Today, we’ll discuss some of the best ways to prevent tip-overs in mobile cranes.

Using the Correct Type of Mobile Crane

There are various types of mobile cranes, each ideal for a different kind of environment and job. Choosing the right one can prevent unnecessary tip-overs and damage. Some of the different cranes to consider depending on the terrain are:

  • Carry Deck Crane: Suited to usage on roads or even terrain. Ideal for high mobility and rotation without tipping.

  • Crawler Crane: Limited rotation but can stay stable of soft and uneven terrain.

  • Rough Terrain Crane: Can’t travel on roads at all but work well on uneven terrain.

  • All Terrain Crane: Can travel on roads and work on rough terrain once stabilized.

Proper Stabilization Before Use


Stabilizing a mobile crane before you use it is standard protocol. The stabilization process involves extending the outrigger beams on the sides to provide stabilization. While the outriggers generally do a good enough job to keep the cranes upright, improper use can lead to tip-overs.


Ensuring that the outrigger isn’t unnecessarily extended, that outrigger pads are placed between the beams and the ground, and that the outriggers aren’t placed over uneven ground can help keep cranes upright.

Load Indicator Systems

Using load indicator systems can help keep track of the correct amount of load a crane can handle at any given point. This can mitigate overloading issues that cause collapses. A professional-grade load indicator keeps track of the operating angles of the crane and how much more weight it can carry. Using this can help prevent operators from accidental overloading.


At Crane Warning Systems Atlanta, we offer all sorts of crane warning systems, including a load monitoring system to help manage weight-bearing in cranes. Contact us to place your orders for overload indicators or any other safety system you need.
