Many inexperienced mobile crane operators may think that a mobile crane can only tip over when it has been overloaded. Such novice operators may not be aware that many factors can cause the crane to tip over even if it is carrying a small load. This article discusses some of the measures that inexperienced mobile crane operators can take to stop their cranes from tipping over at a jobsite.
Scrutinse Range Diagrams
Manufacturers of mobile cranes usually provide range diagrams that spell out which boom positions are safe when the crane is carrying different loads. Those range diagrams also stipulate the safe loads that can be carried when the boom is extended to different lengths. Always refer to those range diagrams before you start lifting loads with that mobile crane. Avoid deviating from the manufacturer's recommendations for the different ranges and loads.
Pay Attention to the Outriggers
Mobile cranes usually get some structural support from outriggers that are deployed just before lifting operations begin. Those outriggers can only serve their purpose if they are deployed correctly. For instance, the outriggers will be ineffective in case they are anchored on unstable soil. You should therefore make sure that the outriggers have been deployed correctly so that the crane doesn't become unstable to the extent of tipping over. You can use outrigger mats to stabilise the crane, for example.
Position the Crane Strategically
Another tip that you can implement is to make sure that the initial stages of each lift are done from a position where the mobile crane is least stable. In this way, you will get an early warning about a potential cause of the crane tipping over. The latter stages of the lift can be done in the direction where the crane is very stable. For instance, the initial stages of the lift can be planned to occur when the boom is at an oblique angle relative to the crane. The crane is likely to be more stable as the boom moves so that it is at a right angle in relation to the mobile crane.
Always consult more experienced crane operators, like those from Freo Group, in case you are faced with a situation where the tips above may not be sufficient to ensure safe lifting. This cautious approach will save you from getting involved in mobile crane accidents early in your operator career. The veteran operators will guide you and help you to become a better crane operator.Share

Heavy construction equipment can be quite expensive to replace, so it's important to maintain it properly. That involves doing some regular maintenance according to the correct service schedules as well as making sure that your operators know how to operate the equipment correctly. If you maintain your equipment, this maintenance can end up saving your business a lot of money down the track when you can extend the usable life of the equipment that you rely on. This blog has some tips on how you can easily maintain heavy construction equipment, including how you can train operates to extend lifecycles with sensible machine operation.
