A forklift tip-over can have terrible consequences. There are several causes of Forklift Tip-Overs. Vehicle and stock damage are almost guaranteed, but in worst case scenarios accidents of this kind can result in serious or even fatal injuries. But, if you and your operators understand the causes and how to avoid them, you can dramatically reduce the risk of this happening on your site. To help, we’ve highlighted four common causes, as well as some top tips that can be easily applied to reduce risk in each case.
According to recent BITA analysis of 2016–2018 RIDDOR reports, the most common contributory factor in forklift truck tip-over events was the handling of live loads, or those suspended below the forks, e.g. bulk bags or loads hanging from an attachment, as opposed to loads sat on pallets. More than 1 in 5 reported truck tip-overs involved these types of loads, no doubt due to their unique effect on load centre of gravity and, in turn, truck stability.
Unlike a standard palletised load, which is more likely to remain stationary in transit, a suspended or live load is far more susceptible to movement. If the operator does not understand and accommodate this, the increase in momentum can change the load centre of gravity so much that it causes the truck to tip.
To reduce risk:
HSE statistics revealed turning with elevated loads as being the biggest single cause of fatalities in forklift accidents in the UK. It’s a common contributor towards tip-overs because turning at the same time as raising or lowering a load causes greater force to be applied to one side of the truck than the other, reducing stability. Not to mention the fact that laden trucks become less stable the higher the load is lifted, so adding an additional manoeuvre at this point can only reduce stability further. Though turning with an elevated load is often perceived as a time saver, the delays, costs and consequences of a tip-over far outweigh any minor gains to be made.
To reduce risk:
BITA’s analysis of RIDDOR reports suggests that between 2016–2018, traversing a slope or uneven ground accounted for 17 percent of lift truck tip-overs. Driving over slopes can only be done safely in two directions on a forklift truck, straight up and straight down, never across the incline or on a diagonal. To do so affects the lateral stability of the truck as the weight falls to one side of the vehicle, and can cause it to tip. The same principle applies when a truck travels over uneven ground; the weight becomes unevenly distributed and, combined with the momentum of the moving truck, can result in a tip-over.
To reduce risk:
This caused 10 percent of truck tip-overs and 10 percent of all reported accidents between 2016 and 2018, as well as having the second highest link to fatality. Not only can insecure loads fall and injure those in the vicinity, the sudden loss can also affect stability and cause the truck to tip over. Whereas if a truck is overloaded, at ground level this can cause the back wheels to lift, or if overloaded at a height, the forklift might tip forward, potentially into racking which will cause further damage.
To reduce risk:
These principles of safe operation should all form part of your team’s Forklift Operator Training. By reiterating the key points from this guidance and regularly monitoring their operating standards, you can significantly reduce the risk of a forklift truck tipping over on your site.
