Fork lift truck Lateral stability  

Fork lift truckMore fork lift stability accidents happen when trucks tip over in a sideways direction than when they tip forwards. The golden rule is STAY ON THE TRUCK AND DON'T JUMP!

Nowadays seatbelts are supposed to be fitted to many types of truck and you can click here to find out the regulations about these. If a truck is fitted with a seatbelt it makes good sense to use it always.

When considering sideways or lateral stability it's useful to use a car as an analogy. Comparing a fork lift to a car we have the following:

  • There is no suspension to take care of the bumps on a fork lift
  • A truck is relatively narrow in width
  • A truck is relatively high compared to a car especially when the load is raised

To make sure a truck doesn't overturn, operators should observe the following rules:

  • Avoid turning at excessive speed and note that it's worse when unladen!
  • Do not turn with an elevated load. If the job can't be done properly, a full risk assessment should be carried out by management.
  • Cross obstructions such as gullies and the like diagonally at an angle of about 45 degrees and very slowly
  • Check tyres at the start of every shift. Note that a pneumatic tyre deflating can cause serious lateral stability problems.
  • Do not elevate a load with full rear tilt applied.
  • Watch out for potholes, rubbish on the floor and other floor obstructions
  • Make sure that loads and forks are not offset
  • Centralise loads
