| stability triangle with C.G |
Forklift is a very safe piece of equipment. Accidents happen not because of fault in the machine its because of the operators bad practice and lack of training. In legislations, it is mentioned that whoever is using the forklift must have adequate training and must be competent to use the forklift. There are many causes of crashes however lack of awareness, training of operator tops the list. So now i am writing about the "STABILITY".
There are different kinds of forklifts such as counterbalance, reach truck, telescopic and few more however the principle of stability is similar.
In the above picture, you can see point A at the centre of the rear wheel, Points B and C at the front wheels. So Points A, B & C make a triangle which is called "STABILITY TRIANGLE". Every object has Centre of Gravity ( single point at which the object is equally balanced in all directions). Provided the centre of gravity within the stability triangle your forklift will nevert tipover. Forklift has moving parts like forks up and down, mast infront and behind. With the movement of body parts the centre of gravity moves here and there. If the operator cause the the centre of gravity moving outside of triangle, the forklift may turnover longitudinally and laterally. Other points to be noted is the higher the centre of gravity, the forklift is more unstable. So with load or without load moving position for the forklift in forks down and mast tilted back.
Different forklift has different capacities. There must be readable data-plate in the forklift. The operator should be aware of the capacity of the particular truck in different situation.
Sometimes the load would be so arranged that could be heavier in one side and lighter in another side. How do you know the centre of the gravity if the load is wooden box or cardboard box. Many of the operator are unaware of the fact that information would be provided on the box.
The above attached data-plate is for operators assessment.
Please answer in comment box.
What is the maximum capacity of the forklift truck?
What is the maximum height you can lift the maximum load?
What is the maximum load you can lift if the "load centre" is 800 mm?
Please answer and if you have any questions feel free to ask.
