Care must be taken to maintain the center of gravity within the stability triangle of the forklift by not lifting more than the maximum allowable given the load center.
Forklift center of gravity stability triangle.
Understand the stability triangle an unloaded lift truck s center of gravity where the weight has equal concentration typically is higher than that of a personal vehicle.
So long as the combined centre of gravity of the vehicle and its load remains within this triangle the vehicle will be stable.
A forklift can overturn sideways if the center of gravity leaves the stability triangle on either of the two sides.
What do you to explain the complex concept of the danger of tipping over a forklift without risking a life.
Load center forklift stability triangle.
When the load is lifted the center of gravity moves forward.
The lateral stability affects carrying a load and it shifts when taking a corner too fast or making a sudden stop.
The two front wheels b and c and the pivot point of the rear axle a.
Always check your data plate for the information about the distance from the heel to the back of the forks outwards to the center of gravity.
The reason that the centre of the rear axle is used is because the axle is only fastened to the chassis of the truck in the centre and is allowed to articulate in the case of four wheel trucks.
A forklift can tip over sideways if the center of gravity leaves the stability triangle.
You can also see on some forklifts how much you can lift and at what load centers.
The load has its own center of gravity and once it s picked up a combined center of gravity between the load and truck is established.
As such it s important to keep the center of gravity as close to the middle of the stability triangle as possible.
3d animation of course.
For this reason it is important to keep the center of gravity as near as possible to the center of the forks remembering that the center of gravity may not be the geometric center if the load has irregular weight distribution.
Since the counterbalance weight doesn t move the weight operators must be concerned with the load s weight.
The forklift s center the lift truck also has a center of gravity which shifts once the truck picks up a load.
But if the forklift is put in motion or sits on a sloping.
This triangle is measured from the centre of the rear axle to the centre of the front wheel tyres.
When viewed purely in two dimensions as in fig 1 the forklift stability triangle can be seen as the joining of three points.
