Counter Balance Forklift work as the name suggests.
With the front wheels being the pivot point.
Like a See-Saw from your childhood.
The load when picked up by the fork tines on the forklift as shown above as the Large crate on the right hand side of the See-Saw is Counter Balanced by all the weight as pictured on the left hand side of the see-saw, pictured as the body of the forklift, including the driver and the last heavy cast iron weight you see on the back of a forklift, termed the counter weight.
With mast show over the pivot point being the front wheels for ease of this explanation.
Now the forklift is safe and stable, as long as the force of the countering weight ( The left hand side ), is greater than the force exerted by the load carried on the tine of the forklift – The large crate on the right hand side. Pictured as the see-saw sloping and touching on the ground on the left hand side.
The back wheels are on the ground.
If the force exerted by the Large crate carried on the tine of the forklift( the right hand side ), is greater than the countering wieght on the left hand side, including the counterweight. The forklift will tip forward as shown for simplicity with the see-saw, with the right hand side touching the ground.
But as shown in the attached picture when the right hand side ( the load ) , is greater than the left hand side – The Countering Balance Weight, the forlift tips forward into a very dangerous situation.
This first sign of this begining to occur is the driver will loose steering control as the rear steer wheels come off the ground.
At this stage the load should be lowered slowly and safely to the ground as this situation and any further vertical lifting of this load by this forklift is very dangerous as it is overloaded.
Never over load a forklift.
The distance out from the load face, face of the tine, is termed the “ Load Centre “ and is another factor which will be explained in the next article:
“Load Centres – how it effects the opertaion of Counter Balanced Forklifts”
