When the machine performs certain tasks, the forklift's center of gravity changes.
All forklift trucks are rated by their manufacturer as having a certain safe lifting capacity and height.
It is generally accepted that forklifts can safely lift any load to its maximum rated lift capacity to its maximum lift height, which is not true.
When lifting, the forklift can be seen like a seesaw, the front axle of the wheel is like the fulcrum of the seesaw.
When picking up Tyne's load, the front end of the device becomes heavy, and the built-in balancing device negates this added weight to ensure that the device remains level and does not tip over.
The lifting capacity of the forklift at the extension height depends on the elevated load center.
The load center is the balance point of the load. At the balance point of the load, when sitting horizontally on Tyne, one end of the load abuts the bracket.
It is also assumed that the center of gravity in the vertical direction is not larger than the specified horizontal size.
The nameplate above shows the vertical and horizontal load center and lifting capacity of the unit.
The closer the load center is to the end of the tynes, the lower the unit's lifting capacity to ensure that the unit does not become top-heavy and over-balanced.
The figure above shows the drop in rated load capacity, further towards the end of the load center.
All operators must know the load center of the load they are trying to lift and their impact on the rated capacity of the equipment.
If this is not taken into account, the unit may tip over and cause serious injury to the operator, product and property.
