As standard the majority of lift tables are designed with the upper platform size the same dimensions (length and width), or with slightly greater dimensions than the lower frame size. This assures that the load positioned on the lift table platform is predominantly centered during raising and lowering.
To suit various loading applications lift tables are available with platform sizes that are both longer and wider than the lower frame assembly. There are established maximum amounts of platform lengths and widths. The maximums very dependent on the various factors including but not limited to the, design of the lifting legs being utilized, the loading application details. Consideration should be given to the load that is to be placed on the platform. An evenly distributed load that is placed on the lift table platform by a lift truck is more stable and easier for the lifting mechanism to accommodate than a dynamic load that is moved or rolled onto either the end or side of the platform.
Edge loads that are positioned on the side or end of the lift table platform accommodated but have a reduced capacity from the main rated capacity of the lift. Side and edge load capacities are only based a static load. The lift is not designed to raise and lower the load at the rated side and edge load capacities. The greater the platform extends beyond the frame the lower the end or side edge load capacity rating.
In summary consideration should be given to how the product is loaded and positioned on a lift table with a platform size that is greater than the lower frame size. As well the orientation and location of the load on the lift influences the maximum load that can be accommodated. In most cases the maximum capacity of the lift is based on a centered and evenly distributed load. As the platforms sizes are increased the concern increase that the load may not centered and /or evenly distributed.
