How to Calculate Scissor Lift Length
The scissor jack lift's length is proportional to the scissor support weight as well as the integrity of the steel cross sections over the length. The scissor structures length and weight are corollaries, meaning that the former determines the latter for a stable scissor jack. An extreme example of this to illustrate the point would be a 20-foot lift length which is featherweight made from Styrofoam that is pretty much weightless. It certainly will not be able to support at much of a height and can not support much at all.
In order to calculate scissor lift length, determine how high in the air you need to support a platform that will support of the weight of the objects and occupants on the platform as well as the platform's weight.
The number of cross-sections of scissor folding supports sections that will be required to be extended at their full extension in order to reach the needed height within the weight support parameters. Lastly, you would never want to ascend some employees up on a platform along with their supplies that is on a platform supported by any type of structure which is unstable because obviously any machine which is susceptible to tipping will put individuals in a really dangerous situation.
Determine the weight of every scissor cross-section. This is very important to determining the weight and length of the scissor lift you will need in addition to the overall stability of the machine. When completely extended, determine the angle between the horizontal or ground level against the scissor arms measured.
