How to Calculate Scissor Lift Length
The length of a scissor jack lift 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 instance of this to show the point would be a 20-foot lift length that is featherweight made from Styrofoam which is practically weightless. It certainly would not be able to support at much of a height and would not be able to support much at all.
In order to calculate scissor lift length, determine how high in the air you need to support a platform which would support of the weight of the objects and occupants on the platform along with the platform's weight.
To be able to reach the necessary height within the weight support parameters, the number of cross sections of scissor folding supports sections which would be necessary to be extended at their full extension. Lastly, you will never want to ascend some workers up on a platform together with their materials that is on a platform supported by any kind of unstable structure since obviously any equipment which is susceptible to tipping would put individuals in a really dangerous situation.
Determine the weight of each and every scissor cross-section. This is very important to determining the weight and length of the scissor lift you would need as well as the overall stability of the machine. When fully extended, determine the angle between the scissor arms measured against the horizontal or ground level.
