How to Calculate Scissor Lift Length
The length of a scissor jack lift is proportional to the support weight of the scissors and 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 show the point would be a 20-foot lift length that is featherweight made from Styrofoam that is practically weightless. It definitely would not be able to support at much of a height and can not support a lot at all.
Determine how high in the air the platform will be lifted to calculate or determine the length of the scissor lift needed to support the weight of both occupants and objects on the platform in relation to the platform's weight.
The number of cross-sections of scissor folding supports sections which will be required to be extended at their full extension to be able to reach the needed height within the weight support parameters. Finally, you would never want to ascend a few employees up on a platform along with their supplies which is on a platform supported by any kind of structure which is unstable as obviously any kind of machine which is susceptible to tipping will put individuals in a really dangerous situation.
Every cross section should be weighed to determined the overall length and weight of the scissor lift along with the overall stability of the machine. When completely extended, determine the angle between the horizontal or ground level against the scissor arms measured.
