How to Calculate Scissor Lift Length
The scissor jack lift's length is proportional to the support weight of the scissors and the integrity of the steel cross sections over the length. The scissor structures weight and length 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 which is featherweight made from Styrofoam that is practically weightless. It definitely could not support at much of a height and can not support a lot at all.
In order to calculate scissor lift length, determine how high in the air you have to support a platform which will support of the weight of the objects and occupants on the platform along with the platform's weight.
To be able to reach the required height within the weight support parameters, the number of cross sections of scissor folding supports sections that would be necessary to be extended at their full extension. Finally, you will never want to ascend a few employees up on a platform along with their supplies that is on a platform supported by any type of structure which is unstable since clearly any machinery which is prone to tipping would really put individuals in an extremely dangerous situation.
Each cross section should be weighed to determined the overall weight and length of the scissor lift as well as the overall stability of the equipment. When fully extended, determine the angle between the scissor arms measured against the ground or horizontal level.
