How to Calculate Scissor Lift Length
The length of a scissor jack lift is proportional to the scissor support weight along with the integrity of the steel cross sections more than the length. The scissor structure's weight together with the length is corollaries of each other; hence, the former determines the latter for scissor jack stability. An extreme example of this to illustrate the point would be a 20-foot lift length that is featherweight made from Styrofoam which is practically weightless. It definitely will not be able to support at much of a height and will not be able to support a lot at all.
To be able 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 occupants and objects on the platform along with the weight of the platform.
The number of cross-sections of scissor folding supports sections which would be necessary 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 some employees up on a platform with their supplies that is on a platform supported by any type of unstable structure since obviously any type of machine which is susceptible to tipping would put individuals in a very 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 machinery. When completely extended, determine the angle between the scissor arms measured against the ground or horizontal level.
