How to Calculate Scissor Lift Length
A scissor jack lift's length is proportional to the scissor support weight together with the integrity of the steel cross sections more than the length. The weight of the scissor structure combined with the length is corollaries of each other; therefore, the former determines the latter for scissor jack stability. An extreme instance of this to illustrate the point will be a 20-foot lift length that is featherweight made from Styrofoam that is practically weightless. It definitely will not be able to support at much of a height and will not be able to support much at all.
To be able to calculate the length of a scissor lift, determine how high in the air you require to support a platform that would support of the weight of the objects and occupants on the platform in addition to 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 which will be required to be extended at their full extension. Lastly, you will never want to ascend some workers up on a platform with their materials which is on a platform supported by any kind of unstable structure since clearly any equipment which is prone to tipping will put people in a really dangerous situation.
Determine the weight of each scissor cross-section. This is very important to determining the weight and length of the scissor lift you will need along with the overall stability of the machine. When fully extended, determine the angle between the scissor arms measured against the ground or horizontal level.
