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 scissor jack stability. An extreme example of this to show the point will be a 20-foot lift length which is featherweight made from Styrofoam that is practically weightless. It certainly will not be able to support at much of a height and would not be able to support much at all.
To be able to calculate scissor lift length, determine how high in the air you require to support a platform which would support of the weight of the occupants and objects on the platform along with the weight of the platform.
In order to reach the necessary height within the weight support parameters, the number of cross sections of scissor folding supports sections which will be necessary to be extended at their full extension. Lastly, you will never want to ascend some employees up on a platform together with their supplies which is on a platform supported by any kind of structure that is not stable because clearly any kind of equipment which is prone to tipping would put individuals in a very 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 in addition to the overall stability of the machine. When fully extended, determine the angle between the scissor arms measured against the horizontal or ground level.
