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 weight of the scissor structure together with the length is corollaries of each other; therefore, 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 pretty much weightless. It certainly could not support at much of a height and will not be able to support a lot at all.
In order 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 in addition to the platform's weight.
In order to reach the necessary 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. Lastly, you would never want to ascend a few employees up on a platform with their supplies which is on a platform supported by any type of structure that is not stable since clearly any type of equipment which is susceptible to tipping will put people in an extremely dangerous situation.
Determine the weight of each and every scissor cross-section. This is vital to determining the length and weight of the scissor lift you would require as well as the overall stability of the machine. When completely extended, determine the angle between the scissor arms measured against the ground or horizontal level.
