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 scissor structure's weight combined with the length is corollaries of each other; thus, the former determines the latter for a stable scissor jack. 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 would not be able to support at much of a height and would not be able to support much at all.
Determine how high in the air the platform will be raised to calculate or determine the scissor lift length needed to support the weight of both occupants and objects on the platform in relation to the weight of the platform.
The number of cross-sections of scissor folding supports sections that would be necessary to be extended at their full extension to be able to reach the required height within the weight support parameters. Finally, you will never want to ascend some workers up on a platform with their supplies that is on a platform supported by any kind of structure that is unstable since clearly any equipment that is prone to tipping would put individuals in a very 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 require in addition to the overall stability of the equipment. When entirely extended, determine the angle between the scissor arms measured against the horizontal or ground level.
