How to Calculate Scissor Lift Length
A scissor jack lift's length is proportional to the weight of the scissor support 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; therefore, the former determines the latter for a stable scissor jack. An extreme example of this to illustrate the point would be a 20-foot lift length which is featherweight made from Styrofoam which is practically weightless. It definitely would not be able to support at much of a height and will not be able to support much at all.
Determine how high in the air the platform will be raised to determine or calculate the length of the scissor lift needed to support the weight of both occupants and objects on the platform in relation to the platform's weight.
In order to reach the required height within the weight support parameters, the number of cross sections of scissor folding supports sections that would be required to be extended at their full extension. Finally, you would never want to ascend a few employees up on a platform together with their supplies which is on a platform supported by any type of unstable structure since obviously any type of machinery which is prone to tipping would really put individuals in an extremely dangerous situation.
Determine the weight of each scissor cross-section. This is vital to determining the weight and length of the scissor lift you will require in addition to the overall stability of the machinery. When entirely extended, determine the angle between the scissor arms measured against the horizontal or ground level.
