How to Calculate Scissor Lift Length
The length of a scissor jack lift is proportional to the weight of the scissor support along with the integrity of the steel cross sections more than the length. The scissor structure's weight together with the length is corollaries of each other; thus, 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 which is pretty much weightless. It definitely can not support at much of a height and will not be able to support much at all.
In order to calculate the length of a scissor lift, determine how high in the air you need to support a platform that will support of the weight of the objects and occupants on the platform in addition to the weight of the platform.
In order 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. Finally, you would never want to ascend a few workers up on a platform with their materials which is on a platform supported by any kind of structure that is not stable because obviously any machinery which is susceptible to tipping will really put people in an extremely dangerous situation.
Determine the weight of each scissor cross-section. This is vital to determining the length and weight of the scissor lift you would need along with the overall stability of the machinery. When fully extended, determine the angle between the scissor arms measured against the ground or horizontal level.
