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 scissor structure's weight together with the length is corollaries of each other; hence, the former determines the latter for a stable scissor jack. An extreme example of this to illustrate 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 could not support a lot at all.
To be able to calculate scissor lift length, determine how high in the air you have to support a platform which will support of the weight of the objects and occupants on the platform in addition to the platform's weight.
The number of cross-sections of scissor folding supports sections which would be necessary to be extended at their full extension in order to reach the needed height within the weight support parameters. Lastly, you would never want to ascend a few employees up on a platform with their materials which is on a platform supported by any type of structure that is not stable because obviously any type of machine which is susceptible to tipping will 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 need as well as the overall stability of the equipment. When completely extended, determine the angle between the scissor arms measured against the horizontal or ground level.
