Engineering Heavy Lifts
When designing custom commercial vehicles, RVs, or industrial machinery, engineers cannot rely on standard catalog parts. Specifying custom gas struts requires accurately calculating gas spring force to ensure safe and ergonomic operation.
The Basic Formula
The required force (F1) in Newtons can be estimated using the following formula: F1 = (Weight x Center of Gravity Distance) / (Mounting Distance x Number of Struts) + Friction Margin. It is crucial to measure the exact distance from the hinge to the door's center of gravity, and the perpendicular distance from the hinge to the strut's mounting point.
Yueli Custom Engineering
Calculating the perfect mounting geometry and Newton rating can be complex. Yueli's engineering team assists B2B clients by modeling the kinematics of their specific heavy doors. We can manufacture custom struts with force ratings anywhere from 50N up to massive 5000N industrial cylinders.
