For the upward deformation of the forklift pocket top plate, where should the measurement be taken from?

The measurement for the upward deformation of the forklift pocket top plate should be taken from the underside, undamaged area. This approach is crucial because it provides a baseline measurement that accurately reflects the original state of the plate before any alterations or deformations occurred. By starting from a section that has not been compromised, you can ensure that your assessment of the deformation is precise and valid.

This method allows for a clearer understanding of the deformation's extent and character, which can impact the safety and usability of the dry van. Accurate measurements are essential for determining whether repairs are necessary or if the structural integrity of the dry van has been compromised due to the deformation. Therefore, focusing on an undamaged area is key to obtaining reliable assessment data.
