The vertical distance between the highest and lowest working positions of the spreader is called

The vertical distance between the highest and lowest working positions of the spreader is called stroke, also called lifting distance or lifting height. Travel refers to the distance that lifting equipment or tools can move in the vertical direction, and is usually used to describe the vertical moving distance of cranes, elevators, lifts and other equipment.

In practical application, the size and accuracy of the stroke have an important impact on the safety and efficiency of lifting operation, which needs to be reasonably selected and designed according to the actual working environment and requirements.

In industrial production and building construction, travel is a very important parameter in hoisting operation, and it is usually necessary to select suitable equipment and tools according to actual needs and environment. For cranes, lifts and other equipment, the size and accuracy of travel are usually important considerations in equipment selection and design, which need to meet the requirements of safety, stability and efficiency.
