◇ Note: 1. Pretightening force is spring elastic force when spring is compressed in nature state
2. Elastic force is spring elastic force when level compensator is compressed in 50% stroke, it is suggested that the actual working compressed
stroke of level compensator should not exceed 50% of its max. compressed stroke
3. Vertical load refers to the max. vertical tension that the level compensator can bear in static state
4. When the level compensator is installed horizontally, the workpiece will produce gravity perpendicular to the direction of the level compenasator,
If the gravity is larger than the horizontal load range, the spring may get stuck
