Distance to First Lift Line - EXO
The minimum distance between the powerhead and first block/lift line is 6'-0" for 50'-0" of system travel; the minimum is a direct ratio for any travel under 50'-0" of travel.
Example: At 25'-0" of travel, the minimum distance for the first block is 3''-0".
The distance is measured from the front flat face of the powerhead to where the lift line exits the block. This minimum applies to the first block adjacent to the powerhead, including mule blocks and head blocks.
