Measure the location of the columns from edges of the building and compare to plans. Note that the next step may
well move the columns to get the correct position relative to the cross beam. Both these steps may be combined to
location the correct position of the columns.
You sho uld have the follo w ing in p lace:
•)The cross beams and columns are aligned in correct position
•)The cross beam is raised to remove the weight from columns (on blocks)
Read the next three sections together before bolting columns into position, the process you will follow is:
•)Align the two main columns with desired location
•)Bolt main columns in to correct location ensuring aligned with cross beams and building.
•)Pull the slave columns against the main column with snap strap
•)Align column with building and vertically with builders level, check nylon blocks are correctly aligned.
•)Fix slave columns in place

The nylon blocks in the cross beams must fit tightly against the back side of the
column. Failure to do this will cause the runways to have sideways movement.
One way to ensure the columns are in alignment is to use a snap strap to pull the columns in tight against the cross
beam as shown below. The main side of the hoist is fixed and the snap strap is used to pull the slave column up
against the nylon guide block. The snap strap is used to place constant firm pressure to hold the components
together.
