3/4” Hex Nut
Locknuts
Loft Block Maintenance
The Vortek Loft Block has sealed bearings and usually needs
minimal maintenance but the mounting hardware should be
checked and a few other simple inspections will suffice.
Check for proper torque on the beam clamp bolt and nut. This
should be 17-20 foot/pounds of torque using a torque wrench
to confirm.
There are ‘Circlips’ on both sides of the 2 axles on the loft
block. Check to make certain that the clips are seated in the
groove on the axle.
Look to see that all of the plastic covers are snapped into place.
The loft block should be free to swing in both a side to side motion and up/down to a small
extent.
Turnbuckle Maintenance
Turnbuckle maintenance requires checking the locknuts to make sure they are
tight to prevent the turnbuckle from loosening or, if your turnbuckles do not
have locknuts then make sure that they are moused.
Hoist Brake Adjustments
Occasionally the secondary mechanical brake may need some minor adjustment to alleviate
noise that could occur.
The view when the motor cover is opened so that the brake can
be adjusted.
Remove the Locknut from here, and allow cover to swing down.
The locknut on the secondary mechanical brake is
what will be adjusted.
