Hoist Brake Adjustments
Occasionally you might need to adjust the secondary mechanical brake to alleviate noise that could
occur. Perform the following procedure to adjust the secondary brake.
1:
Remove the motor cover to gain access to the brake.
2:
With the cover removed, loosen the locknut on the gearbox shaft until the bronze bearing and
belleville washers spin with a small amount of finger pressure.
3:
Run the hoist UP approximately two freet so that the secondary brake is engaged.
4:
Tighten the locknut to 22.5 Nm (200 in/lb) with a torque wrench.
5:
Run the hoist back down to see if the noise is gone.
6:
If there is still noise, tighten the nut 1/8 of a turn and then run the hoist down again.
7:
Repeat steps 5-6 until the noise is gone.
CAUTION:
Loft Block Maintenance
The Vortek NXT loft block has sealed bearings and usually needs minimal maintenance, however it is
still important to inspect other components of the hardware.

Verify the beam clamp bolt and nut are properly torqued at 23-27 Nm (17-20 ft/lb).
2:
Ensure the plastic covers are snapped in place.
3:
Check that the loft block is free to swing both side-to-side and up-down to a small extent.
Note:

Do not tighten the locknut to the point where there is no more adjustment
available.
If you are using non-ETC loft blocks, refer to the manufacturer's maintenanace or
service recommendations.
