Final testing.
Follow these steps to confirm the hoist is installed correctly and to finalize anchor bolt locations.
Perform adjustments and settings with the hoist near ground level. Do not continue to raise the hoist if
problems arise as it is relatively easy to fix problems near ground level compared to raised runways.
1.
Visually, confirm that the locks are engaging and disengaging at the same time, adjusting as
necessary to achieve synchronous operation.
2.
The hoist should now be able to lift with the pressing of the green button.
3.
Inspect the hydraulic line to ensure not leakage at fittings.
4.
Lift the hoist a minimal amount and adjust the lift cables until all corners lift at the same time.
(Spacers are available from HAPP in the unusual case that you require extra adjustment).
5.
With the runways lifting evenly the lock engagement can be adjusted. After the latchs pass the
latch point (you will hear the four clicks) lower the hoist slowly and see that all latches engage,
if one or more does engage that corner will continue to lower while the others are held.
Inspect the adjustment and latch position on the latches to see which ones are not extending
enough. If one corner is not engaging this is typically the adjustment on that corner. If one end
is not engaging this is typically the T pieces on the safety are not aligned from end to end.
6.
Raise the hoist to release pressure of the locks. Adjust the corners and or the T piece sections
and repeat until synchronous engagement and release of locks is achieved.
7.
If the hoist is being fixed with anchor bolts check the columns are vertical and the cross beam
nylon blocks run freely inside the column. Once this has been confirmed the columns can be
fixed with the anchor bolts. Use quality masonry bits to drill the hole.
