Items needed:
Qty
Description
4 Lifting Chains
4 Drive Chains (the drive chains will be shorter than the lifting chains)
4 Counterweights
4
Lifting Chain Master Link Assemblies
4 Drive Chain Master Link Assemblies
1. Familiarize yourself with the drive base layout on top of the lift, ensure that all
components are present and oriented as shown in Figure 28.
2. Install drive chains between the 17-tooth (approx.) double sprockets on the main drive
shaft and the 48-tooth (approx.) sprocket on the top of each mast beam. Each drive
chain should engage each drive chain tensioner as shown in Figure 30.
3. Find the four (4) equal lengths of lifting chain, lay out on a clean surface.
4. Raise each chain up to the drive base, lower one end of the chain down the mast beam
to the carriage upright and wheel guides. Lay the other end up and over the sprocket
on the top of each mast as shown in Figure 31.
5. Make sure that the carriage is level at the lower level before connecting one end of the
lifting chain to the wheel guide with the hardware listed & provided (refer to Figures
32a and b).
6. With all chains in place, make sure that each of the chains have the equal number of
links to the top of sprocket & that they are equally tight by lifting them over each drive
sprocket and the free end down into its respective counterweight tubes.
7. Break the free end of each chain at 12-13 inches below each sprocket (again, with the
carriage resting on the ground).
8. Using the hardware provided, attach a counterweight to the end of each chain as
shown in Figure 33.
9. Slide each counterweight into its guide tube.
10. When complete, the lifting chain path should look like that shown in Figure 31.
