CHAIN

Chain is to be kept clean and lubricated (See LUBRICATION, page 9). Visually check chain every time hoist is used. Hoist must not be operated when chain is twisted or kinked. An important phase of hoist maintenance is chain inspection. Check individual links and check for chain elongation.

1.Check the chain for overall wear or stretch by selecting an unworn, unstretched length of chain (at the slack end for example). Let the chain hang vertically with a light load (about 20 pounds) on the chain to pull it taut. Use a large caliper to measure the outside length of a convenient number of links (about 12"). Measure the same number of links in a used section of chain and calculate the percentage increase in length of the worn chain.

2.If the length of the worn chain is more than 1½% longer than the unused chain (0.015" per inch of chain measured), then the chain should be replaced. If the chain is worn less than 1½%, check it at several more places along its length. If any section is worn more than 1½%, the chain should be replaced.

The chain used on this hoist has very carefully controlled dimensions and has been heat treated. Do not attempt to substitute other manufacturer’s chain.

Chain Replacement with Chain in Hoist

Refer to Figures 3 & 4.

1.Run hook up to its top limit.

2.DISCONNECT HOIST FROM POWER SUPPLY and remove the electrical cover.

3.Using a screwdriver, pry the spring guide plate out of the slots in the limit switch nuts (See Figure 3). Turn the slotted nut nearest you, the gold nut, back to about the center of the threaded screw. Do not disconnect the wires from the limit switches.

4.Remove the load block assembly from the old chain. On double-chained hoists detach the chain from the chain support and pull it through the load block assembly (See Figure 4).

5.Make a “C” shaped chain link by grinding through the end link on the load end of the old chain.

6.Using the “C” link, attach the new chain to the load end of the old chain. Be sure that the welds of the upstanding links of the new chain will face outward from the load sheave.

The end links must be oriented for attachment to the dead- end screw and the chain support (double-chained only) without any twist in the chain.

7.With the electrical cover off, connect the hoist to the power supply. Be sure that the green ground wire is properly grounded (See INSTALLATION, page 4).

8.Carefully jog the “UP” button and run the joined pieces of chain into the hoist until about 15" of the new chain comes out the other side.

9.DISCONNECT HOIST FROM POWER SUPPLY.

10.Remove the “C” link and the old chain. Remove the chain stop from the old chain by prying off its retaining ring with a flathead screwdriver. If attached, remove the old chain from the side of the hoist by removing the dead-end screw and washers (note placement of washers).

11.Attach the chain stop to the slack end of the new chain by capturing the 12th link with the two stop halves positioned with their tapered ends pointing towards the hoist. Slide the sleeve over the halves and attach the retaining ring. If you are not using a chain container, attach the slack end of the new chain to the side of the hoist using the dead-end screw and washers. With factory supplied hardware there should be six washers between the hoist and chain link and two washers between the chain link and screw head. DO NOT allow twists in the chain.

12.Adjust the lower limit switch (See ADJUSTING LOWER LIMIT, page 8).

13.Attach the bottom block on single-chained hoists using a new load block screw (See Figure 20). On double-chained hoists, feed the chain through the load block (welds of the upstanding links will be in towards the sheave) and fasten the end of the chain to the chain support using a new chain support pin (See Figure 20). Be sure there are no twists in the chain.

14.Adjust the upper limit switch (See ADJUSTING UPPER LIMIT, page 8).
