In the event that an inspection of the following components results in the need to replace hardware or
assemblies, see the individual service kits listed in the previous section of this service manual. Remove
lift from service until required repairs are complete.
Note: Joerns Healthcare recommends that nyloc nuts be replaced once removed.
Spreader Bar
1. The spreader bar assembly is attached to the boom using a security pin that is housed in a steel outer
sleeve. Remove the inner security pin by depressing the security tab on one end and pulling the pin
out in the opposite direction.
2. Examine the pin for signs of wear and for any damage that may have occurred to the security tab.
3. Be sure to support the spreader bar before removing the outer sleeve as this is the attachment point.
Pull the outer sleeve bushing from the boom pivot. Inspect the outer sleeve for wear.
4. With the outer sleeve removed examine the attachment point of the boom for wear. If the pivot hole is
out of round the boom and security pin assembly should be replaced.
5. With the spreader bar detached from the boom examine the attachment point for wear. This applies to
both scale and non-scale versions of the HPL700 patient lift.
6. Disassembling the kingpin or scale from the spreader bar is not recommended, and may result in
injury or death if tampered with.
7. Check the spreader bar sling hooks for wear or damage. Ensure that the hooks are not bent.
After performing all actions and checks in the previous section reassemble the spreader bar as follows:
Instructions apply to both the scale and non-scale versions.
1. Lubricate the main pivot components (security pin, outer sleeve, and boom pivot attachment holes)
with any light food grade spray lubricant. Ensure that the there is ample lubricant applied to the
contacting surfaces of the security pin and sleeve. Also apply lubricant to the boom pivot attachment
holes.
2. Align the spreader bar attachment point to the boom pivot attachment holes. Insert the outer sleeve of
the security pin through the boom attachment holes. Scale versions will have additional spacers that
will need to be assembled to each side of the scale housing before the outer sleeve can be inserted in
the boom attachment holes.
3. Insert the security pin through the outer sleeve ensuring that the security tab is visible on the opposite
side of the outer sleeve when it is assembled.
Note: It is critical that the spreader bar assembly is inspected after reassembly prior to returning the lift to
service.
