HOIST CHECKS (AIR SUPPLY ON)

The pendant buttons, levers or cords should be smooth to operate and return to neutral when released (hoist stops and does not
run

▪
The hoist is run up and down on a regular basis. Where hoists are hanging in a dry and protected area they should be run weekly,
where the hoist is outside and not protected it should be checked, lubricated and run daily.
▪
The emergency stop button / valve operates immediately.
▪
Upper and lower limit switches / levers work satisfactorily.
▪
Load chains run smoothly over the pocket wheel.
▪
The load chain should be examined periodically for cracks, gouges and wear.
▪
Chain collectors should be checked for security and chain capacity.
▪
Check chain runs in and out of the chain collector smoothly.
▪
For hoists with a long drop of chain or a large chain collector a separate suspension point may be required (see section 1.8).
▪
Cord control hoists should have the toggles marked for raise and lower.
▪
On cord controls check the spool valve returns to neutral and the hoist stops when the cord is released.(hoist stops and does not
run
on).
▪
Check the silencer is not partially blocked by comparing the running speed without load against the speed in the manual.
