(4) Operation Test
(A) Firmly push switch button to lower load chain until the limit spring
touches the limit switch. Power should be cut off automatically.
(B) Firmly push switch button to check the collection of load chain into
chain bucket.
(C) Check the emergency stop device function (if fitted):
While holding down either or button on the push button switch,
push the emergency stop button. Check that the hook stops when the
emergency stop button is pushed. Also, check the hoist does not move in
response to the push button switch. Finally, check that the emergency stop
device pops out when turned to the right and that operation can be resumed
thereafter. If the equipment fails to pass another above checks, check the
wiring and automatic locking function of the emergency stop device.
(D) Check load chain lubrication (It has been lubricated at our works, but the
lubricant may dry out during transportation). Any readily available lubricant
is recommended. It is further advisable to keep a small amount of lubricant in
chain bucket to allow chain in oil bath.
(E) Check chain position. Weld joints on links must face the same direction (Illus.
8), correct chain operation can only be achieved when all joints are vertically
in line.
CAUTION
The bottom hook on multi-fall hoist must never be rotated as shown below
(Illus. 9).
