Operation - Pacific Hoists U-MEGA Series Operations Manual & Parts List

(d) Check the emergency stop device function :
While holding down either
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 any of the
above checks, check the wiring and automatic locking function of the emergency stop
device.
(e) Check load chain lubrication (It has been lubricated at our works, but the lubricant
may dry out during transportation). It is also advisable to keep a small amount of
lubricant in the chain bucket to keep the chain in an oil bath.
(f) Check chain position. Weld joints on links must face the same direction (Illust. 8).
Correct chain operation can only be achieved when all joints are vertically in line.
The bottom hook on multi-fall hoist must never be rotated as shown below. (Illust.
