19-2-4 Boom derricking and lowering
(0099-0016-3E)
(1) When you derrick and lower the boom, the working radius
increases as the angle of the boom decreases, increasing the risk
of tip over.
(2) Beware of overhoisting the hook
When the boom is lowered or extended, the hook is wound up,
possibly causing overhoisting and damage when the hook block
hits the boom top. Normally the overhoisting detector will act to
prevent this, but if the detector is inoperative and overhoisting
occurs, lower the hook to the proper position.
When a lifting load is overhoisted, the distance between the
load and the boom is reduced and the load can hit the boom and
damage it.
The size of the lifting load must also be taken into account.
19-2-5 Winch operation
(0099-0017-2E)
(1) Choose a hook and wire rope number of parts of line suitable
for the mass of the load from the lifting capacity chart.
(2) When lifting the load, pause briefly when it has just left the
ground to check for safety and then continue the operation.
