Lifting
Use enough parts of line for all lifts and check all lines,
slings, and chains for correct attachment
. To obtain
maximum lifting capacities, the hook block must be set up
with enough parts of line. Too few parts of line can result in
failure of the hoist rope or hoist.
No less than three wraps
of wire rope
should remain on the hoist drum.
No less than
eight wraps of synthetic rope
should remain on the hoist
drum. When slings, ties, hooks, etc., are used, make certain
they are correctly positioned and secured before raising or
lowering the loads.
Be sure the rigging is adequate before lifting. Use tag lines
when possible to position and restrain loads. Personnel
using tag lines should be on the ground.
Be sure good rigging practices are being used. Refuse to
use any poorly maintained or damaged equipment. Never
wrap the hoist cable around a load.
If using a clam bucket, do not exceed 80% of the crane’s
capacity.
Make certain the boom tip is centered directly over the load
before lifting.
Ensure that all slings, ties, and hooks are correctly placed
and secured before raising or lowering the load.
Be sure the load is well secured and attached to the hook
with rigging of proper size and in good condition.
Check the hoist brake by raising the load a few inches,
stopping the hoist and holding the load. Be sure the hoist
brake is working correctly before continuing the lift.
When lowering a load always slow down the load’s descent
before stopping the hoist. Do not attempt to change speeds
on multiple-speed hoists while the hoist is in motion.
Watch the path of the boom and load when swinging. Avoid
lowering or swinging the boom and load into ground
personnel, equipment, or other objects.
Lift one load at a time
. Do not lift two or more separately
rigged loads at one time, even if the loads are within the
crane’s rated capacity.
Never leave the crane with a load suspended. Should it
become necessary to leave the crane, lower the load to the
ground and stop the engine before leaving the operator’s
station.
Remember, all rigging equipment must be considered as
part of the load. Lifting capacities vary with working areas. If
applicable, permissible working areas are listed in the
Load
Chart
. When swinging from one working area to another,
ensure
Load Chart
capacities are not exceeded. Know your
crane!
Stop the hook block from swinging when unhooking a load.
Swinging rapidly can cause the load to swing out and
increase the load radius. Swing the load slowly. Swing with
caution and keep the load lines vertical.
Look before swinging your crane. Even though the original
setup may have been checked, situations do change.
Never swing or lower the boom into the carrier cab (if
applicable).
Never push or pull loads with the crane’s boom; never drag a
load.
Do not subject crane to side loading. A side load can tip the
crane or cause it to fail structurally.
If the boom should contact an object, stop immediately and
inspect the boom. Remove the crane from service if the
boom is damaged.
When lifting a load the boom may deflect causing the load
radius to increase—this condition is made worse when the
boom is extended. Ensure weight of load is within crane’s
capacity on
Load Chart
.
Avoid sudden starts and stops when moving the load. The
inertia and an increased load radius could tip the crane over
or cause it to fail structurally.
Use tag lines (as appropriate) for positioning and restraining
loads. Check the load slings before lifting.
