Daily Inspection
Daily inspections should be performed at the beginning of
each shift or before initial use of the crane each shift by the
operator or appointed person.

Check for any loose or missing parts.
Check end stops. End stops prevent the trolley from
running off the beam.
Know the location of disconnect switch that will cut the
power off only to the hoist or crane.
Be sure
it is readily accessible and not blocked.
Check upper hoist limit switch by slowly raising the block to
trip the switch.
Lower the hoist block to activate the lower limit switch if the
hoist is so equipped, leaving at least one turn of rope on the
take-up drum.

• Make sure all control buttons are labeled to indicate their
function. Operate each button to make sure it functions
properly, releases immediately, and does not stick.

Make sure wire rope is properly seated in its drum and
sheave grooves without any slack or overlapping.
Operate the crane or hoist several feet in each direction that
it travels. Listen for any unusual noises. Look for any jerky
movements.
When moving an A frame hoist, take care to ensure that the
wheels on each side stay on the track.

• Check all hooks.
• Hooks should not be cracked, stretched, bent, or twisted.
• Each hook must have a safety latch that automatically
closes the throat of the hook.
• If the latch is bent, spring is broken, or is otherwise
damaged the latch must be repaired before use.
• Hooks should rotate freely in block assembly without any
“grinding” felt or heard.
7
GENUINE SAFETY CONSULTANTS
• Check the block assembly for structural damage or cracks
in any components.
• Sheaves should rotate freely without any grinding felt or
heard coming from the bearings.
• The sheave guard must be unbroken and intact.
• No part of the sheave guard should be in contact with the
wire rope or sheave.

•
Check the wire rope by lowering the block to the lowest
level and looking for the following conditions. If any of
these conditions are observed, they should be reported
immediately.
• Reduced diameter of the rope. This may indicate the
rope has been stretched, has lost its inner core support,
or has worn outside wires.
• Any number of broken strands of wires.
• Kinked, crushed, cut, or “bird caged” wiring, or wiring
with heat damage.

GENUINE SAFETY CONSULTANTS
• Inspect the wire rope to make sure it is lubricated and
that none of the following conditions exist:
1. No kinks
2. No broken or cut strands
3. No bird caging
4. No corrosion
5. No core protrusion
6. No crushed sections of rope

•
Check load chain for damage, wear at contact points,
cracks, or distorted (bent, twisted, or stretched) links.
•
Inspect all mechanical coupling links to insure linking pins
are secure and in good condition.
•
Report unsafe conditions immediately.
•
Check the condition and capacity of nylon or synthetic
web slings. Capacity ratings must be legible on the
manufacturer’s label. The capacity of the sling being
used must be adequate for the load and attachment
method. Replace slings immediately if excessive wear
occurs.

OPERATIONAL SAFETY
• Do not overload the crane or hoist. Make sure the
combined weight of the lifter and load does not exceed the
rated load capacity of the crane or hoist.
• Refuse to make lift if you are unsure of any issues.
Do not proceed until all issues are resolved.
12
GENUINE SAFETY CONSULTANTS
• Take instructions only from the person designated to give
signals.
• Do not ride or allow other people to do so.
13
GENUINE SAFETY CONSULTANTS
• To pick up a load, move the crane
and hoist/hook directly above the
load to eliminate the possibility of
side loading and minimize load
swing.
14
GENUINE SAFETY CONSULTANTS
• Before lifting, ensure that everyone is clear of any pinch or
crush zones.
• When starting to lift the load, only lift it a few inches off the
ground to verify hoist brake is functioning properly before
continuing with the lift.
15
GENUINE SAFETY CONSULTANTS
• Make sure the rigging is in good
condition and that safe rigging
practices are applied.
• Ensure rigging is appropriate for
the load size, shape and
weight.
16
GENUINE SAFETY CONSULTANTS
• Always maintain a clear
view of the crane path
so you can observe any
obstacles or personnel
in your path.
17
GENUINE SAFETY CONSULTANTS
• Use one continuous
motion when traveling.
• Try not to start/stop
(plug) as this will result in
load swing.
18
GENUINE SAFETY CONSULTANTS
• Do not lift loads over people.
• Stay out from under the load and
make sure other people remain at a
distance.
• Do not become distracted while
traveling.
• If you need to speak with someone,
cease operation of the crane.
19
GENUINE SAFETY CONSULTANTS
• Never leave a suspended
load unattended.
• If you must leave the area,
lower the load to the
ground before doing so.
20
GENUINE SAFETY CONSULTANTS
• Stay clear while moving a load.
• Do not allow the load to swing.
• Use a rod to push the load or a tag line
to pull the load.
• Exercise particular caution with sheet
lifters.
• Be sure to keep the load level.
• Tilting the lifter could cause the load to
slide off the lifter.
21
GENUINE SAFETY CONSULTANTS
• When the crane is not in use, always raise the crane hook
above head level.
