OPERATION:
Remove any load, release the operating controls, and detach the power cord before performing any inspection,
maintenance, or cleaning procedures. Frequent Inspection
TO PREVENT SERIOUS INJUREVENT SERIOUS INJUREVENT SERIOUS INJURY FROM TOOL FAILURE:
Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before
further use.
Perform the procedures in this section BEFORE INITIAL USE and AT LEAST MONTHLMONTHLMONTHLY.
Inspection is needed more often for heavily used hoists.
INSPECTION, TESTING, AND MAINTENANCE
FREQUENT INSPECTION
1. Check operating mechanisms for proper operation, proper adjustment, and unusual sounds such as,
but not limited to, binding noise of the wire rope and bearing squeal.
2. Check hoist upper limit device without a load on the hook at the beginning of each shift. Exercise care.
Run the load block into its limit device at slow speed.
3. Frequent Braking System Inspection
a. The braking system must automatically stop and hold up to the rated load if the operating controls are
released and in the event of complete power failure.
b. Braking systems must limit the speed of load during lowering, with or without power, to prevent
uncontrolled or rapid lowering.
4. Frequent Hook Inspection check hooks for the following problems:
a. distortion, such as bending, twisting, or increased throat opening;
b. wear;
c. cracks, nicks, or gouges;
d. latch engagement (if equipped);
e. damaged or malfunctioning latch (if equipped);
f. hook attachment and securing means.
5. Frequent Hoist Rope Inspection all ropes should be visually inspected by the operator or other
designated person at the start of each shift. These visual observations should be concerned with
discovering gross damage, such as listed below, which may be an immediate hazard:
a. distortion of the rope such as kinking, crushing, upstanding, birdcaging, main strand displacement,
or core protrusion;
b. general corrosion;
c. broken or cut strands;
d. number, distribution, and type of visible broken wires:
1) in running ropes, 12 randomly distributed broken wires in one lay or four broken wires in one strand
in one lay;
2) one outer wire broken at the contact point with the core of the rope which has worked its way out of
the rope structure and protrudes or loops out from the rope structure.
If such damage is discovered, either remove the rope from service or arrange for a qualified technician
to give it a periodic (thorough) inspection.
6. Check wire rope reeving.
