is needed more often for heavily used hoists.

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.

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.

Frequent Braking System Inspection

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

Braking systems must limit the speed of load

during

lowering, with or without power, to

prevent

uncontrolled or rapid lowering.

Frequent Hook Inspection

Check hooks for the following problems:

distortion, such as bending, twisting,

or increased throat opening;

wear;

cracks, nicks, or gouges;

latch engagement (if equipped);

damaged or malfunctioning latch (if equipped);

hook attachment and securing means.

Frequent Hoist

Rope Inspection

All ropes should be visually inspected by the

operator

or other designated person at the start

each

shift.

These visual observations should be concerned with

discovering gross damage, such as listed

below,

which may be an immediate hazard:

distortion of the rope such as kinking,

crushing, unstranding, birdcaging,

main

strand

displacement, or core protrusion;

general corrosion;

broken or cut strands;

number, distribution, and type

of visible broken wires:

in running ropes,

12 randomly distributed broken wires in one lay

or four broken wires in one strand in one

lay;

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.

Check wire rope reeving.
