in accordance with inspection schedules prepared by the L
plants and shall consist of at least all items on Checklist 3.1-2, " Periodic Inspection of Overhead and Gantry Cranes."
r b
3.1.1.4 Cranes Not In Regular Use--Cranes which have been idle for a period of one month or more, but less than one year, shall receive the frequent inspection listed in 3.1.1.2 before use.
L 3.1.1.5 Inaccessible Cranes--Cranes that are inaccessible during the annual inspection period (i.e., a reactor building F
polar crane during an 18-month refueling cycle) shall h_
receive a periodic inspection in accordance with paragraph 3.1.1.3 before using.
3.1.2 Testing
,o.
3.1.2.1 Operational Tests--Before use, all new, reinstalled, altered,

PRECAUTION: Adjust the hoist device trip setting i
by traveling the empty hook in increasing speeds up to the maximum speed, Locate the actuating mechanism of the limit switch so that it will trip the device under all conditions in sufficient time to prevent
,q contact of the hook or load block with any part of 9
3d the trolley or crane.
3.1.2.2 Rated load test--Before initial use, all new,
~
extensively repaired, or altered cranes shall be 2

1.1 The operator shall not engage in any practice which will 3
divert attention while actually operating the crane.
."j 1.2 'When physically or otherwise unfit, an Operator shall not engage in the operation of the equipment.
1.3 The operator shall respond to signals from the person who is j
directing the lif t or an appointed signal person. When a d
signal person or a crane follower is not required as part of the crane operation, the operator is then responsible for the 7
lifts. However, the operator shall obey a stop signal at all
]
times, no matter who gives it.
1.4 Each operator shall be responsible for those operations under the operator's direct control. Whenever there is any doubt as to safety, the operator shall consult with the supervisor before handling the loads.
i.
1.5 If a warning device is furnished, it shall be activated each time before traveling and intermittently when approaching work persons.
,]
_J 1.6 Before leaving the crane unattended, the operator shall land any attached load, place controllers in the "off" position, and open the main-line device of the specific crane.
j 1.7 The operator shall not close the main-line disconnect device until certain that no worker is on or adjacent to the crane.
If there is a warning sign or lock on the device, it shall not i
be energized until the sign or lock is removed by the person who placed it thereon.
1.8 Before closing the main-line device, the operator shall see to it that all controllers are in the "off" position.
i 1.9 If power goes off during operation, the operator shall immediately a
place all controllers in the "off" position. Before reuse of the crane, operating motions shall be checked for proper
['
direction.
1.10 The operator. shall be familiar with the equipment and its proper care. If adjustments or repairs are necenary or any defects are known, the operator shall report the same promptly
_i to the appointed person who shall be responsible for the safe-operation and maintenance repairs of the crane. The operator shall also notify the next operator of any remaining uncorrected defects upon changing shifts.

determined that the stability of the crane is not t
thereby endangered and that various parts of the crane

use of a work platform attached to the crane hook is permitted. A four-point lifting bridle must be used and the crane hook must have a safety latch or other means to prevent accidental release of the bridle.
Each person in the work platform must wear a safety J
belt with the lanyard secured to the hook.

[
special operations may require additions to, or modifications L
of, the basic signals standardized herein. For all such cases, these special signals should be agreed upon and thoroughly understood by both the signal person and the operator and
.r i
should not be in conflict with the standard signals.
3.2 Hand Signals--Hand signals shall be posted conspicuously.
[
(See figure 1.)

Inspection (1) Test the hoist under load in hoisting and lowering directions and observe the operation l
of the chain and sprockets. The chain should J
feed smoothly into and away from the sprockets.
(2) If the chain binds, jumps, or is noisy, first
~
see that-it is clean and properly lubricated.
If trouble persists, inspect the chain and cating parts for wear, distortion, or other I
dcmage.
J (3) Exanine visually for gouges,. nicks, weld splatter, corrosion, and distorted links. Slacken the chain and move adjacent links to one side to inspect for wear at contact points. If wear is observed or if stretching is suspected, the chain should be measured as follows:

(6) When the chain is replaced, disassemble the hoist and inspect the mating parts for wear and replace if a
necessary.
a c.
Maintenance (1) Load chhin and hand chain should be kept clean and free from rust and from any coating deposit that will build up and change its dimensions or reduce flexibility.
a
