The purpose of this procedure is to provide instructions for the ~

operation of the polar crane in a safe and proper way.

2.0 DESCRIPTION

The polar crane is a floor operated double trolley type crane located in the Reactor Building. The crane is used for fueling, maintenance lifts, and any ccher loads a crane might be needed for.

The main trolley has two hooks; the main hook with a name plate

.ating of 185 tons (certified rated at 200 tons) and an auxiliary hook rated at 25 tons. The main and auxiliary hooks are variable speed, with maximum speeds of four (4) FPM and 20 FPM, respectively.

The trolley and bridge traverse speeds are variable with a maximum speed of 40 FPM and 75 FPM, respectively. All operations are con-

, trolled from a 13 button pendant control station. (See Figurc f1)

. Vl/06/76 5.2 During the period when the reactor vessel head is removed and irradiated fuel is in the Reactor Building and fuel is not being moved, the Reac'cor Building polar crane hoists shall be operated over the fucl transfer canal only where necessary and in accordance .

with approved operating procedures. (TS 3.12.2) 5,. 3 During the period when the reactor coolant system is pressurized above 300 psig, and is above 2000F., and fuel is in the core, the Reactor Building polar crane hoists shall not be operated over the steam generator compartments. (TS 3.12.3) 5.4 Whenever taking slack out of the hoist cables, do not exceed an approximate hoist speed of six (6) FPM.

5.5 Whenever load is within~one (1) foot of the floor or other resting place, do not exceed an approximate hoist speed of two (2) FPM.

'5. 6 Whenever load is within five (5) feet of a wall or other obstruction, do not exceed a bridge or trolley speed of approximately two (2) FPM.

5.7 All objects on the polar crane shall be tied down to prevent their falling into the transfer canal.

5.8 The crane shall not be loaded beyond its nameplate rated load.

5.10.5 Personnel shall stand clear of suspended loads.

'5.10.6 The operator shall test the brakes each time a load approaching the rated load is handled by raising the load a few inches and applying the brakes.

5.10.7 The load shall not be lowered below ther point where less than two (2) full wraps of rope remain on the hoisting drum.

5.10.8 An operator shall be at the controls while a load is suspended.

5.11 Insure proper hand signals are used. (See Hand Signal Chart, Attachment #1) 5.12 Observe all crane safety preca'utions as per Met-Ed Safety Manual, when operating crane. -

5.13 Conduct of Operators 5.13.1 The operator shall not engage in any practice which will diver +

b. Push "up" button and observe hook moves up. Daily verify its up limit is functional.

dI.1.5 Bridge and Main Trolley Checks .

a. Enstre bridge and main trolley run in right direction (Direc-when forward and reverse buttons are actuated.

tions will be defined and marked on bridge and trolley.)

b. Daily run Bridge and Trolley to both limits of travel and verify that limit switches are functional.

7.1.6 Pendant Traverse Check Ensure pendant runs in right direction when forward and reverse buttons are actuated. .

7.2 Normal Operation 7.2.1 Select proper hook.

7.2.2 Observe Section 5.0, " Limits and Precautions."

7.2.3 Ensure checks in Sections 6.1 and 7.1 have been run prior to lifting any loads.

7.3 Shutdown land 7.3.1 Before leaving this crane unattended, the operator shall .
