Endcap shielding senarios:

•YE1-2 Gap senarios – (Ref. Boki C vs Surkov 6)• YE1 closed and YE2 opened 3.05m

•YE2-3 Gap senario – (Ref Boki E vs Surkov 2)• YE1 open 3.74m YE2 open 3.84m and YE3

opened 7.64m •YE3-4 Gap senario – (Variation of Surkov 3)• YE1 and YE2 closed YE3 open 0.1m YE4 opened

3.8m. • Note 1: YE3 and YE4 can be opened more if gap

remains at 3.7m as long as YE4 is not opened more then 6.7m• Note 2: Supporting outriggers with a 3.7m gap

and no or minimal bracing to YE3 allows for cherry picker access and maximum crane coverage

Steps of installationStep 1 - Drilling and taping of holes for shielding supportNote: This is done after the existing beam pipe is removed

Will add a view to show drilling

Step 2 - Install permanent mountsNote: leaving the shielding mounting hardware on YE2 requires a small modification to the spacer disk shielding

Will add a view to show permanent mounting features

Step 3 - Installation of the guidesThe guide post slides into base and is secured with a quick release pin. The guides should be installed for both the external and internal shielding assemblies

Weight is approximately 10 pounds (5 kg)

Rated side force is approximately 310 lbs(140kg)

Step 4 - Adjust pick point on lifting beamMatch the pitch of the shield to the pitch of the hall.

Pick point slides to adjust

Secures pick point to set position

Step 5 - Install and secure external half of shielding assemblyISO view of shielding before installation

Note will show ropes/tethers for additional guidance

Additional fixtation will be located here

Step 6 - Close the bottom doorsDoors must be closed before the second shielding assembly is installed

Will show a end view with doors closed

Step 7 - Install and secure IP side of the shielding assembly

Repeat steps 4-6

Will add a view showing the second half being installed

Removal Done in reverse order of assembly

Note: If additional lead is added after installation, it must be removed to establish the original center of gravity. The pick point of the lifting beam must be returned to its original position for that assembly before removing that assembly

Adapter is required for mounting the to the front of the YE3 disk

Will add view

T1 cables and flexible pipes will be pulled back to the external side of the YE4 inner disk The cables and flexible gas and water lines will be disconnected from the IP side of the YE4-outer so it can be moved with the YE4 wall. The cables and flexibles will be tied back on the external side so that they are not damaged when the shield is installed on the IP side?
