r 2.11 2-Ton Manual Chain Hoist with Plain Trolley The 2-ton manual chain hoists with plain trolleys XCR-23A and XCR-23B 1
are located in the Auxiliary hailding on elevation 412' at column lines J to N and 7.7.
The hoists and trol;eys are shown on Figure 3 along with its safe load paths.
Hoists XCR-23A and XCR-23B are supplied by the American Chain and Cable Company, and are 2-ton capacity hand operated chain hoists on plain trolleys. The hoists have a 26 foot lift and a forged steel shank hook.I The hoists and trolleys are designed in accordance with l
~
CMAA Specification 70 for Class A and C indoor service and ANSI B30.2, Cnapter 2-2 to the extent to which they are applicable.
Hoists XCR-23A and XCR-23B are designated to service the Reacter Building Spray Protective Sump Isolation Valve Chambers XSM-4A and XSM-4B, and the Safety Injection Recirculation Sump Isolation Valve Protection Chambers XSM-5A and XSM-5B. Near hoist XCR-23B is a Motor Control Center XMC-1DAZY and an Air Handling Unit for Motor Control Center XAH-32-VL, both of which are necessary for the safe shutdown of the plant.
Procedures are being developed and design modifications studied to minimize the chances of an inadvertent load drop causing damage to the adjacent protective chambers and the motor control center and accompanying air handling unit.

2.12 8-Ton Manual Hand Chain Hoist with Geared Trolley The 8-ton manual chain hoist with geared trolley XCR-24 is located in 1
the Turbine Building on elevation 463' at column lines F and 4 to 5.
The hoist and trolley are shown on Figure 11 along with their safe load paths.
Hoist XCR-24 is supplied by the American Chain and Cable Compaty, and is an 8 ton capacity hand operated chain hoist with a geared t'rolley.
The hoist has a 20 foot lift and a forged steel shank hook.I The hoist and trolley are designed in accordance with CMAA Specification 70 for Class A and C indoor service and ANSI B30.2, Chapter 2-1 to the extent to which they are applicable.
Hoist XCR-24 is designated to service the Main Steam Stop Valves XVG-2809 A to D.
Since the Turbine building contains no equipment necessary for the plant's safe shutdown or decay heat removal, this hoist can be excluded from further study or concern.

m 2.27 1-1/2 Ton Hand Chain Hoist and Plain Trolley C
The 1-1/2 ton hand chain hoist and plain trolley XCR-48 is located on elevation 412' of the Turbine Building at column lines B.8 to D and 12 above the Instrument and Service Air Compressors. The hoist is she>a on Figure 9 along with the safe load path.
Hoist XCR-48 is supplied by the American Chain and Cable Company, and is a 1-1/2 ton capacity, manually operated, chain hoist on a plain trolley. The hoist has a 17 foot lift and a forged steel shank hook.I The hoist and trolley are designed in accordance with CMAA Specification 70 for Class A and C indoor service, and ANSI 30.2, Chapter 2-1 to the extent to which they apply.
Hoist and trolley XCR-48 service the Instrument and Service Air Compressor, XAC-3A and XAC-3B, uhich are not necessary for the plant's 1
safe shutdown or decay heat renoval. On this basis XCR-48 can be excluded from further study.
