Wire rope

• Directly supp)orts the load

* Dual reeving provides a redundant load path • 5:1 individual rope safety factor

* 10:1 system safety factor

o Testing of the wire rope Breaking strength test from sample of the rope installed

• Testing of the wire rope end fittings - 200% Proof Test based on wire rope strength

Equalizer /Load Transfer System

"* Equalizes rope tension during normal operation "* Equalizer is s€ingle failure proof connecting the dual ropes "* Design basis is enhanced safety (10:1 Safety Factor) "• Absorbs energy during a broken rope event "* Energy is absorbed via a honeycomb crush pad "• Crush pad is contained in a double acting steel cylinder "* The piston cylinder was proof load tested at the maximum

load transfer value

Braking Systems

S1Holding -rake systems are redundant Primary brake located on high speed shaft

-- Emergency brake located on drum providing redundant drive train "* Holding brakes rated min. 165% torque where acting "* Control brake is dynamic provided via the freq. drive "* All brakes were individually tested at 125% of DRL * Any of thie brakes can stop the DRL load in less than 3"

inches

Structural Systems

"* Support the mnechanical & electrical systems

"* Structure provides support during & after the SSE

"• Structural systems are passive & not prone to wear

Trolley Frame

"• Indirectly supports the load "• Is passive and therefore is not subject to wear "* Is seismically designed to support the load during & after

OBE & SSE "* Is a welded steel plate structure "• Critical Components testing requirements include:

- Load Girt ..... CMTR, C of C, & Impact test

- Welds .......... MT or PT

Drum Catching Device

"* Structural members located V2" below drums "* Support the drum in the event of shaft or support failure "* Drum shell f'ailure is not a credible event "* Critical Con- ponents testing requirements include:

- Device..........CMTR, C of C, & Impact test - Welds ....... MT or PT

Electrical System

"• Provides control of the mechanical energy to move load "* Operator at all times has 2 means of stopping system "* Power is removed from crane on sensing of vibration on

the floor "• Removal of power places crane in safe condition

* Electrical system is not required to function during a seismic event

Flux Vector Variable Frequency Drive

"* Drive is the basis of the electrical system "* Drive controls the motor & primary brake "* Provides control braking via dynamic braking "° Drive provides the following features

- Torque proving at start

- Brake checking

- Load Float (Zero speed) .- Ability to precisely limit input drive torque

Hoist Upper Travel Limits

Redundant limits of differing designs "* Primary i:,; gýcar type control limit "* Final is the block actuated (paddle) power !ype limit "• Final limit removes power from motor "* Limits are NUREG-0554 alternate design

Over Speed Limits

"* Senses hoist over speed independent of the flux vector drive

"* Limit is electrically isolated from drive "° Limit provides control redundancy "• Actuation of limit sets both holding brakes stopping load

Over Weight Limit

0 Limit senses over capacity lifts setting brakes 0 Limit senses load hang-up * Limit protects crane from over stress • Limit actuation only permits hoist lowering

Wire Rope Protection Limits

"• Drum mnis-spioling limit protects wire rope from misspooling onto drum

"* Unbalanced load limit protects wire rope & crane from off center lifts

"* Actuation of either limit stops hoisting motion

Emergency Stop Buttons

"• Remove power from the crane Sets holding brakes

- Placing crane in a safe condition

"* Button located in the cab "* Toggle switch located on each radio control
