3 1. GENERAL 1.1. Introduction This document is the operating and maintenance instruction manual for the Lift-Transport System manufactured by Dynamic Design Pharma, Mission Viejo, California for Customer General description of the Lift/Transport System The system is a transport device designed to safely and efficiently lifting and transporting NRC Canisters within the facility The Lift/Transport System is easily moved around by means of its four swivel casters, allowing maneuverability in all directions The Lift Transport System suspends the NRC Canister into position by means of a lifting arm that is adjustable in its elevation. A hand crank located on the side of the main column permits fine tuning of the NRC Canister elevation during docking For reference, the NRC Canister does not need to be rotated to dock onto a standard RTP port. The NRC canister features a forward flange that, by means of a bearing system and dynamic seal, is free to rotate in relation to the canister. As a result, the canister can be locked onto the RTP port without requiring to be rotated The NRC Lift/Transport System provides means of docking, undocking and transporting the NRC canister without requiring the operator to support the weight of the canister during the necessary operations.

12 6. OPERATIONAL INSTRUCTIONS NOTE The illustrations contained in this section depict the 460 NRC Canister but they are applicable to the 270 NRC Canister as well. The Lift/Transport interface features of the two canisters are identical Outriggers operation The outriggers provide stability to the Lift/Transport system during NRC Canister docking operations During transport, the outriggers are stowed away as shown in Figure 6 OUTRIGGER (STOWED) Figure 6 - Outriggers position during transport Page 12

13 During docking operations, the outriggers must be deployed as shown in Figure 7 OUTRIGGER (DEPLOYED) Figure 7 - Outriggers in the deployed position Page 13

14 The outriggers are attached to the lift base frame by means of the attachment pull pin shown in Figure The outriggers are locked in either the stowed position or the deployed position by the positioning pull pin shown in Figure 8. Make sure to keep the outrigger locked in their desired position at all times POSITIONING PULL PIN ATTACHMENT PULL PIN Figure 8 - Outriggers pull pin Page 14

15 Once the outriggers are moved to the deployed position, they must be locked to the ground by turning the lock down knob shown in Figure 9 until the lock down foot contacts and securely clamps the floor. LOCK DOWN KNOB LOCK DOWN FOOT Figure 9 - Outriggers lock down to the ground WARNING The outrigger must be solidly clamped against the floor to assure of their effectiveness. Failure to clamp the outriggers down against the floor could result in the rendering the system unstable with potential for injury and component damage Page 15

16 6.2. Outriggers attachment to the base frame Each outrigger is held in place by two (2) pull pins. One pull pin allows for rotation and separation of the outrigger from the base frame the other pull pin locks the outrigger into either the transport position or the deployed position To separate the outrigger from the base frames both pull pins must be removed, see Figure First remove the locking pull pin (the smaller one) Second remove the pivoting pull pin Reverse the above steps to install the outriggers onto the frame. LOCKING PULL PIN PIVOTING PULL PIN Figure 10 - Outriggers attachment to the base frame 6.3. Vertical adjustment of the Lift Arm position The Lift/Transport allows for vertical adjustment of the NRC Canister support Lift Arm position, see Figure A manual hand wheel is located on the side of the column. Actuation of this hand wheel causes the vertical movement of the Lift Arm. Page 16

17 Included into the hand wheel is an adapter for a socket wrench, to facilitate the connection to a drill motor NOTE If a cordless drill motor is used for driving the vertical position of the Lift, use it in the torque mode, typical RPM of approximately 400RPM. CAUTION Do not run the vertical drive system at speeds exceeding 3000RPM To raise the Lift Arm rotate the hand wheel CW To lower the Lift Arm rotate the hand wheel CCW DRIVE SOCKET ADAPTER HAND WHEEL LIFT ARM ASSEMBLY SYSTEM COLUMN Figure 11 - Hand wheel for vertical adjustment of the Lift Arm Page 17

18 6.4. Linear adjustment of the NRC support structure The Lift Arm assembly of the Lift/Transport System has built in components that allow for extension and retraction of the NRC Canister in the horizontal direction to aid the docking process, see Figure For retraction of the arm, rotate the knob CW For extension of the arm, rotate the knob CCW LIFT ARM ASSEMBLY NRC CANISTER SUPPORT STRUCTURE SYSTEM COLUMN Figure 12 - Linear translation of the NRC Canister support structure of the Lift Arm Page 18

19 6.5. Angular adjustment of NRC Canister support structure The Lift Arm of the Lift/Transport System has built in components to allow for angular adjustment of the NRC Canister during the docking process. See Figure Knobs are located on the top and underside of the NRC support structure, to help create parallelism between the Beta and the Alpha Port (see the docking process in this document for details) To change the angle of the NRC Canister, rotate the angular adjustment knob until the desired alignment is achieved.

20 6.6. NRC Canister Attachment to the Lift The Lift/Transport suspends the NRC Canister during transport and docking processes. To suspend the NRC Canister, the Lift features two hooks with safety gates that hook onto a lifting bar located on the top of the NRC Canister Figure 14 shows the Lift to NRC Canister interface NRC LIFTING BAR SWIVEL HOOK SAFETY GATE Figure 14 - NRC Canister attachment to the Lift Each hook is free to swing in the side to side direction. This movement permits the engagement of the hooks onto the canister. The same hooks are also rigid in the front to rear direction to allow reliable movement of the NRC Canister during the docking process Each hook also features a safety gate that, because of gravity, is free to swing down and lock. The safety gate locks the canister in place on the hook to prevent accidental separation of the NRC Canister from the Lift during transport Figure 15 shows the hook and gate system in schematic form Page 20

21 SUPPORT SUPPORT SUPPORT GATE GATE GATE HOOK HOOK HOOK NRC NRC NRC HOOK AND SAFETY GATE ENGAGED SAFETY GATE DISENGAGED HOOK AND SAFETY GATE DISENGAGED Figure 15 - Schematic of hook and safety gate system Follow these steps to connect the Lift to the NRC canister. Assume that the Canister is resting in its storage cradle on a horizontal surface Bring the Lift into rough alignment with the NRC Canister so that the hooks of the Lift arm are positioned just above the lifting bar located on the top of the canister Manually drive the lift arm down while raising the safety gate away from the hook. This will allow engaging the hook into the lift bar of the canister. NOTE If there is an angular misalignment between the lift arm and the NRC Canister, it will be difficult to simultaneous engage both hooks. Use the angular adjustment to bring the two close to each other so that the hooks can be freely engaged onto the NRC Canister lift bar Once both hooks are engaged, manually raise the lift arm to fully engage the hooks and slightly lift the NRC Canister off its resting cradle Once the hooks are fully and properly engaged, the safety gates will swing down and lock in place. Page 21

22 NOTE Inspect that both hooks are well engaged on the canister safety bar and that the safety gates are fully engaged into the locked position Lift the NRC Canister off its cradle approximately 2 inches and manually test the connection to the lift by shaking the suspended NRC side to side using its lifting handles. CAUTION Failure to properly connect the NRC Canister to the Lift could allow the canister to abruptly disengage from the Lift/Transport during transport. Such sudden separation will cause damage to the equipment. WARNING Failure to properly connect the NRC Canister to the Lift could allow the canister to abruptly disengage from the lift during transport. Such sudden separation could cause injury to the operator Page 22

23 6.7. NRC Canister transport The NRC canister can be safely transported within the manufacturing facility while suspended by the Lift/Transport system. Two ergonomically located handles permit easy maneuvering of the system As a safety measure, the Lift/Transport system should be in its lowest elevation during transport. Figure 16 below shows proper elevation of the NRC canister during transport. NRC CANISTER IN LOWEST POSITION Figure 16 - NRC Canister during transport Page 23

24 CAUTION It is recommended to lower the Lift/Transport system Lift Arm to its lowest elevation when the NRC Canister is being transported. CAUTION Care must be taken when moving the system within the facility. Abrupt changes in direction, bumps, and hitting stationary obstructions must be avoided. Page 24

25 6.8. Docking of the NRC canister to the RTP Port Docking the suspended NRC canister entails bringing the NRC canister beta flange into alignment with the alpha flange of the RTP port and performing the docking operation Please refer to the NRC canister instruction manual for details of the Alpha and Beta flange docking sequence Figure 17 shows the view that the operator has during the alignment of the Alpha and Beta flanges. ALPHA/BETA ALIGNMENT Figure 17 - Docking position - Operator view - NRC Canister to Alpha flange Page 25

26 Refer to Figure Move the linear adjustment of the NRC support structure to the retracted position, see previous section in this document Bring the NRC beta flange into proximity to the RTP port alpha flange Using the vertical and angular adjustments previously described in this document, visually bring the beta flange into alignment with the alpha flange PARALELLISM NRC IN VERTICAL ALIGNMENT TO RTP PORT Figure 18 - NRC Canister beta flange alignment to the alpha flange Page 26

27 Refer to Figure Visually check the alignment of the beta flange lugs in relation to the receptacles in the RTP port alpha flange. Rotate the beta flange of the NRC Canister as necessary RECEPTACLE IN THE ALPHA FLANGE LUG IN THE BETA FLANGE Figure 19 Beta lug alignment with the Alpha receptacle Using the linear adjustment of the NRC support structure bring the NRC Canister beta flange into contact with the Alpha flange Attempt to turn the NRC Canister handles. If the alignment is satisfactory, the lugs of the beta flange will engage the receptacle of the alpha flange with very little resistance. NOTE Proper alignment of the two components will result in a successful docking process. Misalignment between the two components will result in a docking process requiring excessive force to be performed. CAUTION Do not disconnect the Lift/Transport system from the NRC Canister unless the NRC Canister is clearly fully docked to the alpha flange Page 27

28 7. MAINTENANCE INSTRUCTIONS 7.1. System inspection use NOTE It is possible for components and hardware to loosen as a result of regular use.

32 Refer to Figure Check the tensioner mounting hardware Check the idler sprocket hardware Check the drive chain tension and adjust if necessary TENSIONER HARDWARE IDLER SPROCKET HARDWARE DRIVE CHAIN Figure 23 - Chain drive system inspection Page 32

33 7.2. Drive system description The following is description of the drive system and its principal components. See Figure Right angle gearbox that connects with rotation capability the external hand crank with the transmission assembly located below the bulkhead Drive shaft coupling that connects the gearbox to the drive shaft Drive shaft that transmits rotary motion from the gearbox to the drive sprocket of the transmission GEAR BOX HAND WHEEL DRIVE SHAFT COUPLING DRIVE SHAFT TRANSMISSION ASSEMBLY Figure 24 - Lift/Transport drive system Page 33

34 The following components are part of the transmission assembly located below the horizontal bulkhead. See Figure Drive sprocket that is driven by the drive shaft and transmits rotary motion to the driven sprocket Driven sprocket is rigidly mounted onto the vertical drive acme screw that moves the Lift Arm in the vertical direction The drive chain transmits motion between the drive sprocket and the driven sprocket The idler sprocket is freewheeling on a fixed shaft and provides means for applying tension to the drive chain TENSIONER DRIVE SPROCKET IDLER LOCKING NUT DRIVEN SPROCKET DRIVE CHAIN LOCKING NUT Figure 25 - Transmission Assembly CAUTION Do not over-tighten the two locking nuts shown in Figure 25 as it could cause damage to the bearings. The locking nuts must be tightened to the point of removing all vertical play and without applying locking torque. Page 34

35 The following components transmit the rotary motion from the hand crank to the Lift Arm assembly. See Figure The Acme screw turns, supported by a load bearing plastic washer The Acme nut is attached to the Lift Arm assembly The rotation of the Acme screw results in precise vertical positioning of the Lift Arm assembly LIFT ARM ASSEMBLY ACME NUT ACME SCREW Figure 26 - Acme nut and leadscrew detail Page 35

36 7.3. System lubrication The system is designed to be operated lubrication free except for the drive chain of the transmission assembly. NOTE Lubricate the drive chain at six (6) months intervals Remove the rear access cover to gain access to the transmission mechanism. See Figure 27 TRANSMISSION ASSEMBLY COVER MOUNTING SCREWS REAR ACCESS COVER Figure 27 - Rear access to the transmission assembly Apply a small amount of food grade grease to the chain and the teeth of the sprockets Actuate the mechanism to spread the grease over the surface of the components Wipe all excess grease from the transmission components. Page 36

37 7.4. Chain tensioning Tensioning of the drive chain is accomplished by tightening a tensioner swivel block located in transmission assembly Gain access to the internal components of the column by removing the rear access cover See Figure Locate the chain tensioner assembly See Figure Loosen the tensioner stud to allow the tensioner block to swing Adjust the tensioner stud until the desired tension is achieved NOTE A tightening torque is not given because it is not critical. The chain load is unidirectional because of gravity force applied by the Lift Arm. Apply just enough tension as to prevent slack side to side movement of the chain when pressed by a single finger CAUTION Do not over tighten the chain. Excessive tightening is not necessary and creates undesirable stress on the chain and bearings of the system Tighten M10 hex locknut while blocking the tensioner stud to prevent it from turning Test the chain tension by turning the hand wheel and watching for excessive slack in the chain when turning direction is reversed Page 37

38 7.5. Component inspection The ball bearing and the drive chain shown in Figure 28 must be inspected for potential corrosion at regular intervals. NOTE Conduct this inspection at three (3) months intervals Inspect the ball bearing for corrosion. Replace the ball bearing only if corrosion is visible and is clearly affecting functionality. Do not replace if the ball bearing is simply discolored and its functionality is unaffected Inspect the chain for corrosion. Use a clean rag and alcohol to remove residual grease from the chain. Replace the chain if corrosion is visible and is clearly affecting functionality. Do not replace the chain if the chain is simply discolored After the chain is inspected re-apply lubricant per section 7.3 BALL BEARING ACCESS PANEL DRIVE CHAIN ACCESS PANEL Figure 28 - Inspection Components Page 38

39 7.6. Removal of the lift arm assembly from the system Removal of the Lift Arm is necessary to service the cam followers or to rebuild the NRC Canister support structure. See Figure 29 NRC CANISTER SUPPORT ASSEMBLY CAM FOLLOWERS Figure 29 - Lift Arm Assembly Removal of the Lift Arm from the system requires disconnecting it from the Acme drive screw system and raising it off the guide rails located within the column assembly.
