LABELS & PLACARDS
GENERAL INFORMATION
The Bridge Trolley (BT) is used to remove large batteries from electric industrial trucks.
The bridge trolley is maneuvered manually along a designated travel path on casters by a person at the rear of the unit by pushing/ pulling on the handle of the unit. It is directed along this path by a guide track mounted permanently to the floor. The battery compartments are raised and lowered independently using a manual hand pump located at the rear of the unit with a manual valve to switch operation between compartments. The batteries are removed from the truck by the operator physically grasping the battery and pushing or pulling the batteries on and off of the unit.

INSTALLATION
The following describes the basic installation procedures for the bridge trolley system.
Once the trolley has been removed from the shipping pallet, some minor assembly may be required.
Note: If the unit has been shipped without the bridge attached, DO NOT remove the bands going across the unit in place of the bridge until the bridge has been fully installed.
Bridge Trolley
- Engage the floor locks to prevent the trolley from moving.
- Position the bridge as shown in Figure 1. Note: If unit is shipped with the bridge installed, steps 2 & 3 will be skipped.
- Install and tighten the bridge hardware. Carefully cut and remove banding.
- Determine which side of the trolley is to be the track side.
- Install the guidance arms on the track side of the unit as shown in Figures 2 & 3.
- Adjust the height of the guidance arms as necessary to ensure full engagement of the guide rollers with the entire length of track without the guidance arm bracket contacting the top edge of the track.
- Check the hydraulic pump oil level. Oil level should be 1" from the top of the reservoir. If low, fill with Chevron hydraulic oil AW ISO 32 or equivalent ISO 32 grade hydraulic oil with anti-wear additives and foam suppressant. Pump capacity is approximately 0.5 Gal (1.9 L). Note: Oil level must be checked with both roller compartments FULLY lowered. See Figure 4.

Guide Track
Note: Reference system layout drawing if available. If no drawing is available, proceed as follows.
- Single Change Out - Determine which end of the system will be the truck change out end. The opposite end will be the starting point for installing the track. 48" (1219 mm) over-travel will be required at this end to allow complete access of both battery compartments to the endmost battery stand compartment. Dual Change Out - If trucks are to be serviced at both ends of the system, it is recommended that the overall truck length, battery removal side and position all be verified and then proper over-travel past the truck compartment be added to obtain track location (typically 48"/1219 mm).
- Measure and mark 2 7/8" (73 mm) from the front angle of the battery stands at each end of the system. See Figure 5.
- Using a chalk line, "snap" a line connecting the marks made in the previous step. This line will serve as an alignment guide for the location of the guide track. Note: Be sure to start the chalk line past the end of the stand allowing for over-travel of the trolley per step 1 and that the line is at least as long as the total length of track being installed.
- Position the first piece of guide track ensuring it is aligned with the chalk line and the proper over-travel is accounted for. Place all track sections end to end to verify correct track length and location prior to anchoring.
- Anchor the track section at each end and once in the center using the supplied 1/2" x 4" wedge bolts anchors. Anchor the entire section at each remaining hole.
- Position the next section, clamping it to the previous section installed. Anchor the hole closest to the joint. Verify alignment with the chalk line and continue anchoring per step 5.
- Continue installing each remaining sections per steps 5 & 6 ensuring the track is aligned with the chalk line.
- Position the end stops flush with the ends of the track and 6" (152 mm) from the face of the track. The rubber bumpers should face toward the trolley. See Figure 6.
- Anchor each end stop with (3) 1/2" x 4" wedge bolt anchors.

OPERATING INSTRUCTIONS
The following instructions will guide you through the basic steps necessary to operate and change batteries with a BT16-2.
Operators must be equipped with all necessary personal safety equipment and be properly trained in the handling of lead-acid lift truck batteries.
1. If not already in place, position the industrial truck (pallet or lift truck) which requires a battery change in the appropriate staging area.
2. Disconnect the battery leads and remove any battery restraints.
3. Move the bridge trolley into position such that an empty roller compartment of the unit is aligned with the battery compartment of the industrial truck and engage both floor locks.
4. Verify the Z-bar stop is open and the battery stop of the desired roller compartment is in the vertical position. Note: All other battery stops not in use must be left in their down or closed position.
5. To operate the near compartment, pull the selector valve handle all the way out. To operate the far compartment, push the selector valve handle all the way in.
6. Adjust the vertical height of the desired roller compartment of the bridge trolley to the battery compartment of the industrial truck. To lift the compartment, pump the handle up and down. To lower the compartment, turn the release handle of the hand pump counterclockwise to begin lowering and turn the handle clockwise to stop.
7. Carefully pull the lift truck battery into the bridge trolley battery compartment and return the battery stop to the closed position.
8. Release the floor locks and move the bridge trolley to align the empty roller compartment with a battery rack compartment containing a charged battery. Reengage both floor locks and raise the battery stop of the compartment to accept the charged battery. Note: The Z-bar stop should still be in the open position from removing the lift truck battery.
9. Adjust the vertical height of the desired roller compartment of the bridge trolley to the battery compartment of the battery rack.
10. Carefully pull the lift truck battery into the bridge trolley battery compartment and return the battery stop to the closed position.
11. Release the floor locks and move the bridge trolley to align the charged battery with the battery compartment of the lift truck. Reengage both floor locks and adjust the bridge trolley compartment height as necessary.
12. Raise the battery stop of the compartment to transfer the charged battery to the lift truck and rotate the Z-bar to the open position.
13. Push the battery into the lift truck compartment and reconnect the battery leads and restraints disconnected in step 2.
14. Return the discharged battery to the battery rack using the methods described above. The battery may now be connected to the charger as required.
15. Move the bridge trolley to the appropriate staging area when not in use and engage the floor locks to prevent unintentional movement.
As with all material handling equipment, the transfer carriage should be inspected prior to each use for any visual damage. It should also undergo a routine inspection by trained maintenance personnel to verify and maintain the load capacity of the unit.
