C. POSITIONING WHEEL GUIDE ASSEMBLIES (Reference Figures 19 and 20)
Items Needed:
Qty
Description
2 Mast Beams – Left & Right
2 Upper Wheel Guides – left & right (“L” & “R” on the assembly)
2 Wheel guide reinforcement bars, 3/4" x 1-1/2” x 11-1/4” L flat bar
2 Chain Adaptors
4 Cotter Pins
2 Chain Adaptor Pins (with cotter pin holes)
2 Master Links (chain size varies)
1. Place the upper wheel guide assemblies in the beam as shown in Figure 19a by
sliding them into the beam running space from below the guide angle near the
bottom of the mast beam.
NOTE: This step must be done first due to the limited access space once the
wheel guides are inside the guide beams & behind guide angles.
2. Attach the lifting chains to the chain adaptors and the chain adaptors to the upper
wheel guide locking cams using the high strength adaptor pins and cotter pins
provided as shown in Figure 19b.
3. Pull on the chain where it attaches to the wheel guide assembly. Slide the wheel
guide assembly down the beam until it is approximately seven (7) feet from the
bottom of the beam. The upper wheel guide blocks should then be positioned so
that they will align with the uppermost sets of holes in the carriage uprights once the
beam is raised into position.
NOTE: The safety cams will attempt to engage as you move them down the
beam. Rotate and hold them in a disengaged position while you slide them into
position.
4. Locate the ship-loose 3/4" x 1-1/2” x 11-1/4” flat bar and position between the
carriage upright and wheel guide as shown in Figure 20. Weld this bar to the wheel
guide as shown, then unbolt the wheel guide back-up bar from the wheel guide to
complete the welding on the inside of these parts. Grind this weld as needed to re-
bolt weldment to the wheel guide.
NOTE: Do not weld between the reinforcement bar and the carriage upright.
NOTE: These reinforcement bars are not optional !! The bars are absolutely
necessary to resist damage to the wheel guides if the locking cams should have to
be used in a free-fall arrest situation.
