C. POSITIONING WHEEL GUIDE ASSEMBLIES (Reference Figures 19 and 20)
Items Needed:
Qty
Description
4 Mast Beams – Left Front, Right Front, Left Back, Right Back
2 Left Hand Wheel Guides – Marked with “L” on the assembly
2 Right Hand Wheel Guides – Marked with “R” on the assembly
4 Chain Adpators
8 Cotter Pins
4 Chain Adaptor Pins (with cotter pin holes)
4 Master Links (chain size varies)
1. Attach the chain adaptors to the wheel guide locking cams using the high strength
adaptor pins and cotter pins provided as shown in Figure 19b.
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. Slide each Left and each Right wheel guide assembly inside its respective mast
beam from the bottom as shown in Figure 19a (with the locking cams facing
up), clamping each into place while setting the carriage.
NOTE: The safety cams will attempt to engage as you move them up the
beam. Rotate and hold them in a disengaged position while you slide them into
position.
3. Pull on the chain adaptor where it attaches to the wheel guide assembly. Slide the
wheel guide assembly down the beam until it is approximately four (4) feet from the
bottom of the beam. The upper wheel guide blocks should then be positioned so
that they will align with the sets of holes in the carriage uprights once the beam is
raised 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.
