Inspect carrier clamps (some models will contain a swaged on carrier lug in place of the •
carrier clamp- see Figure 17). Cable should extend above carrier clamp 1.0 inch (2.5 cm) to
2.0 inch (5.0 cm). Adjust cable if amount of cable extension is outside of described range.
Steel washer should be present between carrier clamp and shock absorber.
Look down the inside of the pipe and inspect the shock absorber for damage such as cracks or
•
splits. The bottom of the shock absorber should project out the bottom hole in the top bracket
pipe. Replace the shock absorber if defects are found.
Inspect the cap that fi ts on the top of the pipe. Check for cracks or damage to the cap. The
•
cap should fi t securely onto the pipe. Replace if defects are found.
Bottom Bracket:
;
Reference Figure 21.
Check for proper installation (see Section 3.6). •
Check for damage or corrosion. Look for cracks, bends or wear that could affect the strength •
and operation of the system. Replace parts if defects are found.
Check for loose or missing fasteners that secure bottom bracket to the structure. If fasteners
•
are loose, re-tighten to listed torque levels. Torque on 3/8 inch fasteners should be 20-25
ft-lbs. (27-34 N-m). Torque on ½ inch fasteners should be 40 -45 ft. –lbs. (54-61 N-m).
Retighten as necessary.
Inspect the tension rod assembly. Make certain saddle clips securely retain the cable. Check
•
torque on saddle clamps – 35 ft. lbs. (47 N-m). Replace or retighten if defects are found.
Cable Guides:
;
Reference Figure 18.
Check cable guides for damage. Look for wear or damage to black urethane. Cable guides •
should restrain the cable and prevent cable contact with the ladder/structure. Cable guides
should be placed approximately every 25 ft (8 m) or closer if required. Replace parts if defects
are found.
Check cable guide fasteners. The fasteners should the secure cable guide in position. Tighten
•
as necessary.
Cable and Cable Tension:
;
Reference Figure 21 and Figure 23.
Inspect the cable for corrosion, kinks, or damage that will affect strength and impede the •
cable sleeve from traveling on the cable. Look for worn or broken strands of wire. Inspect for
signs of abrasion against the ladder or structure. Replace the cable if defects are found.
Inspect the cable tension. For systems that utilize a compression spring (Figure 23), the
•
spring in the bottom bracket should be compressed to 5-1/2 inch (13.8 cm) length. For
systems that utilize a tension rod and tension indicator washer (Figure 21), the washer should
be indicated (center ridge sheared off) and the washer imbedded fully into hole of bottom
bracket. You should not be able to pull tension rod down by hand. Cable should be tight
enough to prevent contact with the ladder/structure. Re-tension the cable if necessary. For
bottom brackets that contain an indicating washer, a new washer (part no. 9504239) should
be installed if the cable is re-tensioned. Tighten the system until indicating washer ring is
sheared off. Do not over-tension the system.
Installation and Service Label:
;
Reference Section 8.
Inspect the installation and service label. The label should be securely attached and fully •
legible. The installation date and number of users allowed on the system should be clearly
marked on the label. Record the inspection date on the label after inspection is completed.
Ladder/Climbing Structure:
;
Inspect the ladder/climbing structure to which the Lad-Saf •
®
system is attached. Make sure
the structure is in good condition, secure, and safe to climb. If the condition of the structure is
questionable, consult instructions and/or personnel familiar with the structure prior to use.
