10.0 Structure Load Requirements
The structure to which the Ladder Climb System is attached must be capable of
withstanding the total loads imposed by the system.
9.1 Static Loading:
The static loads imposed on the system include the weight
of the top bracket, weight of the length of cable used with the system and a
Safety Factor. The following is an example of static loads imposed on the
system for a 50 ft (15.24 m) system:
Top Bracket Weight =
24 lbs (10.9 kg)
50 ft. (15.24 m) of 3/8” (9.5 mm) Galvanized Cable Weight =
13.25 lbs (6.01 kg)
Total Static Loading:
(24 lbs + 13.25 lbs) x 1.2 (Safety Factor) = 47.3 lbs
9.2 Dynamic Loading:
The following are the Dynamic Loads imposed onto the
Ladder Climb System per user:
One User =
2,700 lbs (12 kN)
Two Users =
3,320 lbs (14.76 kN)
Three Users =
3,940 lbs (17.51 kN)
Four Users =
4,560 lbs (20.27 kN)
9.3 Total Loading:
The total load must account for the Static and Dynamic
Loading indicated above for the total length of the sytem. The following is
an example of the Total Loading imposed onto the structure given that the
example system is 50 ft (15.24 m) in length:
Static Loading for a 50 ft. (15.24 m) system =
47.3 lbs
Dynamic Load for Two Users =
3,320 lbs
Total Loading = 47.3 lbs + 3,320 lbs = 3,367.3 lbs
Total Loading of the system onto the attachment structure can be reduced by limiting
the number of user’s on the system.
Bottom Bracket Assembly:
The bottom bracket assembly connection point
must be capable of supporting the system pretension load of
350 lbs (1.6 kN)
in the direction of loading. The required bracket load may be assumed to be
distributed evenly between the number of rung attachments for calculation
purposes.
