Principle for determining the length of main boom anchoring rods:
When basic boom is 42'8" (13m) long, the length of anchoring rods must be 20'6" (6240mm).
There are three kinds of anchoring rods in accordance with main boom length: 9'10" (3m), 19'8"
(6m) and 29'6" (9m).
When main boom length increases by 9'10" (3m), anchoring rods length will also increase 9'10"
(3m), which includes a 11.8" (300mm) long anchoring rod and a 8'10" (2700mm) anchoring rod.
When main boom length increases by 19'8"
（
6m
）
, anchoring rods length will also increase 19'8"
(6m), which includes a 11.8" (300mm) long anchoring rod and a 18'8" (5700mm) anchoring rod.
The diameter of pin spindle for main boom anchoring rods is 1.969" (50mm).
Combination of main boom anchoring rods in “main boom” configuration is shown in the figure
5-43.
