4.6 Rope reeving
4.6.1 Hoisting rope guidance and reeving
a) Preparation
1) Choose a correct rope reeving in accordance with section 2.4.3 in Chapter 2.
2) The boom is placed straight ahead of the crane.
3) An assistant is present to guide the hoisting rope.
b) Assembly procedure
1) Place required hook block under the pulley head of boom.
2) On the hook block, remove the retaining springs and pull out rope guard tubes.
3) Start the crane engine.
4) Lay the hoisting rope over the upper rope pulley and reeve it between the pulley head
and the hook block.
5) Reinsert the rope guard tubes and then secure them with retaining springs.
WARNING
When the assistant guides the hoisting rope to the pulley head, the crane operator must
operate the winch. This procedure must be done in such a manner that the rope does
not slacken up on the winding drum.
DANGER
(1) Complete the assembly operation on a safe area! If it is unavoidable that the rope
must be hand-guided over the boom to the pulley head, proceed with great caution
when walking on the boom.
(2) There is a great danger of causing a serious accident if the crane function is not
operated properly and the person guiding the rope slips on the boom.
(3) Rope reeving for main boom and tip boom:
-
110USt (100t) load hook, 5 rope pulleys, corresponding rope reevings of 10, 9, 8,
7, 6.
-
55USt (50t) load hook, 3 rope pulleys, corresponding rope reevings of 6, 5, 4.
- 33USt (30t) load hook, 3 rope pulleys, corresponding rope reevings of 4, 3, 2.
-
8.8USt (8t) load hook, without rope pulley, 1 rope reeving.
From Figure 4-50 to Figure 4-52, the methods for rope reeving are shown when different
rope reeving is available. During operation, select proper load hook according to actual
lifting capacity, and reeve in hoisting rope in accordance with reeving plan.
When hoisting rope is guided over the deflection pulley on the main boom head to hook
block, ensure that the deviation angle of rope between these two pulleys is the minimum
angle. In other words, the guidance of hoisting rope from deflection pulley to hook block
must be complied with the requirements in the figure 4-53.
