Question #728
Unless the manufacturer specifies otherwise, what is the permissible increase in hook throat opening?
O ile wytwórca nie określi inaczej dopuszczalne rozwarcie gardzieli haka wynosi:
a
2%
2%
b
5%
5%
Correct answer
c
10%
10%
d
15%
15%
Why?
The hook throat opening (rozwarcie gardzieli haka) may increase by no more than 5% of its original dimension, unless the manufacturer specifies otherwise. For example, an original opening of 100 mm allows an increase of 5 mm. The 10% limit concerns material wear at the throat (wytarcie gardzieli haka), not an increase in its opening.
