Question #221

Using the load capacity chart and drawing shown, determine the maximum safe lifting height for the load picked up from direction B:

W oparciu o przedstawiony diagram udźwigu oraz rysunek określ maksymalną bezpieczną wysokość podnoszenia, ładunku pobranego z kierunku B:

Using the load capacity chart and drawing shown, determine the maximum safe lifting height for the load picked up from direction B:Open full-size illustration
a
5940 mm

5940 mm

b
7890 mm

7890 mm

c
3600 mm

3600 mm

Correct answer

d
4500 mm

4500 mm

Why?

When picking up from direction B, the dimension along the forks (widły) is 1400 mm, giving a load centre (środek ciężkości) of c = 1400/2 = 700 mm. There is no 700 mm column, so use the safer 800 mm column. At 3600 mm, the capacity (udźwig) is 1040 kg, enough for the 1000 kg load. At 4500 mm it is only 950 kg, so that height is too great.
