Question #270
Based on the load capacity chart and drawing shown, determine the maximum safe lifting height for the load picked up from direction A:
W oparciu o przedstawiony diagram udźwigu oraz rysunek określ maksymalną bezpieczną wysokość podnoszenia, ładunku pobranego z kierunku A:

5940 mm
5940 mm
Correct answer
b
7890 mm
7890 mm
c
3600 mm
3600 mm
d
4500 mm
4500 mm
Why?
When picking up from direction A, the dimension along the forks is 800 mm, so the load centre distance (odległość środka ciężkości ładunku) is c = 400 mm and the conservative choice is the 500 mm column. At 5940 mm, the rated capacity (udźwig) is 1100 kg, enough for the 1000 kg load. At the next listed height of 6390 mm, capacity drops to 900 kg, making 5940 mm the maximum safe height in the table. The 7890 mm height is available only for much lighter loads.
