Question 642 Deck General
70% to passWhat is the maximum weight the 30 ton capacity pedestal cranes shown in illustration D051DG can lift when married together in twin with the other pair of cranes at the opposite end of the hatch?
A
60 tons
B
120 tons
C
30 tons
D
90 tons
AI Explanation
The correct answer is B) 120 tons. When two 30-ton capacity pedestal cranes are married together in twin configuration at opposite ends of a hatch, their combined lifting capacity is 120 tons. This is because the cranes are able to work together to lift the load, effectively doubling the individual capacity of 30 tons per crane to a total of 120 tons. The other answer choices are incorrect because: C) 30 tons is the individual capacity of a single crane, not the combined capacity of two cranes; A) 60 tons is less than the true combined capacity; and D) 90 tons is an arbitrary number not supported by the information provided.
