3 Question 25. Should a crane be set up next to an open trench or excavation? (Explain you answer.)Answer: No. The crane should not be set up close to a trench or an excavation as the weight of the crane causes added pressure to the nearby soil. This can cause the trench or excavation to collapse and result in the crane overturning.WRONG
4 Question 25. (continued) What general rule would apply to setting up next to an open trench / excavation?Answer: As a general rule, the distance of the crane from the edge of the excavation/ trench should be at least the same as the depth of the hole. In other words, one meter of depth equals one meter from the edge (1.1).RIGHT
