Question 1
Swinging loads can be controlled by which of the following controls?
Correct Answer:
Bridge or trolley controls
Explanation:
Swinging loads are managed by dampening the horizontal motion of the load. The way to do this is by using the crane’s horizontal controls—the bridge or the trolley—to move the load back toward the center or toward the desired position. Moving the hoist handles only changes how high or low the load is; that vertical motion doesn’t eliminate side-to-side swing and can even let the load oscillate more if used improperly. Safety devices like limit switches are for stopping travel at preset points and don’t actively damp swing. So, the best way to control swinging loads is with the bridge or trolley controls.
Question 2
Where should the hook block be positioned for shutdown?
Correct Answer:
Near the upper limit
Explanation:
When you shut down a crane, you want the hook block in a position that keeps the load and equipment clear and minimizes the chance of unwanted movement or interference. Parking the hook near the upper limit accomplishes this by keeping the block up high and away from the floor, obstacles, and work areas. It also places the hook out of the path of potential snag points and makes it less likely to swing into objects if there’s any residual movement when power is removed. In short, this upper-limit parking position provides the safest and most stable shutdown posture. Parking near the lower limit could put the hook close to the floor or gear, increasing risk of damage or snagging. Being halfway between limits doesn’t give the same clearance or predictability for a safe shutdown, and halfway between inner and outer limits isn’t a standard, safe parking position.
Question 3
What is the purpose of a restraining cord used on the pendant control box of an overhead crane?
Correct Answer:
Prevent strain on electric cord
Explanation:
A restraining cord on the pendant control box is there to protect the control’s wiring and connections by limiting how far the pendant can move. When the operator shifts, the cord could be tugged or the pendant could swing, and without a tether that movement can put strain on the electric cord, the plug, or the box itself. The restraining cord takes up that slack and prevents pulling, bending, or jerking that could cause damage or a failure in the control circuit. This helps keep control reliable and reduces the risk of electrical hazards from a damaged cord. Other options don’t describe the primary purpose. Keeping the box within reach is more about accessibility than protection, using the cord to control swinging loads isn’t how loads are managed, and keeping the box off the floor is about housekeeping or reducing damage from drops rather than preventing strain on the electrical cord.
Question 4
The hoist limit switch controls the upper limit of which crane component?
Correct Answer:
The load block
Explanation:
Hoist limit switches control the vertical travel of the lifting assembly. When the hook and its attached load (the load block) reach the preset highest position, the hoist limit switch stops power to the hoist motor to prevent over-raising. This protects the load rope, hook assembly, and surrounding structure from damage. Horizontal movement of the trolley or bridge uses different limit devices, so the upper limit by the hoist limit switch specifically applies to the load block.
Question 5
If the load does not balance after being raised off the floor, what should you do first?
Correct Answer:
Lower to the floor and adjust the rigging
Explanation:
When a load isn’t balanced after being raised, the priority is to restore balance by adjusting the rigging. A balanced load has its center of gravity directly under the crane hook, which keeps the load from tilting or swinging and reduces the risk of tipping or striking nearby people or structures. Lowering the load to the floor creates a stable base and lets you reposition or reconfigure the slings, shackles, or other rigging so the weight’s center of gravity lines up with the hook. Once balanced, lift again with better control. Carrying the load low without fixing the rigging won’t correct the balance, and trying to move it more slowly doesn’t address the root cause. Carrying the load high away from the crane increases leverage and swing, creating more danger.
