When traveling with a suspended load in a pick and carry operation, the load line should be:
Answer: As short as practical to minimize load pendulum effect
Keeping the load line as short as practical reduces the pendulum effect and improves load control during travel.
Which of the following is a key stability concern unique to pick and carry operations compared to stationary lifts?
Answer: Dynamic forces created by acceleration, deceleration, and turns
Dynamic forces from starting, stopping, and turning create additional stresses not present in stationary lifts, making them a unique pick and carry hazard.
When a pick and carry crane must travel on a slope, the load should generally be positioned:
Answer: On the uphill side of the crane
Positioning the load on the uphill side helps maintain stability by keeping the center of gravity within the tipping fulcrum.
Before beginning a pick and carry move, the operator must consult the load chart to verify capacity for:
Answer: Both the lift and travel configurations, including all radii during travel
Pick and carry charts specify capacity for travel conditions, which are different and usually lower than stationary lift capacities.
What is the primary reason travel speeds during pick and carry operations are kept very slow?
Answer: To minimize dynamic load factors that can exceed chart capacity
Slow speeds minimize dynamic forces that can multiply the effective load weight and cause tipping or structural failure.
During pick and carry travel, if the operator must make a turn, they should:
Answer: Make wide, gradual turns at the slowest safe speed
Wide, gradual turns at slow speed reduce centrifugal forces on the suspended load and maintain crane stability.
Which document governs the maximum allowable load for a rubber-tired crane performing pick and carry over the front?
Answer: The manufacturer's load chart specific to travel mode over front
The manufacturer's load chart for travel mode, specifying direction (front, side, rear) and travel conditions, is the authoritative document.
