On 3rd point hoisting, the load will increase in speed for light loads and start to move with heavy loads.

On 3rd point hoisting, the load will increase in speed for light loads and start to move with heavy loads.

• A. True
• B. False
• C. Not sure
• D. N/A

Answer: (A)

The key idea is how load weight affects starting acceleration. A hoist delivering a fixed amount of torque or power can accelerate lighter loads much more quickly because there’s less inertia to overcome. With a light load, the rope speed can rise rapidly as the motor power is converted into motion. A heavier load, on the other hand, resists that acceleration due to greater inertia and friction; it takes longer for the motor to overcome static resistance, so the load may start moving slowly or require more time before movement begins. Once moving, the load tends toward the hoist’s rated speed, but heavier loads generally reach that speed more slowly than lighter loads. So the statement reflects how inertia affects starting and acceleration: lighter loads increase speed faster, heavier loads start moving more slowly.
