Which load-balancing device is used in tandem lifts to distribute the load?

• A. Beam clamps
• B. Periodic inspection
• C. Synthetic ropes
• D. Equalizer beam

Answer: (D)

Distributing the load evenly among multiple lifting points in a tandem lift is essential, and the device that accomplishes this is the equalizer beam. A rigid equalizer beam ties the multiple lift legs together so they share the load rather than one leg carrying most of it. It is rigged from the crane hook or lifting point, with slings or legs attached to its ends. As the lift proceeds, the beam helps keep the load level by allowing the individual legs to adjust and balance each other, preventing overloading any single line and reducing sway or binding. This is why the equalizer beam is the best answer: it directly provides the mechanism to balance forces across all lift legs and maintain stability during the lift. Beam clamps are used for gripping or attaching beams in other contexts, periodic inspection is a maintenance activity, and synthetic ropes are materials used for rigging rather than a device for distributing load in a tandem lift.
