Can two lifting devices be used together to lift a heavier object than either one alone?

Yes, two lifting devices can be used together to lift a heavier object than either one can handle alone, provided that both devices are capable of supporting the combined weight and are properly synchronized. This requires careful planning and coordination to ensure the safety of the operation and the integrity of the lifting devices. The total weight capacity of the combined system should be greater than the weight of the object being lifted, and the devices must be designed to work in tandem without overloading or causing damage.
