How is a crane defined in construction?

In construction, a crane is specifically defined as power-operated equipment capable of hoisting, lowering, and horizontally moving a suspended load. This definition encompasses the fundamental operational capabilities of cranes, which are essential for lifting heavy materials and equipment in various construction scenarios.

The ability to hoist and lower loads denotes the vertical movement, while the capability to move loads horizontally is crucial in construction settings where positioning of materials and equipment is required. This comprehensive functionality distinguishes cranes from other types of lifting equipment, which might not have the same range of motion or power.

While other choices mention aspects like the ability to move horizontally and vertically or the general function of lifting and transporting, they do not fully capture the specific power-operated aspect or the precise operations of hoisting and lowering a suspended load, which are critical to the definition of a crane in construction.
