What component of PARS is designed for both pulling and lifting operations?

The correct choice revolves around the versatility of the spreader in performing both pulling and lifting operations. A spreader is particularly effective in lifting and moving heavy loads by distributing the load across a broader area, which allows for better balance and stability during operations. This makes it suitable not only for lifting but also for subsequently moving equipment or materials horizontally.

Spreader bars or lift beams can be attached to cranes or other lifting devices, facilitating operations that require both vertical and horizontal maneuverability. This capability is crucial in various engineering and construction applications where load handling efficiency is paramount.

Other components listed serve more specialized functions. A wrecking bar is primarily used for prying and demolition work, a cutter is designed for cutting materials rather than lifting, and a chain hoist is typically focused on lifting operations but does not pull horizontally in the same way a spreader does. The spreader's dual functionality is what distinguishes it in this context.
