They simply lay the stone down, chiseled out the column, then stood it up via an A frame, however the Romans did have cranes, (not the massive things of today) but mobile wooden ones with counter weights at the back that operated on a system of pulleys (they even had cranes that operated on water)

Q:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
2 tower cranes (tower crane) referred to as tower cranes, also known as tower cranes, originated in Western europe. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..Has a good safety device 3, tower crane, such as lifting weight limiter, amplitude limiter, height limiter and load torque limiter limiting device, and travel limit switchestower lights wind instrument, wind clip rail device ladders athletic supporter circlewalkways and railings.

Q:How are those really tall construction cranes assembled ???
I assume you are talking about a tower crane. From a distance, it looks like a T with one side shorter than the other. First, you need a good foundation for the crane to sit on. Next, you have a large mobile crane. With the mobile crane, you construct the tower (metal framing going up), the cab (where the operator sits and the motors), the boom (the mast out front) and the counter-weights (on the side opposite the boom). For the most part, this will get you a tower crane that will be about 200 feet above the ground. Most tower cranes today are self-jumping. Once you are ready to jump the tower crame (i.e. insert another section of the metal frame) there are hyraulics that lift the boom, cap and counterwieghts. This will create a gap in the metal frame. The tower crane will then pick up a section of frame and hoist it up and the ironworkers will slide it into place. The top section will be lowered down onto the new frame piece. The hydraulic jacks then get re-attached higher up to continue the jumping process. That is how you get a crane to build a 50+ soty building. By the way, once the crane is about 700 feet in the air, (if you have the stomach for it), it is a blast to ride out to the end of the boom.
