What are the two major categories of construction drawings used in the elevator trade?

In the elevator trade, the two major categories of construction drawings are primarily mechanical and electrical. Mechanical drawings focus on the physical components of the elevator system, including the elevator car, hoisting equipment, and related mechanical systems. These drawings provide detailed specifications for assembly, installation, and maintenance of mechanical parts.

Electrical drawings, on the other hand, detail the wiring, circuits, and control systems required to operate the elevator efficiently. These diagrams are critical for ensuring that electrical components are correctly installed and function together seamlessly with the mechanical systems.

This division into mechanical and electrical drawings is essential as it ensures that both aspects of the elevator system are effectively designed and implemented, providing safe and reliable operation. The other categories, while relevant in broader contexts within construction, do not specifically pertain to the specialized needs and systems unique to elevator installations.
