Elevator Mechanic Practice Exam

The correct answer is the installation manual because the Design Basis Guideline (DBG) for the elevator car is typically outlined in this document. The installation manual provides comprehensive details on the specifications, design parameters, and requirements for the elevator system, including the car's components and functionality. This manual is essential for ensuring compliance with safety standards and for the proper installation of the elevator system.

The maintenance log, while crucial for tracking the performance and service history of the elevator, does not contain the foundational design information and specifications necessary to understand the car's design principles. The final layout or hoistway plan view drawing would illustrate how the elevator fits within a building structure but would not provide the detailed design criteria for the car itself. Safety guidelines are important for operational safety and maintenance but do not delve into the technical specifications or design basis for the elevator car.
