Electrical Engineering XYZ MCQs
What type of electrical drive is used in cranes:
- Group
- Individual
- Both 1 and 2
- Multi-motor
Correct answer: 4. Multi-motor
Explanation: In the context of cranes, a multi-motor drive system refers to a setup where multiple motors are employed for driving different parts or functions of the crane. This could include motors for hoisting, trolley travel, and crane travel, among others. Each motor is dedicated to a specific task, allowing for efficient and controlled movement of the crane.
While “group drive” and “individual drive” are also valid concepts in crane operation, “multi-motor” encompasses both approaches as it implies the use of multiple motors regardless of whether they are synchronized as a group or controlled individually.
Therefore, “multi-motor” is the most encompassing and accurate term to describe the type of electrical drive used in cranes.
