Which of the following is NOT a type of non-cab operated crane?

The non-cab operated cranes are designed for specific tasks in material handling, and understanding their categories helps clarify their functionalities and operations. A counterweight crane is typically classified among operated cranes, particularly those requiring a cab for operator control. This classification stems from the design and operational requirements of counterweight cranes, which are equipped to manage heavy loads with the support of additional weights.

In contrast, gantry cranes, jib cranes, and hoists are designed to operate without a cab. Gantry cranes often move along a track and are utilized for lifting and transporting heavy loads horizontally and vertically. Jib cranes provide a rotating arm or boom, which allows for movement in multiple directions without requiring a cab. Hoists, while basic in nature, perform the essential function of lifting loads vertically and can be used in various settings, adapting to different load capacities and operational needs.

Understanding the structural design and operational characteristics of these cranes reinforces the distinction between non-cab operated cranes and those requiring a cab, clarifying the choice made in this question.
