What is the distinct feature of mobile cranes?

• A. Equipped with a means of propulsion or travel
• B. Fixed location
• C. Uses rails
• D. Has no cab

Answer: (A)

Mobility is the defining feature: mobile cranes can move under their own power to different job sites. They’re built on a wheeled or tracked chassis with a power source that lets them travel on roads and between locations while carrying or lifting loads. This ability to relocate quickly is what sets them apart from cranes that stay fixed in one spot or that run on rails. The presence of a cab isn’t the defining factor—some mobile cranes have cabs and some don’t—but the critical idea is the crane’s propulsion and travel capability, which enables on-site relocation.
