Question: 1 / 400

What types of power do Category 1 or 4 cranes generally use?

Electric or hydraulic power supplied by a diesel engine

Category 1 or 4 cranes primarily utilize electric or hydraulic power supplied by a diesel engine. This is because these cranes are often designed for heavy lifting and require reliable and robust power sources to operate their lifting mechanisms effectively. Diesel engines provide the necessary horsepower and torque to drive hydraulic pumps, allowing for smooth operation of the crane's hydraulic systems.

Electric power can also be a significant source for these cranes, particularly in applications where a continuous power supply is essential. The combination of electric and hydraulic systems ensures that the cranes can operate with precision and handle substantial loads safely, making them suitable for various heavy-duty applications in construction and industrial settings.

The other options involve power sources that either do not match the typical requirements of cranes in these categories or are less commonly used. For example, pneumatic power is typically used for lighter tools rather than heavy lifting, and water power is not a conventional source for cranes. This reinforces the importance of using reliable power sources that align with the operational needs of Category 1 and 4 cranes.
