On cranes, reservoirs are typically located on which side?

• A. The left side
• B. The right side
• C. Top
• D. Bottom

Answer: (B)

The main idea here is how hydraulic systems are designed for balance, accessibility, and reliable fluid flow. The reservoir feeds the hydraulic pump and must be easy to inspect, service, and replace fluid, while also fitting into the machine’s weight distribution without complicating hose routing. Placing the reservoir on the right side of the crane meets these goals: it keeps the reservoir close to the hydraulic pump so hoses can be shorter and less complex, and it positions the reservoir away from the operator’s immediate work area while staying clear of the boom’s swing path. Top placement would expose the oil to heat and sunlight and risk degradation or leaks in a busy area; bottom placement would make inspection and maintenance difficult; left-side placement could complicate hose routing and balance in many crane layouts. For these practical reasons, the right side has become the typical location.
