Question 1

What are the main components of an overhead bridge crane?

Accepted Answer

An overhead bridge crane consists of several core components, including the bridge structure, runway system, end trucks, hoist, trolley, and lifting mechanisms. Together, these components allow the crane to lift loads vertically and move them horizontally across the work area.

Question 2

What is the difference between a top-running and an under-hung bridge crane?

Accepted Answer

A top-running bridge crane travels on rails mounted on top of runway beams and is typically used for higher-capacity applications. An under-hung bridge crane is suspended from the bottom of the runway structure and is often selected when building constraints limit available height or when lighter loads are handled.

Question 3

How is the lifting capacity of an overhead crane determined?

Accepted Answer

Lifting capacity is determined by factors such as the weight of the load, the span and width of the crane, the type of hoist used, and the duty cycle. All crane components must be designed to support the specified load safely and consistently.

Question 4

What type of hoist is used on an overhead bridge crane?
