The single girder overhead crane is one of the most commonly used types of light bridge cranes. It is widely applied in workshops, warehouses, and production plants where light to medium-duty lifting is required. This crane generally adopts a single beam design, making it a cost-effective choice compared to double girder models. Despite its lighter structure, it delivers reliable lifting performance with the option of using either a wire rope electric hoist or a chain hoist. To enhance safety, the lifting mechanism is equipped with overload protection and lifting limit protection, which automatically cuts off power when the hoist reaches its upper or lower limit, preventing accidents and ensuring smooth operation.
Configurations and Applications
The most common setup for a single girder overhead crane is the top-running design, where the end trucks travel along the top of a runway system. For different applications, under-running versions are also available, and for heavier workloads, a double girder electric overhead crane may be selected. One major advantage of the single girder design is its lower production cost. With less material required and simpler fabrication, it offers an affordable yet dependable lifting solution. This makes it a popular option for small to medium workshops, as well as industries that rely on standard 10 ton overhead cranes for daily lifting needs.
Key Components of an Overhead Bridge Crane
To better understand the operation of an electric overhead crane, it is essential to look at its major components:
♦Bridge: The main load-bearing beam on which the hoist and trolley move. In a single girder system, this consists of one strong girder designed to carry loads efficiently while keeping the crane lightweight.
♦Runway: Parallel beams that support the bridge, allowing it to travel smoothly across the working area. The length of the runway determines the crane’s operational coverage.
♦End Trucks: These are mounted at both ends of the bridge and drive it along the runway. Built with precision, end trucks ensure stability and accurate positioning of the crane during operation.
♦Control Panel: The central system for managing crane functions, from hoisting to traveling. Modern control panels allow precise and safe handling, often integrating variable frequency drives for smoother operation.
♦Hoist: The hoist provides the lifting action and can be either a wire rope or chain type. For light-duty applications, chain hoists are often sufficient, while a 10 ton overhead crane typically requires a wire rope hoist for strength and efficiency.
♦Hook: A robust component that connects directly to the load. It is designed for strength, safety, and ease of attachment to various lifting gear.
♦Trolley: Mounted on the bridge, the trolley moves the hoist and hook side to side, enabling flexibility in positioning loads. Together with the bridge and runway, it ensures three-dimensional load movement.
