Which do you prefer: a single girder overhead crane or a double girder overhead crane? What are the similarities, variations, and unique characteristics of each type of overhead crane? Get insight from the leading single and double girder overhead cranes suppliers about the operation features, working circumstances, production cost, and mechanical attributes of a single girder overhead crane to a double girder overhead crane.
Basics about Overhead Cranes
An overhead crane, sometimes known as a bridge crane, is a sort of crane usually used in manufacturing and industrial workplaces. An overhead crane usually comprises parallel runways connected by a travelling bridge. A crane’s hoist, or lifting gear, glides along the bridge.
In general, there are two types of overhead cranes: single girder overhead cranes and double girder overhead cranes. So, how do you pick one? This is a concern that continues to baffle most customers.
Some Distinct Qualities of Electric Single-Girder Overhead Crane
Electric single-beam overhead cranes can carry a variety of loads while in use (such as dynamic, static, alternating, impact, and vibration, etc.). The intensity of the weight is not just indicated in the load characteristics during the operation. It demonstrates changing traits in terms of diversity and various working conditions during the operation.
When the movement state changes, the electric single-beam overhead crane generates a dynamic load. It serves as a crucial basis for intensity assessments and has an impact on stress calculations as well.
The variable load effect amplifies the initial load capacity value when the motion status of the equipment shifts, and the augmented component is the dynamic load. In an adjustable speed motion, the dynamic load incorporates the frictional load produced by the structural self-weight as well as the lifting force.
The inertial load and the impact load enable the metal structure and component to be flexible. The impact strain is created by the impact of the wheel on the bumper due to an inconsistent track connection or moving element. Vibrating loads are generated by the system.
The single-beam suspension hoisting is only susceptible to the tensile stress of the lifting load and the deadweight load when the electric single-beam overhead crane is in a steady state or a good performance of the proposed state. The crane’s metal frame, electrical and mechanical equipment, and the weight of the storage container or belt connected to the machinery, as well as the commodities on it, all contribute to the deadweight weight.
Differences in Construction Characteristics
The single girder type overhead crane has a lower dead load and a basic structure that allows for quick assembly, disassemble, and performance.
Because double girder overhead cranes are heavier and have more intricate structural elements, they are more difficult to set up than single girder cranes.
Single girder overhead cranes are commonly utilized in confined areas with short spans, minimal weight, and short working durations.
The double girder overhead crane is useful for large industrial facilities with a high working class that can adjust to hefty loads and large dimensions. Double girder usage is more widespread than single girder usage.
Single Girder Overhead Cranes Can Help You Meet Demands of Work
Single girder overhead cranes are the most common form of overhead crane and are suitable for lifting, hauling, and transporting goods. A single girder bridge crane is usually assumed of as a sort of light duty lifting equipment that fits well with CD1, MD1 type electric hoists. The single beam bridge hoist is commonly used in workshops, warehouses, and yards to keep up with the demands of work, safety and efficiency.
