We often see cranes as part of city skylines and construction jobs. The movement and hoisting capacity of these simple mechanical heavy machinery assemblies has to fit typically within engineering requirements for deflection and a space envelope.
Our team at Meadows Analysis performs a lot of design optimization and engineering certifications of cranes.
A latest one we are working on has a 100 foot span on the crane bridge! We have to analyze the deflections and ensure the beam sizes can support the 4 ton loads that will be required.
After we arrive at the CMA requirements, we will work on providing fabrication drawings which the customer can then use to get the crane built. They will have to account for the installation. The crane becomes part of the building it will reside in for material handling and heavy equipment movement.
The range of motion and tight envelope for movement will be part of the design constraints.
Cranes make operations and material handling easy and efficient. They are not only functional, but they are typically a long-term part of a structure and the considerations for long-term upkeep, maintenance and footprint have to be part of the engineering design and analysis project outputs.
Know of anyone that has cranes in their buildings?
