Designing a shelter with a 25-ton capacity crane involves structural considerations to support the heavy load and movement of the crane. Below is a guide for creating the basic drawing and concepts for such a structure.

Key Elements of the Shelter with Crane:

1. Structural Framework:
   • The shelter framework needs to support the crane loads, including the crane’s self-weight, the live load from the crane operation, and dynamic loads.
   • Use steel columns and beams for the primary structure, typically designed to support the crane runway beams and tracks.
   • The structure must account for the clear span required for the crane to operate without obstruction.
2. Crane Runway Beams:
   • Crane runway beams are essential for supporting the crane bridge. These beams will need to be adequately designed to support both the vertical and horizontal forces from the crane.
   • Runway beams should be aligned on both sides of the shelter with adequate bracing to resist lateral loads.
   • Beam section size (I-beams, wide flange beams) should be calculated based on the 25T crane load and span.
3. Crane Rails:
   • Rails are mounted on top of the runway beams. These rails must be securely fixed, and the connection details should show clip arrangements for attaching the rails to the beams.
   • Indicate rail type, dimensions, and placement in the drawing, based on the span and crane wheel configuration.
4. Columns and Supports:
   • The structure needs steel columns to support the beams. The columns should be spaced according to the crane runway span.
   • Use box sections or H-columns, depending on the loading conditions, and ensure that base plates and anchor bolts are detailed properly for load transfer.
   • Consider the height and clearances needed for crane operation.
5. Crane Girder:
   • The crane girder should be designed to handle the vertical and dynamic loads from the crane’s operation, including lifting 25 tons.
   • Indicate whether it’s a single-girder or double-girder crane system.
6. Bracing Systems:
   • Bracing is necessary to provide lateral stability to the shelter and prevent lateral deflections from wind loads and crane operations.
   • Use cross-bracing or knee braces at the column-beam connections to resist lateral forces.
7. Roofing and Cladding:
   • The shelter should have a roof structure, typically trusses or purlins, supporting the roofing sheets. The roof should be strong enough to withstand wind loads.
   • Cladding material should be indicated for the sides if required, with details on how it’s attached to the frame.
8. Crane Details:
   • Show the crane type (e.g., EOT crane), its wheelbase, crab dimensions, and runway length.
   • Include a crane hook approach, clearances, and end stop positions for safe operation.
