CRANE.WIZCO
(Requires GHS with Crane Module) |
|
While the BOOM command is a convenient means of
locating the weights of various crane elements—converting
locations you give in crane coordinates into ship coordinates—it
is only one step of many needed to completely model a real-world crane.
The Crane Module and specifically the CRANE.WIZCO wizard makes the task of crane modeling relatively easy. It accommodates pedestal-mounted cranes as well as cranes based on the deck, providing several ways of distributing weights for shear and bending calculations. Knuckle booms as well as fixed-angle jibs are handled. Multiple hooks are provided for. A nice feature of the Crane Module is the manipulation of graphics to give visual verification of load locations. Here's the opening dialog of CRANE.WIZCO: |
|
| The green button brings up the main setup dialog for defining all the relevant details of geometry, weights, and capacity tables: |
|
| A separate capacity table for each hook is provided for: |
|
| The Crane Module can create a graphical representation of the boom and quite a few other details as well: |
|
|
|
| Useful output at a particular condition is presented in the Load Editor: |
|
| Several stability criteria are available: |
|
| Also available is a table showing results over a range of azimuth angles: |
|
| For what it's worth, the Crane Module will draw the locus of the hook at a given boom elevation angle: |
|
| It's fun to play with the dialogs and try things out. Just in case documentation is needed, the Crane Module manual is available. |
