The C-stab is an online application that makes it easy
to calculate a preliminary stability diagram based on the Users choice of crane
configuration, stabiliser system and vehicle
parameters. This to match crane, stabiliser system and
vehicle for the purpose in question.
C-stab is mainly developed to draw stability charts
based on the Users choice configuration. However, it can also be used for some
other tasks, such as drawing the stability chart based on a SAC-file and saving
the selected installation parameters in a SAV-file which after that can be fed
into a SPACE box with help of the Terminal Program to change some installation
parameters for a crane mounted on a vehicle in order to optimize stability.
Simplified, there are three ways of using C-stab.
·
Start C-stab from C-office and set all crane, vehicle
and stabiliser system settings manually.
·
Start C-stab from C-office and import all crane,
vehicle and stabiliser system settings from a SAC-file
·
Start C-stab fromTrailerWin
You need to select the desired crane and its SAC-file
before starting an application in C-stab. There are three search alternatives to get the
desired SAC-file,
Serial
number
,
SAC-file
or
Selecting crane from list
.
In the list “Selected Configuration” the selected
crane, jib (
if fitted)
and
its serial number is shown.
Write the serial number of the crane in question in
the search field. Press “Go” to get the associated SAC-file. If you don´t know
the serial number you can go to an extended search view by pressing the
magnifying glass. Now it is possible to search for SAC-files created by a
specific user (
Uploaded
by
) and/or within a range of
Serial numbers
,
Crane models
,

s.
The different
search options can be used separately or together to refine the search result. The
control
Only
latest SAC-file
lets
you choose whether to show all SAC-files found or only the latest revision. Found
SAC-files are listed at the bottom of the page. Click the desired file to open
it.
NOTE!
Only files intended for the current user will be
listed.
This is a control that lets you decide if you want to
see all the SAC-files or only the latest revision. As default the control is
set to No. Click the control to switch setting.
Write the username of the user in question in the
field. By pressing the “Me” button you easily chose your own user name. Press
the search button to get a list of SAC-files created by that specific user.
Double click desired file in the list to select the SAC-file.
Write the first serial number in the left field and
the last serial number in the right field. Press the search button to search
for SAC-files within that range of crane serial numbers. Double click desired
file in the list to select the SAC-file. Example:
We want to find all cranes with serial number1058xxxxx. Write 1058 in the left
field and 1059 in the right. Press the search button and get a list of all
serial numbers beginning with 1058.
Write the first model name in the left field and the
last model name in the right field. Press the search button to search for SAC-files
within that range of crane models. Double click desired file in the list to
select the SAC-file. Example: We
want to find all cranes in the product range X-HiPro
192 to XS 322 HiPro. Write X-HiPro
192 in the left field and XS 322 HiPro in the right.
Press the search button and get a list of all products in that range.
Save date is the date when the SAC-file originally was
uploaded to C-Space. Write
the first date in the left field and the last date in the right field. Press
the search button to search for SAC-files within that range of save dates.
Double click desired file in the list to select the SAC-file.
The SAC-date is the date that the SAC-file was most
recently edited and saved. Write
the first date in the left field and the last date in the right field. Press
the search button to search for SAC-files within that range of SAC-dates.
Double click desired file in the list to select the SAC-file.
Press the Select file button to select a locally
stored SAC-file. Chose a desired SAC-file in the bowser window and click the
Open button.
Chose from different alternatives in the drop down
menus. The red warning signs are replaced with green ticks as the selections
are made. Depending on selections made, one or several red warning signs can be
replaced with green ticks. If no selections are available, the space for the
warning sign/green ticks will be left blank. You can make the selections in the
different drop down menus in the order of your choice. When all the red warning
signs are gone, click OK to get the SAC-file.
Chose the desired crane model.
Chose the desired control system.
Chose the desired boom system.
Select the desired boom extensions.
Select the desired jib.
Select the desired jib extensions.
Select the desired crane base.
Select the desired stabiliser
extension.
Select the desired stabiliser
leg.
With this control you can chose whether to keep or
dispose previous truck settings. The control is set to No as default. Click the
control to change it to Yes.
Click the garbage can to clear all the selections made
in the dialog.
The crane-data needed for calculating the preliminary
stability diagram is stored in a SAC-file. At the right of the Hiab
Applications window you´ll find the Selected Configuration. To change the
selected configuration, see section
Select
crane
.
Start the C-stab application by clicking the C- stab icon.
The preliminary stability diagram of the selected crane is shown. At the top
left corner there is a control for choosing if the configuration has ballast or
not and on configurations with jib applicable, a control for choosing if the
crane is equipped with jib or not. Click the controls to get the desired
settings. On the left there are several buttons for navigation between
different menus for setting of parameters, printing diagrams and saving
projects. At the start of C-stab, the menu
Stability diagram
is
shown. Some menus in the list below are optional.

Around the graph there are sections K1, K2, K3 and so
on. In these sections, the safety factor “K” is set. It´s one safety factor for
each tipping line i.e. the number of safety factors will vary depending on the
configuration of the crane. As standard the safety factor is set to 140 (+40%
safety factor). The Safety factors should only be changed after stability test.
The diagram shows the crane capacity
in
percent
depending
on the outreach of the stabiliser extensions. Each line correspond to some stabiliser extensions positions (0%, 40%, 60%, 80%, 100%)
Moving the
cursor in the diagram simulates the crane slewing, a popup window shows the crane
angle and current crane capacity for different degree of extension of the stabiliser systems. The crane capacity is specified in
percentage of the maximum capacity. The degree of extension is specified in
percentage of maximum extension.
Press this button to update the diagram after changing
any settings.
