Step #5: “Dimensions” Data entry
This menu contains crane dimensions that are necessary for the calculation of the load
on the hook, based on the hydraulic cylinder pressure. This data refers to the winch and
boom hoist cylinder geometry at the superstructure and some main boom dimensions.
Some or all of this information may be pre-loaded prior to delivery but all dimensions
should be verified and edited as required before proceeding. Units in use will be feet or
metres depending on the setting made for ‘calibration units’ in step #3, a reminder is
shown on the bottom line of this display. To enter a negative value, enter the numerical
value and press +/- to change to negative (only available if relevant).
Remember to save any changes made.
Please advise Rayco Wylie of any changes
required in this section.
Dimensions relating to boom tip attachments are stored in the chart file and are not
editable in this menu,
*see note 2 (page 16)
.
CL1 (full retract):
length of the main boom when fully retracted.
CL2 (full extend with extension):
length of the boom with all sections fully extended
including any manual or power pinned extension if fitted.
Special case:
For booms with two telescoping ranges eg mode A with top section
pinned closed and mode B with top section included in telescoping, set CL2 to max
boom length with top section closed.
CL2MR (full extend w/o extension):
length of the boom fully extended but with any
manual or power pinned extension retracted. Note: For full power booms without a
manual section
CL2
and
CL2MR
are the same value.
Special case:
for booms with two telescoping ranges as above, set CL2MR equal to
CL2.
CL3 (p2blh)
– horizontal distance between the boom foot pin and lift cylinder base
pin.
CL4 (p2blv)
– vertical distance between the boom foot pin and lift cylinder base pin.
CL7 (p2buh)
– distance between the boom foot pin and lift cylinder top pin parallel to
boom telescoping centerline.
CL8 (p2cb)
– vertical distance between the boom foot pin and the boom centerline
with the boom horizontal. Instead of using the boom centerline as a reference, It is
common to use the boom foot pin, in this case CL8 = 0 but ensure that CL9, CL10 and
CL11 all use the same reference.
CL9 (ra2cb)
– vertical distance between the lift cylinder top pin and the boom
centerline (or boom foot pin, see CL8) with the boom horizontal. If the boom
centerline is higher than the lift cylinder top pin, then the distance is positive,
otherwise it is negative.
CL10 -
vertical distance between the lower boom tip sheave pin (hook suspension
sheave) and the boom centerline (or boom foot pin, see CL8) with the boom
horizontal.
