cr2m (m.h. radius) – the radius of the main hoist drum from the center to the middle of
the hoist line layers. This distance is approximate and does not play a critical role in
load accuracy.
cl5m (p2mhh) – the horizontal distance between the center of main hoist drum and
boom pivot pin. If the drum is mounted on the boom, this dimension is zero.
cl6m (p2mhv) – the vertical distance between the center of main hoist drum and boom
pivot pin. If the drum is mounted on the boom, this dimension is zero.
cr22m – the radius of the boom base mounted, main hoist guide sheave, *see note 1.
cl28m – the vertical distance between the boom base mounted, main hoist guide
sheave and the boom pivot pin with the boom horizontal, *see note 1.
cl29m – the horizontal distance between the boom base mounted, main hoist guide
sheave and the boom pivot pin with the boom horizontal, *see note 1.
cr2a (a.h. radius) – the radius of the auxiliary hoist drum from the center to the middle
of the hoist line layers. This distance is approximate and does not play a critical role in
load accuracy.
cl5a (p2ahh) – the horizontal distance between the center of the auxiliary hoist drum
and boom pivot pin. If the drum is mounted on the boom, this dimension is zero.
cl6a (p2ahv) – the vertical distance between center of auxiliary hoist drum and boom
pivot pin. If the drum is mounted on the boom, this dimension is zero.
cr22a – the radius of the boom base mounted, auxiliary hoist guide sheave,*see note 1.
cl28a – the vertical distance between the boom base mounted, auxiliary hoist guide
sheave and the boom pivot pin with the boom horizontal, *see note 1.
cl29a – the horizontal distance between the boom base mounted, auxiliary hoist guide
sheave and the boom pivot pin with the boom horizontal, *see note 1.
Note 1: This option is rare and these values are generally set to zero. If a guide
sheave is fitted but mounted on the superstructure (not the boom) then the sheave is
treated as though it is the winch drum (see sketches).
To modify one of these variables, proceed as follows:
1- Use “
” or “
” to highlight line “-dimension” and press “
” to go to submenu.
2- Use “
” or “
” to highlight the required variable. Note: there are 5 pages.
3- Press “
” to edit the variable.
4- Use “
” or “
” to modify the value. Note: If you keep “?” pressed in, it will
accelerate the modification.
5- Press “
” to save the new value.
6- Repeat steps 1 to 5 for all the other variables.
7- Press #5 “ESC” to come back to the main calibration menu.
