Calibrating Load on the MAIN Winch (with Friction Compensation)
Note: Ensure that Hoist Up and Hoist Down switches have been fitted. Check for correct operation of
digital inputs (refer RCI System Configuration Documents in Attachments and 6.11 View Digital Inputs.
Step 1) Calibrating Light Main Load
a) The load used should be heavy enough to produce approximately 10% of the maximum
main winch line-pull,
b) The total weight of any lifting gear or tackle under the hook block (such as slings, lifting
frames, etc.) must be added to the weight of the light test load.
c) If a light test load is not available, the weight of the empty hook block may be used as light
load.
d) For some cranes where the hook block is considered part of the crane, use the empty hook
block as a light load use the value “0.0t” as light load.
e) Enter calibration mode, if not already activated, and select “Calibrate Light Main Load”.
f) Use the UP/DOWN keys to ramp the display to the required value (i.e., calculated light load
above).
g) Start hoisting up slowly.
h) Press ENTER to accept value. Stop hoisting.
i) Select “Calibrate Light Main Load”.
j) Use the UP/DOWN keys to ramp the display to the required value (i.e., calculated light load
above).
k) Start hoisting down slowly.
l) Press ENTER to accept value. Stop hoisting.
m) Proceed to next section “Calibrating Heavy Main Load”.
Step 2) Calibrating Heavy Main Load
a) The load used should be heavy enough to produce approximately 70% of the maximum
main winch line-pull, whilst staying within current SWL.
b) The total weight of any lifting gear or tackle under the hook block (such as slings, lifting
frames, etc.) must be added to the weight of the heavy test load.
c) Enter calibration mode, if not already activated, and select “Calibrate Heavy Main Load”.
d) Use the UP/DOWN keys to ramp the display to the required value (i.e., calculated heavy
load above).
e) Start hoisting up slowly.
f) Press ENTER to accept value. Stop hoisting.
g) Select “Calibrate Heavy Main Load”.
h) Use the UP/DOWN keys to ramp the display to the required value (i.e., calculated heavy
load above).
i) Start hoisting down slowly.
j) Press ENTER to accept value. Stop hoisting.
Step 3) Verify that the Main Load Calibration
a) Use the “VIEW CALIBRATED MAIN LOAD” function code.
7.4.9.
Calibrating Load on the AUX Winch (with Friction Compensation)
Step 1) Calibrating Light Aux Load
a) The load used should be heavy enough to produce approximately 10% of the maximum
aux winch line-pull,
b) The total weight of any lifting gear or tackle under the hook block (such as slings, lifting
frames, etc.) must be added to the weight of the light test load.
c) If a light test load is not available, the weight of the empty hook block may be used as light
load.
d) For some cranes where the hook block is considered part of the crane, use the empty hook
block as a light load use the value “0.0t” as light load.
e) Enter calibration mode, if not already activated, and select “Calibrate Light Aux Load”.
f) Use the UP/DOWN keys to ramp the display to the required value (i.e., calculated light load
above).
g) Start hoisting the load up slowly.
h) Press ENTER to accept value. Stop hoisting.
i) Select “Calibrate Light Aux Load”.
