Trolley not running smooth and making metal on metal sounds.  The way that the trolley is pulled make the inner drivers side one wear out and needs to be replaced.

Operator called and said crane won’t move.  Turns out he turned the key in control panel for the 125% test.  This erases the scaling data.  What you have to do is turn scaling key and go through and make sure everything is check marked and then a check mark at the end and hit enter.  Once this is complete you can switch switch out of scaling and it will work.

 

Remote keeps kicking out and getting errors.  Swapped whole remote and works fine.  Going to get antenna extension from HBC to see if it will help signal strength.

When logging into the diagnostic menu, code is (month + date) + (hour + minutes)  example if it is 4/15 at 14:30…its (19) + (44) = 63  code will be 63 for one minute.  Hit the “+” 63 times to get to correct code

Wind speed not displayed on remote or control panel display. It is not enabled on the control panel. Follow instructions in manual 4-135. Login, next page, set, function key with anenometer displayed

Crane was oscillating when swinging to the left.

Only was happening when it was cold.

Changed out encoder.

Need snap ring pliers and lots of zip ties to do it.  Took about 1.5 hours

 

Scaled crane and went to do known load and horn just started honking.

Had 4 tower sections in and 45 degree avoidance on in the scaling process.  You can’t have 45 degree avoidance on with 4 tower section in unless you have central ballast.

Went back in and put x through 45 degree avoidance and it worked fine and was able to finish scaling

Went through scaling for crane and once in verification screen and hit ok horn honks continuously.

Then moved trolley back to min setting 3 m from tower and moved to next screen and hit min radius and it shut off
