Rocky Mountain Crane Service Logs
The crane lost eception with the remote and shutoff. The operator tried to restart and it would not restart. The operator took a picture of the following code.
The code 0x 0400 means the remote is asked to start (restart), but there is a function being applied at the same time. The operator was in mid-swing when it lost reception and the operator did not release the joystick when he tried to restart. The picture shows this.
Customer called and crane won’t swing. Crane will hoist and trolley, but no swing. Error code “E 705”. Slowing gear safety device. Thaddeus was able to FaceTime with customer and found slew drive circuit breaker was tripped.
1917.46(a)(1)(ii)
The accuracy of the load indicating device, weight-moment device, or overload protection device shall be such that any indicated load (or limit), including the sum of actual weight hoisted and additional equipment or “add ons” such as slings, sensors, blocks, etc., is within the range between 95 percent (5 percent underload) and 110 percent (10 percent overload) of the actual true total load. Such accuracy shall be required over the range of daily operating variables reasonably anticipated under the conditions of use.
Need to make sure you pull down on the cable that is attached to the jib release pin while folding up jib. It can get stuck and not slide properly and will bend plate. Which won’t latch properly.
When trying to fold the jib out it would stop and throw an error on the remote E 2651. Which means Torque limit motor reached. When using the motor it was putting out 11 to 15 amps before kicking out. A good motor at full speed puts out 5to 8 amps while working properly. You can find your amp pull right on the drive +k-T1. Replaced aux motor and was drawing 7 amps
Message E1514 indicates faulty display, however it could be that the CANbus system is open, and the display is the first component. Check the “T” which should be moved to the load pin . In this case the pins were bent on the Anemometer, and needed replaced.
