In the case of cable yarding, the RCC is set in the same manner as conventional bells. When the turn arrives at the landing, the yarder operator slacks off the rigging or carriage line and releases the chokers using a remote keypad mounted in the cab. The chokers can be all be released with the touch of one button, or individually. To release the choker bells individually color codes with fluorescent paint for identification purposes or hanging the chokers on the rigging (i.e. front=button 1, middle=button 2, rear=button 3) in such a way that the yarder engineer can identify them is necessary. Choker tension creates sufficient friction between the latch pin and arm to prevent accidental release when the logs are in the air.
The drawing above shows how a yarder operator might set up the choker system.
