Remote control

Every function the crew needs for a quick, safe set-up is on the remote: the supports, raising the tower, the guy line drums and winch, the skyline and main line winches, the tensioning cylinder, carriage start and stop, the winch in the carriage, the automatic drive function, handing over radio control, and the horn.
