The excavators are connected by a single cable. The remote controlled carriage moves thanks to the cable deviation. The cable deviation allows controlling tree hauling safely downhill. The force of gravity used for tree hauling downhill reduces by 40% operation costs.
Other advantages:
Excavator's mobility, because a fixed anchorage is not needed.
When the carriage is operating, the excavators and winch are in static mode since the designed concept is to only operate carriage after installation of equipment is complete. Thus, this contributes to a reduction in cost for example in personnel required, in equipment wear and tear and in fuel especially when operating downhill.
The carriage chariot consumes less fuel, an average 25 liters per day.
