Steep Land Harvesting development outputs in the pipeline

Twin Winch Tail Hold Carriage System  

The design and construction of the full sized working version of the remote controlled twin winch tail hold carriage has recently been completed with winches and hydraulics now installed. Initial tests have been undertaken and field trials are currently being planned. When fully commissioned, the system will be demonstrated to the forest industry. This innovative system has the potential to significantly improve the efficiency of cable extraction on steep land.

Teleoperated Felling Machine

The remote control system installed in the John Deere 909 feller buncher was demonstrated to the industry in October 2015 in Nelson. Since then further progress has been made to implement a full teleoperation control system into the John Deere 909 feller buncher. A remote operated mobile operator console with John Deere seat and pedals and video monitors has been constructed. Cameras mounted on the boom and head of the feller buncher will feed live video stream to the operator in the console.

Further progress has also been made in the remote control of Volvo EC290 mobile tail hold machine, with installation of the system, including cameras, underway. This will allow full operation of the tail hold machine from the hauler cab.

HarvestNav Update

Extension to the wider forest industry of the HarvestNav software application has continued during the quarter. To date 31 licences have been issued, and 18 units implemented across the industry. Version 2 of the software has been released which includes: ability to handle external GPS sensors to monitor all machines and crew positions on-screen; and integration of external tilt sensors for self-levelling machines.
