HSM Forestry Machines

The remote controls adopted by Greifenberg are the result of years of field experience regarding operating range and ergonomic use. Designed for comfortable handling even with safety gloves, they feature an extremely robust case capable of withstanding drops and heavy impacts. With a convenient shoulder strap, they can be operated with just one hand, and thanks to buttons marked with specific icons, manoeuvres during use are extremely simple. A powerful battery ensures operation for an entire working day; additionally, the standard supply includes a spare battery and a charger. The brain of the radio system is housed in the key inserted into the remote control, where communication codes and protocols are stored.

All operations normally performed via the machine’s touchscreen panel can be carried out from the remote control. It allows users to start and stop the diesel engine, increase or decrease cable speed, set and update the end-of-line or loading point, make movements outside preset parameters using the dedicated “bypass” button, initiate the automatic work cycle to enable autonomous operation, control traditional trolleys by opening and closing the cable locks, and manage motorised trolleys by adjusting both the engine and the lifting/lowering speed.

The remote control can also set the maximum lifting point for the trolley to prevent accidental over-raising of the hook, as well as the maximum cable unwinding limit, ensuring the drum retains an adequate amount of cable. If the cable length is adjusted, the maximum lifting point can be reconfigured to match the new cable length. Additionally, the same remote control can integrate the management of Fortronics electronic chokers with an anti-accidental opening system.

The Radio System includes a fully coded and integrated radio frequency repeater. The remote controls can operate with one or multiple repeaters, effectively extending the working range infinitely and allowing signals to overcome hills, buildings, or any other obstacles. The repeater is housed in a compact yet sturdy casing, containing a powerful rechargeable battery that supports intensive daily operation. To ensure optimal connectivity between the transmitter and receiver, the repeater should be placed at the peaks of hills or at the sides of structures. Activation is straightforward, requiring just a single button press, while the working range can be reset with a simple click.

Greifenberg understands the challenges of working in outdoor conditions, with temperatures ranging from sub-zero to scorching heat, as well as exposure to snow, rain, and humidity. The Radio System is built to withstand the elements: rated IP65, featuring carefully selected components and contacts treated with anti-oxidation materials. These features guarantee a product designed for demanding applications, delivering maximum reliability to ensure precise, timely, and indisputable commands. Transmitters, repeaters, and receivers are ready for uninterrupted operation.

ATG – Automatic Travel Greifenberg is an advanced electronic control and management system, effectively an artificial intelligence that enables the machine to autonomously travel along the cable route in a fully automated cycle. The ATG system takes into account critical factors such as supports, potential load entanglements, excessive power demand when ascending, over-revving when descending, deceleration and acceleration speeds, and load point updates when necessary. It continuously coordinates operations with responsiveness, precision, and accuracy.

To activate ATG, the machine must first recognise and store the two extreme points of the line, which are registered as the "start" and "end" of the route through an intuitive procedure on the control panel. Once these are set, users can mark the positions of any supports along the route, which the system will interpret as sensitive points. To ensure smooth travel, the electronic system allows users to set deceleration distances before a support and acceleration distances after passing it, returning to the normal operating speed. These distances and the number of slow-down points can be adjusted based on the direction of travel and the approach to supports.

For instance, when transporting heavy loads downhill, a gradual deceleration at an appropriate distance is necessary, followed by a quick acceleration after passing the support to prevent cable and load oscillations. Conversely, when travelling uphill, a slowdown is only needed just before the support, as the weight and gravity naturally contribute to the deceleration.

Throughout the journey, the machine maintains full control via pressure transducers and position encoders, constantly monitoring strain levels. If it detects abnormal peaks caused by obstructions or resistance, the system automatically deactivates, stopping travel but keeping manual operation available at all times.

The ATG function also allows the loading or unloading point to be updated via the radio control. When frequent changes to the drop-off or pick-up location are required, the operator can simply activate the "save new endpoint" function from the remote control. The machine will then stop exactly at the newly designated location.

Total control, verification, and statistics. Every alarm, abnormal use, and operation outside the parameters are automatically recorded and stored in a dedicated memory. Data such as engine over-revving, overpressures, overspeed, oil and water temperature alarms, etc., are immediately recorded. It will be easy for the owner to monitor how the machine is used, both by their own staff and in the case of rental to third parties. Even for technical service interventions, everything becomes faster, limiting management costs. Information serving the durability and maintenance.

Our technicians with you, whenever you need, at your site to help you solve problems. Through remote assistance, simply activate a GPRS connection and allow access to your equipment. This always happens and exclusively with the operator's authorisation to the machine. Once connected, our electronic and hydraulic technicians can work on the machine as if they were right there on site. Maximum intervention speed and reduction of costs and waiting times. The innovation of safety always by your side.
