The radio controls adopted by Greifenberg are the result of years of field experience concerning operational capacity and user ergonomics. They are conveniently usable with safety gloves, featuring an extremely robust "case" capable of withstanding drops and violent impacts. With the convenient shoulder strap, they can be held with one hand, and thanks to the buttons marked with specific icons, operations during use are extremely simple. A powerful battery guarantees operation for an entire working day, and additionally, the standard supply also includes a spare battery and a charger. The brain of the radio system is located in the key inserted into the remote control, where communication codes and protocols are stored.

From the remote control, it is possible to carry out all the operations normally performed from the machine's touch screen panel. In fact, it is possible to turn the diesel engine on and off, increase or decrease the speed of the ropes, set and update the end of the line or loading point, make adjustments outside the set parameters using the dedicated "by-pass" button, start the automatic work cycle to operate the machine autonomously, control traditional trolleys by opening and closing the blocks on the ropes, and also perform all operations on motorised trolleys by controlling both the motor and the lifting and lowering speed. Through the remote control, it is possible to set the maximum lifting point of the trolley so that the hook is not incorrectly raised too much, as well as the maximum unwinding of the rope, preventing the entire rope from being unwound from the trolley's drum. If the rope is shortened, it is possible to reset the maximum lifting point to update it to the new rope length. The same remote control can also integrate the management of Fortronics electronic shockers with an anti-accidental opening system.

The Radio System includes a perfectly coded and integrated radio frequency repeater. The remote controls can operate with one or more repeaters, allowing for an infinite working distance and, above all, enabling the overcoming of bumps, buildings, and any kind of obstacle, extending the operating range. The repeater is housed in a robust, small-sized casing, and inside it, a powerful rechargeable battery ensures operation even during a long working day. The repeater must be placed on the peaks of bumps or alongside structures to ensure good connectivity with both the transmitter and the receiver. Activation is very simple, performed with a single button, and the distance is reset with a click.

Greifenberg understands the external working conditions, with temperatures ranging from below freezing to scorching sun, snow, water, and humidity. The Radio System is not affected by the weather: IP 65 rating, selected components, contacts treated with anti-corrosive materials—these are the guarantees of a product designed for heavy-duty use. Maximum reliability ensures precise, timely, and irrefutable commands. Transmitters, repeaters, and receivers are ready for uninterrupted operation.

ATG, Automatic Travel Greifenberg, is the electronic control and management system, a true form of artificial intelligence, meaning the machine's ability to travel along a rope completely autonomously and in automatic cycle. The ATG system considers various critical points such as supports, potential load entanglements, excessive power demand when going uphill, overspeed during descents, deceleration and acceleration speeds, and updates to the loading point if necessary. It constantly coordinates the work with reactivity, precision, and accuracy.

To activate the ATG, it is necessary to teach the machine the two endpoints of the line, which are stored as the "start of the line" and "end of the line" using an intuitive procedure on the control panel. Then, it will be possible to store the points along the line where the supports are located, which will be interpreted as sensitive points. To achieve linear travel, the electronic system allows setting the distance at which we want to decelerate from the support and at what distance after passing the support we want to accelerate and return to normal speed. The distances and amount of deceleration can be set differently depending on which part of the journey is being made and how the entry to the supports is approached. For example, when carrying heavy loads downhill, it is necessary to gradually slow down at an appropriate distance, and after passing the support, the machine will quickly regain speed to avoid rope and load oscillations. Conversely, if the transport is uphill, it is enough to slow down close to the support as the weight and gravity already contribute to deceleration.

Everything is under control during the journey. The machine, thanks to its pressure transducers and position encoders, constantly monitors the effort. If it detects abnormal peaks (caused by snags or contrasts), it deactivates the automatic system, halting the journey while still allowing manual mode. The ATG function also allows updating the loading or unloading point via the radio control. When the transport needs to frequently change the arrival point to pick up or drop off material at different locations, simply activate the “store new end point” function directly from the remote control, and the machine will stop exactly at the specified location.

Information is everything. The "Smart Yarder" function, in addition to keeping you informed about everything your machine is doing, allows you to interact remotely directly from your smartphone, tablet, or PC. Smart Yarder accurately replicates everything that the Greifenberg infotainment system communicates through the machine's touch screen. Every single piece of information is transmitted and faithfully replicated on your device. But that's not all; it is also possible to write or modify settings and work programmes. A "mirroring" system that splits the control point without needing to access the machine itself. This innovation was introduced specifically to facilitate the adjustment of work parameters and to monitor the machine's status, such as the engine's rpm, fuel level, or AdBlue level. Access to this function is protected by a password to prevent external access. It is enough to activate the Wi-Fi function on your portable device and enter the secret code.

The machine, thanks to a powerful router with a transmitting antenna, remains constantly connected within a range of approximately 50 metres. This function is particularly appreciated by those who operate both Greifenberg equipment and another machine, such as a tractor, skidder, harvester, or excavator. Never again will you need to get in and out of your vehicle! Online controls, checks, and configurations allow you to stay at your command post, increasing comfort and productivity.

This type of display is at the top in terms of technology and reliability. It is weather-resistant, capable of withstanding rain and snow, and offers high brightness for excellent visibility even when exposed to direct sunlight. The display also boasts excellent definition with realistic colours that make reading easy, even at very oblique angles. The touchscreen is patented for use even with gloves, and all work menus can be accessed through physical buttons to change the screen view.

Every process is under control. It allows you to view data and set the machine’s parameters with maximum flexibility. From the control display, you can select the engine power, monitor fuel and AdBlue levels, check hydraulic system pressure, track the speed and position of the trolley, view the position and speed of each roller, check the brake status, see which roller is active, view alarm notifications, check the machine's maintenance status, and much more.

The line parameters can be entered with factory settings or can be traced in detail. For instance, slowing down when crossing shoes can be customised according to the direction of travel, whether uphill or downhill, and can be programmed both in distance and as a percentage of slowdown. There are infinite possibilities for use—intuitive, fast, and adaptable to various situations to tackle any daily activity.

Power only when you need it. Greifenberg machines are equipped with powerful engines that never stop, enabling efficient transport while reducing time and increasing daily productivity. Over-sized engines with high torque at low RPM allow for both high power output and sufficient torque for hydrostatic systems operating at low revolutions. The Eco Power system controls engine power delivery, RPM, and pump flow mapping. The selection of three available modes—Eco Power, Normal Power, and Full Power—adjusts the engine and hydrostatic transmission characteristics to suit your worksite needs.

If the loads are light and full power is not required, the “Eco Power” mode can be selected. This setting, in addition to being eco-friendly by reducing both noise and exhaust emissions, also saves up to 40% in fuel consumption, leading to lower costs and higher profitability. The “Normal Power” setting partially limits the diesel power and optimizes the pump flow rates, providing excellent translation speeds and strong acceleration during startup with a full load. Fuel consumption and emissions are kept low while work speed is increased—this is the most commonly used setting when transport needs align with the machine's average performance.

“Full Power” mode delivers the maximum performance. All the diesel power is available, and the hydrostatic system operates at peak performance, with the electronics demanding the most from the transmission in both speed and torque. The machine offers the highest performance in this mode, with greater power bursts and increased translation speeds. All the available power is at your fingertips, without limits.

The control of maximum speed and performance without worries or the risk of engine over-revving. Simple, fast, and effective. The electronic auto-retarder system simultaneously processes the speed of the cable, engine RPM, and the current speed request to provide the best performance. The operator only needs to set the maximum speed they wish to allow for the machine in the dedicated program. From that point on, the speed control system, combined with the power of the hydraulic system, constantly monitors all parameters, testing the speed and making continuous adjustments.

The result is a smooth and consistent control of speed, regardless of the load's incline. Even sudden changes, like crossing over the peaks or shoes, are handled with great care, avoiding jerks or shocks to the ropes. Greifenberg's auto-retarder is now in its third generation and has reached an advanced level of automation, making every transport faster and safer. In addition to the electronic management, the operator can manually engage the hydraulic retarder at any time to slow down the descent using the proportionality of the joystick.

Greifenberg machines and equipment that need to reach work positions without communication routes are designed with modular sections for quick disassembly, allowing the creation of units with a weight of less than 1100 kg. This feature makes it possible to transport them using conventional helicopters. Air transport reduces installation times, and the disassembly/assembly systems of the individual modules are designed to be simple, enabling the team to move the equipment quickly and safely.

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.

The same remote control can also integrate the management of Fortronics electronic chokers with an anti-accidental opening system.

The Radio System includes a perfectly encoded and integrated frequency repeater.
