The radio controllers used by Greifenberg are the result of years of field experience concerning operational range and ergonomic use. They are comfortably usable with safety gloves and feature 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 buttons marked with specific icons, operations during use are incredibly simple. A powerful battery ensures a full day of work, and 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 codes and communication protocols are stored.

From the remote control, it is possible to perform all the operations normally carried out from the machine's touchscreen panel. In fact, it is possible to turn the diesel engine on and off, increase or decrease the speed of the cables, set and update the end line or loading point, make movements outside the set parameters via the dedicated "bypass" button, start the automatic work cycle by making the machine operate autonomously, control traditional trolleys by opening and closing the blocks on the cables, 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 to prevent the hook from being raised too much, as well as the maximum unwinding of the cable, avoiding unwinding the entire cable wrapped on the trolley's drum. If the cable is shortened, it is possible to reset the maximum lifting point, updating it to the new length of the cable. 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 coded and integrated radio frequency repeater. The radio controllers can operate with one or more repeaters, allowing the working distance to be infinite and, most importantly, capable of overcoming bumps, buildings, and obstacles of any kind, thereby extending the operational range. The repeater is housed in a small, sturdy casing, and inside, a powerful rechargeable battery ensures operation even during an intense working day. The repeater should be placed at the peaks of bumps or beside the structures so that it establishes a good connection both with the transmitter and the receiver. The activation is very simple, carried out with a single button, and the distance is reset with one 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 elements: with an IP65 rating, selected components, and contacts treated with anti-oxidant materials, these are the guarantees of a product designed for heavy-duty work. Maximum reliability ensures precise, timely, and irrefutable commands. Transmitters, repeaters, and receivers are ready for uninterrupted work.

ATG, Automatic Travel Greifenberg, is the electronic control and management system, a true form of artificial intelligence, meaning the machine's ability to carry out cable journeys completely autonomously and in automatic cycle. The ATG system takes into account various critical points such as supports, potential load entanglements, excessive power demand when climbing, over-revving during descents, deceleration and acceleration speeds, and the updating of the loading point if necessary. It constantly coordinates the work with reactivity, precision, and accuracy.

To activate the ATG, the two extreme points of the line must first be recognised by the machine, which are then stored as the "start of line" and "end of line" using an intuitive procedure on the control panel. Subsequently, 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 a smooth translation, the electronic system allows you to set at which distance from the support you want to slow down and at which distance after passing the support you want to reaccelerate and return to normal speed. Distances and the amount of deceleration can be set differently depending on the direction of travel and the entry to the supports. In fact, when transporting heavy loads downhill, it is necessary to gradually slow down at a proper distance, while after passing the support, speed is quickly regained to prevent cable and load oscillation. Conversely, if the transport is going uphill, it is sufficient to slow down near the support, as the weight and gravity already help to decelerate.

Everything is under control during the journey; in fact, the machine, thanks to its pressure transducers and position encoders, constantly monitors the effort, and if it detects abnormal peaks (caused by jamming or resistance), it deactivates the automatic system, stopping the journey, but always making it available in manual mode. The ATG function also allows you to update the loading or unloading point via the radio control. When transport needs to change the arrival point frequently 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 its journey exactly at the specified location.

The colour display for machine and line data provides greater accessibility, better intuition at first glance, ease of line parameterisation, and a simplified procedure for synchronising the trolley remote controls. The new series of displays allows quick checks, providing the operator with constant updates on position, effort, shoe position, motor rotations, fuel consumption, and fuel levels. The most important data is displayed both in analogue and digital formats to enhance the immediacy of reading.

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.
