With the new electronically controlled ecDrive (Electronic Controlled Drive) drive, the 1390 can be driven and used as needed. To this end, Weidemann has implemented four different driving modes. Auto mode guarantees typical loader performance at 100%. In Eco mode, the engine speed is reduced to 2,200 rpm after reaching the desired vehicle speed, reducing noise and saving fuel, as well as user load and costs. However, in Eco mode the travel drive also has full power.

The other two optional driving modes have been specially designed for the use of hydraulic attachments or optimized execution of the Y load cycle. In the so-called Attachment mode, the use of attachments is made easier. The number of revolutions of the diesel engine is adjusted with the manual throttle and the travel speed is regulated with the accelerator pedal or the cruise control. With its help, speeds can be set very precisely in steps of 0.10 km / h via the display. This is a cruise control function. Thus, a constant feed for the implement is guaranteed. If the load on the implement is too high (for example, several pieces in front of a brush cutter), the machine automatically reduces speed to provide the most power possible to the implement. Once the load has been removed, it is regulated back to the preset speed on the machine. However, if you want to drive or reverse more quickly, you can override this function at any time by pressing the foot pedal and the machine will run at full speed.

M-Drive mode is the right choice for optimal execution of short-stroke load cycles, known as Y-load cycles: The number of revolutions of the diesel engine is adjusted with the manual throttle and the travel speed or pressure Controls are controlled with the accelerator pedal or pressure control. This eliminates the need for crawling and supports fast Y-charge cycles.

With these new driving modes, the 1390 and the amount of hydraulic oil for the various attachments can be dosed and controlled with great precision in the application. This makes the use of implements and loading tasks much more efficient and comfortable.

The new electric parking brake offers an Auto Hold and Hill Hold function. The brake is activated automatically when the machine is stopped, the direction of travel is put in neutral, the driver leaves the seat or the engine stops. The electric parking brake is also released automatically when the machine is started with the accelerator pedal. Of course, the brake can also be activated or deactivated manually via a switch. Thanks to these automatic functions, maximum safety is achieved together with high comfort.

Weidemann offers the right kinematics for each machine size. The 1390 comes standard with P-kinematics, which impresses with precise parallel guidance throughout the entire lift range. A longer oscillating version of the P-kinematics is also optionally available, increasing the lift height by 20 cm. In addition, P-Z kinematics, which is a combination of P-kinematics and Z-kinematics, is also available. It achieves considerable breakout and lifting forces while providing precise parallel motion.

The standard built-in Flat Face hydraulic couplings are easy to clean and ensure less soiling throughout the hydraulic system. When coupling the hydraulic hoses, there is hardly any leakage, so hands, machine, implement and ground surface remain clean. Hydraulic Flat Face couplings allow attachments to be attached even under pressure, saving time. All types of couplings are mounted on the same partition and are therefore easily accessible.

To further facilitate coupling and uncoupling of hydraulic attachments, it also incorporates the pressure relief function of the third control circuit, which is easily accessible from the front of the loader arm.

The interior of the machine has been fully developed with a color operating concept. Its ergonomic and comfortable driver's position offers a clear layout of the switches based on a color scheme. Its ergonomic and comfortable driver's position offers a clear layout of the switches based on a color scheme. All control elements are easily accessible and the operator always has the most important information on the machine in view on a well-structured display. The height and tilt of the steering wheel can be individually configured according to the operator's needs. This ensures that all drivers can use the machine ergonomically and without fatigue. The excellent clarity of the previous model has been further improved, for example, the roof section with protective grille has been enlarged on both the protective roof and in the cab to ensure perfect visibility of the work area from above. The machine already has a series of LED work lights (2 in the front and 1 in the rear) with 1,000 lumens each. Illumination can be further enhanced to meet different requirements by additional work lights with 2,000 lumens each, allowing for safer and individually tailored machine work in the dark. Good lighting of the work area allows the driver to work with the machine for longer without tiring.
