Military Trucks
The smooth and effective transport of troops and goods is the main task of military trucks – regardless of whether those are militarized logistics vehicles or highly mobile military trucks. Despite the high mobility, these vehicles can get stuck. To ensure these trucks can free themselves from such awkward situations, they are equipped with self-recovery winches. The pulling force is aligned to the respective payload of the vehicle. Self-recovery winches usually have a pulling force of 70 – 120 kN, in some cases up to 150 kN. For logistic vehicles we normally use the ROTZLER TARVOS, a typical drum winch. The ROTZLER TREIBMATIC is used for higher tactical requirements. Depending on the installation situation of the carrier vehicle, both types of winches can be installed in the chassis frame as a center installation, or on the side of the vehicle’s frame. The installation is usually carried out with pull to the front. Solutions for single pull to the front and double pull to the rear are also available.

As a system partner, we do not only supply the winch, but also all necessary rope guiding parts, which we adapt precisely to the respective vehicle type. Various control options as well as a wide range of accessories, such as snatch blocks to double the pulling force, are also available.

Heavy-Duty Transporters
Winch systems on heavy-duty transporters have the task of pulling damaged vehicles onto the low-loader safely and in a controlled manner. A single winch with an appropriate pulling force, normally between 250 and 400 kN, is sufficient for this task. In most cases, not only loading of the low-loader via the winch is required. Rather, it is also about the controlled unloading of the low-loader. This is only possible with two winches. With the help of a deflection, the load is pulled off the low-loader with one winch, while the other winch secures the load. This is particularly important if the defective vehicle is pulled over the tipping point of the low-loader. Without using the second winch as a braking winch, there is a risk that the load will slip off the low-loader in an uncontrolled manner. Twin winch systems also offer unbeatable advantages when loading the low bed trailer. By pulling crosswise with both winches, the winch operator can precisely control and position the load. This enables the precise loading of a wrecked, damaged vehicle onto the low loader, even if it is not perfectly positioned in relation to the load. This cannot be solved with a single winch. Both ROTZLER TARVOS drum winches and the ROTZLER TREIBMATIC are used in the twin winch systems of ROTZLER. These winches have pulling forces of 200 or 250 kN. Both winches, placed next to each other, can be integrated into a modular support frame behind the driver’s cab of the truck. Installation on the low-loader is also conceivable. The modular base frame enables the system to be easily adapted to customer requirements. Depending on the needs, for example, an auxiliary winch for pulling out the rope of the main winches, storage boxes, a control stand, or other attachments can be integrated. A complete package of accessories such as a four-strand chain, shackles, etc. is also available.

Wheeled Armored Vehicles
Armored transport vehicles, whether they are used as group transport, command or supply vehicles, are highly mobile and protected vehicles. They are characterized by great operational mobility. To ensure this mobility, such vehicles are equipped with TREIBMATIC self-recovery winches. This allows the vehicle, should it get stuck, to recover itself without external help. The TREIBMATIC impresses with maximum flexibility when choosing the installation position. This enables solutions also in confined spaces. Usually, the winch is installed with a pull to the front. Pulling to the rear or a combination of pulling to the front and to the rear are also possible without making any compromises in the operation of the winch. We strive to always ensure accessibility for maintenance purposes. Our engineers and technicians support our customers in integration of the winch system into the overall vehicle concept. This applies to the mechanical integration, but also to hydraulic and electrical/electronic integration of the TREIBMATIC. In doing so, we make sure all advantages for the user come into play, but also the needs of the system supplier are fully taken into account.

Armored engineering and recovery vehicles are tasked with providing engineering support and recovering other vehicles. For this reason, they are equipped with a recovery winch. Usually, the winch is positioned inside the vehicle, but can also be placed outside the armored cell. This is the ideal application for the TREIBMATIC. It enables fast and effective recovery of damaged vehicles. Usable cable lengths of up to 170 m

offer an extremely large operating radius. Combined with the constant pulling force of the TREIBMATIC, this enables effective recovery over long distances. In addition to the structural advantages of the TREIBMATIC, the overall reach is also of the utmost importance in use. The benefits in regards to flexibly selectable installation position and accessibility for maintenance purposes apply as well.

Tracked Armored Vehicles
This vehicle category includes recovery tanks and armored engineering tanks. In armored recovery vehicles, the main winch is one of the core components of the entire vehicle system. The recovery tank has the task of recovering vehicles that are stuck, have had an accident or are defective. The predominantly used recovery winch is the TREIBMATIC. These winches are able to free even the heaviest vehicles from the most awkward situations. Constant pulling force, high rope lengths and precise operation are the most important characteristics for the user. When integrating the winch into the vehicle concept, the flexibility of the TREIBMATIC with regard to separating the winch and rope storage helps choosing the ideal installation position.

Twin winches are often used on armored engineers to recover other vehicles and to tear down or clear barricades and barriers. Both winches can be used individually or simultaneously to recover a vehicle or to tear down a barrier. These special applications require dedicated functionalities on winches. For example, the TREIBMATIC twin winch system in an engineering tank allows the rope to be pulled out with the vehicle. High rope lengths are of great advantage, especially for the diverse and often complex work that has to be carried out with an engineer tank. With a twin winch, the load can also be pulled away from the carrier vehicle in a controlled manner. By using a snatch block, one winch pulls the load away from the tank, while the second winch secures the load. This flexibility significantly expands the range of applications. In addition to the handling advantages mentioned, a twin winch system offers advantages for the system suppliers. The installation of the TREIBMATIC provides a high level of flexibility, especially when positioning the individual winches, and also enables good weight distribution.
System Integration

The integration of the winch system in the respective vehicle is of crucial importance for the project success. Qualified system engineers work together with our customers to develop the best possible solution for the winch installation. This applies to the optimal utilization of
the installation space through the appropriate positioning of the components, to the cable routing in the vehicle and to the ideal weight distribution with regard to the overall system.

Project Management
Experienced project managers accompany our customers through the duration of a project. They support, plan and control the entire process. For our customers they act as the interface when selecting the best solution, during the design phase and the verification of the prototypes up to the installation and commissioning of the complete system.

Control Technology
In addition to the system integration, the operation of the winch and the data communication with the vehicle is an essential component for optimal use of the entire system. From the simple control of a self-recovery winch to the control of a complete recovery system on a recovery vehicle, we offer all conceivable control options. Our digital control concepts based on CAN bus leave nothing to be desired. A great advantage for both the user and the system supplier.

Education and Training
ROTZLER offers a comprehensive education and training concept. Special courses for winch operators, but also maintenance and installation training is available and can be tailored to customer projects.
