Rough and slippery road surface, rugged and dark environment, how can the fire brigade accomplish the task of reaching the site in eight minutes in the harsh geography of the Grevenbroich mine in Germany? The Germans gave their special Choices - Use the Allison Transmission and Fire Truck to retrofit the Iveco Trakker Construction Vehicle.

With huge chimneys in the sky, power plants and cooling towers are towering skyscrapers - in the triangle between Cologne, Neuss and Aachen. Although there are only 65,000 inhabitants, they have the "energy capital of Germany". Gryffindor Broig is called here.
The Gräfenbroich brown coal open-pit mine is located in the mountains near Cologne and its mining area is 48 square kilometers. All that has been there will be described in one sentence - everything is so great. However, with the exception of a 100-kilometre conveyor belt, there is hardly any formal way of getting to the outside world - only a gravel road, which can be called a road, has not been refurbished and paved. The German energy giant RWE Energy supplies 100 million tons of lignite annually to nearby power plants.
The Garzweiler fire brigade was responsible for providing fire and rescue services for the entire mining area. It was requested to arrive at the site within 8 minutes. The harsh environment and urgent tasks always plague the fire brigade. In order to solve these problems, the team recently added a special equipment - Iveco Trakker 190 construction vehicles. The fire brigade modified the Iveco Trakker 190 and added a fire truck to the top part of the gearbox. The gearbox used an Allison 3200 series gearbox with a retarder.

For Gartsweiler firefighters, the Allison transmission is almost indispensable. “Working on such rough roads, all-terrain vehicles using fully automatic transmissions have a huge safety advantage,†said Rudolf Niephaus, chief fire inspector and consumer captain of the Gatzelle mine. Says: “Our work in the open pit mining area is almost 365 days a day. The road conditions change almost every day. We spend a lot of time in the dark, on a slope with a height difference of 210 meters. In this situation Next, they can't be distracted by changing gears, but keep their hands on the steering wheel."
Engineers of Iveco Magirus visited the open pit mine in Gryffindor, and proposed a proposal for retrofitting on a construction vehicle instead of an ordinary vehicle chassis because of the robustness of the construction vehicle. Powerful design is more suitable for this occasion. In order to ensure maximum reliability and durability, unusual methods have also been adopted in the installation of gearboxes. In addition, to protect the transmission cooling system from the erosion damage of sand and mud on this non-road surface, gearbox components are installed in the upper part of the car and protected by steel plates.
The power output of the Allison transmission allows the engine to drive a 2400 litre tank pump and control the foam mixing tank. Allison transmissions have unique advantages for vehicles in such operating environments. These rescue vehicles are constantly on the job, not rushing to handle emergency situations, or patrolling and monitoring. These vehicles need to run 10,000 to 15,000 kilometers each year for 15 years in service. The advantage is that it has a torque converter that provides engine-to-gearbox coupling. It has a high speed at the start and a direct mechanical drive at high speeds. The buffer effect of this torque converter protects the powertrain from shocks and Wear, and Allison electronic control system can also ensure the best shift and eliminate driving errors. "There is no clutch loss because the Allison transmission does not use a dry clutch," added Neffs. "Allison considered the overall value of the purchase and it takes into account the operating costs of the entire vehicle life cycle."
Mine life
“The conveyor belt in the fourth gob of the crater caught fire!†“There was oil on the road!†“A dump truck and a wagon collided beside the conveyor belt!†These are all in Garzweiler every day. A typical call in the fire brigade. The mining area is constructed with a ladder platform, where the brown coal mining area is divided into six layers. In each leveling platform, shovel excavators operate on different deposition layers; in order to be able to quickly move from one level to another, a twenty percent slope is built between two adjacent levels. “These slopes were built to ensure that we arrived at the scene within 8 minutes of receiving the emergency call. Since there is 360 horsepower on the Iveco Trakker and the Allison automatic transmission is equipped, we can Labor can be opened up," Nevs explained.
“Because of power shifting and torque converter twisting, vehicles equipped with Allison transmissions can ride flat on steep slopes and on slippery roads with gravel, sand, and cinder. By means of the oscillation of the water in the tank Vehicles can easily pass through the sand. In such road conditions, vehicles using manual gearboxes must sink into sand and gravel, and they must think of ways to pull the vehicles out. I can't imagine how they can pass through.
“The Gartsweiler Fire Brigade needs high performance, strong power, reliable vehicles to reach every corner of the mine, and thanks to Allison fully automatic gearboxes, the vehicles are not damaged and do not require frequent maintenance.†Neves finally stressed.
About Garzweiler plant Fire Brigade
The lignite open-pit mine fire brigade is divided into three fire stations: the Garzweiler fire and rescue station, the Fortuna coal station fire station, and the fire station next to the conveyor belt. The newly purchased Iveco Trakker is deployed in a conveyor belt fire station. A total of 27 full-time firefighters and 80 auxiliary workers are responsible for on-site assistance in engineering, mining and management. Firefighters work in shifts around the clock for 365 days of the year. The fire brigade has a total of 8 vehicles: 5 fire pump trucks, a rapid intervention vehicle, a command vehicle and an ambulance. The main task of the fire brigade is to prevent fires. They are also responsible for measuring about 600 times a year in the concentration and aeration of various gases in the mining area to prevent workers in the mining area from the danger of suffocation and explosion.
