The Indian company's state-of-the-art steel plant produces stainless steel products for industrial and infrastructural applications, as well as everyday consumer goods. When an additional vehicle was needed, the company management opted for the KAMAG model 2803-170 SPC with its compact U-frame design. The U-frame design of the SPC reduces loading and dropping off times, and thanks to the low loading height, the shortest route can be selected even with low clearance under warehouse doorways or pipe bridges. The KAMAG SPC (Slag Pot Carrier) is powered by a Caterpillar C15 diesel engine with 403 kW (540 hp) operating at 2,100 rpm. Combined with the robust, fully automatic Allison 4000 SP transmission and the DGS VG2600 transfer gearbox, the compact driveline delivers excellent traction during vehicle start-up and smooth power delivery without any interruption. Despite of its enormous dimensions of 12.35 meters in length, 7.62 meters in width, 5.25 meters in height, and an empty weight of 96.5 tons (266.5 tons fully loaded), the SPC is exceptionally agile and easy to maneuver. The fully automatic transmission shifts precisely and reduces the strain on the driver — a significant advantage during transport and tipping operations at the landfill’s cooling basin.

24/7 operational readiness with robust technology

The steel industry requires machines with solid engine and transmission technology that are designed for years of continuous, round-the-clock operation. The KAMAG SPC was specially designed for such conditions. Its robust construction, long maintenance intervals and the innovative KAMAG Connect remote maintenance option ensure seamless operation. The driver's cab is sealed against gas and dust, air-conditioned, and equipped with state-of-the-art technology, including a multifunctional display and comprehensive surround camera technology, that helps the driver to maneuver with precision and to control the unloading processes safely.

Increased productivity, reduced costs

Thanks to the robust Allison fully automatic transmission, maintenance requirements are minimized. Using a torque converter instead of a conventional clutch reduces wear parts and lowers maintenance and repair costs. This results in longer operating times and less downtime, which in turn increases overall productivity.

The Indian steel mill already operates several SPCs from TII KAMAG and was looking for a slag pot carrier that is just as robust, reliable and easy to operate as the existing models, but at the same time offered a significantly higher payload. The SPC 2803-170 with the Allison transmission has a 170-ton-payload, meeting these requirements exactly and contributing to the customer's steel production being even more efficient.

Michael Birzele, team leader of the Business Unit Industry and Special Projects at KAMAG, confirms: “Our SPC models have been equipped with Allison transmissions since 2013 and are in operation around the world. This configuration offers the most compact drivetrain. It delivers high torque, unmatched power and excellent traction. Furthermore, the fully automatic transmissions are extremely robust and require minimal maintenance. We have never had any problems with these transmissions, and we install them in all our SPC models with U-frame construction, from the 100-ton SPC to the 140-ton and up to the SPC with 170 tons payload”.

Michael Birzele adds: “Thanks to the fully automatic transmission, our SPCs are very easy to operate, almost like a car. We hear time and again from our customers' drivers that they feel really safe with this technology, despite the large bucket full of red-hot slag behind them, and that they enjoy driving.”

The solution was the introduction of four new Rosenbauer Panther 8x8 fire truck s, each equipped with Allison 4800R fully automatic transmissions. These transmissions were chosen for several key reasons:

• Superior Acceleration: The vehicles can accelerate from 0 to 50 mph in about 20 seconds, thanks to the combined output of 1,430 horsepower from two Volvo D16 Euro 6 engines and the Continuous Power Technology and Torque Converter from Allison fully automatics.
• Continuous Traction: The Allison transmissions provide continuous traction, allowing the 52-tonne trucks to be maneuvered swiftly and with precision, even in challenging conditions. 
• Immediate Pump Operation: Because of the Power Take Off (PTO) integrated in the fully automatic transmission, the main operator can start the pump and roll immediately, providing more time to respond effectively to emergencies. 
• Advanced Firefighting Equipment: The Panther 8x8s are configured with rapid attack hose reels and self-protection nozzles, enhancing the team's ability to handle a wide range of emergencies with precision and efficiency.
• Minimal Maintenance: The robust design and fully hydraulic technology of the Allison transmissions ensures minimal maintenance, reducing downtime and operational costs. The integrated hydraulic retarder and power take-off have also proven to be very low maintenance.

The timeline for the introduction of these vehicles was from late 2023 to early 2024, ensuring a smooth transition and immediate operational benefits.

Transmission Technology for the Highest Demands Allison 4000 Specialty Series (SP) transmissions are designed for the toughest heavy-duty applications. They are built for engines ranging up to 597 kW and feature six or seven forward gears, depending on the model. The transmissions’ Continuous Power Technology™ ensures uninterrupted power delivery and delivers more power to the wheels via the torque converter than other transmission technologies. This results in a smooth, jerk-free gear change without any interruption in traction as well as excellent vehicle control - even with a total vehicle weight of almost 267 tons. In addition, Allison transmissions feature an intelligent shift strategy: they automatically adjust the shift points in real time to the current load in order to achieve an ideal balance between performance and fuel consumption. When the slag bucket is empty, the transmission shifts at lower engine speeds, thus reducing fuel consumption, while when fully loaded, higher engine speeds provide more traction and power. The directly mounted VG2600 transfer gearbox is positioned behind the drive axle of the tractor unit and, via its offset, drives the axle from the rear using the shortest distance. The VG2600 is supplied by DGS Diesel- und Getriebeservice GmbH in Mainz, the German general distributor for Allison, which also played a key role in integrating the Allison transmission with offset gearbox into the KAMAG slag pot carrier.

The KAMAG SPC slag pot carrier with Allison fully automatic transmission is a tailor-made, precisely engineered solution for the extreme demands of slag transport. Combining a robust vehicle design with powerful drive technology, it sets standards in terms of driving performance, efficiency and driving comfort. The long-standing partnership between TII KAMAG, Allison Transmission and DGS has set new standards in heavy-duty transport for the steel industry. TII KAMAG has been using Allison transmissions for many years, both in U-frame slag pot carriers and in industrial lift carriers.

Background information on slag Slag is produced during the metallurgical manufacturing and processing of metals. It is separated from the metal during smelting and then “floats” on top of the molten metal due to its low density. There it is removed and transported in a liquid state at temperatures of around 1,500 degrees Celsius in slag pot carriers to the cooling ponds. Afterwards, it is either used as a secondary raw material in the construction industry, for example in road construction or cement production, or it is disposed of in landfills.
