The Chongqing Sanitation fleet has chosen the Allison 3000 series fully automatic transmission to improve its operational efficiency

The Allison 3000 series fully automatic transmission offers multiple advantages to the Chongqing Sanitation Fleet, including enhanced productivity, reduced total cost of ownership and improved driving comfort

As a leading designer and manufacturer of traditional and electrified vehicle drive solutions and the world's largest producer of fully automatic transmissions for medium and heavy commercial vehicles, Allison Transmission's 3000 series fully automatic transmissions have consistently provided unparalleled high performance and reliability for dedicated sanitation vehicles.

In order to improve the efficiency of urban sanitation operations and reduce the work intensity and pressure on sanitation vehicle drivers, the Yufengshan Municipal Sanitation Office of Yubei District, Chongqing, purchased 9 sanitation operation vehicles equipped with Allison fully automatic transmissions at the end of 2018, including 1 fog cannon vehicle, 3 sweeping and washing vehicles, and 5 water sprinklers.

The Yufengshan Municipal Sanitation Office is mainly responsible for sanitation operations in Yubei District, Chongqing. In this area, there are elevated roads, expressways, five interchanges, three tunnels, and an area close to the airport. In summer in Chongqing, the weather is hot and the terrain is complex, which places high demands on the skills of the drivers in the fleet and the performance of the vehicles.

To efficiently clean the road surface, the speed of sanitation operation vehicles usually does not exceed 35 kilometers per hour, and they start and stop frequently. When using a manual transmission, it is necessary to constantly shift gears to maintain a low vehicle speed, which in turn affects the vehicle's flushing, sweeping, garbage suction and spraying pressure. When starting fully loaded, manual gear shifting will accelerate fuel consumption and also affect the driver's concentration on driving the vehicle safely and efficiently.

Under any road conditions, Allison Continuous Power Technology™ enables the fully automatic transmission to smoothly and simply deliver the engine power to the wheels without interruption. The driver can place both hands on the steering wheel and focus on controlling the vehicle and performing cleaning tasks. The Allison fully automatic transmission is easy to operate and achieves perfect coordination between driving mode and working mode.

The three sweeping and washing vehicles of Yufengshan Municipal Sanitation Office are based on the Dongfeng Tianjin 4x 2 chassis, equipped with a Dongfeng Cummins ISDE 210-50 diesel engine with a power of 155 kW and a torque of 800 Nm. They are also equipped with an Allison 3000 fully automatic transmission featuring six forward gears and a power take-off interface. The rated total weight of this vehicle is 16 tons, the capacity of the garbage bin is 9 cubic meters, and the capacity of the water tank is 7 cubic meters.

The drivers of our fleet drive the sanitation operation vehicles for an average of 8 hours a day, covering about 100 kilometers, mainly on urban expressways, with some uphill and downhill sections, curves and other areas. "Since the adoption of models equipped with Allison's fully automatic transmission two and a half years ago, drivers have reported that vehicle operation has become simpler and more convenient, allowing them to focus on the road and the use of equipment," said Tian Wenjun, the team leader. "For drivers, the outstanding performance of Allison's fully automatic transmission makes their work easier, reduces labor intensity and greatly improves work efficiency." "

Allison transmission achieves precise vehicle control and maneuverability because it uses a hydraulic torque converter instead of the traditional dry clutch, smoothly doubling the engine torque during vehicle start-up and acceleration. The Allison transmission control module can customize the working time and mode of the power take-off. The driver only needs to press a button to activate or deactivate the power take-off, thus better focusing on the driving task.

Veteran driver Huang Qinian of the fleet, when talking about his over two years of driving a sweeper equipped with an Allison transmission, couldn't stop praising: "The biggest challenge of driving a sanitation vehicle on a busy expressway is that you have to balance focusing on other vehicles on the road and operating your own vehicle." I used to drive all manual transmission vehicles. After switching to an automatic one, I'm not afraid of traffic jams. Even when fully loaded when starting uphill, I'm not worried about the car rolling backward. The Allison transmission is easy to operate, allowing me to drive and clean at the same time."

Allison automatic transmissions are specifically designed for demanding applications. As there is no need to replace the clutch, the maintenance cost is reduced through the Allison pre-diagnosis function. If the service life of the engine oil and filter elements can be predicted, there is no need to schedule daily vehicle maintenance, thereby reducing downtime and lowering maintenance costs. It only requires regular oil and filter changes, thereby extending the vehicle's driving time and enhancing operational reliability.
