The company responsible for refuse collection in half of the city of Sao Paulo, and one of the pioneers in the use of Allison fully automatic transmissions in the country, has almost its entire fleet equipped with the 3000 Series™ models.
SÃO PAULO, Brazil – March 2021- A Logística Ambiental de São Paulo S.A. (Loga) is a company that specializes in the collection, transportation, treatment and final disposal of household and healthcare refuse generated in the Northwest Area of the Municipality of São Paulo. With more than two thousand employees, it serves the region comprising of the Center, North and West Zones of the city, where there are more than 800 neighborhoods and 13 Regional City Administrations. Loga accounts for the collection of six thousand tons of refuse from 1.7 million households, hospitals, health practices, and the like, serving seven million residents, including the floating population in the region.
Loga has approximately 350 vehicles in their fleet, 150 of which are compactors for residential refuse collection, including special trucks for healthcare waste collection and mechanized equipment for surface and underground collection. In its most recent vehicle renovation in the second quarter of 2020, the company purchased 68 new refuse compactors. With the incorporation of the new trucks, the number of vehicles equipped with the Allison 3000 Series™ has reached 135, meaning, 90 percent of the refuse compactor fleet has fully automatic transmissions.
“We first introduced automatic transmissions to our fleet in 2009, and since then, at every vehicle renewal, we replace the manual transmission trucks with automatic ones,” said Yuri Oblitas, Loga's maintenance supervisor. "This preference reflects the several advantages of automatic models, among them, greater productivity, low maintenance costs, comfort for drivers, and the transmissions' safety and guarantee."
Loga links the increased productivity of automatic trucks with several factors. Among them, the greater availability of drivers who don’t experience fatigue so quickly. The automatic shifting also lessens the mechanical problems involving engines and clutches. The company also highlights a significant cost reduction with the replacement of clutch parts and with labor, since it needs fewer mechanics to maintain the trucks.
“Using manual transmissions, parts and mechanics are frequently necessary for the change of clutch system every 50,000 or 60,000 kilometers, which is not the case with automatic transmissions, resulting in greater availability of the vehicle for operation. Our level of satisfaction with Allison automatic transmissions can be more precisely explained by the fact that they are present in all of our fleet renewals, in other words, we buy them increasingly more,” said Oblitas.
One of the factors that characterize the efficiency of Allison transmissions is the presence of the torque converter, which multiplies the force generated by the engine and transfers it smoothly to the gearbox. This hydraulic coupling component adds a controlled damping effect, with smooth shifting. With this, the trucks have greater starting capacity, faster acceleration, better traction, and provide greater steering control. Allison's fully automatic transmissions allow for greater productivity, better maneuverability at low speeds, powertrain protection, low maintenance costs and greater ease for the driver.
