The secret to its efficiency is the compaction cycle, which presses the waste against a steel plate located just behind the cab. This removes waste liquids and air, allowing the truck to make less trips to the city dump or local landfill. Rear loading trucks are designed to handle multiple types of garbage cans. There’s no need for the community to adopt a single waste bin design for all its residents.http://www.tongyatrailer.com/s....anitation-vehicle/sw
