This chapter provides an overview of fixed vertical waste compactors, including their structure, operating principles, and overall design. It details the structural design of main components, the hydraulic and control systems, as well as relevant technical standards and performance testing. First, the chapter discusses the function, features, classification, application, and development trends of fixed vertical waste compactors. Second, it outlines the structure and working principles through waste transfer station process flows and covers the overall design. Third, the design of main components such as the moveable compactor, chute, waste container, steel structure, and hook-lift waste transportation truck is detailed. Fourth, it analyzes hydraulic system design requirements, system features, and hydraulic cylinder design. Fifth, the control system’s design requirements and features are described. Sixth, it summarizes technical standards, performance tests, and inspection protocols for fixed vertical waste compactors. Finally, the chapter discusses the basic requirements and configuration of main equipment for municipal solid waste transfer stations using fixed vertical compaction.
