Fork-Borne Adapter for Multi-Container Waste Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial waste commodity collection trucks typically require multiple specialized vehicles to handle different types of containers (front, side, and rear loading), leading to inefficiencies and safety concerns due to the need for operators to frequently exit the cab for manual container handling.
Innovation Solution
An adapter system for front-loading trucks that allows for the collection of all three types of containers using automated methods, featuring an intermediate container, lifting mechanism, and adaptable engagement mechanisms for trunnion-equipped and hook-equipped containers, along with optional gripping arms for residential containers, enabling a single truck to perform tasks of multiple conventional trucks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single front-loading truck is used to collect all container types, then fleet size and operational costs are reduced, but the device complexity increases due to the need for adapter systems
Solution Approach 1:
The adapter system is designed with multiple engagement mechanisms that can attach to different container types (front-loading, side-loading, and rear-loading containers) using the same front-loading truck. The adapter includes a trunnion engagement mechanism for rear-loading containers, a hook engagement mechanism for side-loading containers, and direct fork engagement for front-loading containers, allowing one truck to perform multiple collection functions
Solution Approach 2:
The adapter system acts as an intermediary device between the front-loading truck forks and various container types. The adapter includes an intermediate container that can be loaded by the truck forks and then manually emptied into the collection body, bridging the compatibility gap between front-loading trucks and non-front-loading containers
2Adaptability or versatility
If operators manually handle different container types, then collection flexibility is maintained, but safety risks increase due to frequent cab exits
Solution Approach 1:
The adapter system enables automated collection of various container types through the truck's existing hydraulic system and controls. The engagement mechanisms automatically attach to and secure different container types (trunnion bars, hooks) without operator intervention, and the intermediate container automatically positions for loading, allowing operators to remain in the cab while maintaining versatility
3Reliability
If multiple specialized trucks are used for different container types, then operational safety is improved, but operational costs and downtime increase
Solution Approach 1:
The adapter system allows a single front-loading truck to collect all three major container types (front-loading, side-loading, and rear-loading), eliminating the need for multiple specialized trucks. This reduces fleet size, operational costs, and maintenance downtime while maintaining safety through automated engagement mechanisms that securely attach to each container type

AI summary
An adapter for front forks of a front loading commodity collection truck allows the truck to collect from rear load and side load style containers. An intermediate container is carried on the forks of the truck. An engagement apparatus is mounted on the intermediate container and is laterally extendible to engage the commercial container at curbside and draw the container to the intermediate container. The engagement apparatus will lift the commercial container and tip it over the intermediate container. Controls in the cab of the truck control operation of the adapter. The adapter can be removed easily from the forks when a front loading refuse container is encountered.
