Abstract
A delivery chute for use on a concrete mixer truck has automated systems to allow for repositioning and reconfiguration without requiring an operator to manipulate components. The chute is configured to have multiple segments that can be folded/nested with one another for transport and can be positioned in an extended configuration thereby forming a continuous delivery surface for purposes of delivering concrete to a desired location. Powered mechanisms are used to reposition these segments, thus eliminating the need for operators to handle chute segments at all. A control system is provided to coordinate operation of components so proper sequences are followed during folding, unfolding, raising, lowering and swinging operations. An operator can control each of these operations using a remote control, having single buttons to carry out specific operations.
