Abstract

This dissertation details the design of a new steering system that improves manoeuvra-bility of the RUSSELL Multi-Wheel Feed Chute Transporter.

Feed chute transporters are used in the grinding mill industry to extract, transport andreplace grinding mill feed chutes. Steering is currently achieved through a hydraulic mechanical linkage system. This design creates limitations in the achievable steer angles and thus manoeuvrability, leading to inefficiencies while operating the machine around site.

Russell Mineral Equipment have highlighted the steering system as an aspect that would benefit from further development. A defined project scope and concept evaluation led to the proposal that independent steering through slew drives at each wheel will meet the functional requirements. This concept was developed and then full detailed design completed. Finite Element Analysis conducted on each basedrive group ensured that the design was suitable for all loading conditions. All interfacing stages were then updated to suit. The new steering design has a new hydraulic system, with detailed schematics illustrating the layout across the machine.

The framework for the steering control strategy provides the necessary turning angle required at each wheel to achieve a certain turning radius at the selected steering mode. The operator will control steering and drive using a joystick via CANbus communication.

This project has resulted in the design of an independent steering system for the Multi-Wheel Feed Chute Transporter. Slew, crab, front wheel and rear wheel steer modes are now achievable which significantly improves manoeuvrability and steering capabilities. This design can be implemented onto future production RME Feed Chute Transporters that have the requirement of improved steering.
