Design Competence
Resource Technologies designs machines to the highest standards in accordance with relevant ISO, DIN, BS, FEM, AS and SANS specifications, supplemented by specialist knowledge gained through experience and research over many years. The design engineers in various disciplines are well qualified and professionally registered with ECSA and other industry bodies. Machines are designed with long term performance and durability in mind, rather than low initial purchase price.

The company has specifically built up the knowledge and personnel locally to execute the full product design cycle from its office in Johannesburg:
• Requirement definition and feasibility studies
• Conceptual design
• Basic Engineering
• Electrical Engineering
• Detail Design
• Construction support
• Commissioning support
• Support to Service Department throughout the life cycle of the machine

Apart from facilitating direct interaction between clients and the designers to ensure that the design best suits the application, having a locally based design team has the further advantage that this expertise is easily accessible during the construction and operation of the machines to address any issues that require technical input.

The extensive local design competence is backed up by the global TKF engineering expertise. Resource Technologies has access to the specialist knowledge of engineers in other thyssenkrupp branches, and likewise the other branches has access to our expertise - we are deemed to be the global centre of excellence for drum reclaimers by thyssenkrupp AG. This global technical network allows access to additional engineering resources when local demand requires this.
Requirement Definition and Feasibility Studies

Resource Technologies can assist clients to configure bulk materials handling plants optimally within the parameters determined by the client.

This service includes the selection and sizing of machines, conceptual plant layout, conveyor design, price estimates and comparisons between different layout / machine type options. Operating and maintenance cost estimates can also be provided, to assist the client in undertaking financial feasibility analyses.
Conceptual Design

Because of the strong local design capability bulk handling equipment can be designed around a client’s specific requirements from a clean sheet of paper. Such a concept would be developed in conjunction with the client, and would result in a conceptual layout of the required plant or individual machines – with estimated power requirements and bill of materials. In some cases existing designs can be used, and the interfaces of such equipment with the client’s plant would be shown.
Basic Engineering

During this phase of the project our engineers design the mechanical components, structures and electrical control and instrumentation of the machine, developing the concept design to a detailed design.

As a first step the various mechanical systems are designed in order to arrive at the loads imposed on the structure, as well as the electrical and hydraulic drive parameters. Detailed technical specifications for the mechanical equipment are compiled to reflect these requirements.

The structure is analysed for all anticipated load cases in accordance with relevant specifications, e.g. ISO 5049, FEM Section II and AS4324/1. A combination of advanced Finite Element (FE) analysis and manual calculations in accordance with the codes is used at this stage to accurately determine the loads and stresses in geometrically complicated structures. The output from the FE analysis is in turn used in manual calculations to verify the compliance of buckling resistance of plates, members, and overall structures, connection detail and stability against overturning with the codes.

Any changes required to the conceptual design based on the mechanical and structural analyses are incorporated and the analyses updated as required.
Electrical Engineering
The electrical, control and instrumentation requirements are developed and documented in close collaboration with all the disciplines involved in the plant design. The EC&I requirements are formulated and presented by way of functional descriptions, specifications, and drawings. The electrical department is involved in the project from tender stage to final hand-over.
Detail Design

During this phase of design the details as determined during the basic design is reflected on detail drawings from which fabricators can make the various assemblies. All drawings are done in CAD to ensure accuracy. Very experienced machine draughtsmen are used to produce drawings of the highest quality.

Integral to the detailing is both a draughting checking process, as well as engineering checks to verify that the detail drawings reflect the design as done by the engineers.

In parallel with this an independent design verification is carried out, either in-house or using a 3rd party.
Construction Support

Because the design engineers are based locally they are also able to support the fabrication phase of the machines, to handle any queries regarding details of the design, welding, fabrication practices or materials.

This same support is available to streamline assembly of the machines in conjunction with the site team, and to verify that machines are assembled to the satisfaction of the design engineers.
Commissioning Support

The design engineers also assist with the commissioning of the machines in conjunction with the commissioning team – to ensure the functionality on site is implemented as foreseen in the design.
Support to Service Department

The Service Department assists clients with major maintenance, upgrades and repairs of thyssenkrupp Materials Handling machines where required. The Service Department again has direct access to the design engineers to analyse upgrades and address any problems that may arise in the maintenance or operation of machines. This also provides valuable feedback to the designers on the long term performance of machines.
