Engineering Diploma

1. An Approach to Unit Delivery and Assessment Engineering Diploma Level 2 Unit 4 Producing Engineering Solutions Hydraulics Dump Truck

2. Student textbook: Edexcel Engineering level 2 higher diploma L2 U4 Producing engineering solutions: • Approach given here is formed by following the awarding bodies: • Learning outcomes • Assessment tasks Learning outcomes: • Health and safety – procedures, standards and risk assessment in engineering activities (LO.1) • Planning – plan an engineering product or service (LO.2) • Select materials, parts or components (LO.3) • Implementation - processes, tools and equipment to make product or carry out service (LO.4) • Inspection – apply to product or service (LO.5) It is not ‘design’ (this is covered by Unit 2 Investigating Engineering Design) Next >

3. Engineering theme: • LJ Hydraulics module contains an engineering solution for a trucktipping mechanism • It covers: • Planning • Installation • Inspection and testing • Understanding its processes • The Hydraulics module activities are used for acquiring knowledge and skills during unit delivery • The Hydraulic-based tipping system within the module is used for the assessment tasks as evidence of work Next >

4. Assessment Task 1 – Health & safety • Hazards (in general) – think about engineering processes and warning signs • Hydraulic system trainer and industrial equivalent (specific) – moving parts, compressed fluid, electricity and noise • Personal protective equipment (PPE) – to protect against these hazards • Staff conduct – training and supervision • Environment - tidiness, machinery guards, and environment markings and warnings • Risk assessment Next >

5. PowerPointpresentations Research tasks Simulation tasks Practical tasks Assessment Task 2 – Planning • Planning Process – create work instructions/job sheets • Plumbing • Mechanical links • Testing system • Hydraulics module provides the necessary knowledge and skills • Research hydraulic system components and processes: • Principles of hydraulics • Applications of hydraulics • Symbols and circuit diagrams • Actuators • Levers and movement • Valves and flow control • Speed control • Cylinder design A full list of module activities is provided Next >

6. Assessment Task 3 – Carrying out and inspection • Follow plan to build system • Prior to turn on - what visual checks? • Turn on – system checks • No load • Cylinder 1 loaded with weight • Evaluate engineering solution against plan • Evaluate engineering solution against simulation • Future maintenance scheduling Next >

7. Delivery and assessment approach: You are to setup a hydraulic tipping system for lifting and lowering the body section of a dump truck.The design team has provided their design for the system. As an engineering fitter, who is going to install and test the system, you will need to find out how the hydraulic controls and hydraulic cylinder work. You will also need to consider the health and safety aspects and ensure a risk assessment is undertaken. Careful planning is needed, ensuring work instructions are produced. • Explain the requirements of the assessed tasks to students • Assessment brief and tasks are provided • An example scheme of work is provided that enables students to acquire the knowledge and skills to complete the assessed tasks • The scheme of work states students should work through assignments 1 to 9 of the Hydraulics module Design from design team Next >

8. Delivery and assessment approach: • The scheme of work also refers to other sources: • Student textbook • Internet sites • Ideas for visits • LJ support documents • LJ Support documents include: • Health and safety – a range of worksheets • Risk assessment – examples and a template • Planning – example engineering production plan and test documents, along with a template Next >

9. Delivery and assessment approach: • The student is to collect evidence during the assessed tasks, by producing: • Risk assessment • Engineering operation plan • Components list • Circuit diagram • Test schedule • Evaluation report • System photographs Next >

10. Delivery and assessment approach: • The specification requires students to be aware of a range of technologies. The scheme of work includes the following: 1. ST260 Mechanisms module (Inevitably hydraulic systems provide power for mechanical systems): • Mechanical systems & motion • Levers • Cams • Friction 2. ST270 Pneumatics module (An alternative fluid power technology that reinforces concepts): • Valves • Pneumatic logic functions • Electro-pneumatics Next >

11. Delivery and assessment approach: Electronics is pervasive in modern engineering and it is required in the majority of engineering systems. Consider completing unit 5 before unit 4. If this is not practical, useful areas to cover include: 3. ST140 Basic Electricity module: • Switches • Safety and protection devices • Motors 4. ST450 Electronic Circuits module: • Automatic circuits • Alarms Next >

12. Extending the brief • An assessment brief and task sheets guide students in carrying out the three assessed tasks • Two options are provided to extend the brief to include a ‘make’ element in the assessed tasks • It provides students with an opportunity to use hand and/or machine tools • Students should be provided with a design that can be made using the centre’s facilities Some design options, that meet the requirements of the extension briefs, are provided in the scheme of work End >
