Construction Plant Fitting study plan
Construction Plant Fitting · Give each week a clear focus.
8 weeks · About 7 hours per week
Construction plant fitting
Identify and label the main assemblies of hydraulic excavators, backhoes, dozers, and wheel loaders from memory, writing each component's function in one sentence
Explain the operating principle of four-stroke diesel engines and list the function of the fuel, lubrication, cooling, and air-intake systems
Describe the purpose of the hydraulic system on construction plant and name the reservoir, pump, control valve, actuator, and filter in circuit order
List the five most common causes of hydraulic leakage and state the inspection point that reveals each one
Your checkpoint
A hand-drawn or digital component map for three machine types with every part named and a one-line function, plus a 20-item self-quiz scored at 80% or higher
Construction plant fitting
Read and interpret hydraulic and pneumatic circuit symbols to ISO 1219 conventions, translating a simple circuit into a written sequence of operations
Explain pressure, flow, and actuator force relationships and calculate force from pressure and cylinder area for three worked examples
Describe how relief, directional, and flow-control valves behave and state the symptom of a mis-set relief valve
Identify the safety precautions for isolating and depressurizing a hydraulic circuit before maintenance
Your checkpoint
A written walkthrough of two circuits (one hydraulic, one pneumatic) with three solved force/flow calculations and a one-page lockout and depressurization checklist
Construction plant fitting
Explain the function and adjustment of the major systems on a diesel engine, including injection timing, valve clearance, and governor action
Diagnose five given fault symptoms (hard starting, black exhaust, overheating, low oil pressure, excessive vibration) and rank likely causes for each
Describe the correct procedure for servicing filters, belts, and coolant on plant equipment without introducing contamination
State the torque and measurement checks that must be recorded during a routine engine service
Your checkpoint
A fault-diagnosis table covering ten symptoms with at least three ranked causes and a confirming test for each, reviewed against your notes
Construction plant fitting
Describe the construction and failure modes of wire rope, chains, and lifting accessories, and state rejection criteria for each
Explain the inspection requirements for slings, shackles, and hooks, including wear limits and marking checks
Outline the daily and periodic inspection routine for an excavator or crane before work starts
Identify the PPE and exclusion-zone controls required for lifting and rigging operations
Your checkpoint
A pre-use inspection checklist for one machine plus a rejection-criteria card for four lifting accessories, both self-tested by recall without notes
Milestones
Week 4: Score 80% or higher on a closed-book 40-question mixed test covering machine systems, hydraulics, engines, and lifting gear, and log every missed item with the reason it was missed
