Common Mistakes
Common errors to avoid in your coursework
- Skipping safety checks or using incorrect PPE.
- Not following the maintenance schedule precisely.
- Failing to document work or dispose of waste properly.
- Neglecting to fully isolate the plant or equipment before commencing maintenance, such as forgetting to verify zero energy state or missing lock-out steps, leading to serious safety risks.
- Rushing through documentation, resulting in missing signatures, incorrect dates, or incomplete descriptions of work carried out, which can invalidate maintenance records.
- Failing to confirm complete isolation of the tower crane, including locking off and tagging out energy sources, leading to unsafe maintenance conditions.
- Performing maintenance from memory rather than strictly following the written schedule, resulting in missed steps or incorrect servicing intervals.
- Overlooking the correct documentation of non-planned events (e.g., defects found during maintenance) and not reporting them through the proper escalation process.
- Improper segregation and disposal of waste materials, such as mixing oily rags with general waste or draining fluids without secondary containment.
- Failing to fully isolate and lock-out equipment before starting maintenance, leading to potential energisation or movement during work.
- Using generic or incorrect lubricants, cleaning agents, or parts instead of those specified by the equipment manufacturer, risking damage or voiding warranties.
- Overlooking the recording of minor defects or ‘near misses’ in maintenance logs, which are crucial for trend analysis and preventing major failures.
- Attempting maintenance tasks beyond the basic level without seeking specialist support, which can compromise safety and equipment integrity.
- Misconception: The crane operator is responsible for the installation. Correction: The installation is carried out by a dedicated team, supervised by a competent person, while the operator only operates the crane once it is installed and tested.
- Misconception: A tower crane can be installed on any flat surface. Correction: The ground must be properly prepared, with a concrete foundation designed to support the crane's loads and withstand wind forces.
- Misconception: Once installed, a tower crane does not need regular checks. Correction: Daily pre-use checks, weekly inspections, and thorough examinations are required by law to ensure ongoing safety.

How Students Lose Marks (Examiner Pitfalls)
Common mark loss traps and how to write 100% full-mark answers
Pitfall: Students often confuse the roles of the 'appointed person' and the 'crane supervisor' in the installation process, leading to incorrect answers in questions about responsibilities.
❌ Weak Answer (Loses Marks):The appointed person is the person who supervises the installation of the crane.
✅ 100% Model Answer (Full Marks):The appointed person is a competent individual named by the contractor to plan and oversee all lifting operations, including the installation and dismantling of the tower crane. They must ensure that the crane is installed according to the manufacturer's instructions and the lift plan, and that all risks are assessed. The crane supervisor, on the other hand, is responsible for the day-to-day supervision of the installation team, ensuring that the plan is followed and that safety measures are in place.
Examiner Tip: Always distinguish between planning (appointed person) and on-site supervision (crane supervisor). Use the terms 'plan' and 'supervise' to show clear understanding.
Pitfall: In calculations for crane stability, students often forget to include the weight of the counter-jib or the ballast, leading to incorrect overturning moment calculations.
❌ Weak Answer (Loses Marks):The overturning moment is the load multiplied by the distance from the mast.
✅ 100% Model Answer (Full Marks):The overturning moment is the sum of all moments tending to tip the crane over, calculated by multiplying each load (including the load, the jib, and the counterweight) by its horizontal distance from the crane's centre of rotation. For stability, the restoring moment (from counterweights and the crane's own weight) must exceed the overturning moment by a safety factor, typically 1.5 for wind and 1.4 for load, as per BS 7121.
Examiner Tip: Always list all forces and distances before calculating. Remember to include the weight of the crane's own components, not just the suspended load.
Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A tower crane has a maximum load capacity of 10 tonnes at a radius of 30 metres. If the counterweight is 20 tonnes and is positioned 10 metres from the mast centre, calculate the overturning moment when lifting a 6-tonne load at a radius of 25 metres. State whether the crane is stable, assuming the restoring moment from the counterweight is the only stabilising force and the safety factor required is 1.5.
- 1.Step 1: Identify the forces and distances. Load = 6 tonnes, distance from mast = 25 m. Counterweight = 20 tonnes, distance = 10 m.
- 2.Step 2: Calculate the overturning moment (OM) = load × distance = 6 × 25 = 150 tonne-metres.
- 3.Step 3: Calculate the restoring moment (RM) = counterweight × distance = 20 × 10 = 200 tonne-metres.
- 4.Step 4: Apply the safety factor: required RM = OM × 1.5 = 150 × 1.5 = 225 tonne-metres.
- 5.Step 5: Compare: actual RM (200) is less than required (225), so the crane is NOT stable.
Final Answer: The overturning moment is 150 tonne-metres. The restoring moment is 200 tonne-metres, but the required restoring moment for stability is 225 tonne-metres, so the crane is not stable.
Question: Describe the sequence of steps for installing a tower crane on a construction site, including the key safety checks at each stage.
- 1.Step 1: Prepare the foundation – ensure the concrete base has cured and meets the manufacturer's specification, and check the holding-down bolts are correctly positioned.
- 2.Step 2: Assemble the base section and mast – use a mobile crane to lift the first mast sections, securing them with bolts and checking verticality with a spirit level.
- 3.Step 3: Install the slewing unit and turntable – attach the slewing unit to the top of the mast, ensuring the slew ring is greased and the bolts are torqued to spec.
- 4.Step 4: Attach the jib and counter-jib – lift the jib into place, then the counter-jib, and install the counterweights as per the manual.
- 5.Step 5: Connect the electrical supply and test all functions – check the limit switches, emergency stops, and remote control operation.
- 6.Step 6: Conduct a thorough inspection and load test – perform a test lift with a known load to verify stability and safety systems, and record results.
Final Answer: The installation sequence involves foundation preparation, mast assembly, slewing unit installation, jib and counterweight attachment, electrical connection, and final testing, with safety checks at each stage.
