Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately identifying the weight and centre of gravity of the load prior to slinging.
- Expect demonstration of correct hand signals or radio commands as defined in BS 7121 or company procedures.
- Require evidence of conducting pre-use checks on slings, shackles, and other lifting accessories, with defects reported.
- Look for consistent use of personal protective equipment and maintenance of exclusion zones during lifts.
- Assess the ability to coordinate a lift sequence effectively, confirming communication with the crane operator at each stage.
Assessment Guidance
Guidance for achieving higher grades
- 💡Build a comprehensive portfolio of evidence including photographs and witness testimonies showing you performing various slinging configurations and using correct signals.
- 💡During observations, verbalise your thought process to demonstrate awareness of risk assessment and compliance with the lift plan.
- 💡Revise key regulations and be prepared to reference specific clauses from LOLER, PUWER, and BS 7121 during professional discussions.
- 💡Practice hand signals regularly and consider video recording practice sessions to self-critique and improve clarity.
- 💡Always use correct terminology, such as 'slewing unit', 'jib', 'counter-jib', and 'anchorage', to demonstrate professional knowledge.
- 💡When answering questions about safety, refer to specific regulations (e.g., LOLER) and explain how they apply to the scenario.
- 💡For calculation questions, show all working and include units in every step to avoid losing marks for missing units.
Common Mistakes
Common errors to avoid in your coursework
- Using ambiguous or non-standard hand signals that can be misinterpreted by the crane operator.
- Failing to verify the safe working load of lifting accessories before attaching them to the load.
- Neglecting to check for overhead obstacles or ground conditions that could affect the lift path.
- Assuming the crane operator has understood a signal without receiving confirmation, leading to dangerous movements.
- Misconception: Tower cranes can be installed in any weather condition. Correction: Installation must be halted in high winds (typically above 20 m/s) or during lightning storms to ensure safety.
- Misconception: The crane operator is responsible for installation. Correction: Installation is a separate role requiring specific skills; the operator only uses the crane after it is certified safe.
- Misconception: Once installed, the crane does not need further checks. Correction: Regular inspections and maintenance are required by law, including daily pre-use checks and thorough examinations every 6-12 months.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A tower crane is to be erected on a construction site. The foundation is designed to withstand a maximum overturning moment of 5000 kNm. The crane's maximum load moment is 3000 kNm, and the counterweight moment is 1500 kNm. Calculate the total overturning moment and determine if the foundation is adequate.
- 1.Step 1: Identify the given values: maximum load moment = 3000 kNm, counterweight moment = 1500 kNm, foundation capacity = 5000 kNm.
- 2.Step 2: Calculate the total overturning moment by adding the load moment and counterweight moment: 3000 + 1500 = 4500 kNm.
- 3.Step 3: Compare the total overturning moment (4500 kNm) to the foundation capacity (5000 kNm). Since 4500 < 5000, the foundation is adequate.
Question: Describe the sequence of steps for installing a tower crane, including safety checks at each stage.
- 1.Step 1: Prepare the site: ensure the foundation is cured and meets specifications, and the area is clear of obstructions.
- 2.Step 2: Assemble the base section and anchor bolts, then use a mobile crane to lift the first mast sections into place.
- 3.Step 3: Continue adding mast sections, using climbing frames or self-climbing mechanisms, and ensure vertical alignment within tolerance.
- 4.Step 4: Install the slewing unit, jib, and counter-jib, then attach the counterweights.
- 5.Step 5: Connect electrical systems, test all safety devices (e.g., limit switches, anemometer), and conduct a load test before commissioning.
