The Tower Crane Challenge: Precision at the Skyline
At Skyline Construction, a new skyscraper is being built, and expert crane operator Mark “Skyhook” Reynolds is in charge of lifting critical steel beams to the 40th floor before sunset. The deadline is tight, the winds are unpredictable, and every lift must be precise to ensure the structure’s integrity.
Mark operates a Liebherr 710 HC-L Tower Crane, which can lift 10 tons per load and swing at 0.5 minutes per lift cycle, including positioning and securing the beam. However, the challenge grows with every move:
🔹Required Lifts – A total of 80 steel beams must be placed.
🔹Wind Delays – Crosswinds above 20 mph will force a 3-minute pause between lifts.
🔹Safety Checks – Every 20 lifts require a 10-minute inspection to ensure stability.
🔹Shift Deadline – Mark has 6 hours to complete all lifts before work halts for the day.
The Questions:
- How long will it take to complete all 80 lifts without delays?
- How much time is lost if the wind forces 8 delays?
- Will Mark meet his deadline if two extra safety checks are required?
- If he must finish in 5.5 hours, how can he adjust his pace to succeed?
The skyscraper depends on Mark’s precision and timing. Can you calculate the right moves for him to complete the job on time?
