Lesson 1Ground and foundation checks: crane base, pad conditions, temporary roadways, surface bearing capacity and ground water/drainage issuesIn this lesson, you will discover how to check crane bases, foundations, and paths, confirm if the ground can hold the weight, spot weak areas, holes, or washing away, and look at water flow or underground water that might make things unstable during work.
Looking at soil and weight dataChecking crane base, ties, and padsLooking at temp roads and pathsFinding soft soil, holes, and washingChecking water flow and underground effectsWriting and telling about ground problemsLesson 2Communication equipment checks: radio testing, battery management, spare handhelds, signage and backup hand signal protocolsYou will find out how to check and test talking tools like radios, batteries, chargers, extra units, and signs, and set up clear backup hand signals to keep things under control if main systems stop working during lifts in busy sites.
