Inside the Construction Hoist: Tower Crane Access & Lift Mechanism

This video provides an in-depth look at the construction hoist system integrated into a Comansa tower crane. Learn how hoist mechanisms—drums, wire ropes, rack-and-pinion drives, and the personnel/material cage—work together to safely transport workers and equipment up the mast. We highlight key components like the hoist drum, gearbox, braking system, and mast sections, and explain how the hoist interfaces with the trolley and jib for seamless vertical movement. Ideal for crane operators, site engineers, and construction professionals.

What you’ll discover:
• 📦 The design & structure of the hoist cage – materials, safety features, and capacity
• ⚙️ Rack-and-pinion or gear drive mechanism powering smooth ascent/descent
• 🧲 Brake and safety systems preventing uncontrolled drops or overspeed
• 🪜 Integration with tower crane mast sections for dependable vertical travel
• 🧰 Dual function: moving both personnel and materials efficiently
• 📏 Tech specs: typical loads, speeds, and compliance standards (e.g. CE-certified systems)

Why it’s important:
Understanding hoist systems not only aids in safe crane operation and site logistics—it also deepens your appreciation of vertical transport engineering on construction sites.
