Why Use Crawler Cranes for Double Glazed Window Installations?
1. Unmatched Stability on Uneven Terrain
Unlike standard mobile cranes, crawler cranes use track systems instead of wheels, providing superior stability on:
Uneven construction sites
Soft or sandy ground (common in coastal Cape Town)
Confined urban spaces where outriggers can’t be fully extended 9.
2. High Lifting Capacity (Up to 8 Tons)
Double glazed windows—especially for skyscrapers and commercial buildings—can weigh 300kg to 1,200kg per panel. Crawler cranes handle this effortlessly, with models like the 3-ton to 8-ton spider cranes being ideal for precision lifts 9.
3. Precision Placement with Remote Control
Operators use wireless remote controls to:
Position windows with millimeter accuracy
Avoid collisions with building edges
Work safely from a distance (reducing on-site injuries) 9.
4. Glass Suction Cups Ensure Damage-Free Handling
Glass suction cups create a vacuum seal, eliminating:
✔ Scratches from manual handling
✔ Breakages due to uneven pressure
✔ Worker strain (reducing labor costs) 18.
How Glass Suction Cups Work with Crawler Cranes
Step-by-Step Process
Suction Cup Attachment – The crane operator aligns the vacuum pads on the glass surface.
Vacuum Activation – A 12V battery-powered pump creates negative pressure, securing the glass 11.
Lifting & Positioning – The crawler crane’s hydraulic arm lifts and maneuvers the window into place.
Controlled Release – The vacuum is slowly released, ensuring a smooth installation 8.
