Mobile Spider Crane Case Study: Shopping Mall Glass Installation
Project Challenge: Complex Indoor Atrium Glass Replacement
A commercial contractor was tasked with replacing and installing large glass panels for a multi-story atrium in an active shopping mall. The site presented several critical logistics and safety hurdles:
- Strict Access & Floor Load Limits: The only entry point was a narrow service doorway measuring just 1.2 meters wide. Additionally, the indoor floor consisted of delicate marble tile with strict ground-bearing pressure limits, completely ruling out standard truck cranes or heavy equipment.
- Confined Indoor Space: Scaffolding and interior structural columns left minimal clearance. Manually moving glass panels weighing over 300 kg across multiple levels was both extremely slow and carried high risks of glass breakage and personal injury.
The Solution: Precision Lifting with the YG-5 Mini Spider Crane
To solve these constraints, the contractor deployed the YG-5 Tracked Mini Spider Crane equipped with an optional vacuum glass lifter and fly jib.
- Ultra-Compact Access: With a transport width of just 1.5 meters and a low-profile crawler chassis, the YG-5 easily navigated through narrow service doors directly to the atrium site.
- Multi-Attachment Precision: The integrated vacuum glass lifter safely secured 300+ kg glass panels without manual rigging, while the fly jib extension allowed the crane to maneuver past tight structural columns smoothly.
- Surface Protection & 360° Control: Rubber crawlers protected the sensitive marble floor, and the operator used a wireless remote control to position panels into curtain-wall frames with millimeter accuracy.
Key Outcomes & ROI
- Repeat Business: Satisfied with the operational performance, the contractor subsequently purchased additional YG spider crane units to expand their commercial curtain wall and building maintenance services.on work.
- 70% Time Savings: The entire high-altitude glass installation took just 3 days to complete, down from the originally estimated 10-day manual timeframe.
- 60% Labor Reduction: The installation crew was reduced from 8 workers down to 3 (1 remote operator and 2 alignment technicians), significantly lowering labor costs.
- Zero Safety Accidents & Damage: Wireless remote operation eliminated dangerous manual lifting, achieving zero site injuries and zero glass breakage throughout the project.
