26m Spider Boom Lift for Chengdu Tianfu International Airport


Tailored for complex building structures, the customized 26m spider boom lift developed independently by Hubei Goman Heavy Industry has been officially delivered to Chengdu Tianfu International Airport. The equipment is now fully engaged in daily precision maintenance of the iconic “giant bird” terminal building.

As the largest civilian transport airport constructed during China’s 13th Five-Year Plan period, Chengdu Tianfu International Airport features a unique connected unit terminal structure and strict zero-downtime operational standards. With perfect balance of optimized working height, bionic all-terrain passability and full-electric silent performance, Goman’s 26m spider lift fully adapts to the intricate concourse environments, becoming a reliable guardian for the landmark aviation hub.

On-Site Challenges: Complex Maintenance Dilemmas of Modern Aviation Landmarks

Composed of multiple huge concourse units with a distinctive spreading “magic bird” architectural shape, Chengdu Tianfu International Airport boasts highly modern interior design. However, its unique structural characteristics bring three major maintenance challenges:

Complex Irregular Structures & Massive Maintenance Blind Zones

The terminal adopts extensive special-shaped steel structures and curved glass curtain walls. Traditional straight boom lifts fail to flexibly steer and operate in narrow connecting sections between concourse units, leaving numerous unreachable blind spots for daily inspection and renovation.

High-Pedestrian Flow & Zero-Disturbance Operation Requirements

As the core aviation hub of Southwest China, Tianfu Airport maintains dense passenger flow throughout the year. All maintenance work must not hinder pedestrian passage or generate noise and exhaust emissions that could affect passenger experience, requiring completely undetectable construction standards.

High-Precision Facility Maintenance Risks

The terminal ceiling is equipped with delicate daylighting panels, intelligent guidance screens and fire smoke exhaust systems. High-altitude maintenance demands extreme stability and precise micro-operation. Minor operational errors may cause costly damage to sophisticated terminal facilities.

Technical Breakthrough: 26m Golden Working Height for Airport Scenarios

Different from ultra-high industrial buildings, most maintenance heights of airport concourses are concentrated between 20m and 30m. Goman’s 26m spider boom lift is precisely developed for this golden height range, delivering targeted technical advantages:

26m Optimized Working Height Covers 95% of Terminal Maintenance Points

The precisely calculated 26m maximum working height easily reaches ceiling daylighting panels and steel structure joints without redundant equipment volume and cost waste. Even at full outreach, the platform maintains a stable rated load of 230kg, supporting two operators with heavy-duty electric tools simultaneously, fully complying with airport dual-person high-altitude safety regulations.

Bionic Folding Outriggers for Narrow Concourse Passage

Equipped with multi-section folding spider outriggers, the chassis retracts to only 0.8 meters in width. The bionic structural design enables flexible crawling and in-situ steering in narrow maintenance walkways and connecting corridors. Cooperated with non-marking rubber crawlers with ultra-low ground contact pressure, the equipment eliminates floor scratches and foundation settlement risks on high-grade airport floor tiles and epoxy surfaces.

Full-Electric Silent Operation & Intelligent Automatic Leveling

Fully equipped with a large-capacity lithium battery system, the equipment restricts operating noise below 55dB, equivalent to normal conversation volume, perfectly blending into the airport’s ambient background noise. To adapt to subtle ground slopes inside concourses, the intelligent automatic leveling system completes full outrigger leveling within 3 seconds, keeping the working basket completely horizontal at 26m height and eliminating operator vertigo for safer high-altitude operation.

Practical On-Site Value: Building Invisible Safety Barriers for Aviation Hubs

Since deployment at Chengdu Tianfu International Airport, the 26m spider lift has delivered outstanding performance during multiple night maintenance windows:

Dead-Zero Cleaning for Irregular Curved Facades

Benefiting from 360° continuous rotation and multi-angle telescopic booms, the equipment perfectly fits curved glass surfaces for comprehensive facade cleaning. It improves cleaning efficiency by 3 times compared with traditional hanging basket solutions. No passage closure is required during operation, causing zero impact on ground traffic and passenger flow.

Minute-Level Emergency Response for Zero-Downtime Repair

During an emergency repair of intelligent guidance screens on the T1 terminal ceiling, the equipment completed on-site deployment and 26m high-altitude positioning within only 12 minutes. Supported by instant lithium battery response capability, the maintenance team finished troubleshooting entirely during flight intervals, achieving true zero-downtime emergency maintenance.

High-Precision Steel Structure Anti-Corrosion Coating

The micro-motion control system enables ultra-precise platform adjustment during steel structure rust removal and painting. Workers can operate the basket with surgical accuracy, effectively preventing paint splashing and pollution on pedestrian passages below, realizing high-standard refined airport maintenance.

Customer Testimonial

The person in charge of the Terminal Management Department at Chengdu Tianfu International Airport commented after on-site acceptance:

“As a city business card of Chengdu, Tianfu Airport pursues maintenance standards of invisible operation, silent performance and rapid repair. Goman’s 26m spider lift is perfectly tailored for our concourse scenarios. Its excellent silent performance enables safe night maintenance without passenger disturbance, and the ultra-narrow chassis freely accesses the narrowest equipment mezzanines. In particular, the automatic leveling system guarantees absolute operational safety during curved daylighting panel cleaning. It is professional equipment that truly understands airport refined maintenance demands.”

Project Significance

The successful delivery and application of Goman’s 26m spider boom lift at Chengdu Tianfu International Airport verifies the equipment’s core advantages in large-span, high-density and zero-downtime scenarios. It also marks the increasingly important role of China’s high-end aerial work equipment in building green and intelligent airports.

In the future, Goman Heavy Industry will continue to deepen layout in the aviation infrastructure sector, providing smarter, greener and more efficient aerial work solutions to empower the high-quality development of China’s civil aviation industry.
