In Italy, commercial and public buildings built between the 1960s and 1980s are undergoing a wave of facade renovation. Old curtain walls need full replacement with energy-saving glass systems. Panels keep getting larger, while construction spaces in old towns become more limited. Traditional handling methods face huge challenges under narrow streets and tight building spacing.
A facade renovation contractor based in Italy’s Veneto Region encountered this problem. During each old curtain wall removal and replacement, moving and positioning insulated glass units over 500 kg was the most troublesome task. Streets are narrow, buildings stand close to each other, and large cranes cannot access the site. Traditional suction lifters have low efficiency and require multiple workers to operate.
Finally, they found a solution: YG-LD-600 glass panel lifting equipment. It features an 810 mm narrow chassis, 600 kg load capacity, 6 suction cups, 360° rotation plus 180° tilting — perfectly matching material handling demands for facade renovation projects in complex environments.
This article follows this customer’s real project and fully records the whole process from model selection to delivery. If you are looking for a glazing robot solution for European facade renovation projects, this case is worth referencing.

Why Did This Italian Glazing Firm Look for New Glass Vacuum Lifting Equipment?
Customer Profile:
Professional contractor for building facade renovation in Italy’s Veneto Region
Core business: full curtain wall replacement, energy-saving retrofit and facade upgrade for old buildings
Team size: around 25 staff, completing over 20 renovation projects per year
Clients: commercial buildings and public facilities in Venice, Padua, Verona, and other cities
Problems Encountered:
Alternating demolition and installation: Renovation requires removing old panels before fitting new ones. Demolition waste occupies site space, leaving limited room for handling equipment.
Restricted street and building gaps: Most Veneto old-town projects have narrow streets and closely spaced buildings. Large cranes cannot enter or unfold on site.
Upgraded glass specifications: New curtain walls after energy retrofit adopt triple-glazed insulated units. Single panel weight rises by 30–50% compared with old glass panels.
Tight schedule & limited road occupation time: Municipal permits for road works have strict time limits. Handling efficiency directly decides whether projects can finish on time.
Strict finished-product protection requirements: Buildings under renovation often remain in use (offices and shops stay open). No damage to surrounding facilities is allowed.
Customer Selection Requirements:
Minimum load capacity of 500 kg to handle large triple-glazed insulated panels for energy retrofits
Fully electric drive — construction inside occupied buildings, no noise or emission disturbance
360° rotation and 180° tilting for the suction cup frame, to meet installation needs at different angles
Chassis width no more than 900 mm, to pass narrow streets and gaps between buildings
Pressure hold function during power failure — prevent glass from falling in case of unexpected power loss
YG Glazing Robot: The Right Glass Panel Lifting Equipment For Their Job
Key Features Winning Recognition From The Italian Customer Electric Vacuum Suction System:
Independent control and separate vacuum valve for each suction cup
Remaining cups keep supporting the load if one cup loses pressure
Ø300 mm rubber suction cups deliver strong adhesion on smooth glass surfaces
Suitable for smooth surfaces including glass, ceramic and stone
Power-failure Safety System:
Maintenance-free batteries maintain vacuum pressure during unexpected power cuts
Audible and visual alarms alert operators immediately
Pressure holding time is long enough to safely lower the load
This directly satisfies the customer’s top safety requirement
360° Rotation + 180° Side Tilt:
Electric 180° flip of suction cup frame converts panels from horizontal to vertical
360° rotation precisely adjusts panel orientation for installation
On renovation sites, new panels need 90° flipping from flat state before fitting into frames after old curtain wall removal. This function greatly cuts manual work for panel flipping.
Compact Chassis:
Chassis width is only 810 mm
Can pass narrow streets and gaps between buildings
Moves flexibly in complex old-town environments in Veneto
Electric Lifting & Travel:
Fully electric operation; a single operator can complete handling and installation
Zero noise and zero emissions for indoor work
Meets environmental rules for construction in occupied buildings
Model Selection Process:
The customer initially considered two options:
Option
Model
Reason
Option A
YG-LD-500
500 kg load capacity fits most panels, evenly distributed 6 suction cups
Option B
YG-LD-600
600 kg load capacity provides larger safety margin, ideal for heavy triple-glazed panels after energy retrofit
YG-LD-600 was selected in the end for these reasons:
Single triple-glazed double-cavity insulated units after energy retrofit weigh nearly 550 kg
6 suction cups create a larger adhesion area than 4 cups, offering higher safety for big panels
600 kg load capacity leaves a safety buffer, avoiding continuous full-load operation
3,700 mm lifting height covers most floor heights
The customer also ordered extension bars to fit extra-large renovation glass panels.

Customer Feedback:
The suction stability of YG glass panel lifting equipment is satisfactory. No pressure loss or panel falling incidents occurred during the whole usage period.
The power-failure pressure hold function passed real-site tests. In one unexpected power outage, vacuum pressure lasted long enough for the operator to safely lower the load.
The 810 mm narrow chassis is its biggest advantage. Equipment from other brands cannot enter narrow streets in Veneto old towns.
Electric drive performs excellently in occupied buildings, totally quiet and emission-free without disturbing daily office work.
The 6-suction-cup setup provides sufficient safety redundancy when handling triple-glazed units.
Optional extension bars solve the suction coverage issue for extra-large renovation panels.
The customer has purchased a second YG-LD-500 for dedicated work with lighter panels.
