Crane Configuration Guide for Glass & Ceramic Plants
Crane configurations for the glass and ceramics industry must be tailored to the specific application — for glass furnace workshops, we recommend overhead cranes in the 10–32 t range (heat-resistant) with vacuum lifters; for tile production lines, heat-resistant cranes from 10–20 t (rated for 100–150°C) are the go-to choice; and for glass processing, a light-duty overhead crane (0.5–5 t) with a vacuum suction lifter is ideal. Kelude Heavy Industry's glass-industry cranes have been deployed in multiple float glass furnace maintenance projects.
Production environments in the glass and ceramics industry are defined by high temperatures (up to 70–100°C near glass furnaces) and heavy dust (from ceramic body and glass raw materials). From refractory brick replacement in glass furnaces to die changes on ceramic press lines, cranes must handle equipment maintenance and material handling in demanding thermal conditions. This guide breaks down crane configurations for three key scenarios: glass furnaces, ceramic tile lines, and glass processing.

Glass Furnace Crane — Equipment Maintenance in High-Temperature Environments
The glass furnace is the core of any glass production line — internal temperatures can reach 1600°C, with the furnace shell surface running at 70–100°C. Cranes here are primarily used for refractory brick replacement during furnace overhauls (typically every 5–10 years), regenerator chamber cleaning, and installation and maintenance of auxiliary equipment such as chargers:
- Recommended model: QD-type double-girder bridge crane (10–50t), Work Duty A4~A5, span 18–30m
- High-temperature protection: Class H insulated motors (rated for 180°C) + high-temperature cables (fluoroplastic insulation, rated ≥200°C), with stainless steel and ceramic fiber insulation heat shields fitted over motor housings
- Thermal radiation protection: Enclosed operator cab with double-pane heat-insulated glass + industrial air conditioner (cooling capacity ≥3kW), plus thermal insulation plates (≥30mm thick) on the operator cab floor
- Operation mode: Radio remote control as primary (operator stays on the ground, away from the high-temperature zone) with the cab as backup
- Reference price: QD-type 20t/24m with high-temperature package: approx. $44,500–$81,600
Ceramic Tile Production Line Crane — Mold Changes in Dusty Environments
Presses, drying kilns, glazing lines, and polishing machines on ceramic tile production lines require regular mold changes and maintenance. Ceramic dust (high SiO₂ content, with free SiO₂ concentrations of 5–30mg/m³) directly impacts both the protection requirements for electrical equipment and the respiratory health of operators:
- Recommended model: LD/LH-type bridge crane (5–20t), span 18–28m, Work Duty A4~A5
- Dustproof design: Electrical cabinets with IP54 protection + positive pressure dust covers (a slight positive pressure prevents dust ingress), TEFC motors, and periodic compressed-air cleaning
- Press area configuration: Given the large press tonnages (fully automatic hydraulic presses around 500–5000t) and mold weights of 5–20t, we recommend an LD-type 5–10t bridge crane or a BZD-type jib crane (3–5t) above each press
- Safe operation: Remote control operation — the operator handles mold changes from the side of the press, never underneath it
Glass Processing Workshop Crane — Light-Load, Clean Lifting
In glass processing workshops (cutting, edging, tempering, laminating, insulating glass), the workpieces are raw glass sheets and finished products — light but fragile. Cranes are used mainly for loading raw glass, warehousing finished glass, and packaging:
- Recommended model: LD-type single-girder bridge crane (2–10t) with vacuum lifter spreader (for glass sheet handling), or KBK-type underslung crane (0.5–2t)
- Glass lifting spreader: Vacuum lifter (suction cups 200–400mm diameter, vacuum ≥-0.06MPa, with pressure monitoring and pressure-holding on power failure), or C-type glass clamp (polyurethane gripping surfaces to prevent scratching)
- Dustproof standard: IP54 protection (glass edging generates glass dust with particle sizes <1100μm), fully enclosed motors
- Work duty: A4~A5 (processing workshops operate 8–12 hours per day)
Kelude Service Advantages for the Glass and Ceramic Industry

Our combination of Class H insulated motors, heat shields, and high-temperature cables is a mature, well-validated design.
- Vacuum lifting technology: Kelude's vacuum lifter spreaders handle glass sheets of virtually any specification — from 1m×2m to 3m×6m, in thicknesses from 2 to 25mm. Suction cup layouts are adjustable, with real-time vacuum pressure monitoring and pressure-holding on power failure.
- Dust protection system: Erosion of electrical equipment by ceramic and glass raw material dust is a persistent industry pain point. Kelude's positive pressure dust cover + IP54 + TEFC solution has been field-verified across multiple ceramic plants — reducing equipment failure rates by approximately 60%.
FAQ
Q: What type of crane is used for hoisting refractory bricks in a glass furnace workshop?
A: Individual refractory bricks for glass furnaces weigh 50–200 kg, but a single furnace overhaul can involve lifting and transporting 500–2,000 t in total. Recommended solution: install an overhead crane (10–32 t capacity) above the furnace, paired with a dedicated refractory brick lifting spreader (vacuum lifter or brick clamp capable of gripping 4–8 bricks per cycle). The crane must withstand surface temperatures from the furnace (roof surface can reach 80–120°C). Electrical equipment and the control cabinet should be located in the cooler zones at the furnace head or tail. A two-speed hoisting system is recommended (slow speed 1–2 m/min for precise positioning, fast speed 5–8 m/min for no-load travel). Kelude's glass-industry cranes have been used in maintenance work on multiple float glass furnace lines across China.
Q: What temperature rating does a crane need for the roller kiln area of a tile production line?
A: The roof surface of a tile roller kiln typically runs at 60–100°C (kiln interior reaches 1,150–1,250°C, while the outer surface of the insulation layer stays around 60–80°C). In the kiln inspection and maintenance section (where the roof is opened), thermal radiation can push temperatures to 150°C. Cranes in this area require: a thermal insulation layer on the underside of the main girder (aluminum silicate fiber felt with stainless steel cladding, 50–80 mm thick); heat-resistant motors and electrical equipment (Class H insulation, rated for 180°C); the control cabinet relocated away from the kiln zone or placed at the cooler head or tail end; and heat-resistant wire rope and lifting slings. Standard cranes are not suitable for use above glass furnaces. Kelude can supply custom heat-resistant cranes matched to your kiln's thermal parameters.
Q: How do you prevent scratching and breakage when lifting glass panels in a glass processing workshop?
A: In glass processing facilities (tempering, insulating, laminating, coating), the key to lifting glass panels is preventing scratches and breakage. Recommended solution: a vacuum suction lifter with NBR or silicone suction cups, a vacuum pump, and a holding tank that maintains vacuum for at least 30 minutes after power loss. A felt protective layer on the suction cup faces prevents surface scratching. Use a chain electric hoist (smooth, vibration-free operation with variable-frequency speed control from 0.5–4 m/min) on a KBK flexible rail or a light-duty overhead crane (capacity selected based on panel weight, typically 0.5–5 t). For coated glass, position suction cups away from sensitive coating areas; for insulating glass, never apply suction to a single pane. Kelude offers dedicated vacuum suction lifter systems for the glass industry.
Q: How does a dusty ceramic production environment affect overhead cranes?
A: Ceramic raw materials (clay, quartz, feldspar) and polishing dust create three major hazards for cranes: electrical component failure from dust accumulation and short circuits — addressed with positive pressure dust covers, IP54 or higher protection rating, and regular blow-down cleaning (recommended monthly); accelerated crane rail and wheel wear — ceramic dust is extremely hard (Mohs hardness 7) and, once inside the rail groove, significantly speeds up wheel wear, requiring sealed rail covers and grease-sealed lubrication; and motor overheating from blocked cooling vents — use TEFC totally enclosed motors with dust covers. Kelude ceramic-industry cranes come standard with positive pressure dust covers and IP54 electrical systems, reducing electrical faults in dusty environments by approximately 60%.
