Overhead Crane

A: A wide range of overhead crane classifications are widely used on site, covering single girder overhead cranes, double girder overhead cranes, European overhead cranes, top-running overhead cranes as well as under-slung overhead cranes. Users can finish proper selection according to actual demands. Key reference factors cover lifting capacity ranging from 1 ton to more than 500 tons, practical lifting height and working span, daily service frequency and working duty class, internal headroom space inside the plant, actual operating environment including normal space, dangerous area and high temperature site, together with actual budget arrangement.   

Single girder overhead cranes work perfectly for light duty and medium duty working scenes with insufficient headroom space. When it comes to heavy duty working occasions that need large load capacity and long span distance, double girder overhead cranes can offer more stable running state and better overall lifting working performance.

A: Single girder overhead cranes feature one bridge beam and are ideal for capacities up to 20 tons with shorter spans, offering:  

 - Lower headroom requirements  

 - Reduced cost  

 - Easier installation   

Double girder overhead cranes have two bridge beams, supporting capacities from 5 tons to over 500 tons with longer spans, providing:  

 - Better hook coverage  

 - Higher lifting heights  

 - Enhanced stability for heavy-duty operations   

The choice depends on your specific lifting requirements, facility constraints, and long-term operational needs.

A: The minimum headroom required varies by crane type:  

 - Standard single girder overhead cranes: 3-5 meters of clear height from runway beam to floor  

 - Double girder bridge cranes: 4-6 meters depending on capacity and lifting height  

 - Low-headroom or under-slung designs: as low as 2.5-3 meters The above are approximate reference data.  

 The exact height will depend on the assessment of the on-site situation and requires a specially designed and customized solution.

A: Choose a gantry crane when:  

 - Your facility lacks adequate building structure to support overhead crane runway beams  

 - You need outdoor lifting capabilities  - Mobility is required across different work areas  

 - You want to avoid building modifications   

Overhead bridge cranes are preferable for:  

 - Indoor applications with existing support structures  

 - Maximizing floor space utilization  

 - Requiring higher lifting capacities and duty cycles  

 - Frequent, repetitive lifting operations   

Gantry cranes offer flexibility and lower installation costs, while overhead cranes provide better space efficiency and higher performance for dedicated production lines.

A: Kino Cranes produces overhead cranes that follow mainstream international industry norms: 

- FEM standards covering crane design and working classification 

- CE approval to meet market entry rules within European Union regions 

- ISO 9001:2015 certification for standardized quality management 

- EAC qualification suitable for sales in Eurasian Economic Union areas 

- CMAA specifications fitting actual usage demands in North America 

We have over 18 years of production and export experience, with our products shipped to more than 100 nations. All our lifting equipment can satisfy general global export rules as well as local official regulations, covering markets in the Middle East, Southeast Asia, South America, Africa and Europe.

A: We offer crane duty classes ranging from light duty to heavy-duty applications: 

- FEM 1m / CMAA Class A (Service Class 1): Light duty, infrequent use at low loads - maintenance workshops 

- FEM 2m / CMAA Class B (Service Class 2): Light to medium duty - assembly lines, warehouses 

- FEM 3m / CMAA Class C (Service Class 3): Medium duty - machine shops, manufacturing 

- FEM 4m / CMAA Class D (Service Class 4): Heavy duty - foundries, steel mills 

- FEM 5m / CMAA Class E (Service Class 5): Severe duty continuous operations - steel production 

 Choosing the correct duty class ensures optimal crane lifespan, safety, and cost-efficiency. Underspecified cranes wear prematurely, while overspecified cranes increase unnecessary capital investment.

A: Yes, Kino Cranes focuses on tailor-made overhead cranes to suit tough working conditions: 

-Hazardous working areas with explosive gas and flammable dust: Explosion proof cranes fitted with ATEX and IECEx certified parts, anti-spark materials and dedicated electric configurations 

-Dusty working sites like cement factories and grain processing lines: Fully sealed structure, dust-proof motors and easy-to-clean structural layout 

-High temperature working scenarios including steel factories and foundries: High temperature resistant materials working steadily up to 500°C, heat insulation structure and professional cooling setup 

We own an experienced engineering team with more than 18 years of practical experience, capable of developing matched custom crane solutions for various industrial fields all over the world.

A: To provide an accurate quotation, we need: 

- Lifting capacity (tons) 

- Lifting height (meters) 

- Span length (center-to-center distance between runways in meters) 

- Duty class/usage frequency (FEM or CMAA classification) 

- Building dimensions and constraints (headroom, column spacing, floor conditions) 

- Power supply specifications (voltage, frequency, phase) 

- Operating environment (indoor/outdoor, temperature, hazardous conditions) 

- Special requirements (radio control, VFD, anti-sway systems) 

Typical production turnaround time: 

-Regular single and double girder overhead cranes: 20-30 working days 

-Heavy duty models and custom designed cranes: 35-50 working days 

We can adjust production schedule to speed up delivery for urgent orders
