THINGS TO CONSIDER WHEN CHOOSING A PORTAL CRANE
THINGS TO CONSIDER WHEN SELECTING A GANTRY CRANE
Turkey’s Most Comprehensive Gantry Crane Guide
Gantry cranes are indispensable industrial lifting systems used for handling and transporting heavy loads in outdoor areas, yards, and large indoor spaces. Their structure—operating on legs fixed to ground-mounted rails—makes them more flexible than overhead cranes and significantly more suitable for outdoor conditions.
When it comes to gantry crane manufacturing in Turkey, Eser Vinç Mühendislik, based in Konya, stands out with over 20 years of experience, heavy-duty production capability, and engineering solutions that provide high strength over large spans. An incorrectly selected gantry crane can result in operational slowdowns, frequent breakdowns, safety risks, and increased costs.
In this comprehensive guide, we examine all the critical technical criteria to consider when selecting a gantry crane at an expert level.
1. What Is a Gantry Crane and Where Is It Used?
A gantry crane is a variation of an overhead crane, with one fundamental difference:
Overhead cranes are mounted on building columns and beams, whereas gantry cranes operate on strong legs fixed directly to the ground.
This structural difference makes gantry cranes essential for many applications.
Main application areas:
-
Outdoor production yards
-
Concrete and precast plants
-
Steel structure manufacturing sites
-
Marble and natural stone processing facilities
-
Logistics loading areas
-
Container loading and unloading zones
-
Shipyards
-
Pipe, profile, and steel coil storage yards
2. Types of Gantry Cranes
Gantry cranes are categorized into three main types. Correct selection starts with choosing the right type.
A) Single Girder Gantry Crane
Features
-
Commonly used for capacities between 1–20 tons
-
Lightweight and economical
-
Low energy consumption
-
Ideal for small and medium-sized enterprises
Advantages
-
Fast installation
-
Low spare part costs
-
High efficiency for light material handling
B) Double Girder Gantry Crane
Features
-
High capacities ranging from 10–200 tons
-
Much more resistant to harsh site conditions
-
Ideal for wide-span working areas
-
Maintenance walkway on the bridge
Advantages
-
Greater lifting height
-
Vibration-free operation over wide spans
-
The most suitable option for heavy industry
C) Semi-Gantry Crane
A hybrid crane system where one side runs on the ground and the other on a wall-mounted rail.
Applications
-
Semi-open facilities
-
Sites requiring space optimization
-
Mold storage areas
-
Semi-open production lines handling long materials
3. Ten Critical Technical Criteria When Selecting a Gantry Crane
Selecting a gantry crane is not merely a price comparison. The wrong choice can lead to:
-
Load safety risks
-
Increased maintenance costs
-
Productivity loss
-
Frequent breakdowns
-
Slower process flow
1) Lifting Capacity
The lifting capacity is the primary criterion.
General rule:
The crane capacity should be at least 20% higher than the heaviest load.
Example:
-
8-ton loads → 10-ton crane
-
12-ton loads → 16-ton crane
This ensures safety and long service life.
2) Span (Bridge Width)
The span should be determined based on:
-
Warehouse width
-
Production line layout
-
Material lengths
Typical values:
-
Precast plants: 20–40 m
-
Steel service centers: 25–50 m
3) Leg Height & Lifting Height
The crane must lift loads without ground interference.
Key points:
-
Leg height
-
Hook height
-
Net height loss due to bridge construction
Insufficient height increases accident risk.
4) Wind Load Resistance (Critical for Outdoor Use)
Essential equipment for outdoor installations:
-
Wind brakes
-
Anemometer (wind sensor)
-
Rail clamps
Eser Vinç equips all gantry cranes with wind braking systems as standard.
5) Ground and Rail Structure
Ground-mounted rails must be properly designed considering:
-
Concrete strength
-
Anchorage system
-
Rail pads and bolts
-
Rail elevation
Eser Vinç performs ground load capacity analysis before each project.
6) Duty Class (FEM / ISO)
-
FEM 3m–4m for heavy-duty processes
-
FEM 2m for standard production
Wrong duty class = early failures + high maintenance costs.
7) Hoisting Unit Quality
The heart of a gantry crane is the hoisting system:
-
Motor brand quality
-
Gearbox thermal resistance under load
-
Drum and wire rope quality
-
Braking system
-
Hook block
Eser Vinç uses CE-certified hoisting units.
8) Safety Systems
Mandatory safety components include:
-
Overload protection
-
Limit switches
-
Emergency stop
-
End buffers
-
Wind brake system
-
Thermal-magnetic protection
9) Automation Features
Modern gantry cranes should include:
-
PLC control panel
-
Variable speed control
-
Anti-sway system
-
Remote control
-
IoT-based data monitoring
Eser Vinç’s automation infrastructure is among the most advanced in the sector.
10) Manufacturer Reliability (Why Choose Eser Vinç?)
Manufacturer experience makes a 50% difference.
Eser Vinç advantages:
-
20+ years of gantry crane production
-
10,000 m² manufacturing facility in Konya
-
Heavy-duty engineering approach
-
Highly durable gantry crane leg structures
-
Hundreds of references
-
Spare parts and service assurance
4. Gantry Crane Prices (2025 Guide)
Prices depend on:
-
Lifting capacity
-
Span
-
Leg height
-
Automation level
-
Wind resistance class
-
Hoisting unit specifications
-
Structural design
-
Duty class
Gantry cranes have project-based pricing; there is no standard price.
