The single girder EOT Crane is the backbone of modern warehouses, workshops, and small-scale units. These types of cranes are known for maximising floor space and minimising dead weight through high-speed material handling.
Structural Engineering & Design
A single girder crane designed with one main bridge girder and supported by two end carriages. The hoist unit typically runs on the main girder.
Top Running: The crane travels on the top rails of a gantry like a hydra crane on a road, providing the maximum lift height.
Underslung: The crane is suspended from the roof structure configuration.
Technical Specifications & Advantages
| Feature | Single Girder Specification | Operational Benefit |
|---|---|---|
| Capacity Range | Typically 1 to 20 Tons | Optimized for standard fabrication and assembly units. |
| Span | Up to 30 Meters | Provides extensive lateral coverage across large shop floors. |
| Dead Weight | Lower Wheel Loads | Significant reduction in stress on building gantry and columns. |
| Installation | Fast & Modular | Minimized downtime; lower initial CAPEX and OPEX. |

The Critical Role of Oils & Lubrications in a single girder eot crane
To ensure the durability of a single-bridge crane, regular services and maintenance, along with oils & lubrications. Because the cranes operate in all types of industrial environmental conditions.
A. Hoist Gearbox Maintenance:
Using correct ISO VG 220 gear oil prevents the crane breakdown, and supports the cranes while generating significant heat due to high-speed cycling.
B. Wheel & Bearing Protection
The long travel (LT) wheels bear the entire weight of the girder cranes and loads. For the wheel balance using lithium EP2 grease, the lift of the wheels is developed and moves silently across the rails.
carriage.
C. Integrated Safety & Maintenance
When managing a fleet of lifting equipment must be checked every 6 months to ensure it is fall-safe. Also, limit switches prevent the host from crashing, and ensure the attachment micro grabs, magnet, or host to move the material.
Technical FAQ
Q: Can a single girder crane handle 50 tons?
Ans: Generally, no, for loads above 20 tons, it is required to install double girder eot cranes for safe and fast operation.
Q: What is the best oil for a crane operating in high heat?
Ans: ISO VG 320 synthetic is recommended for oil and lubricants in cranes, and maintains the viscosity even when temperatures are above 40 degrees C.
Q: How does it differ from a Piling Rig winch?
Ans: While both lift material, a crane is designed for precision placement, and a pilling rig operates in high-speed extraction.
