Double girder EOT Cranes are used to handle heavy-duty material in heavy-duty cycle from 10 tons to 100 tons and more. While a single girder eot crane is designed for light-duty cycles, the double girder overhead crane delivers superior lifting power with stability and durability.
Structural Superiority & Design
It featured two main bridge girders and a hoist mechanism that travels on top of rails on the fixed upper part of the girders.
Enhanced Lift Height: Because the hook travels between two bridges, find more headroom compared to single-girder and underslung cranes.
Maintenance Platforms: These cranes generally include a full-length walkway, service of the motors and gearboxes.
Technical Specifications: Double vs. Single Girder
| Technical Feature | Double Girder Specification | Engineering Benefit |
|---|---|---|
| Lifting Capacity | 20 Tons to 500+ Tons | Engineered for the heaviest industrial lifting requirements. |
| Span Length | Up to 50 Meters+ | Provides structural integrity over massive factory widths. |
| Duty Classification | M5 to M8 (ISO Standard) | Designed for high-frequency, 24/7 continuous operation. |
| Maintenance Access | Integrated Full-Length Walkways | Safe access for critical lubrication and gearbox audits. |
| Headroom Efficiency | Top-Running Crab/Hoist | Optimizes vertical space by placing the hoist above the girders. |

Advanced Lubrication for Heavy Duty Cycles
In a double girder crane, eot crane oil changes depend upon the workload, which can be significantly handled in heavy-duty industries. The friction in hoist and long-travel systems requires high-end to prevent structural fatigue. The main hoist required ISO VG 320 Gear Oil to protect metal-to-metal. On-time grease in the crane’s components avoids crane failure and increases the durability of the wire rope throughout the entire crane.
Versatility with Attachments
Double girder EOT cranes are the primary source for specialised heavy-duty tools, as well as industrial grabs and buckets used for material handling like coal, cement, scrap, etc. Also, a lifting magnet for steel yards.
Technical FAQ
Q: Why choose Double Girder over Single Girder?
Ans: Double girder cranes lift more than single girder cranes and are designed to handle harsh environments.
Q: Can these cranes work outdoors?
Ans: Yes, however, double girder cranes operate outside in the form of a gantry crane with specialised protection and technical functions with high-grade water-resistant motors.
Q: How does the travel speed compare to a Hydra?
Ans: While ahydra crane can travel up to 25 -30 lm/h on roads, a double girder overhead crane travels at a controlled 20-40 meters per minute for safety within the bay.
