Single Girder Overhead Crane 15 تن
Design & Concept:
The single girder crane features a single bridge beam (تیرآهن) supported on two end trucks. The hoist and trolley run on the bottom flange of the girder. This design is renowned for its cost-effectiveness and ideal for applications where maximum hook height and heavy-duty, continuous service are not the primary concerns.

Single Girder Overhead Crane 15 تن Key Features
- 1. Cost-Efficiency: Lower initial investment due to simpler structure and reduced material requirements.
- 2. Lightweight Design: Puts less stress on the building structure, often making it suitable for existing facilities without heavy reinforcement.
- 3. Space Saving: The compact design requires less headroom, maximizing available vertical space beneath the crane.
- 4. Ease of Installation & Maintenance: Simpler structure leads to quicker installation and easier maintenance.
- 5. Versatility: Perfect for workshops, warehouses, and manufacturing plants with standard duty cycles.

Single Girder Overhead Crane 15 تن Application Scenarios
- 1. انبارها & Storage Facilities: For loading/unloading trucks and moving palletized goods.
- 2. Repair Shops & Maintenance Bays: Handling machinery, engines, and large components.
- 3. Light Assembly Lines: Moving sub-assemblies between workstations.
- 4. Steel Service Centers: Handling bundles of bar stock and sheet metal (moderate use).
Double Girder Overhead Crane 15 تن
Design & Concept:
The double girder crane features two bridge beams supported by two end trucks. The hoist and trolley run on a rail mounted on top of the girders. This design offers superior performance, higher crane hook height, and is built for more demanding, intensive service cycles.

Double Girder Overhead Crane 15 تن Key Features
- 1. Superior Hook Height: The top-running design provides maximum lift, as no space is taken up by the girder depth below the hoist.
- 2. Heavy-Duty & Robust Construction: Designed for higher duty cycles (Class A4-A7), ensuring longevity in severe service environments.
- 3. Enhanced Stability: The dual-girder structure offers exceptional load stability and reduces sway, crucial for precision lifting.
- 4. Greater Span Capability: Can be designed for much longer spans than single girder cranes with minimal deflection.
- 5. Flexibility for Attachments: Easily accommodates specialized lifting attachments like magnets, grabs, or vacuum lifters.
- 6. Cab Operated Option: Suitable for applications where the operator must have a full view from an elevated cab.
