Double Girder Gantry Crane — Enhanced Product Description

Double Girder Gantry Crane — Enhanced Product Description

Main Purpose

The Double Girder Gantry Crane is designed for heavy material handling operations that require high lifting capacity and long-span coverage. With two main girders supporting the hoisting system, it delivers enhanced strength and stability, making it suitable for lifting large, heavy, or bulky materials in demanding industrial environments.

---

Typical Applications

Double girder gantry cranes are widely used in:

• Industrial yards for handling steel structures, precast components, and heavy equipment

• Factories requiring high-capacity outdoor or semi-outdoor lifting

• Logistics and storage yards for large material transfer

• Construction material yards handling beams, slabs, and machinery

• Heavy manufacturing facilities with continuous lifting demands

These environments benefit from the crane’s ability to operate reliably under high loads and wide spans.

---

Key Features

• Strong and rigid structural design
  The double-girder configuration provides excellent load distribution and structural rigidity, ensuring safe operation under heavy loads.

• High lifting capacity for demanding applications
  Compared to single girder designs, the double girder gantry crane supports higher capacities, making it suitable for heavy-duty material handling.

• Stable operation over long spans
  Designed to maintain stability and smooth movement even when operating across wide spans or uneven outdoor surfaces.

• Greater lifting height and hook travel
  The hoist runs on top of the girders, allowing increased lifting height and improved space utilization.

• Suitable for outdoor and semi-outdoor use
  Built with optional weather protection and corrosion-resistant treatments for reliable performance in open yards.

• Reliable performance with low operational risk
  Engineered for long service life and consistent performance in high-duty industrial environments.
