Under Running Double Girder Cranes

Under running double girder cranes are an ideal material handling solution for facilities that require maximum hook approach, efficient load distribution, and precision movement within limited headroom environments. Mounted below the runway beams, these cranes allow for seamless integration in spaces where top-running configurations may not be practical.

Key Features & Benefits:
• Dual Girder Strength: Featuring two support girders, these cranes offer enhanced lifting capacity, extended spans, and greater load stability compared to single girder systems.
• Underslung Configuration: Operates beneath the runway structure, making it perfect for facilities with tight overhead clearance or architectural restrictions.
• Smooth Load Travel: Designed for precise, low-vibration movement, under running cranes allow for accurate load positioning along monorails or enclosed track systems.
• Flexible Installation: Can be mounted to existing building structures, reducing the need for separate support columns and allowing for more floor space.
• Increased Hook Coverage: Offers maximum end approach to efficiently cover more of the shop floor, increasing usable workspace.
• Customizable Options: Available with motorized or manual trolleys, radio remote controls, variable speed drives (VFDs), and advanced safety features to meet specific application requirements.

Common Applications:
Under running double girder cranes are used in manufacturing plants, machine shops, maintenance facilities, cleanrooms, and light to medium-duty production lines, where space-saving designs and accurate load handling are critical.

When your facility demands an efficient, low-profile overhead lifting system, under running double girder cranes deliver reliable performance, operational flexibility, and excellent load distribution—all without sacrificing valuable headroom or floor space.
