📄 Product Description
Product Introduction
The MGB/BMG Double Beam Semi Gantry Crane is a rail-mounted medium-to-large crane featuring a twin main girder box-type structure. The hoisting mechanism adopts QD trolley or CD&MD electric hoist. With legs of different heights (adjustable according to site civil engineering requirements), this semi-gantry crane maximizes site space utilization and is ideal for outdoor material handling applications such as railway freight loading, port cargo transfer and warehouse yard operations.
Key Features
- Double Girder Box-Type Main Beam: High-strength welded twin main beam structure provides exceptional rigidity and load distribution for 10-50 ton rated loads, ensuring long-term operational reliability
- Height-Adjustable Leg Design: One high leg running on elevated runway and one short leg on ground rail, customized according to the civil engineering conditions of the use site
- Flexible Hoist Options: Compatible with QD wire rope trolley hoist for heavy-duty cycles or CD/MD type dual-speed electric hoist for economical lifting, making it suitable for both MGB and BMG series
- Dual Control Modes: Ground pendant push-button control for operator mobility and enclosed cabin control for all-weather outdoor operation
- Space-Optimizing Semi-Gantry Design: The single-side elevated runway configuration eliminates the need for a second elevated structure on the short leg side, significantly reducing civil construction costs and maximizing yard space
- Smooth Rail Travel: Available in upper rail running and lower tire running types, with frequency conversion speed regulation for precise positioning during loading operations
Applications
This double beam semi gantry crane is widely used in outdoor lifting environments where one side operates on an elevated runway structure and the other runs on a ground-level rail. Typical applications include: railway freight yards for container and bulk cargo loading and unloading, port terminals for ship-to-shore cargo transfer, steel stockyards for coil and plate handling, precast concrete yards for heavy component lifting, and general outdoor storage and warehouse logistics. The semi-gantry configuration is also suitable for sites where only one side has an existing elevated structure, making it a preferred cost-effective solution for projects requiring semi-portal crane installations.
