Weiyuan BMH Type Semi-Gantry Crane
Product Overview
The Weiyuan BMH Type Semi-Gantry Crane is a smart and space-saving lifting solution that combines the benefits of a full gantry crane and an overhead bridge crane. This innovative hybrid design features one leg running on a floor-mounted rail while the other end of the beam travels along a runway rail mounted on the building’s structure. It’s the perfect choice for facilities where a full gantry system is unnecessary or where workspace needs to be kept clear on one side. The BMH Semi-Gantry Crane from Weiyuan delivers efficient, reliable, and cost-effective material handling for a wide range of indoor and outdoor applications.
Product Advantages
Optimal Space Utilization
By using only one floor-mounted rail, the semi-gantry crane frees up valuable floor space on the building side of the work area. This allows for unobstructed movement of forklifts, personnel, and other equipment, maximizing the efficiency and safety of your workspace.
Cost-Effective Installation
A semi-gantry crane requires less structural steel and fewer foundation works compared to a full gantry crane, resulting in a lower initial investment. It leverages your existing building structure for support, making it a highly economical choice for adding lifting capacity.
Versatile Indoor and Outdoor Operation
This crane is perfectly suited for both indoor and outdoor use. It can operate under a larger overhead crane inside a facility to handle localized tasks, or it can be installed outdoors along the side of a building for loading, unloading, and material storage.
Flexible and Customizable Design
Weiyuan engineers each BMH semi-gantry crane to your specific needs. We customize the lifting capacity, span, lifting height, and can even include a cantilever on one or both ends to extend your hook coverage beyond the rails, ensuring a perfect fit for your operation.
Reliable and Smooth Performance
Equipped with a high-quality Weiyuan electric hoist and smooth-traveling end trucks, this crane provides dependable and precise material handling. Options for dual-speed or VFD controls allow for gentle acceleration and accurate load positioning.
Application Scenarios
- Adjacent to Buildings: Ideal for outdoor applications where materials are stored or processed alongside a building wall, such as in stone processing yards, steel stockyards, and precast concrete facilities.
- Manufacturing Workshops: Provides dedicated lifting for a specific production line or work cell without interfering with the main overhead crane, improving workflow and reducing wait times.
- Loading and Unloading Bays: Efficiently services loading docks by lifting goods from trucks and moving them into the facility, or vice versa, keeping the bay area clear.
- Shipbuilding and Heavy Fabrication: Offers localized heavy lifting along the side of large structures like ship hulls or large fabricated components.

FAQ
Q: When should I choose a semi-gantry crane over a full gantry or overhead crane?
A: A semi-gantry crane is the perfect choice when you need lifting coverage in part of a bay, but not the entire width. It’s ideal if you need to keep the floor clear on one side for traffic, or if you want to add a supplemental crane below an existing large overhead crane.
Q: Can a semi-gantry crane be installed outdoors?
A: Yes, absolutely. They are very popular for outdoor applications, especially when installed along the side of a building. We use durable, weather-resistant paint and can provide additional protections like motor rain covers to ensure a long service life.
Q: What is the difference between a box girder and a truss girder for this crane?
A: For most BMH semi-gantry cranes, a single box girder is standard. It provides a clean, strong, and torsionally rigid beam. A truss girder is an alternative that can be lighter and more wind-resistant, but is more commonly used on very large full gantry cranes.
Q: Does Weiyuan provide the runway rail for the wall?
A: Yes, we can supply the complete system. This includes the crane itself, the floor-level rail, and the elevated runway beam and rail. We can also provide technical drawings and guidance for the installation of the runway structure on your building.
Q: How do I get a quote for a 10-ton semi-gantry crane?
A: It’s easy. Contact us with your specific requirements: 1) 10-ton capacity, 2) The required span (distance between the floor rail and the elevated rail), 3) The desired lifting height, and 4) The length of the runway (the distance the crane needs to travel).
