Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Semi-Gantry Structure Design – Maximizing Space Utilization
The core advantage of the BMH electric hoist semi-gantry crane lies in its unique semi-gantry structure design. Compared to traditional full gantry cranes, this structure has the following significant advantages:
Saving Top Space: The semi-gantry design features outriggers at the bottom that run along ground tracks, while the top travels directly along the factory's load-bearing beams. This eliminates the need for a complete gantry structure, significantly reducing the overall height and weight of the machine.
High Adaptability:Particularly suitable for locations with height restrictions or where full gantry cranes cannot be installed, such as adding loading and unloading areas to the outside of existing factory buildings, enabling flexible layouts that utilize walls as tracks.
Simple Structure:The semi-gantry design simplifies the structure, facilitates installation, and reduces maintenance costs, making it an economical choice among light-duty lifting equipment.
Flexible Mobility:The traveling mechanism uses dual-wheel drive, providing a small turning radius and allowing free movement in confined spaces, making it particularly suitable for logistics parks, workshops, and other locations with limited space.
Compact and Lightweight Design
The BMH type electric hoist semi-gantry crane incorporates lightweight and compact design principles in its structural design:
Optimized Main Beam Structure: The main beam adopts an anti-torsion box-type or welded structure, resulting in low wheel pressure and light weight, effectively reducing the load requirements on the ground and building structure.
Integrated Hoist: Utilizing CD1, MD1, and other models of wire rope electric hoists as the lifting mechanism, the hoist and gantry structure are highly integrated, resulting in a simple overall appearance and small footprint.
Dedicated Reducer for Lower Crossbeam: The lower crossbeam employs a dedicated reducer design, allowing for a larger working space inside the crane, facilitating material handling and personnel operation.
Improved Space Utilization: The dimensions between the top of the trolley and the rails are minimized, reducing them by 20%~30% compared to traditional products, thus improving space utilization.
Comparison Dimensions: BMH Semi-Gantry Crane vs. Traditional Full-Gantry Crane
Overall Height: Lower
Structural Complexity: Simple vs. Complex
Installation Difficulty: Convenient vs. Relatively High
Suitable for Space-Confined Areas vs. Open Spaces
Manufacturing Cost: Economical vs. Relatively High
Highly Efficient and Reliable Operating Performance
The BMH electric hoist semi-gantry crane excels in operating performance:
High Operating Speed: The trolley travel speed can reach 20 meters per minute. The lifting mechanism is compact, the hook stroke is reasonable, and the working range is wide.
Three-in-One Drive Mechanism: Equipped with a three-in-one drive mechanism (motor + reducer + brake integrated design), the structure is compact and the transmission efficiency is high.
Selectable Lifting Speed: Lifting speeds of 4m/min, 6.3m/min, 8m/min, etc., are available in various specifications, allowing users to flexibly choose according to the characteristics of the goods and the work rhythm; a dual-speed lifting configuration (MD1 hoist) is optional, achieving fast and slow speed control, with slow speed used for precise positioning and fast speed used for routine handling.
Smooth Trolley Operation: The trolley operating speed is typically 20m/min, with smooth operation and accurate positioning.
Comprehensive Safety Protection System
The Weihua BMH electric hoist semi-gantry crane features comprehensive safety configurations:
Multiple Limit Protections: The hoisting mechanism is equipped with upper and lo
Cases
