INTRODUCTION
What is this?
The single-girder bridge grab crane is a specialized lifting device that combines a single-girder bridge crane with a grab bucket. It uses an electric hoist or trolley to drive the grab bucket along the main beam, achieving grabbing, transferring, and loading/unloading of bulk materials such as coal, sand, gravel, grain, fertilizer, and scrap steel. If you are handling bulk materials with a limited budget and constrained workshop space, this product is designed for you.
Why choose a single-girder grab crane over a double-girder grab crane?
Compared to traditional double-girder grab cranes, the single-girder solution offers three core advantages:
First, lower investment – simplified structure, lighter self-weight, reducing cost by 30%-40%, especially suitable for small and medium-sized enterprises with limited budgets.
Second, faster installation – lower workshop load requirements, installation time reduced by about 50%, with commissioning completed within 5-10 days.
Third, easier maintenance – fewer components, fewer failure points, grab bucket blades can be replaced individually, resulting in low daily maintenance costs.
Solve your bulk material handling problems with less investment.
What can we do for you?
We understand that every customer has different materials and different working conditions. Therefore, we offer flexible customization options: grab bucket types of electric grab or four-rope grab; control options of pendant, remote radio, or cabin; speed options of single speed, dual speed, or VVVF. Whether your material is wet and sticky or dry and loose, we can match the most suitable grab bucket capacity and structural design.
Unsure? Don't know?
Not sure which grab bucket configuration suits your material? Don't know what grab bucket capacity can handle your workload per shift? No problem. Just tell us: your material type, single grab capacity requirement, and your workshop span. Our engineers will provide you with an accurate quote and CAD drawings within 24 hours.

APPLICATION SCENARIO
1. Coal Yard of Thermal Power Plants
The grab bucket scoops coal from open or enclosed coal piles. The crane travels along the rails and precisely drops the coal into the receiving hopper of the conveyor belt. The anti-spill design of the grab bucket reduces coal leakage and fuel loss. The single girder structure suits the limited installation space of coal yards and can handle continuous, frequent operation cycles.
2. Inland/Port Bulk Cargo Terminals
The grab bucket picks up ore, sand, gravel, or coal from ship holds and transfers them to the shore-side stockyard, or works in reverse to load materials from the stockyard onto ships. High grab speeds reduce vessel port time. Flexible operation adapts to different vessel types and hatch sizes, enabling all-weather operation and improving terminal turnover efficiency.
3. Raw Material Yards of Building Materials/Cement Plants
One crane covers multiple raw material stockpiles. The grab bucket picks up different materials such as limestone, clay, and clinker and drops them into corresponding hoppers. One machine serves multiple purposes, supplying various materials to the batching line. It adapts to high-dust environments and enables quantitative grabbing to assist batching accuracy.
4. Grain Reserve Depots/Grain Processing Plants
The grab bucket transfers corn, wheat, soybeans, and other grains from trucks into storage silos. For outbound operations, the grab bucket moves grain to discharge ports or onto trucks. Gentle grabbing reduces grain breakage. Food-grade contact components are available. Suitable for loading and unloading various types of grain. 5. Raw Material Areas of Fertilizer/Chemical Plants
The grab bucket picks up fertilizers, industrial salt, soda ash, and other materials and transfers them to dissolving tanks or feed hoppers. Anti-corrosion coating is available to handle corrosive materials. The sealed design reduces dust emission and minimizes human contact with hazardous chemicals.
6. Recycling Centers/Waste Treatment Plants
The grab bucket picks up scrap steel, industrial waste, construction debris, and other irregular materials and transfers them to crushers or balers. Heavy-duty grab design with wear-resistant blades extends service life. The rugged structure handles high-density materials and withstands impact conditions.
7. Raw Material Areas of Glass/Ceramic Plants
The grab bucket picks up fine powders such as quartz sand and feldspar powder and drops them into batching weighing systems. Precise quantitative grabbing meets batching accuracy requirements. The well-sealed grab bucket reduces fine powder spillage. Dust covers are available to reduce dust contamination.
