INTRODUCTION
What is this?
The QZ grab crane is a specialized double-girder bridge crane equipped with a motor-driven grab bucket. It uses an electric wire rope trolley to operate the grab, achieving grabbing, transferring, and loading/unloading of bulk materials such as coal, ore, sand, gravel, grain, fertilizer, chemical powders, and scrap metal. If you are handling loose bulk materials in large volumes with high intensity and need a durable, heavy-duty crane for continuous operation, this product is designed for you.
Why choose a QZ grab crane over a standard hook crane with a grab attachment?
Compared to standard hook cranes retrofitted with grab attachments, the QZ dedicated grab crane offers four core advantages:
First, higher grabbing efficiency – dedicated grab mechanism with optimized opening/closing speeds increases cycle productivity by 30%-40% compared to hook-mounted grabs.
Second, greater durability – reinforced girder structure and heavy-duty wheels designed specifically for shock loads and continuous grabbing impact.
Third, specialized control – dedicated grab control system with anti-sway and anti-spill functions, providing precise closing and opening at any height.
Fourth, longer service life – grab-specific rope winding system reduces wire rope wear, extending rope life by 2-3 times.
Solve your bulk material handling problems with a dedicated grab crane.
What can we do for you?
We understand that every customer has different materials, different densities, and different working conditions. Therefore, we offer flexible customization options: grab types of motor grab, four-rope grab, or hydraulic grab; grab bucket capacities from 0.5m³ to 5m³; control options of cabin, remote radio, or pendant; VVVF speed control for smooth grab operation. Whether your material is wet and sticky coal or dry and abrasive ore, we can match the most suitable grab design and bucket capacity.
Unsure? Don't know?
Not sure which grab type suits your specific material? Don't know what grab capacity can handle your shift workload? No problem. Just tell us: your material type and density, required tons per hour, and your workshop or yard dimensions. Our engineers will provide you with an accurate quote and CAD drawings within 24 hours.

APPLICATION SCENARIO
[1] Coal Yards of Thermal Power Plants – The grab scoops coal from stockpiles and precisely drops it into receiving hoppers of conveyor belts. Anti-spill design reduces coal leakage and fuel loss. Heavy-duty structure handles continuous, frequent operation cycles.
[2] Port Bulk Cargo Terminals – The grab picks up ore, sand, gravel, or coal from ship holds and transfers to shore-side stockyards, or loads materials from stockyards onto ships. High grab speeds reduce vessel port time. Flexible operation adapts to different vessel types and hatch sizes.
[3] Chemical Plants – The grab picks up fertilizers, industrial salt, soda ash, and other chemical materials, transferring them to dissolving tanks or feed hoppers. Anti-corrosion coating is available for corrosive materials. Sealed design reduces dust emission and minimizes human contact with hazardous chemicals.
[4] Recycling Centers and Waste Treatment Plants – The grab picks up scrap steel, industrial waste, construction debris, and irregular materials, transferring them to crushers or balers. Heavy-duty grab design with wear-resistant blades extends service life. Rugged structure handles high-density materials and withstands impact conditions.
[5] Raw Material Yards of Steel Mills – The grab handles iron ore, limestone, coke, and other bulk materials, feeding them into conveyor systems or charging hoppers. One crane covers multiple stockpiles, reducing equipment investment.
