Double-girder Grab Crane

The double-girder grab crane is a heavy-duty lifting device primarily used for handling bulk materials. It consists of a bridge frame, trolley traveling mechanism, small trolley, grab bucket, and electrical equipment. This variant of the bridge crane uses a grab instead of a traditional hook for lifting and transporting bulk materials.

Product Introduction

Features

1.Sturdy Structure: The double-girder design provides greater rigidity and stability, enabling it to handle heavy loads.
2.Flexible Grab: The grab can open and close at any height, adapting to various operational heights. Available in standard and toothed varieties for different material types.
3.Safe Operation: Equipped with both cab and wireless remote control options, allowing operators to choose based on the environment. Safety features include overload limiters, large displays, and protective devices.
4.Versatile Use: Suitable for industries like metallurgy, cement, and chemicals, handling materials such as limestone, mineral powder, coke, coal, sand, and ore. The crane can also operate outdoors with precautions against rain and slipping.
