SEVENCRANE下悬双梁桥式起重机是一种常见的电动小车桥式起重机。双梁桥式起重机的性能参数包括：起重量、起升高度、跨度、机构工作速度、工作高度、轮压等。

SEVENCRANE下悬桥式起重机是一种水平放置在车间、仓库和堆场上方用于吊运物料的起重设备。由于它的两端位于高高的水泥柱或金属支架上，所以看起来像一座桥。桥式起重机的桥架沿着两侧高架结构铺设的轨道纵向运行，充分利用桥下空间吊运物料，不受地面设备阻碍。它是应用最广泛、种类最多的起重机械。

Overhead crane lifting equipment come in two common styles: single girder and double girder cranes. Single girder bridge cranes feature simplicity, lightweight construction, and cost-effectiveness, making them suitable for small and medium-sized lifting operations.

In industry and construction, lifting equipment plays an important role, including cranes and gantry cranes. Although both are mechanical devices used to carry and lift heavy loads, there are some distinct differences in design and purpose between cranes and gantry cranes.

Single girder crane is a common lifting equipment widely used in industry and construction. When choosing lifting equipment, it is crucial to know its maximum load capacity.
