INTRODUCTION

The LD Type Electric Single-Girder Overhead Crane (Model LD) is the most widely used light-to-medium duty bridge crane in the industry. It consists of a single steel bridge girder (box beam or I-beam) supported by end trucks, with a standard electric wire rope hoist (Model CD1 or MD1) or electric chain hoist running along the bottom flange of the main girder.

APPLICATION SCENARIO

Widely used in general manufacturing workshops, warehouses, logistics centers, assembly lines, and machining shops for material handling, loading, and transferring goods in normal temperature and non-explosive environments.

ADVANTAGES

Cost-effective single girder design that reduces initial equipment investment. The lightweight structure and low wheel load lower the requirements and construction costs of the factory building. Easy to install and maintain. Equipped with reliable electric hoists to ensure smooth, stable, and efficient operation.
