LD单梁桥式起重机解决方案，适用于多种规格的物料搬运

2025 年 11 月 26 日

Lingyun Industrial Corporation Limited has established an efficient and safe material-handling system by adopting our LD single girder overhead crane. With a lightweight structure, intelligent control, and low maintenance requirements, the equipment is well-suited for precision manufacturing and multi-station coordinated operations. This project provides a flexible production and smart-logistics upgrade solution for industries such as automotive components and high-end equipment manufacturing, supporting the development of modular and intelligent single-girder cranes.

Lingyun Industrial Corporation Limited Overview

Lingyun Industrial Corporation Limited was founded in 1995 and is headquartered in Zhuozhou, Hebei Province, China. The company (stock code: 600480.SH) specializes in the production of automotive metal parts, plastic auto parts, and plastic pipeline systems. Lingyun operates a broad production and cooperation network domestically and internationally, with the capability to design and develop components in sync with car manufacturers and supply parts to both domestic and global automotive clients.

Single Girder Overhead Crane Equipment Overview

The batch of LD single girder overhead crane introduced by Lingyun Industrial Corporation Limited is designed for multi-specification material handling. The cranes feature an I-beam main girder structure with spans ranging from 7.5 to 31.5 meters (customized according to workshop layout) and a lifting height of up to 24 meters. Equipped with CD/MD wire rope electric hoists, they support both pendant control and wireless remote control. With a working duty of A4 and an operating temperature range of –20°C to 60°C, the cranes offer low self-weight and reduced wheel pressure—ideal for precision assembly workshops.

核心应用场景

1.Precision Component Assembly

Tasks:

Lifting engine blocks (8 tons per piece).
Lifting gearbox housings (3 m long, 5 tons).

结果：

±5 mm positioning accuracy through electric-hoist control.
Wireless remote operation increased assembly efficiency by 30% and reduced collision incidents by 80%.

2.Production Line Material Circulation

Tasks:

Transferring aluminum alloy wheel hubs between multiple stations (3 tons per basket)

结果：

The lower-flange trolley design minimizes space occupation, optimizing logistics flow and reducing material turnover time by 45%.

3.Inspection Equipment Support

Tasks:

Assisting CMMs (coordinate measuring machines) in lifting large molds (12 tons)

结果：

A low-headroom design (only 4.2 m under-rail clearance) meets overhead inspection requirements, improving measurement efficiency by 25%.
