Industrial YZ180t Foundry Overhead Crane for Efficient Molten Metal Handling

Customer Background

Lianyuan Iron & Steel Co., Ltd. (LY Steel), a core enterprise under Hunan Steel Group—one of the world’s Fortune Global 500 companies—is a major high-end steel production base in Central and Southern China.

With an annual capacity exceeding 12 million tons, LY Steel is the world’s largest production base for medium and thin-gauge heat-treated plates and China’s leading supplier of silicon-steel substrates. Its products are widely used in national key projects such as the Hong Kong–Zhuhai–Macao Bridge and Tesla manufacturing facilities.

To modernize its molten-metal handling process and enhance operational safety, LY Steel introduced its YZ180t Foundry Overhead Crane, achieving a breakthrough in intelligent and heavy-duty lifting within high-temperature metallurgy environments.

Project Overview

To improve the efficiency of molten-metal transportation in the steelmaking workshop, Lianyuan Steel deployed the YZ180t Foundry Overhead Crane.

Key specifications include:

• Four-girder, four-rail double-trolley structure
• Lifting capacity: 180 tons (main ladle), auxiliary lifting for casting operations
• Span: 28 m
• Lifting height: 22 m (main trolley), 24 m (auxiliary trolley)
• Hydraulic synchronous lifting system: 5 lifting points, synchronization accuracy ≤ 0.1 mm
• Dual operation modes: wireless remote control + cabin
• Compliance: GB/T 3811 crane design standard, ISO 12482 safety certification
• Environment suitability: high-temperature, heavy-dust steelmaking operations
