YZ200t gjuterikran för lyft av stora skänkar inom ståltillverkning

Customer Company Background

Baogang Group (Inner Mongolia Baotou Steel) is one of China’s major state-owned iron and steel enterprises, known for its large-scale steelmaking capacity and demanding production environment featuring high temperatures, heavy workloads, and continuous casting operations. To support its ongoing modernization and intelligent manufacturing objectives, Baogang Group sought advanced lifting solutions capable of enhancing safety, efficiency, and stability in molten metal handling.

Project Overview

Baogang Group adopted Dafang Crane’s YZ160t Foundry Overhead Crane to upgrade molten metal handling in its steelmaking workshop. The crane features a hydraulic synchronous hoisting system, intelligent monitoring platform, and a four-girder, four-rail structure. These technologies significantly improved lifting efficiency and operational safety, offering an “efficient, safe, and green” logistics solution for metallurgical production.

This project accelerates the application of large-tonnage cranes in ultra-high-temperature metallurgy and stands as a benchmark for industry technological upgrades.

Equipment Profile

The YZ160t foundry crane used by Baogang Group includes:

• Structure: Four-girder, four-rail double-main-girder design
• Span: 28 m
• Lifting Height: 22 m (main trolley) / 24 m (auxiliary trolley)
• Hoisting System: Hydraulic synchronous lifting with five lifting points (synchronization error ≤ 0.1 mm)
• Control Modes: Wireless remote control + operator cabin
• Standards: GB/T 3811 design standard, ISO 12482 safety certification
• Working Conditions: Designed for extremely high temperature and heavy dust metallurgy environments
