Project Reference

Project Overview:

Henan Mine Crane Co., Ltd. delivered a full set of customized lifting solutions consisting of over 30 sets of diverse cranes to a manufacturing enterprise based in Shandong Province. These cranes are specially deployed for the production of high-end chemical process equipment. Among the whole batch, the 400/100t double girder gantry crane stands out as an industry milestone — it is currently the ultra-large tonnage gantry crane widely applied in the domestic high-end chemical equipment manufacturing sector.

​

Chemical equipment fabrication imposes strict demands on heavy-load hoisting, precise positioning, stable operation and full-process safety monitoring. Our tailor-made 400/100t gantry crane perfectly matches the workshop’s heavy component turnover, assembly and testing workflow of large chemical pressure vessels, reactors and tower equipment.

​

Core Intelligent & Technical Advantages

​

1. PLC+Variable Frequency Control for Precise Intelligent Operation

The whole crane adopts integrated PLC and inverter communication control system, supported by digital filtering technology of frequency converters. It greatly optimizes travel & lifting positioning accuracy, eliminates position deviation during heavy workpiece assembly, and meets micron-level alignment requirements for chemical equipment welding and assembly.

​

2. Anti-Sway System for Higher Safety & Efficiency

The control system is embedded with independent brake logic control, full mechanism anti-sway function and light-load high-speed mode:

• Anti-sway module suppresses load swing during fast traveling, avoiding collision risk to precision chemical workpieces;

• Light-load high-speed mode shortens empty trolley transit time, boosting overall workshop throughput by over 20%;

• Dual main/auxiliary lifting capacity (400t main hook, 100t auxiliary hook) satisfies both ultra-heavy vessel hoisting and small component auxiliary handling.

• ​

3. All-in-One Intelligent Monitoring & Humanized Operation

• Rotatable integrated linked control console in the operator cabin;

• Real-time safety & data monitoring system with HD display, visualizing lifting weight, operating speed, motor temperature, brake status and fault alarms in real time;

• Operators can grasp full working conditions at a glance to realize visualized, low-fatigue long-shift operation.

​

Project Value & Industry Significance

This project marks a major technological breakthrough of Henan Mine in serving the chemical equipment manufacturing industry. Our intelligent heavy-duty gantry crane series solves the long-standing pain points of low precision, unstable lifting and insufficient safety monitoring in large chemical workshop hoisting.

Moving forward, Henan Mine will continue to deepen R&D on customized intelligent lifting equipment for the chemical sector, launch more high-performance, reliable crane products, and provide full-lifecycle customized lifting solutions for global chemical manufacturers. We empower the high-quality development of national and international high-end chemical equipment manufacturing with intelligent heavy machinery.
