latest company case about Henan Huagong Industrial Group Co., Ltd. certifications

Project Overview

• Project Location: Southeast Asia
• Industry & Application: Metal fabrication & machinery machining workshop
• Equipment Model: LD Type Single-Girder Overhead Crane
• Core Capacity: 5 Ton
• Span Length: 13.5 m
• Working Class: ISO A3 / FEM 1Am
• Control Method: Pendant control & Wireless remote control
• Application: Metal parts handling, workshop production line

Client Challenge & Site Constraints

The client operates a precision machinery production line and urgently required an overhead lifting system to transport heavy raw materials and finished workpieces between workstations.

During the site evaluation, several engineering challenges were identified:

1. Limited Headroom: The existing workshop has a low ceiling clearance, making standard overhead cranes unsuitable without sacrificing critical lifting height.
2. High Daily Frequency: Frequent parts handling demanded smooth starting/stopping, low operational noise, and high structural stability.
3. Ease of Maintenance: The client required a straightforward, robust mechanical structure with readily available spare parts for convenient local maintenance.

Our Tailored Engineering Solution

Based on the workshop civil drawing and production layout, our technical team engineered an optimized LD-type single-girder bridge crane solution:

• Space-Optimized Structure: Adopted a compact main box-girder combined with a low-headroom electric wire rope hoist, maximizing hook approach and gaining up to 15% extra effective lifting height.
• Smooth & Safe Motion: Equipped with soft-start motors, dual-speed lifting, and variable frequency drives (VFD) for travel motions, eliminating load swing during sensitive workpiece positioning.
• Comprehensive Safety Protection: Integrated dual-stage lifting limiters, laser anti-collision sensors, overload protection units, and emergency power-off switches.
• Full-Lifecycle Technical Support: Supplied standard 3D GA drawings, runway beam calculation verification, and step-by-step installation manuals to assist local erection.
• According to the site drawing and working conditions, we recommended LD

type single‑girder overhead crane.

• Main girder: optimized light‑weight single beam design, save vertical space
• Matching electric hoist, reliable European style or domestic hoist optional
• Complete safety device: overload limiter, travel limit switch
• We provided full set drawing, installation guidance document.

All components passed strict factory inspection before shipment.

Project Result

After installation and commissioning, the crane runs smoothly.

It greatly improves material handling efficiency, reduces manual work. The customer is satisfied with product quality and our technical support.

We can customize single‑girder cranes from 1t‑20t for different workshop conditions.
