LDY Metallurgical Overhead Crane Export to Algeria: On-Site Span Adjustment & Full After-Sales Support

06 May, 2026

This project involves an LDY 8-ton metallurgical single girder overhead crane supplied by KUANGSHAN CRANE for a small metallurgical plant in Algeria. It serves as a benchmark after-sales case in the North African metallurgical industry, particularly in addressing on-site span deviation correction and cross-border delivery under an LC (Letter of Credit) payment framework.

Due to incorrect span measurement by the client, the crane could not be installed upon arrival. KUANGSHAN CRANE responded within 24 hours, providing compliant modification drawings, certified operation guidance, and a full-process solution covering non-destructive testing and load testing. The equipment was ultimately commissioned successfully. The project was executed under an LC at sight, ensuring a compliant, safe, and efficient resolution to cross-border installation challenges.

Client Background & Project Overview

• Client: SARL PROPULSION MARINE ALGERIE (Algeria)
• Industry: Small-scale metallurgical workshop (high temperature, heavy-duty, continuous operation)
• Equipment: LDY metallurgical single girder overhead crane
• Rated Capacity: 8 tons
• Duty Class: A3

Project Timeline

1. Contract signing & LC issuance
2. Drawing approval → manufacturing → shipment from Qingdao Port → customs clearance at Oran Port
3. Equipment arrival → span mismatch identified → corrective plan issued
4. On-site modification → NDT → load testing → commissioning

Core Issue: The client’s incorrect measurement method resulted in a mismatch between the manufacturing span and site conditions, with no local capability for compliant rectification.

Problem Analysis

Remote inspection by KUANGSHAN engineers identified confusion in span measurement standards:

1. The client measured the clear width between workshop columns: 19,806 mm
2. Standard crane span is defined as the distance between rail centerlines; rails are installed on column brackets, with a design span of 19,364 mm
3. The deviation of 442 mm prevented installation

Correct Overhead Crane Span Measurement Method

• Definition: Rail centerline to rail centerline (S1=S2=S3=S4=S5)
• Requirements:
  • Measure multiple نقاط along the rail (S2–S5)
  • Calculate the average value
  • Distinguish between clear column width and rail center distance
• Verified span: 19,364 mm

KUANGSHAN CRANE After-Sales Solution

1. Technical Assessment & Drawings

Certified welding engineers provided full modification drawings with structural strength verification to ensure safety.

2. Remote Guided Modification

• Stabilize and support the main girder
• Perform precision cutting and groove preparation
• Weld reinforcement plates with visual inspection
• Adjust span to 19,364 mm and recheck wheel alignment

3. Safety Testing & Compliance

Performed in accordance with GB/T 5905:

• Static test: 125% rated load
• Dynamic test: 110% rated load

4. Commissioning

Successful first trial run; crane commissioned for operation.

Logistics, Customs & Payment

• Transport: 40HQ container, Qingdao → Oran
• Customs support: Certificate of Origin, legalized invoice, compliance documents
• Payment: 100% irrevocable LC at sight; documents pre-checked to ensure zero discrepancies

Project Results & Client Feedback

After compliant rectification and testing, the crane passed commissioning in one attempt and has since operated reliably under high-temperature, heavy-duty conditions.

Client Feedback:
“KUANGSHAN CRANE's response speed and professionalism exceeded expectations. Their standardized solution and full technical support helped us avoid delays and major losses.”
