7.5 Ton Overhead Crane for Sri Lanka Power Plant: CEB Compliant & Anti-Corrosion

11 Apr, 2026

This case involves a complete delivery project by KUANGSHAN CRANE for a 7.5-ton European single girder overhead crane supplied to the electrical equipment warehouse of the Lakvijaya Power Station in Sri Lanka.

The project strictly complied with the tender specification LV/T/2024/0001 issued by the Ceylon Electricity Board (CEB). Technical design and acceptance were executed in accordance with BS 466:1984, the standard for general electric overhead traveling cranes. In addition, specialized anti-corrosion customization was implemented to address the high-humidity and high salt spray conditions along Sri Lanka's western coastal region.

From design, manufacturing, inspection, and logistics to installation, commissioning, and load testing, the project was delivered through a full closed-loop process. The equipment successfully passed the official CEB acceptance in a single attempt and is now operating reliably in the power station warehouse.

Project Background: Sri Lanka Power Industry Tender Project

This procurement is part of an official tender issued by the Ceylon Electricity Board (CEB), applied to a key national thermal power base—the Lakvijaya Power Station electrical equipment warehouse.

• Application scenario: Indoor handling of electrical equipment
• Environmental conditions: Coastal area with high humidity and high salt spray
• Project constraints: Must comply simultaneously with CEB tender procedures and BS 466:1984 technical standards
  

CEB Tender Compliance

This project was executed in accordance with:

1. CEB Tender Specification LV/T/2024/0001
   Covering bidding procedures, contract execution, performance guarantees, payment milestones, and official acceptance processes.
2. BS 466:1984 Standard for Electric Overhead Traveling Cranes
   Covering structural design, manufacturing requirements, installation tolerances, safety configurations, electrical systems, load testing, coating, and visual inspection.

These two frameworks serve distinct but complementary roles and together form the mandatory entry requirements for crane procurement in Sri Lanka's power industry.

Customized Solution and Implementation Highlights for Overhead Crane

The overhead crane was designed and manufactured strictly in accordance with BS 466:1984, with enhanced focus on corrosion resistance for coastal conditions.

Overhead Crane Structural Design

• Configured as a 7.5-ton European single girder overhead crane in strict accordance with tender specifications
• Main girder adopts a 16 mm hot-rolled flat steel box structure
• Welding inspected by Radiographic Testing (RT) and Ultrasonic Testing (UT), meeting required strength and rigidity standards
• Overall stiffness and deformation comply with DIN/FEM standards
• Smooth structural transitions at corners to reduce stress concentration

Safety and Mechanisms

• Dual-stage hoisting limit switches
• 360° rotating enclosed hook with safety latch
• Crane and trolley buffers with derailment protection
• Hoisting mechanism equipped with fail-safe brake (power-off braking)

Electrical System

• Protection class: IP65
• Motors with built-in thermal protection
• Phase failure protection relay (PFR)
• Festoon cable power supply system with stainless steel suspension components
• Original English nameplate

Load Testing

• Static load test: 1.25 times rated capacity
• Supplied with an Overhead Crane Certificate of Conformity upon Delivery from the Factory
• Successfully passed acceptance in a single attempt

Coastal Anti-Corrosion Design

To address the high humidity and salt spray conditions of Sri Lanka's coastal environment, the following enhancements were implemented beyond the requirements of BS 466:1984:

1. Surface Treatment: Steel pre-treatment to improve coating adhesion
2. Protective Coating: Anti-corrosion topcoat applied to the entire crane
3. Wire Rope: High-strength galvanized steel wire rope in compliance with specifications
4. Fasteners: All stainless steel components to prevent corrosion
5. Electrical Protection: IP65 sealed design to minimize moisture ingress

These measures significantly improve operational stability and service life in coastal environments.

One-Stop Delivery for CEB Tender Projects

The project was delivered in full compliance with CEB procedures, including:

• Preparation and submission of bidding documents
• Design, manufacturing, and inspection per BS 466:1984
• Secure logistics from Qingdao Port to Colombo Port
• Rail installation, girder assembly, and electrical wiring
• Coordination of on-site load testing and acceptance with CEB
• Handover of complete documentation: certificates, NDT reports, test reports, and installation manuals

Project Outcomes

1. CEB Tender Compliance: All commercial processes, contract execution, and acceptance procedures fully approved
2. BS 466:1984 Compliance: Structure, safety, electrical systems, and testing all meet standard requirements
3. Corrosion Resistance: Equipment performs reliably under coastal high-humidity and salt spray conditions
