10 Ton Gantry Crane with Low Headroom Chain Hoist for Qatar

Introduction

DQCRANES, a global leader in customized lifting solutions, designed and exported a 10 ton portable gantry with low headroom electric chain hoist to a Qatar-based contractor specializing in oil and gas pipeline installation for confined workspaces. The 10 ton gantry crane for sale to Qatar met the client’s need for mobility, precision, and adaptability in harsh desert conditions.

Client Background

The client, a prominent contractor in Qatar’s energy sector, faced challenges in lifting and positioning heavy pipeline segments (up to 10 tons) across remote, uneven terrain with limited overhead clearance. Existing equipment was either too bulky or insufficient for Qatar’s extreme temperatures and sandy environment, necessitating a portable, corrosion-resistant solution.

Project Requirements

• Load Capacity: 10 tons with a safety factor of 25%.
• Mobility: Easy assembly/disassembly for rapid deployment across multiple sites.
• Low Headroom Design: <1m headroom clearance to operate in areas with height restrictions (e.g., under existing pipelines or temporary shelters).
• Environmental Resilience: Resistance to corrosion from sand, humidity, and temperatures exceeding 45°C.

Design Details

The gantry crane design phase began with a thorough understanding of the contractor's operational needs and the end user's application requirements. DQCRANES' engineering team conducted detailed consultations to ensure all technical and environmental factors were considered.

Structural Integrity: 

• The A-frame gantry crane was designed using high-grade steel to ensure durability and reliability under heavy loads. Finite Element Analysis (FEA) was employed to simulate stress points and optimize the structure for maximum safety and performance.

Portability:

• Given the need for frequent relocation at the pipeline-laying site, the gantry crane was equipped with heavy-duty caster wheels. These wheels were designed for smooth movement on uneven surfaces, ensuring operational flexibility.

Ease of Assembly and Disassembly: 

• Given the need for frequent relocation, the mobile gantry crane was designed for quick assembly and disassembly. This feature reduces downtime and enhances operational flexibility.

Low Headroom Hoist: 

• A low headroom electric chain hoist was selected to maximize lifting height within the 3.5-meter constraint. This design minimized the overall height of the crane while maintaining efficient lifting capabilities.

Corrosion Resistance: 

• To combat Qatar's harsh environmental conditions, including high temperatures and humidity, the portable lifting gantry components were treated with anti-corrosion coatings and weather-resistant finishes.

Safety Features:

• Advanced safety mechanisms were incorporated, including overload protection, emergency stop functions, and secure locking systems for stable operation during lifting tasks.

Manufacturing and Testing

Once the design was finalized, the manufacturing process commenced at DQCRANES' state-of-the-art production facility. Precision engineering techniques were employed to ensure every component met strict quality standards. Key steps in the manufacturing process included:

• Cutting and welding of steel components with CNC machinery for high accuracy.
• Assembly of the gantry frame and installation of the electric chain hoist.
• Application of anti-corrosion coatings and rigorous quality inspections.

Following assembly, the mobile gantry crane underwent comprehensive testing to verify its performance under real-world conditions. The testing phase included:

• Load Testing: The portable gantry was subjected to loads exceeding its rated capacity of 10 tons to ensure structural integrity and operational safety.
• Mobility Testing: The portability of the 10 ton mobile gantry crane was tested on various surface conditions to confirm smooth movement and stability.
• Environmental Testing: Simulations of extreme temperature and humidity conditions were conducted to validate the durability of the anti-corrosion coatings.
• Operational Testing: The low headroom chain hoist was tested for precision lifting and lowering operations, ensuring seamless performance.

The mobile gantry crane successfully passed all tests, meeting both DQCRANES' internal quality benchmarks and international safety standards, such as ISO 9001 and CE certification.

Export

Upon completion of testing, the portable gantry crane was prepared for export to Qatar. DQCRANES ensured that all components were securely packaged to prevent damage during transportation. Detailed operation manuals and maintenance guidelines were provided to the contractor to facilitate smooth deployment.
