20/2 Ton European Gantry Crane for Guinea Engineering Contractor

Yuantai Crane recently delivered a 20/2-ton European standard double girder gantry crane to a leading engineering contractor in Guinea. This project demonstrates Yuantai’s ability to provide stable, high-precision, dual-capacity lifting solutions for demanding infrastructure and materials-handling environments across West Africa.

Customer Background

The client is a well-known Guinean engineering contractor involved in infrastructure, road construction, and steel structure fabrication. Their operations require frequent lifting of heavy steel beams, concrete elements, prefabricated modules, auxiliary parts, and tools within an open-yard environment.

The contractor had been expanding its fabrication capacity and needed a modern double girder gantry crane that would:
 

• Replace aging lifting equipment
• Increase working efficiency
• Handle both heavy-duty and light-duty loads
• Improve operational safety and precision
• Reduce maintenance downtime

Customer Needs & Initial Communication

During the first technical exchange, the customer shared several core requirements:

1. Dual-capacity operation:

A main hoist for heavy materials (20T) and an auxiliary hoist for precise installation tasks (2T).

2. Stable speed control:

The customer wanted smooth motion for handling long steel structures, especially during slow lifting and precise positioning.

3. European standard performance:

They specifically requested compact hoist designs, optimized energy efficiency, and long service life.

4. Durability in outdoor environments:

Guinea’s humidity, dust, and high temperatures required a crane with enhanced protection for motors, electrical components, and mechanisms.

5. Remote installation support:

Due to a limited local crane technicians, the contractor required remote commissioning and installation guidance from Yuantai’s engineering team.

Communication Details 

Throughout 6 rounds of detailed communication via email and video conferences, Yuantai's sales and engineering teams gained a deep understanding of the client's site layout, material lists, and daily workflows. 



Technical Clarification:
 

• Required lifting cycle frequency
• Voltage compatibility (400V/50Hz/3-phase)
• Preference for both pendant and wireless remote control to support multi-position operations
• Working environmental conditions and IP protection levels

We also focused discussions on the frequency of main/auxiliary hook coordination, span/clearance limitations, and local maintenance capabilities. Based on these details, we quickly identified the MGO models European Standard Double Girder Gantry Crane as the optimal model. We centered the proposal on key features such as dual-hook configuration, variable-frequency drive (VFD) control, and optimized it for dual lifting operations and long-term outdoor use.

Performance Specifications

Main Hoist (20T): Equipped with a dual-speed motor, providing a precise micro-speed of 0.7 m/min (for accurate positioning) and a regular speed of 4.0 m/min, balancing safety and efficiency.

Auxiliary Hoist (2T): Speed range of 0.8-5.0 m/min, enabling high-speed movement for light loads and significantly reducing auxiliary operation time.

Crane Travel Mechanism: Fully equipped with Variable Frequency Drive (VFD) control, enabling smooth speed adjustment from 2.0 to 20 m/min. This ensures soft starting without jerk and smooth braking without swing, effectively protecting the load and structure, while greatly enhancing travel stability and positioning accuracy.

Key Design Highlights

• European Standard Hoist Units: Compact structure, Lower wheel pressures, Reduced energy consumption, Low-noise operation, Long service life with minimal maintenance.
• Dual-Lifting Mechanism: Independent main and auxiliary hoists simultaneously handle both heavy and light loads, reducing equipment idle time.
• Ultimate Smoothness & Safety: Full VFD drive combined with European standards ensures exceptionally smooth operation, protecting valuable components and eliminating safety hazards.
• Intelligent Control, Effortless Operation: Wireless remote control offers unparalleled freedom and visibility for the operator, especially valuable in complex worksites.
• Robust & Highly Adaptive: Enhanced anti-corrosion paint system, sturdy construction, IP55 motors and electrical enclosures, ideal for West African climates, including coastal humidity and dusty construction environments.
• Operator-Friendly Dual Control Modes: Pendant control for ground-level precision + wireless remote control for flexible yard operation.

Applications in Guinea & West Africa

The delivered 20 ton gantry crane supports:
 

• Steel structure fabrication
• Infrastructure construction
• Road and bridge engineering
• Machinery repair and assembly
• Prefabricated module handling
• Port logistic yards
• Mining equipment handling

These applications align with growing West African investment in construction, energy, and materials production.

Remote Installation Service

Considering international travel constraints and project urgency, and the client’s limited technical manpower, Yuantai activated its "Expert Remote Installation Guidance" service:
 

• We provided detailed and clear 3D installation drawings, video tutorials, and part lists in advance.
• During installation, our engineers conducted real-time video calls to guide the client's local team step-by-step through assembly, debugging, and preliminary testing.

This ensured the equipment was installed efficiently, without the need for overseas travel costs, and passed testing on the first attempt with zero safety incidents, earning high praise from the client.
