Why Choose AMS - Official Distributor of Leine & Linde Encoders for the Crane Industry in Vietnam?

This article highlights AMS as the authorized and trusted distributor of Leine & Linde encoders in Vietnam. More importantly, it explores how our solutions empower the crane and lifting industry from retrofit projects to new installations. If you are seeking reliable encoder replacements or want to understand the critical role encoders play in crane systems, this article is for you.

1. Crane Industry Overview in Vietnam

According to IMARC Group, the Vietnam crane market reached USD 214.4 million in 2024 and is projected to hit USD 317.4 million by 2033, growing at a CAGR of 4.45% (2025-2033).

Key Growth Drivers:

• Rapid industrialization and infrastructure development

• Strong progress in construction projects

• Advanced crane design technologies

• Focus on workplace safety and digital integration

Market segmentation includes:

• By crane type: mobile cranes, fixed cranes, marine/offshore cranes

• By application: construction & infrastructure, mining & excavation, offshore & marine, industrial use

A notable example is Vietnam's ambitious USD 2 billion “super port” project, reflecting huge potential in marine and offshore applications.

Since 2023, Vietnam has also piloted the Green Port model, with mandatory criteria expected by 2026. As highlighted by Gemalink Port's management, green port development with advanced technology, modern equipment, and software integration creates long-term value for both operators and customers.

Despite strong growth potential, Vietnam's crane sector faces:

• Severe labor shortages in port operations and equipment handling (2024-2028 industry skills report)

• Dependence on imported equipment and spare parts

• Rising demand for maintenance, monitoring, and safety solutions to reduce operational risks

To address these challenges, reliable technical solutions such as Leine & Linde encoders play a crucial role in ensuring uptime, safety, and efficiency.

2. The Role of Encoders in Crane Systems

Encoders are critical to crane operation, providing accurate, real-time feedback for control, positioning, and safety. Different encoder types are installed across crane systems to optimize performance in each application.

Encoder Installation Points and Functions:

Trolley Position	- Incremental encoders: speed feedback for inverter-driven motors - Absolute encoders: position measurement on the drum
Boom Position	- Encoders mounted on motors and drums for lifting/lowering control - Rugged Leine & Linde encoders withstand harsh port conditions - Optional encoders with FSI (Functional Safety Interface) for added safety
Load Monitoring	- Strain sensors provide bending moment and fatigue data - Fully digital transmission enables seamless integration with crane automation
Hoist Control	- Incremental encoders: monitor speed, position, overspeed/underspeed conditions - Absolute encoders: deliver position data and speed warnings - Encoders with FSI connect directly to safety circuits or emergency brakes
Spreader Position	- Fast and precise feedback ensures stable, repeatable container handling - Incremental encoders: speed control - Absolute encoders: position measurement
Cable Reel Rotation	Prevents cable overstrain and damage by monitoring reel position
Travel Control	- For STS, RTG, and RMG cranes requiring frequent relocations - Leine & Linde encoders provide accurate positioning feedback via multiple fieldbus protocols
Accessories	Leine & Linde offers a wide range of accessories for crane applications, ensuring flexibility and customization.

3. Key Advantages of Leine & Linde Encoders for Cranes & Lifting

Port cranes operate under extreme conditions—humidity, salty coastal winds, heavy loads, and strong vibrations. Leine & Linde encoders are engineered to perform reliably in these environments.

Proven Benefits:

• Robust mechanical design with high ingress protection

• Long service life with minimal maintenance

• Verified performance in heavy-duty crane environments

• Global support network and fast delivery

• Expertise in customized crane and hoist systems

4. Case Study: Why Customers Trust AMS for Crane Encoder Solutions

Recently, a major port operator in Ho Chi Minh City experienced encoder failure within a crane system. With limited availability of replacement parts in Vietnam, operations faced significant downtime risks.

The customer turned to AMS - the official distributor of Leine & Linde encoders in Vietnam. Leveraging our expertise, we recommended the Leine & Linde RHI 503 encoder, which was successfully installed on a Mitsubishi RTG crane.

Results Delivered by AMS:

• Supply of genuine, heavy-duty encoders designed for port crane environments

• On-site technical support during installation and commissioning

• Reliable spare part availability, ensuring equipment longevity and reduced downtime

5. Conclusion

AMS is committed to being Vietnam's most trusted distributor of Leine & Linde encoders, supporting the growth of the crane and lifting industry.
