AC and DC drive system upgrades for RTG and RMG cranes

Highly efficient products for existing and new cranes

Rubber Tire Gantry and Rail Mounted Gantry cranes are critical to the flow of containers within a port. Once containers are offloaded, these cranes are critical to movement of cargo within and out of the port. Nidec provides a full range of products and services that can keep your existing cranes rolling or power your new ones.

Upgrade obsolete ship to shore crane controls
Durable and reliable solutions for crane control equipment

Nidec has provided safe and reliable systems for cranes manufactured by Kone, Paceco, IMPSA, Kochs, Hanjin, Hitachi, Star, Doosan and ZPMC. Our systems have provided thousands of hours of reliable service and have extended the working lives of cranes all over the world. Nidec systems have also been installed on the newest cranes manufactured, carrying on the Nidec tradition of safe and reliable service.

Upgrades of Existing Systems to Eliminate Obsolescence
One of the largest challenges ports face today is the obsolescence of control equipment on their cranes. Most manufacturers of control equipment obsolete their products every three to five years. With an expected service life on a crane at 20-30 years or more, ports are left with increased maintenance costs and downtime.
Nidec retrofit solutions help container crane users:

• Eliminate downtime due to obsolescence
• Upgrade with hardware that will be supported for many years
• Replace outdated I/O systems with modern ones already in use at the port
• Add enhanced diagnostics to reduce troubleshooting time on cranes

Modern container cranes utilize AC drive technology for control of the crane. Nidec can provide both stand-alone and common-bus AC systems to power your cranes. Common bus systems include both Active Front End as well as DB control.

Nidec’s AC systems provide our customers with the following benefits:

• Proven equipment to ensure our customers’ cranes run reliably
• Active front end systems that provide unity power factor at the source
• Standard protocols to ensure that the system can be maintained and expanded
• Flexibility of Programmable Logic Controller platforms to utilize customer’s existing knowledge base and spare parts
• Advanced diagnostic systems to reduce troubleshooting and downtime
