Crane Modernization in the Pulp and Paper Industry
In April 2024, GTAKE successfully completed the modernization of a crane used for handling long-length timber at a pulp and paper industry facility. This project involved replacing outdated and worn-out electrical equipment to enhance the crane’s performance and reliability.
Project Goal
The primary goal was to upgrade the crane’s electrical components, which had been in operation for over 10 years. Frequent failures of the old Simatic S115 controller and the main hoist motor, combined with the discontinuation of the original equipment, necessitated this modernization.
Technical Specifications Post-Modernization
Load Capacity: 26 tons
Crane Span: 33 meters
Outreach: 17.5 + 17.5 meters
Crane Base: 10 meters
Crane Travel Speed: 60 m/min
Trolley Travel Speed: 130 m/min
Hoisting Speed: 60 m/min
Projetct Description
Project Implementation
Implementation Period: January – April 2024
Recipient: Pulp and Paper Industry Facility
Location: Quay wall, designated for unloading long-length timber from railcars, river vessels, and trailers.
Drive Power
Main Hoist: 250 kW
Crane Travel: 8 x 15 kW, controlled by 2 frequency inverters (4 motor-reducers per side)
Trolley Travel: 25 kW
Challenges Addressed
The initial equipment was discontinued, complicating spare parts procurement.
Frequent control system failures and the breakdown of the main hoist motor were impacting operations.
Key Accomplishments
Developed new documentation for the electrical equipment.
Manufactured electric drive panels with modern GTAKE frequency inverters.
Replaced the old controller, including custom application software.
Replaced the main hoist motor and necessary electrical components.
Supervised installation, conducted commissioning, and ensured the crane passed all tests and was fully operational.
Product Advantages of the GK820-52
High Starting Torque: Capable of delivering 200% torque at 0 Hz, ensuring robust initial lifting power.
Enhanced Safety Features: Given the complexity and size of crane machinery, safety is paramount. In 2022, 25 crane-related accidents resulted in 23 fatalities in China, highlighting the importance of reliable safety mechanisms. The GK820-52’s comprehensive safety strategies directly contribute to safer construction environments.
GK820-52 Includes protections for load dropping, slack rope, brake failure, position limit and so on, crucial for the safety and reliability of crane operations.
Results
In April 2024, more than 20 cranes were successfully operating with GTAKE inverters, showcasing our commitment to improving efficiency and performance in industrial applications.
