Maintenance

High availability & reliability through proper, periodic maintenance

The magnet systems are designed for lowest maintenance and feature an impressively long service life. However, periodic and proper maintenance of all components is an important prerequisite to keep the systems running reliably and safely. In some cases, maintenance tasks are not properly carried out. This can be for a number of reasons, such as:

• Lack of know-how
• Lack of specific magnet system knowledge
• Lack of resources
• Lack of management commitment
• Constantly changing maintenance providers

The focus is on the following:

• Inspection and maintenance of spreader beam and suspensions
• Inspection of the magnets
• Inspection and maintenance of plugs, cables and cable drums
• < li>Inspection and testing of the electrical control system
• Inspection and test of the backup battery
• Inspection and adjustment of the battery charger
• General lubrication service
• Over all function check
• Creating a report for each system documenting all checks, errors and defects.

Upon the completion of these checks TRUNINGER issues a certificate to the customer, confirming the system is in perfect condition technically and that it can be operated safely.

Availability and reliability by maintenance

Customers expect high levels of availability and reliable operation from their magnet systems. Breakdowns and interruptions by maintenance need to be kept to an absolute minimum. 
All TRUNINGER systems are designed for lowest maintenance. Nevertheless, some preventative maintenance is necessary for ensuring optimal availability and reliable operation as well as guaranteeing a long service life.

Maintenance levels

TRUNINGER splits maintenance into three levels:
 

Maintenance level 1  Performed by the operator

Training includes:

• Level 1 safety guidelines
• Cleaning tasks and mandatory system checks
• All of operating functions and detection of malfunctions
• Detection of mechanical damages on spreader beams, magnets,  cables or cable reelers
• Read out events on InfoPick
• Any maintenance inside the controller cabinet are subject to higher level 2 training

Maintenance level 2  Performed by trained maintenance staff

Level 2 maintenance training is provided in-house at TRUNINGER and usually lasts 4-5 days.
Training includes:

• Level 2 safety guidelines
• Download the event log via Bluetooth or serial interface
• Track and isolate faults based on the event log
• Replace mechanical or electrical spare parts
• Reboot the magnet system

Maintenance level 3  Performed by TRUNINGER or approved agent

Level 3 maintenance tasks must be performed by TRUNINGER technicians or by TRUNINGER-approved local agents. Level 3 maintenance tasks cover any changes affecting the system specification, functionality or safety.
For example:

• Reworking/replacing magnets or electronic components
• Repairing electrical components
• Changing system configuration or parameters
• Reprogramming or upgrading the main board
• Recommissioning a modified magnet system

Training concept

Drawing on the company’s broad experience as a manufacturer, TRUNINGER provides the opportunity for customer’s staff to be trained for level 1 and level 2 maintenance.
 

On completion of the training the participants receive a TRUNINGER certificate. The participants are registered in a database to keep track on their qualification.
