Variable Frequency Drives (VFDs) are sometimes stored for extended periods of time between uses. If a VFD goes unused for a year or longer, it must be reformed to recondition the DC-bus capacitors and restore its condition to prepare for operation under load.
yourKONECRANES.com gives you quick and easy access to your crane maintenance information. Usage data from TRUCONNECT and maintenance data and asset details from MAINMAN are linked, giving you a transparent view of events and activities over any selected time interval. Aggregated data can be viewed, analyzed and shared quickly, for a single asset or an entire fleet. Insights can be drawn by observing anomalies, patterns and trends, helping you make informed, fact-based, maintenance decisions.
Frequent inspections, while necessary, cannot always catch machinery failure that may be caused by extremely fast crack propagation. A calculation of design life will give information that helps you assess your safe working limits.
The crane hook and bottom block components are stressed during each working cycle. Hooks can fail due to cumulative fatigue. The failures often start as a fatigue crack in the hook shank. Heavy process duty, changes in application, operation with short lifts and long travel distances and the use of below-the-hook lifting attachments can all contribute to premature cumulative fatigue.
The Konecranes Rope Analysis is designed to answer your wire rope and rope reeving questions. The analysis targets individual concerns such as rope selection, rope life, component failures, unexpected rope behavior, accident investigation or improvement opportunities.
Do your cranes suffer from premature wheel wear, rail wear, structural component failures, or drive faults? All of these are common results of incorrect crane geometry. Have your crane operators complained that a crane is moving and making strange noises or positioning incorrectly? CraneQ Crane Geometric Survey helps you to find the root cause of these symptoms to avoid more major problems and costly downtime.
Konecranes Crane Reliability Study (CRS) provides accurate information detailing the current condition and future needs of your crane. CRS guides your maintenance and modernization decisions. It provides information to increase the safety and productivity of your crane.
Wire ropes are one of the most critical parts of your wire rope hoists, and they can contain hundreds of individual strands. Broken strands on the rope exterior can be found by visual inspections, but the condition of the core and inner wire strands cannot be seen. To evaluate the safety of a wire rope, you need to know what’s happening both on the outside and on the inside. That’s why Konecranes offers RopeQ™ Magnetic Rope Inspection.
The Compliance Gap Analysis has been designed to render an expert opinion whether your current crane operations and maintenance practices are in sync with applicable regulatory
requirements and best practices. While it cannot provide absolute conclusions, it can guide you in identifying potential gaps between where you are and where you ought to be regarding compliance. It can provide recommendations to help you mitigate the associated risk.
