Solid-state motor drive systems to replace ageing controls with many associated benefits.
Many production cranes installed over the past 30 to 50 years operate on contactor control , which now requires constant inspection and maintenance. These systems have become obsolete and parts are either not obtainable or are only available at high cost with long lead times. MH Automation have developed and adapted solid-state motor drive systems to replace ageing controls with many associated benefits.
The multiple benefits of upgrading to a modern control system include
- Increased reliability
- Elimination of electrical maintenance activities
- Improvement in mechanical performance
- Reduction in mechanical wear and maintenance
- Increased simplicity and ease of fault finding
- Improved energy efficiency and energy saving
- Data logging of operation
- Improved motor protection and reduction in motor heating
- Digital interface to facilitate change in operating parameters
- Compliance with current Health and Safety standards
- Automation of crane movements via PLC to repeat or perform programmed sequence
