In short: A crane control panel manages all crane motions, from the main isolator and contactors to inverters and brake circuits. We build panels for new cranes and replace panels on existing cranes.
What is inside a crane electrical panel?
- Main isolator, fuses and phase sequence / phase failure protection
- Main contactor and emergency stop circuit
- Contactors or inverters (VFDs) for hoist, trolley and bridge
- Brake rectifiers and brake control circuits
- Control transformer and control circuit protection
- Limit switch, overload and warning circuits
- Optional PLC, load display and remote monitoring module
When should a panel be replaced?
- Frequent fuse trips, burnt contactors and recurring faults
- Jerky starting and stopping with contactor control, fast brake wear
- Obsolete equipment without spare parts
- Electrical deficiencies in the periodic inspection report
- Modernizations changing capacity, speed or controls
How we work
- Survey of the crane, motors, brakes and wiring
- Design of wiring diagrams, equipment selection and panel layout
- Manufacture and function testing in our workshop
- Installation and commissioning including inverter settings and limits
- Testing and documentation with insulation tests and updated diagrams
We design crane electrical equipment based on EN 60204-32, the electrical safety standard for hoisting machines. See also crane modernization and crane electrical overhaul.

FAQ
Can the panel of my old crane be replaced?
Yes. Regardless of brand and age, motors and brakes are inspected and a new panel with suitable inverters and controls is prepared.
What are the benefits of an inverter panel?
Smooth starting and stopping, precise positioning, less brake and mechanical wear and lower energy consumption.
