In short: A crane electrical overhaul renews the ageing electrical equipment of a crane as a whole: panel, wiring, festoon system, limit switches and earthing. The goal is a safe, reliable crane that passes periodic inspections.
What does an electrical overhaul include?
- Renewal or repair of control and power panels
- Bridge and trolley festoon systems, cables and connectors
- Motor and brake connections, brake rectifiers
- Hoist and travel limit switches, emergency stop circuit
- Power supply line, busbar or cable reel
- Earthing and equipotential bonding, warning light and siren
When is an overhaul needed?
- Low insulation resistance in cables or motors (insulation test)
- Frequent faults, overheating connections and fuse trips
- Worn festoon systems and damaged cables
- Electrical non-conformities in the periodic inspection report
- Cranes that have long been without maintenance or changed owners
Work steps
- On-site inspection and measurements (insulation, earthing, voltage, current)
- Report of findings and agreed scope
- Material preparation and overhaul during a planned shutdown
- Function and safety tests, limit adjustment
- Handover of updated wiring diagrams and test records
As the scope grows the overhaul becomes a crane modernization, adding inverter drives and PLC automation. Regular periodic maintenance keeps the crane safe afterwards.

FAQ
How long does an electrical overhaul take?
It depends on the scope; we prepare materials in advance and carry out the work during a planned shutdown to minimise production impact.
Do you provide documentation after the overhaul?
Yes. Work performed, test measurements and updated wiring diagrams are handed over.
