Crane electrics & power supply

Electrics are the nervous system of every crane. MAZ Krantechnik takes care of crane electrics for cranes and hoists of every make: switchgear and control cabinets, wiring, power supply and electrical fault finding – in Vienna, Lower Austria, Burgenland and across Austria.

Switchgear and control cabinets for cranes

We build, extend and renew crane control cabinets – with contactors, protective devices, mains isolator and control transformer. We document every change in up-to-date wiring diagrams, so later maintenance and fault finding are quick.

Crane wiring and electrical installation

We rewire crane bridges, trolleys, hoists and operator controls, or replace damaged power and control cables. Worn cables and loose terminals are among the most common causes of intermittent faults – a clean installation prevents them.

Power supply: conductor rails and festoon systems

For a crane to run reliably, its power supply has to be right. We install, renew and repair:

• Conductor rails along the crane runway, including current collectors
• Festoon cable systems for trolley travel
• Supply cables, mains connection and crane isolator switch

We fix typical faults such as contact problems, worn carbon brushes or damaged flat cables permanently, not just temporarily.

Electrical fault finding

If the crane fails or keeps switching off, we trace the fault systematically through power supply, control cabinet, wiring, limit switches and drives. We fix the cause and check the crane before it goes back into service. In an emergency, call our 24/7 breakdown service.

Safety technology

Emergency stop, limit switches, mains isolation and protective devices must work reliably. We check, repair and retrofit them – on older cranes too.

Crane electrics and controls from one team

Electrics and controls belong together. For new PLC controls and radio remote controls see Crane controls & automation. Renewing all the electrics of an older crane is often part of a crane modernisation.
