Custom-designed panels, quality components, and reliable control for crane and machine applications.
AC Crane Maintenance designs, manufactures, supplies, installs and upgrades electrical crane control panels, industrial switchgear, VSD crane systems and automation solutions across South Africa and Africa.
We design, manufacture, and install custom electrical control panels for overhead cranes and industrial machinery across South Africa and Africa.
Our systems are engineered for reliability, safety, and long-term performance, giving you precise control of your crane in demanding industrial environments.
In addition to complete panel solutions, we supply high-quality electrical switchgear, crane components, and variable speed drives (VSDs) for both new installations and system upgrades.
We supply complete crane control panels, built to your exact requirements.
From design to commissioning - we deliver turnkey control systems.
We supply a full range of industrial electrical components for cranes, including:
All components are selected for reliability, availability, and long-term serviceability.
We supply and install VSD systems for overhead cranes, improving control and reducing mechanical stress.
Ideal for modern crane upgrades and performance improvements.
Additional benefit: A correctly selected crane VSD system can also improve low-speed torque control, reduce load swing, lower starting current, improve stopping control, and support safer crane movement in demanding production environments.
We upgrade and modernize existing crane systems to improve performance, safety, and reliability.
Perfect for older cranes needing improved performance without full replacement.
These issues lead to reduced efficiency, safety risks, and costly breakdowns.
We provide complete electrical solutions across:
We also:
Whether local or cross-border - we deliver reliable crane electrical solutions.
We keep essential electrical components readily available, ensuring fast turnaround times.
Minimizing downtime is part of our service.
A well-designed electrical control system ensures:
Poor systems lead to:
Your control panel is the brain of your crane - it must be built right.
We build systems that are:
✔ Designed for industrial environments
✔ Easy to maintain and service
✔ Built with reliable, locally available components
✔ Cost-effective over the long term
We don’t just build panels - we build long-term solutions.
From full panel design to component supply and system upgrades, we provide end-to-end electrical solutions for cranes and industrial machinery.
AC Crane Maintenance supports overhead crane control panels, electrical crane switchgear, crane VSD upgrades, hoist control systems, crane panel rewiring, industrial automation upgrades, crane electrical repairs, and complete control panel manufacturing across South Africa and Africa.
You are not simply purchasing a drive - you are investing in a complete high-performance motion control solution designed for smoother crane operation, safer braking, reduced mechanical wear, better load control and long-term electrical protection.
AC Crane Maintenance supplies and integrates high-performance Variable Speed Drive systems for overhead cranes, hoists, gantry cranes, long travel systems, cross travel systems, lifting equipment and heavy industrial motor control applications across South Africa.
A high-performance VSD gives far better control than a standard starter or basic drive. It allows smooth acceleration, controlled deceleration, improved torque control at low speeds and more accurate positioning of the load.
An input choke is installed on the supply side of the VSD to help protect the drive against supply disturbances, current spikes and electrical stress.
On larger crane and hoist drives, braking energy must be controlled properly. When a motor decelerates or lowers a load, it can generate energy back into the VSD. A braking unit helps control this energy and prevents DC bus over-voltage trips.
Brake resistors work with the braking unit by converting regenerated braking energy into heat. This allows the VSD to stop the motor safely and consistently without uncontrolled voltage build-up.
Our VSD systems are built as complete engineered packages, including high-performance drives, input chokes, braking units, brake resistors, MCCB protection, relay cards, control integration and panel upgrades. The result is a stronger, safer and more reliable crane control system designed for demanding industrial environments.
