5 Electronics for lifting equipment
EKO-ENERGIA meets the needs of the market in its offer with a wide range of services for the cranes. We repair, renovate and modernize the electrical part of all types of cranes. We use modern solutions for control of overhead cranes using frequency converters, radio control systems, and power supply for overhead cranes using busbars. We also make applications based on traditional systems of control that is controllers, cassettes and retaining control systems, speed control various mechanisms. (For the range of mechanical scope see our services in Mechanical & Media Offer item 10)
We can execute all the elements needed for efficient and safe operation of the crane, in particular:
contactor cabinets
control systems for the cabs from local pulpits
regulation and start up resistance systems
electrical installations for the cranes
fully furnished cabins with assembly
For the above mentioned tasks our company has the appropriate permissions issued by the Office of Technical Inspection in Krakow. We also provide maintenance and periodic inspections under the provisions of the UDT, preparing cranes to periodic inspections of UDT, including measurements of shock protection.
6 Installations and distribution stations
In our offer you will also find the work connected with installations and execution of assembly and services and maintenance of the electric infrastructure facilities, including proposals for modernization. As part of this work we perform:
Internal electrical installations for power supply and lighting
Power cable lines
Modernization of medium and low voltage switch gears
Power supply for overhead cranes and other mobile receivers, using busbars
Installation of automatic control and signaling systems
Anti-shock protective systems and anti-lightning systems
Data communication networks
We provide servicing for the switchgears, apparatus and equipment under permanent contracts with the customer. EKO-ENERGIA supplies the execution of the periodic reviews of protective measures and other work resulting from bilateral agreements.
