ACTIVITIES

PRODUCTION PROCESS AUTOMATION
Increasing Your Production Efficiency

We design and implement solutions that eliminate production bottlenecks. We combine advanced control systems, sensors, and mechanical components into one harmonious unit. The result is a higher cycle rate, reduced error rates, and full control over your processes.

TURNKEY MACHINE AND EQUIPMENT MANUFACTURING
Single Partner, Full Responsibility

GRATUBE s.r.o. covers the entire project lifecycle. We relieve you of the burden of coordinating dozens of subcontractors – we deliver mechanics, electrical installation, and software as a single integrated unit. We take full responsibility for deadlines, quality, and final commissioning.

ELECTRICAL DISTRIBUTION BOARD MANUFACTURING
Certified Quality and Precision Assembly

We design and assemble low-voltage control panels up to 1000 V in compliance with the EN 61439 standard. We manage everything from cabinet preparation and copper busbar fabrication to precise component wiring and output testing (insulation, thermal testing, safety). Each project includes a complete inspection report and an EC Declaration of Conformity (CE).

PROTOTYPE MANUFACTURING
Minimize Risks Before Serial Production

We produce functional samples and prototypes used to verify design and functionality under real-world conditions. Early identification of errors in the prototyping phase saves you significant financial resources and time that would otherwise be required for modifications in the later stages of serial production.

MECHANICAL DESIGN
From Idea to Functional Machine

We transform your initial ideas into reliable and safe equipment through a precise engineering process. Every project undergoes risk analysis, concept creation, and detailed 3D modeling phases. The result is comprehensive production documentation backed by structural and functional calculations.

ELECTRICAL ENGINEERING AND DESIGN
Intelligent Integration of Performance and Safety

We design efficient electrical systems with an emphasis on standards and electro-mechanical integration. From block diagrams and architecture selection to final PCB layout and bills of materials (BOM) – our solutions undergo rigorous simulations (EMC, thermal load, safety) to guarantee maximum stability for your installation.

PROGRAMING PLC
The Brain of Your Technology in Compliance with Industrial Standards

We develop robust and readable control software in compliance with the IEC 61131-3 standard. Our goal is to streamline cycles, optimize logic, and provide intuitive HMI interfaces. We manage the entire process, from sequential diagrams and offline simulations to real-time online debugging on-site.

INSPECTION OF DESIGNATED ELECTRICAL TECHNICAL EQUIPMENT
Safety Certified by Experts

We perform professional inspections and testing of electrical installations, lightning protection systems, and appliances. Our inspection technicians guarantee that your equipment is in a safe condition, complies with current legislative requirements, and poses no risk to property or human health.

MACHINE AND EQUIPMENT SAFETY
Prevention that Protects Your Employees

For us, safety is more than just a formal "CE" label. We perform in-depth risk assessments, design safety features, and prepare complete accompanying documentation, including user manuals and safety labeling. We ensure that your machinery complies with the strictest European standards.
