Lifting operations with special technical requirements demand tailored solutions throughout both the design and implementation phases. Engineers at GD Gép és Daru Kft. have encountered numerous challenges that exceed the capabilities of standard crane systems. The experience and technical expertise gained through these projects have enabled the development of uniquely engineered, high-performance lifting equipment.
Crane System Installation in Cleanroom Environments
For a medical-grade injection molding facility, the task was to design and install a crane system compliant with ISO 14644-1 Class 8 cleanroom specifications.
Even during the construction phase, strict measures were applied to prevent contamination. Crane structures were fully wrapped and protected until final installation. During the design and manufacturing process, the following criteria were considered essential:
- No particle shedding from structural components
- Complete containment of lubricants
- No crevices or gaps where dust or contaminants could accumulate
An additional key factor in the design was cleanability. The crane structure was built with smooth, continuous surfaces, and the coating system was selected for its chemical resistance to standard cleanroom cleaning agents. The entire system was painted white to visually and functionally integrate into the clean environment—rendering the crane nearly invisible, with only colored fittings remaining distinguishable. emelik ki.
Custom Designed Overhead Cranes and Telescopic Overhead Crane
At an industrial site in Eastern Hungary, a crane system was required that could adapt flexibly to the architectural constraints of the building while ensuring both maximum lifting height and safe, space-efficient material handling.
Two 3.2-ton overhead travelling cranes were installed on a shared runway. In addition, a custom-engineered telescopic overhead crane with a fork-type lifting attachment was integrated into the facility.
The overhead cranes’ main girders were raised using short spacer segments to fully utilize the vertical lifting range permitted by the building structure.
The standout feature of the project was the telescopic crane, specifically designed to handle 4–6 meter long bar stock materials. The system operates within a multi-row cantilever racking layout and is capable of storing and retrieving bundles at any position. The lifting beam is equipped with four pivoting forks that access any shelf level. The forks are guided by a rigid four-section telescopic column suspended from the trolley, which provides vertical reach sufficient to travel over the racking system.
The control system of the crane includes advanced sensor technology to:
- Detect aisle positions between rack rows
- Monitor fork orientation and movement direction
- Recognize individual rack levels
Movements that could cause collisions between the forks and storage levels are automatically disabled by the system. Precise positioning functions are only executable at low speed, enhancing operational safety. This design enables efficient storage and retrieval, even within compact racking layouts occupying minimal floor area.
Conclusion
The customized crane systems developed by GD Gép és Daru Kft. offer reliable and efficient solutions in industrial settings where conventional crane configurations are unsuitable. Whether dealing with cleanroom constraints, spatial limitations, or precision material handling tasks, our engineering-driven approach and hands-on experience ensure the delivery of optimized lifting solutions tailored to the customer’s specific requirements.
