Cable reels and Festoon cable systems AKAPP - STEMMANN / AKAPP

Industrial spring-operated cable reels and festoon cable carriers of series R150 and R300 provide safe handling of cables and hoses on cranes and hoists. Reels feature heavy-duty steel spiral springs and drum core diameters starting from one hundred twenty-three millimeters.

Spring cable reels featuring drum core diameters from 123 to 600 millimeters
Galvanized drum bodies and flanges providing optimal atmospheric corrosion protection
Festoon carriers R150 and R300 operating smoothly within steel C-rail profiles
Safe routing of power cables, control cords and fluid hoses without twisting

Design engineering of enclosed conductor bars Multiconductor and 4-Ductor AKAPP - STEMMANN / AKAPP

Enclosed conductor bar systems Multiconductor RN7 and 4-Ductor RN4 developed by AKAPP - STEMMANN / AKAPP in Ede deliver safe electrification for moving industrial equipment.

The primary technological advantage relies on continuous uninterrupted copper conductors drawn throughout the full travel length without intermediate mechanical splices. This continuous configuration avoids voltage variations, eliminates arcing and reduces contact shoe thermal stress.

The rigid profile housing is extruded from self-extinguishing PVC material featuring high impact strength and insulated copper channels.

Equipped with flexible elastomer dust sealing lips along the bottom collector slot, the profile seals internal conductors from aggressive environmental contaminants, atmospheric humidity and dust, thereby ensuring a long operating lifespan for contact elements under demanding production schedules.

High-velocity electrification Pro-Ductor for automated warehousing and intralogistics

The compact flat conductor bar line Pro-Ductor featuring PR2, PR4, PR7 and PR10 profiles is specifically designed to meet the strict structural boundaries of automated warehouses and distribution hubs.

With an installation width of only twenty-seven millimeters, the system mounts flush with floor levels or integrates into guide beams of storage and retrieval stackers. Multi-pole configurations combine electrical power and shielded communication lines.

Pro-Ductor current collector trolleys are engineered to withstand travel velocities of up to five hundred meters per minute alongside intensive acceleration and deceleration cycles.

Snap-action joint clips streamline track assembly at customer facilities, while continuous copper conductors ensure uninterrupted transmission of digital telemetry and automated positioning signals without data dropouts.

Modular mechanical erection and copper conductor clamping in Click-Ductor RC4 and RC7

The modular conductor bar systems Click-Ductor RC4 and RC7 merge rapid field assembly with exceptional versatility for industrial plant modernizations.

Conductor sections arrive on site with factory pre-fitted copper rails, removing the need for arduous manual conductor pulling at elevation inside manufacturing halls. Track sections connect securely using robust external housing joint clamps.

Copper conductor connections utilize spring-loaded snap clips for electrical ratings up to one hundred ten amperes or heavy-duty screw clamps for currents up to two hundred amperes.

The system incorporates expansion joints, isolated maintenance sections and track transfer points, making Click-Ductor an adaptable solution for crane runways, assembly workshops and monorail loops.

Selection, preventive maintenance and wear analysis of K 91 P current collector brushes

Operational reliability of overhead traveling cranes depends directly on the mechanical condition of current collector brushes.

For enclosed AKAPP conductor bars, copper-graphite and carbon contact shoes of series K 91 P and C 91 P offer low contact resistance and gentle friction against copper surfaces. Spring-actuated parallelogram collector arms maintain constant contact pressure regardless of track vibration.

Plant maintenance personnel routinely inspect brush wear using dedicated wear depth indicators.

Based on operational plant requirements, our team supplies individual replacement shoes and tension springs as well as complete collector trolleys rated from thirty-five to one hundred amperes, including multi-head trolley setups handling currents up to three hundred amperes.

Industrial cable reels and Festoon handling systems for cranes and traveling machinery

For machinery installations where rigid conductor bars are impractical due to complex motions or moist environments, AKAPP provides spring cable reels and festoon cable systems.

Industrial spring reels employ high-grade spiral steel springs and incorporate enclosed slip ring assemblies with dust and splash protection. Drum body diameters from one hundred twenty-three to six hundred mm accommodate various cable lengths.

Festoon trolleys of series R150 and R300 travel inside galvanized C-rail tracks and support flat power cords, multi-core control lines and pneumatic hoses.

Integrated rubber buffers absorb impact forces when carriers gather at end stops, facilitating smooth travel while guarding cable jackets against twisting, abrasion and premature fatigue.
