The flat cable ÖLFLEX® CRANE F 4G35 from Lapp is a specially developed rubber hose cable for demanding industrial operating conditions. It is particularly suitable for use in crane systems on construction sites and shipyards, where it is intended for both fixed installation and flexible use in cable trolley systems. The cable is also suitable for elevators with a maximum suspension length of 50 meters and is used in wastewater treatment plants, steelworks, and high-bay warehouses. Its construction enables weather-resistant use under harsh environmental conditions, making it particularly suitable for outdoor use and industrial environments with high mechanical loads.

Applications
ÖLFLEX® CRANE F 4G35 is designed for applications requiring high mechanical stress, frequent bending, and robust environmental resistance. It is particularly used in the construction industry, port and shipyard operations, and material handling technology. The cable is intended for use in cable trolley constructions, where its flat shape and low bending radius enable optimal space utilization. It is also suitable for high-bay warehouses and elevator systems up to 50 m lifting height, where mechanical load capacity and weather resistance are decisive advantages.

Functions and Equipment in Detail
The cable features a flat design, requiring significantly less space compared to conventional round cables. This is particularly advantageous in tight or confined installation situations. Conductor identification is done by color, enabling simple and secure assignment of individual conductors. The rubber construction ensures high flexibility and mechanical strength, which is required for use in moving systems such as cable trolleys or crane systems. The low bending radii improve mobility and reduce mechanical stress on the cable during frequent bending.

Technology Explained Simply
ÖLFLEX® CRANE F 4G35 is a flat rubber hose cable with a rated voltage of 300/500 V. The designation 4G35 means the cable has four conductors, each with a cross-section of 35 mm². The use of rubber as insulating and protective sheath material ensures high mechanical strength and resistance to external influences such as moisture, oil, and mechanical stress. The flat shape reduces space requirements and enables more compact installation, especially in cable trolleys or when routing in narrow channels. The low bending radii are a key advantage in moving installations, as they extend the cable's service life and reduce the risk of breaks or cracks.

Compatibility and Accessories
The cable is designed for use in crane systems, elevator systems, and high-bay warehouses. It is compatible with the requirements of the respective application profiles, as described in the selection tables A3 of the manufacturer's documentation. Use in cable trolley systems requires special mounting to account for mechanical loads.

Installation and Mounting
Mounting of ÖLFLEX® CRANE F 4G35 is typically done by fixed installation in cable ducts or cable trolleys. The flat shape requires special fastening to ensure even distribution of mechanical loads. When installing in moving systems such as cable trolleys, care must be taken to ensure bending radii are not undershot to maximize cable service life. Installation is typically done without additional protective conduits, as the rubber layer already provides sufficient mechanical protection. Color-based conductor identification simplifies wiring and maintenance.

Operational Advantages
ÖLFLEX® CRANE F 4G35 offers high reliability in operation due to its weather-resistant and mechanically robust construction. The flat design reduces space requirements and enables more compact installation. The low bending radii reduce mechanical stress and increase cable service life, especially in moving installations. Use in crane systems, elevator systems, and high-bay warehouses is determined by the specific requirements of these areas, where the cable provides the necessary protection and flexibility. Color-based conductor identification simplifies installation and maintenance, increasing operational safety.
