The flat cable ÖLFLEX® CRANE F 4G25 from Lapp is a specially developed rubber hose cable for demanding industrial applications. It is particularly suitable for use in crane systems on construction sites and shipyards, where it is used for both fixed installations and flexible applications in cable trolley systems. The cable is also approved 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 especially suitable for outdoor use and industrial environments with high mechanical stress.

Applications
ÖLFLEX® CRANE F 4G25 is designed for applications involving high mechanical stress, movement, and environmental influences such as moisture, dust, or temperature fluctuations. It is frequently used in crane systems, where it is installed along trolleys or in cable trolleys to ensure flexible power and signal transmission. It is also suitable for high-bay warehouses and steelworks, where high loads and movements occur. The cable is approved for elevators up to a suspension length of 50 meters, enabling its use in vertical installations.

Functions and Features in Detail
The cable features a flat design, requiring significantly less space compared to round cables. This is particularly advantageous in narrow or confined installation environments. The flat shape also allows for considerably smaller bending radii, simplifying installation in curves and tight bends. The conductors are color-coded, simplifying identification and installation. The cable is designed to be flexible, meeting requirements for movement and rotation without causing mechanical damage.

Technology Explained Simply
ÖLFLEX® CRANE F 4G25 is a rubber hose cable with a rated voltage of U0/U: 300/500 V. The designation 4G25 indicates that the cable has four conductors, each with a cross-section of 25 mm². The use of rubber as insulating and protective jacket material ensures high mechanical strength and resistance to external influences. The flat shape of the cable reduces space requirements and allows for smaller bending radii, simplifying installation in complex systems. The color-coding of the conductors facilitates installation and maintenance, as the assignment of individual conductors is clearly visible.

Compatibility and Accessories
The cable is designed for use in crane systems, elevators, and high-bay warehouses. It is compatible with application profiles for ÖLFLEX CRANE and ÖLFLEX LIFT cables, as described in selection table A3. Its use in cable trolley systems is specifically intended, making it suitable for mobile installations.

Installation and Mounting
Installation of ÖLFLEX® CRANE F 4G25 typically occurs in crane systems, elevators, or high-bay warehouses. The flat design and small bending radii facilitate routing, especially in curves and tight bends. The cable is designed for both fixed installations and mobile applications in cable trolleys. Mounting does not require special tools or additional mounting materials, as the cable is designed for the intended operating conditions.

Operational Advantages
ÖLFLEX® CRANE F 4G25 offers several operational advantages: the flat design reduces space requirements and allows for smaller bending radii, simplifying installation in confined spaces. High mechanical strength and weather resistance ensure long service life even under harsh environmental conditions. Color-coding of the conductors improves ease of installation and maintenance. The cable is suitable for mobile applications such as cable trolleys and elevators, increasing its versatility.
