The Darda S1 Hose 10m is a hydraulic twinline hose assembly (highpressure supply + lowpressure return lines) designed for use with Darda hydraulic power packs and hydraulic tools (splitters, crushers, combi tools) that use the S1 twinhose system. The 10m denotes the length of the hose set (10 meters). It is supplied without quickcouplings (male/female connectors are not included) so that users can fit couplings of their choice, or reuse existing couplers.This hose assembly allows the power pack and tool to be located at a distance (10 meters) apart which gives flexibility on the jobsite. It supports remote tool positioning while maintaining hydraulic control and return flow.
Design:
- Twinline design: Two hoses in one assembly (one for highpressure feed to the tool, one for lowpressure return from the tool). This is typical in Darda S1 systems.
- Length: 10m (approx. 33ft) sufficient for many fieldsetups where the splitter is a distance from the power pack.
- No couplings included: The hose assembly is provided without quickcoupling ends, allowing the user to attach their own couplings suited to their system. This means compatibility with specific power packs or tools with dedicated couplers.
- Hose construction: Likely to include a highpressure rated supply hose and a return hose with lower pressure rating; materials, reinforcement, and outer cover selected to resist abrasion, weather, hydraulic fluid, and jobsite conditions.
- Length tolerance & flexibility: The design needs to allow hose routing on job sites (around obstacles, corners) while maintaining hydraulic integrity, minimal elongation, and safe burst pressure.
- Marking/identification: Hose set is typically clearly marked for which line is high pressure vs return, length, pressure rating, manufacture date, and compliance with relevant hydraulic standards.
Applications:The S1 Hose 10m is used in hydraulic demolition or splitting applications with Darda equipment.
- Hydraulic rock splitting: Using Darda splitting cylinders, the hose connects the power pack to the splitter tool allowing the tool to be placed some distance from the pack (e.g., in confined or remote locations).
- Concrete demolition: Between a hydraulic power pack and a Darda combishears, crusher or splitter, where the tool is at the job face and the pack is safely placed a bit away.
- Tool mobility on jobsite: The 10m hose length means the tool operator can move around a planned job area while the pack stays stationary.
- Multiple tool setups: In some setups, a distribution manifold is added at the end of the hose to feed more than one tool sequentially. The Darda literature states: If several splitters are to be connected, a distributor part is attached to the end of the 10m hose.
- Replacement or extension hose: When existing hose is worn or when an extension is needed, this hose set provides a standard length option.
Materials:
- Inner Tube (High-pressure line): Oilresistant synthetic rubber (e.g., NBR, HNBR) – Compatible with hydraulic fluid used in Darda systems.
- Reinforcement (High-pressure line): Multiple steel wire braids or spirals, or textile/steel hybrid – Provides high burst pressure, fatigue resistance.
- Outer Cover (High-pressure line): Abrasionresistant synthetic rubber or polyurethane – Jobsite durability (rock dust, dragging around).
- Inner tube (Return Line): Synthetic rubber suitable for lower pressure, hydraulic return fluid – Return hose does not carry as high pressure but must resist fluid and contamination.
- Reinforcement (Return Line): Usually steel braid or textile braid sufficient for the lower pressure rating – Lower cost than supply line but still rugged.
- Outer Cover (Return Line): Synthetic rubber, abrasionresistant – Similar jobsite durability needed.
