Industrial performance certified for extreme high-pressure fluid power transfer.
Analyzing high-pressure hydraulic requirements across Liguria’s maritime, logistics, and metallurgical sectors.
Genoa represents the beating heart of Mediterranean maritime logistics, home to the largest port in Italy by cargo tonnage and container traffic. Running these extensive operations requires heavy machinery that runs non-stop, including mobile cranes, ship-to-shore (STS) container loaders, rubber-tired gantry (RTG) cranes, and high-capacity reach stackers. In these heavy industrial systems, high-pressure steel and rubber hydraulic hoses function as essential flow networks. They must endure continuous duty cycles, high impulse frequencies, and challenging outdoor marine environments.
The local shipyards—stretching from Sestri Ponente to the commercial docks near Genoa Pra’—pose even tougher engineering challenges. Marine hydraulic lines are constantly exposed to salty sea spray, intense UV radiation, and high humidity, which can lead to rapid corrosion. Under these conditions, standard hydraulic hoses often fail prematurely due to steel reinforcement corrosion or rubber degradation. Standard steel wires corrode when they come into contact with sea moisture, leading to micro-ruptures that can cause sudden, dangerous blowouts. B2B purchasers in Genoa need specialized solutions: hydraulic rubber hoses built with high-grade synthetic elastomers (like Chloroprene or Nitrile) and rust-resistant steel wire braiding that complies with European EN 853, EN 856, and ISO 1436 standards.
Beyond maritime applications, the metallurgical factories in the neighboring Ligurian valleys require highly stable systems. In these environments, machinery operates close to high-heat ovens, slag lines, and high-impact stamping presses. Hoses carrying petroleum-based fluids need extreme heat resistance, fire-retardant outer covers, and robust synthetic compounds to prevent industrial fires. To serve companies in Genoa effectively, suppliers must offer both high-performance products and deep technical support. This combination helps companies reduce maintenance downtime and ensure plant safety across all operations.
From an advanced research institute to an industry-leading manufacturer of hydraulic systems.

Adapting hydraulic designs to meet the evolving technical needs of modern industry.
Our research and development focuses on creating advanced synthetic rubber formulas that exceed standard performance limits. Standard hydraulic hoses often struggle with biodegradable synthetic esters and environmentally friendly fluids. To address this, we are developing specialized NBR (Nitrile Butadiene Rubber) and HNBR (Hydrogenated Nitrile) compounds. These materials deliver excellent compatibility, prevent early chemical breakdown, and ensure long-term reliability in sensitive ecosystems like marine ports and offshore drilling operations.
For high-pressure systems, structural stability is essential. Our standard hose line features double-braided high-tensile steel wire structures that exceed standard impulse requirements. Our advanced development path targets multi-layer spiral configurations (such as the 4-spiral and 6-spiral EN 856 4SH and SAE 100 R15 lines) designed to handle extreme pressures and mechanical fatigue. By optimizing the wrap angles on our high-speed steel winding lines, we produce hoses that feature smaller bend radii and better flexible durability under pressure spikes.
The industrial sector is moving rapidly toward predictive maintenance. Kelong is actively researching "smart hoses" that feature built-in sensor layers. By layering thin conductive elements directly into the rubber casing, we can monitor structural fatigue, trace pressure peaks, and detect microscopic leaks before they lead to unexpected downtime. This technology allows Genoa's automated container terminals and shipyards to schedule repairs during planned maintenance windows, avoiding costly emergency breakdowns.
Reviewing our practical installations and technical performance under challenging operating conditions.
We supplied custom high-tensile wire-braided hoses to handle the heavy duty cycles of port cargo loaders. The installation resulted in a 35% reduction in yearly maintenance demands.
Our reinforced hoses were selected to ensure stability in heavy-lift mobile cranes. The hoses maintained reliable hydraulic performance during continuous operation in high-salinity air.
We delivered specialized, marine-grade rubber hoses designed to resist UV and salt damage, ensuring reliable operation on offshore drilling rigs.
Our hydraulic pitch-control hoses were installed in wind turbine nacelles, providing reliable service with low fluid friction and resistance to temperature swings.
Our ultra-high pressure spiral hoses were used in heavy tunnel boring machines (TBMs), demonstrating excellent wear resistance and reliable sealing under continuous vibration.
We design custom hose assemblies and sealing layouts to match your local project specifications.

Supported by over 500 professionals and 180+ technical engineers, we reinvest 7% of our yearly revenue into research and development to maintain our product leadership.
We manufacture to strict ISO 9001 and IRIS standards. Every hose batch undergoes intensive impulse pressure and leak testing to ensure consistent reliability.
Our sealing solutions utilize production systems and machining processes imported from DMH Austria, allowing us to build seals with micron-level accuracy.
Our main high-pressure hydraulic hose manufacturing base uses advanced winding and braiding lines imported directly from Italy. This high-precision system ensures uniform tension and spacing for the steel wire wrapping, resulting in excellent pressure handling, minimal outer diameter variations, and high burst protection.

Wire braided hoses (such as EN853 1SN or SAE 100 R1) offer high flexibility and are ideal for medium to high-pressure lines on mobile cranes and general machinery. Wire spiral hoses (such as SAE 100 R12 or EN 856 4SH) are built for heavy-duty systems that handle continuous high-pressure spikes and severe vibrations, making them the preferred choice for tunnel boring machines and heavy excavators.
Our hoses feature outer rubber layers made from high-grade synthetic elastomers that offer excellent ozone, UV, and salt-mist resistance. The steel wire reinforcement is protected from moisture penetration, preventing the internal corrosion that can cause premature failure in port and marine installations.
