Super Hercules long life excavator hose introduction

The bending radius of Letone Super Hercules long-life excavator hose is 34% lower than the ISO18752 Class C standard, and the number of hose pulses exceeds 1 million times. With the use of Letone Technology’s self-developed hose connectors and hydrogenated nitrile seals, the service life can be extended With a warranty of more than 5 years (two-year warranty), we strive to provide five "saving" services of "saving time, effort, trouble, money and worry".

Flexibility: low temperature bending, the bending radius is 50% lower than the DIN EN853 standard under the test condition of -40℃; the bending radius of the 1” 42MPa Super Hercules low bend series hose is approximately 250mm

Pulse performance: Test pulse according to 1.33 times of working pressure, more than 1 million pulse performance

Wear resistance: The wear of the super wear-resistant outer layer is 0g in the experimental state.

Explosiveness: 4 times the working pressure.

Super Hercules long life excavator hose

Tube: Nitrile/Neoprene synthetic rubber, suitable for biodegradable hydraulic fluids.
Reinforcement layer: one layer of steel wire braiding (1/2"-3/4"), pulse ≥ 300,000 times; four layers of steel wire winding (1"-2"), pulse ≥ 1 million times.
Outer rubber layer: Standard pipe: no-peel, wear-resistant, weather-resistant synthetic rubber; Wear-resistant pipe: no-peel, high wear-resistance, weather-resistant synthetic rubber;
Super wear-resistant pipe: no-peel, super wear-resistant, weather-resistant UHMWPE.
Temperature range: -40℃~+121℃ (-40℉~+250℉).
Implementation standards: Exceeds ISO18752-AC/CC standards.
Bending radius: 41% less than ISO18752 standard; 47% less than SAE standard; pressure exceeds SAE standard 60%.

Success case

Application cases of excavator hose in construction machinery

It is widely used in various types of construction machinery such as excavators. It has the characteristics of long life (5 years of weather resistance, 2 years of warranty), high pressure (25% higher than SAE/DIN standards), pulse resistance, low bending, etc., and is suitable for excavators. and other large construction machinery.

Successful use of hydraulic hose assemblies

When assembling the hose, the recommended insertion depth was not followed, and the connector came off. Later, the hose assembly was replaced. Before crimping the new hose, mark the outer rubber of the hose according to the insertion depth specified in our sample, and then insert the hose until the edge of the sleeve aligns with the marking line.
