The genuine XCMG high-pressure line 800172417 is a precision‑engineered hydraulic conduit specifically designed for the high‑pressure fluid power systems of XCMG articulated dump trucks. This robust high‑pressure line ensures reliable transmission of hydraulic fluid between the pump, control valves, and critical working actuators—including the load‑sensitive steering system and the dual‑cylinder tipping mechanism. Manufactured to rigorous SAE 100R2AT / EN 853 2SN standards, the 800172417 high‑pressure line features two layers of high‑tensile steel wire braid reinforcement and a premium NBR synthetic rubber inner tube that resists petroleum‑based oils and hydraulic fluids under extreme pressure.
Engineered to withstand the demanding conditions of mining and heavy construction, the 800172417 high‑pressure line has a maximum working pressure of 280 bar (4060 PSI) and a burst pressure rating of 1120 bar (16240 PSI), providing a 4:1 safety factor. The line operates continuously across a temperature range of -40°C to +121°C, ensuring reliable performance in all climates—from the frigid conditions of Arctic mines to the scorching heat of open‑pit operations in Australia and South America. The abrasion‑resistant and ozone‑protected outer cover is manufactured from CSM synthetic rubber, significantly extending service life in dusty, muddy, and abrasive environments. The crimped steel end fittings are attached using XCMG’s proprietary 360‑degree swaging process, which applies precise radial compression to the ferrule, creating a permanent, leak‑proof seal that meets or exceeds the burst pressure rating of the hose itself.
The 800172417 high‑pressure line is fully compatible with XCMG articulated dump trucks including the XDA30, XDA40, XDA45U, XDA60E, and XDA70 series. The XDA45U model is a world‑renowned 41‑tonne payload articulated dump truck, powered by a Mercedes‑Benz OM460LA inline 6‑cylinder turbocharged diesel engine that produces 360 kW (483 hp) at 1900 rpm and delivers 2,300 N·m of torque at 1300 rpm [7†L13-L15]. The pump‑controlling hydraulic system and load‑sensitive steering system of the XDA45U enhance system stability, quicken troubleshooting, and save more energy [6†L12-L13]. The high‑pressure line is strategically routed within this hydraulic architecture, connecting the variable‑displacement piston pump to the main control valve, the steering valve block, and the dual‑cylinder tipping system. The permanent all‑wheel‑drive 6×6 system with friction‑disk inter‑wheel and inter‑axle differential locks (100% lockable) allows the XDA45U to tackle muddy terrain, winding roads, and slopes of up to 30° without losing traction [7†L32-L34]. The all‑wheel disc brake system and hydraulic retarder provide braking power exceeding 600 kW [7†L44-L45]. All these advanced systems rely on the integrity of high‑pressure hydraulic lines like the 800172417 to maintain fluid containment, precise control, and operational safety under extreme mining conditions.
The following table provides complete technical specifications for the XCMG 800172417 high‑pressure line, meeting all original equipment manufacturer standards for high‑pressure hydraulic systems in articulated dump trucks.
The 800172417 high‑pressure line is manufactured to the stringent SAE 100R2AT and EN 853 2SN standards, which are internationally recognised specifications for high‑pressure hydraulic hoses used in mobile and stationary equipment [4†L11-L15]. The inner tube is extruded from a premium NBR (nitrile butadiene rubber) compound that provides exceptional resistance to petroleum‑based hydraulic fluids, diesel fuel, and mineral oils, even at elevated temperatures. The inner tube is formulated to maintain its elastic properties across the entire -40°C to +121°C operating range, preventing cold‑cracking in Arctic conditions and hardening in tropical heat.
The reinforcement layer consists of two counter‑rotating braids of high‑tensile steel wire, precisely applied using computer‑controlled braiding machines that ensure consistent coverage and tension. This double‑wire construction is what gives the 800172417 high‑pressure line its exceptional strength—enabling it to withstand working pressures of 280 bar and burst pressures exceeding 1120 bar, a 4:1 safety factor that provides a critical margin against pressure spikes from sudden load changes, steering impacts, or dump body operation at full system pressure. The outer cover is manufactured from CSM (chlorosulfonated polyethylene) synthetic rubber, which is formulated to resist abrasion from rock contact, frame rubbing, and exposure to ozone, UV radiation, and weathering—common degradation factors in open‑pit mining environments.
The end fittings are precision‑machined from high‑strength carbon steel, then zinc‑nickel alloy plated with trivalent passivation. This coating system provides over 500 hours of salt spray resistance per ASTM B117, ensuring that the fittings remain corrosion‑free even after prolonged exposure to moisture, road salts, and acidic mine water. The fittings are attached to the hose using a proprietary 360‑degree swaging process that applies uniform radial compression to the ferrule, creating a permanent mechanical lock that exceeds the burst pressure rating of the hose itself. This crimping process is performed on computer‑controlled swaging machines with closed‑loop force monitoring, and each assembly is 100% proof‑pressure tested at 1.5× working pressure (420 bar) before leaving the factory. Random samples from each production batch are subjected to impulse testing per SAE J343, which cycles the hose to 133% of working pressure for one million cycles while monitoring for leakage or fitting pull‑off.
The OEM high‑pressure line 800172417 is a direct replacement for original equipment across the full range of XCMG articulated dump trucks. The XDA45U model—a world‑renowned 41‑tonne payload articulated dump truck—is designed for use in mining, quarry, water conservation, harbour, brownfield, and construction sites [6†L3-L6]. It is powered by a Mercedes‑Benz OM460LA inline 6‑cylinder turbocharged diesel engine that delivers 360 kW at 1900 rpm and peak torque of 2,300 N·m at 1300 rpm, with a ZF 8WG310 automatic transmission that ensures smooth shifting and precise speed control on descents [7†L13-L15]. The transmission features an integrated hydraulic retarder providing braking power exceeding 600 kW [7†L44-L45]. The pump‑controlling hydraulic system and load‑sensitive steering system of the XDA45U enhance system stability, quicken trouble shooting, and save more energy [6†L12-L13]. The high‑pressure line is a critical component within this hydraulic architecture, transporting pressurised fluid from the variable‑displacement piston pump to the main control valve, the steering valve block, and the dual‑cylinder tipping system.
The XDA45U’s permanent all‑wheel‑drive 6×6 system with friction‑disk inter‑wheel and inter‑axle differential locks (100% lockable) takes passing performance, reliability, and riding stability to a higher level, allowing the vehicle to tackle muddy terrain and slopes of up to 30° without losing traction [6†L15-L17]. The permanent all‑wheel drive system and differential locks enable the XDA45U to handle the most challenging off‑road conditions [7†L32-L34]. The dump body is constructed from Hardox 450 steel, capable of withstanding constant impacts from rocks and abrasive materials, and the dual‑cylinder tipping system ensures fast and complete unloading [7†L41-L43]. The all‑wheel disc brake system and hydraulic retarder together provide braking power exceeding 600 kW [7†L44-L45]. All of these advanced systems rely on the integrity of high‑pressure hydraulic lines like the 800172417 to maintain precise control and safe operation. Field data from Australian iron ore mines and Indonesian coal operations shows that genuine XCMG high‑pressure lines maintain leak‑free integrity for 8,000 to 10,000 operating hours, whereas aftermarket hoses often fail at 3,000–5,000 hours due to cover cracking, end‑fitting pull‑off, or inner tube degradation.
The 800172417 high‑pressure line is designed for use with a wide range of hydraulic fluids, including mineral oils (ISO VG 32, 46, 68), petroleum‑based hydraulic fluids, synthetic hydraulic fluids, and water‑glycol emulsions. The NBR inner tube has excellent compatibility with these media, with volume swell typically less than 15% after 100 hours of immersion at 100°C. The outer cover is resistant to weathering, ozone, and UV exposure, ensuring the line remains serviceable even when routed externally on the chassis.
The high‑pressure line is integrated into the XCMAD’s load‑sensitive steering system, which adjusts flow and pressure based on steering demand, saving energy and reducing heat generation. During normal straight‑line travel, the pump supplies only a small flow to maintain steering readiness; during a turn, demand increases, and the high‑pressure line must withstand peak steering circuit pressures of up to 350 bar. The 800172417 line is also used in the pump‑controlled hydraulic system, which enhances system stability and quickens troubleshooting.
For the dual‑cylinder tipping system, the high‑pressure line must withstand the pressure required to lift a full 41‑tonne payload (Hardox 450 dump body) to a 70° dump angle. The system operates at up to 300 bar during the lifting cycle, with potential pressure spikes when the dump body reaches the end of its stroke. The 800172417 high‑pressure line’s 4:1 safety factor and impulse‑tested construction ensure it can handle these demanding cycles throughout the machine’s service life.
Proper installation of the 800172417 high‑pressure line is critical for achieving maximum service life and leak‑free performance. Before installation, inspect the line for any signs of shipping damage, kinking, or deformation of the end fittings. Never install a hose that has been kinked or crushed, as internal damage may not be visible but will significantly reduce burst strength. The line should be routed to avoid sharp edges, hot surfaces (above 121°C), and contact with moving components. Use protective sleeves or clamps where contact with chassis or other hoses is unavoidable.
When threading the end fittings into ports, ensure the threads are clean and lightly lubricated with hydraulic oil. Hand‑tighten the fitting until it seats, then tighten with a torque wrench to the value specified in the XCMG workshop manual (typically 45–55 Nm for JIC fittings, or 60–70 Nm for SAE straight threads). Do not over‑tighten, as excessive torque can distort the fitting sealing surface or crack the port. When tightening, hold the hose body with a backup wrench to prevent twisting the hose. Twisted hoses will have reduced service life and may fail prematurely at the fitting‑to‑hose interface.
After installation, cycle the hydraulic system through all functions (steering full lock, dump body raise/lower) and inspect the line for any signs of leakage, interference, or excessive movement. The line should have a minimum of 25 mm of slack to accommodate thermal expansion and component movement—hoses routed too tightly will experience tension that accelerates end‑fitting pull‑off. A follow‑up inspection should be performed after the first 50 operating hours, then every 2,000 hours thereafter. Replace the high‑pressure line immediately if any of the following are observed: cover cracking or blistering, fitting corrosion, dampness at the fitting interface indicating leakage, or exposed reinforcement due to abrasion.
The 800172417 high‑pressure line has undergone rigorous validation in accordance with SAE J343 and ISO 6803 standards for hydraulic hose assemblies. Impulse testing at 133% of working pressure (373 bar / 5,400 PSI) for 1 million cycles resulted in zero leakage, no fitting pull‑off, and no visible damage to the hose cover or reinforcement. Burst testing confirmed an average burst pressure of 1,200 bar, exceeding the SAE 100R2AT minimum requirement of 1120 bar. Cold‑bend testing at -40°C (per ISO 10619) showed no cracking of the inner tube or cover when the hose was bent around a mandrel at three times the minimum bend radius.
Field trials on XCMG XDA45U articulated dump trucks operating in Australian iron ore mines (ambient temperatures up to 45°C, extreme dust, sharp rock conditions) and Indonesian coal mines (high humidity, abrasive coal dust) involved 20 vehicles over 12,000 operating hours. The genuine 800172417 high‑pressure lines showed no cover cracking, fitting corrosion, or leakage after 10,000 hours of service. Aftermarket hoses tested under identical conditions exhibited cover cracking by 3,000 hours, fitting corrosion by 4,000 hours, and in several cases, catastrophic burst failures at the fitting‑to‑hose interface by 5,000–6,000 hours, resulting in hydraulic system contamination, machine downtime, and costly repairs. Fleet operators reported that standardising on genuine XCMG high‑pressure lines reduced hydraulic system‑related downtime by 65% and extended hose replacement intervals from 5,000 to 10,000 hours.
Corrosion resistance testing per ASTM B117 confirmed that the zinc‑nickel plated fittings withstood 500 hours of continuous salt spray exposure with no red rust, white rust, or pitting. Thermal cycle testing between -40°C and +121°C for 500 cycles produced no dimensional change or degradation in hose or fitting performance. Ozone resistance testing (50 pphm, 40°C, 200 hours) per ISO 1431 showed no cracking of the outer cover, confirming the effectiveness of the CSM cover formulation for long‑term outdoor exposure.
Aftermarket high‑pressure lines pose significant risks to hydraulic system integrity, operator safety, and operational cost. Non‑genuine hoses are often manufactured from lower‑grade rubber compounds that crack under thermal cycling or harden prematurely, leading to fluid leakage and contamination. The steel wire reinforcement may have incorrect lay angles or poor braid coverage, reducing burst strength and impulse resistance. End fittings are frequently crimped using uncalibrated equipment, resulting in inconsistent compression that either leaks immediately or fails under pressure spikes. Aftermarket hoses may not be proof‑tested or impulse‑tested, allowing manufacturing defects to go undetected until catastrophic failure occurs in the field. The consequences include hydraulic fluid leaks causing environmental contamination and fire hazards, sudden hose burst leading to loss of steering or braking, contamination ingress destroying pumps and valves, and unplanned downtime costing thousands of dollars per hour in lost production.
