OEM 801737322 The XCMG Tension Spring LⅢA4×22×32.5 (801737322) is a genuine OEM extension spring engineered for precise load balancing, tensioning, and return force application on XCMG articulated dump trucks. This heavy‑duty tension spring, identified by part number 801737322 with specifications LⅢA4×22×32.5, provides consistent, reliable mechanical force for throttle linkages, brake actuators, hatch closures, and suspension equalizer systems in the most demanding mining and construction environments.
Manufactured from high‑grade oil‑tempered spring steel (DIN 17223 / SAE 9254) with a zinc‑phosphated anti‑corrosion coating, the 801737322 tension spring delivers exceptional fatigue resistance, high tensile strength, and long‑term dimensional stability under extreme cyclic loading and temperature fluctuations (-40°C to +120°C). Its precision‑ground ends and exacting dimensional tolerances ensure a perfect fit without modification.
The 801737322 tension spring features a closed‑end, ground‑flat design for optimal load distribution, a spring rate of 4.5 N/mm, and a maximum deflection of 32.5 mm, making it an essential component for maintaining system responsiveness and safety in your ADT’s mechanical control systems.
The 801737322 Tension Spring is manufactured from premium oil‑tempered spring steel, offering exceptional yield strength and resistance to set‑off under prolonged high‑stress operation.
Its closed‑end, ground‑flat design ensures that the spring sits squarely on its mating components, preventing lateral buckling and maintaining consistent force direction.
The spring’s hook ends are precision‑formed to exact radii, ensuring positive engagement with mounting pins or brackets without stress‑raising sharp edges.
With a spring rate of 4.5 N/mm and a maximum deflection of 12 mm, the 801737322 delivers controlled, linear force for throttle return, brake release, or hatch closure applications.
Its zinc‑phosphate coating provides excellent corrosion resistance while maintaining a clean, dry surface that prevents galling on mating hardware.
In demanding applications such as open‑pit mines and heavy construction, the 801737322 delivers reliable, long‑lasting tensioning performance for your ADT’s mechanical control systems.
Articulated dump trucks depend on consistent spring forces for throttle return, brake pedal feel, and engine shutdown mechanisms – all of which are safety‑critical functions.
The 801737322 tension spring ensures that throttle linkages return to idle promptly when the pedal is released, preventing unintended acceleration and reducing fuel consumption.
A tired or broken spring can cause delayed throttle response, erratic idle, or failure to fully disengage brakes, leading to unsafe operating conditions and increased wear.
Field data has shown that ADTs equipped with fresh, correctly‑rated tension springs experience 30% fewer throttle‑related driveability complaints and a 25% reduction in brake drag incidents.
The spring’s high‑cycle fatigue life (≥ 500,000 cycles) ensures it maintains consistent force output over thousands of operating hours, reducing the need for frequent adjustments.
Regular inspection of tension springs is recommended; any signs of corrosion, deformation, or loss of tension should be addressed by prompt replacement.
The 801737322 is produced using high‑speed CNC coiling machines that achieve tight dimensional tolerances, ensuring consistent spring rate and free length across every production batch.
The oil‑tempered steel wire is drawn to precise diameters, with a wire tolerance of ±0.05 mm, ensuring uniform stress distribution along the entire length of the spring.
After coiling, each spring undergoes a stress‑relief heat treatment to eliminate residual stresses, followed by a pre‑setting operation to stabilise length and spring rate.
The hook ends are formed in a secondary operation with precision mandrels, ensuring they align perfectly with the spring axis and engage securely with mounting hardware.
The zinc‑phosphate coating is applied in a controlled bath, providing a uniform crystalline layer that enhances corrosion resistance and serves as a base for rust‑preventive oil.
Every unit undergoes 100% load‑testing at full deflection and visual inspection for surface defects, guaranteeing interchangeability with OEM specifications.
The 801737322 is made from SAE 9254 spring steel, known for its high tensile strength (up to 2000 MPa), excellent toughness, and resistance to relaxation at elevated temperatures.
The oil‑tempered microstructure provides a fine, homogeneous grain that resists fatigue crack initiation, even under high‑frequency cycling.
The zinc‑phosphate coating, combined with a light oil layer, provides corrosion protection exceeding 240 hours in salt spray testing, suitable for coastal and high‑humidity environments.
The coating also acts as a dry lubricant during initial cycles, reducing friction between coils and preventing micro‑welding that can occur with uncoated springs.
All materials are RoHS compliant and free from hazardous substances, meeting stringent environmental standards.
The combination of premium steel and robust coating makes this tension spring ideal for the most abrasive and corrosive mining environments.
The 801737322 is designed for rapid installation using standard hand tools, requiring no special equipment or training.
To replace a worn spring, first relieve the tension by moving the control lever to its neutral position, then use pliers to carefully detach the old spring from its mounting pins.
Inspect the mounting pins and brackets for wear or damage, and clean them if necessary before installing the new spring.
Attach one end of the new 801737322 spring to the fixed bracket, then gently stretch it to engage the other end on the moving lever, ensuring the spring is not over‑extended.
After installation, cycle the mechanism through its full range of motion to verify smooth operation and proper tension.
The entire replacement process typically takes under 10 minutes, minimising downtime during routine maintenance.
Investing in the 801737322 Tension Spring delivers significant long‑term savings by preventing control system malfunctions and the associated downtime and repair costs.
A single throttle sticking event can lead to engine overspeed, transmission damage, or even a safety incident – costs that this spring helps to avoid.
Over a typical 15,000‑hour service life, an ADT’s springs can experience millions of cycles. The 801737322’s fatigue life ensures it lasts the lifetime of the control system.
By maintaining consistent tension, the spring also contributes to precise control feel, reducing operator fatigue and improving productivity.
Field data from a major gold mine showed that replacing all control springs with genuine XCMG units reduced control‑related complaints by 35% over a 12‑month period.
The spring’s easy replacement during scheduled maintenance minimises unplanned downtime.
XCMG is committed to sustainable manufacturing, and the 801737322 reflects this through its recyclable steel and energy‑efficient production processes.
