STONE Brand- Product Introduction
Product Advantages
We offer a full range of excavator buckets. No matter what model you need, we've got you covered. If you're not sure, just reach out.
Rugged design
Reinforced structure: The welded structure of Hitachi excavator bucket has been optimized to make the side plate and bottom plate more resistant to deformation and have a longer service life.
Wear-resistant protection: High manganese steel or wear-resistant layer is used in key parts, which is wear-resistant and durable.
Quick-change interface: Supports ISO/SAE quick-change device, which can quickly switch between different working devices.
High cost performance
Affordable price: Compared with the original factory products, our price is more affordable, but the performance is not inferior.
Confident choice: Designed specifically for Hitachi excavators, suitable for mainstream models (such as ZX870H-3, ZX240, ZX360, etc.).
Flexible customization: The capacity, bucket tooth type and material can be adjusted according to your needs to meet your personalized needs.
Strong applicability
Mining operations: 4.5 cubic meters of large capacity bucket, greatly improving loading efficiency. Municipal engineering: 3.0-3.5 cubic meters of general-purpose bucket, flexible and practical.
Narrow construction sites: Customized short bucket arms and compact buckets, easily handle complex terrain.
Safety by design
Anti-splash baffle: The baffle on the back of the Hitachi excavator bucket can reduce the splash of gravel and protect the operator's safety.
Triple locking structure: The bucket teeth are fixed more firmly without worrying about falling off.
Rounded corner treatment: All exposed edges are passivated to avoid scratches.
STONE Brand-Applicable environmen
excavator bucket application scenarios
Provides more possibilities for construction
Mining and large quarries
In large mines and quarries, the Hitachi excavator bucket capacity can reach 4.5 cubic meters, with its super-large loading capacity significantly enhancing loading efficiency, providing strong power support for mining operations, ensuring every step is efficient and stable.
Municipal Engineering
Aiming at the needs of municipal engineering and earthwork transportation, the 3.0-3.5 cubic meter general bucket design can not only meet the excavation needs of larger loads, but also ensure operational flexibility, and can easily cope with urban construction and infrastructure reconstruction.
Special working conditions
In narrow construction sites with limited space or where deep excavation is required, Hitachi excavator buckets can be equipped with short arms and compact buckets (such as the RC-35S), allowing the equipment to flexibly adapt to complex terrain.
STONE Brand-High security
Our Projects
Strengthening structural safety design
By adding X-shaped cross reinforcement ribs (thickness 16-20mm), the overall deformation resistance is increased by 35%, avoiding the risk of bucket cracking due to long-term overload operation.
The key welds adopt double-sided groove welding technology, and ultrasonic flaw detection is performed to ensure that the weld strength reaches more than 90% of the parent material, eliminating the hidden danger of structural fracture.
Impact-resistant material system
The main material is high-strength steel plate (yield strength ≥ 550MPa), which has a 60% higher impact resistance than conventional steel. The key wear areas (bucket lip, tooth seat) are compounded with Hardox500 wear-resistant plate (thickness 25mm).
The Hitachi excavator bucket is equipped with an embedded manganese steel jacket, which can withstand a single-point impact force of 180kN during rock excavation, reducing the risk of cracking or perforation caused by material fatigue.
Active safety configuration
Stress relief grooves and deformation induction zones are preset inside the bucket. When encountering uncontrollable overload (such as bucket jamming in hard rock excavation), the bucket body is preferentially guided to undergo local controllable deformation to avoid sudden failure of the overall structure. At the same time, an overload warning mark is standard. When the bucket tooth wear exceeds the safety threshold (≤30% tooth height), a visual warning is automatically triggered to prevent operational accidents caused by excessive component wear.
Human-machine safety protection
Hitachi excavator bucket back integrated anti-splash baffle, adopts 30 ° inclined diversion design, effectively reduce the range of gravel splash (shortening distance by 40%). Bucket teeth fixed with triple locking structure (bolt + retaining spring + safety pin) to prevent the tooth tip from falling off during operation.
All exposed edges are R5 fillet passivation treatment to reduce the probability of accidental scratches, in line with ISO 20474 construction machinery safety specifications.
Full Process Safety Quality Control
Four levels of testing are implemented from raw materials to finished products: ① steel composition spectral analysis (to ensure carbon equivalent Ceq ≤ 0.45%); ② laser cutting dimensional tolerance control (±1.5mm); ③ infrared thermal imaging monitoring of the welding process (interlayer temperature ≤ 200℃); ④ finished product dynamic load test (simulating 3000 hours of equivalent impact). Each bucket comes with an independent test report and a unique traceability code to achieve quality traceability throughout the entire life cycle.
intellectualized system
Hitachi excavator buckets provide hydraulic pressure threshold setting suggestions to prevent equipment overturning or hydraulic system overload caused by bucket overcapacity.
Optional IoT sensor kits monitor bucket stress distribution and temperature changes in real time, and push warnings through APP when data is abnormal, realizing preventive safety management
Precautions for use
Receiving inspection matters needing attention
Check whether the wooden box or steel frame is obviously deformed or damaged, and confirm that the transport lock is intact.
If the packaging is severely damaged, take photos and record them immediately, and contact the logistics party and the supplier to jointly unpack and inspect the goods.
Check the bucket model label (usually located on the inside of the side panel) to ensure that it is consistent with the order.
Check whether the key parts (bucket teeth, tooth seats, welds) have cracks or deformations, and use a caliper to measure the bucket lip thickness tolerance (allow ±2mm error).
Verify the integrity of the accessory package: including mounting bolts (strength grade 10.9 or above), anti-loosening washers, safety pins and instructions.
Precautions for installation and use of Hitachi excavator bucket
Check the machine parameter table (such as the upper limit of bucket capacity of Hitachi ZAXIS870H-3 is 4.5m³) to confirm that the bucket capacity does not exceed the load limit of the equipment.
Measure the size of the quick-change interface (such as ISO 13031 standard) to ensure that it matches the excavator attachment connector.
Clean the equipment hydraulic pipeline interface and check whether the O-ring is intact to prevent impurities from entering the oil circuit.
Test the equipment hydraulic pressure (refer to the model manual, such as the standard value of 34.3MPa) to ensure that it meets the bucket working requirements.
Install the safety pin and insert the cotter pin to fix it to prevent the bolt from loosening and falling off.
No-load operation: Operate the excavator to open and close the bucket 3-5 times to check whether the movement trajectory is smooth and without jamming.
Load test: Test digging in soft soil to observe whether the Hitachi excavator bucket cuts in at a natural angle and whether there is material adhesion during unloading.
Monitor abnormal noise: Abnormal vibration or metal friction sound may indicate installation deviation, which requires immediate shutdown and adjustment.
