Explore our flagship heavy-machinery replacement solutions engineered to exceed OEM standards under extreme operating cycles.
Modern infrastructure, open-cast mining, deep quarry extraction, and rapid urbanization demand unprecedented duty-cycles from earthmoving fleets. In this high-intensity commercial landscape, the Jenis bucket excavator and equivalent premium configurations represent the pinnacle of bulk material displacement. These excavators are subjected to massive shear forces, continuous hydraulic cycles, and abrasive aggregate contact. Maximizing uptime requires not just structurally reinforced bucket frames, but a flawless synergy between the structural elements and the internal hydraulic and powertrain sub-assemblies.
From the high-pressure hydraulics of main pumps like the K5V212 and K7V63DTP to the mechanical integrity of final drives like the GM60VA, every component must handle extreme spikes in hydraulic pressure and torque. Across global markets in North America, Europe, Australia, and Southeast Asia, operators are transitioning away from generic aftermarket parts to precision-engineered components that feature Information Gain through verified operational data, materials engineering excellence, and specialized factory metallurgy.
Global logistics data indicates that hydraulic failure accounts for up to 35% of unplanned downtime in mining excavators. Implementing verified components prevents hydraulic slippage and thermal runaways.
Jenis bucket configurations demand premium wear plates and highly resilient tooth adapters (such as the Komatsu PC60 adapter) to sustain ground engagement without structural micro-fracturing under sub-zero or high-temperature environments.

In the fast-paced world of construction, the reliability and efficiency of your machinery can make or break a project. We understand that high-quality parts are essential for optimal performance. So we aims to provide top-notch construction machinery parts to make customer's machinery running smoothly.
To improve our service, we set up engine maintenance development. In addition to providing customers with engine assemblies, we can also help customers solve various technical problems encountered in the operation and assembly of engines.
We have our own professional maintenance team and can even be invited by customers to arrange for maintenance technicians to go abroad to help customers repair engines.









Our metrics reflect our commitment to supply chain resilience and engineering expertise.
To sustain leadership in the heavy equipment sector, Guangzhou Vita Construction Machinery Co., Ltd. continuously refines its engineering standards. The focus is on integrating telemetry, advanced coatings, and metallurgical chemistry to support the demanding requirements of future Jenis bucket excavators and companion hydraulic systems.
Our upcoming generation of hydraulic components will incorporate built-in pressure and temperature sensors. This technology allows real-time diagnostics, enabling predictive maintenance schedules and minimizing unplanned machinery downtime.
Combining the robust manufacturing capabilities of Hubei with the global logistics network of Guangzhou.
Our production takes place in our 18,000 square meter factory in Xiangyang, Hubei. It is then coordinated with our foreign trade headquarters in Guangzhou. This structure combines cost-effective manufacturing, local access to raw iron ore materials, and fast container shipping from Hubei ports through Guangzhou.
We source structural steel plates, high-grade silicon steel for alternators, and forged alloy steel directly from national mills. This ensures raw material quality remains consistent despite global supply fluctuations.
With 8 dedicated design engineers on-site, we can transition a custom bucket design or hydraulic valve specification from initial schematic to 3D CAD modeling, casting, machining, and final testing in under 4 weeks.
In deep pit mining operations, excavators run almost continuously. High abrasive forces require buckets equipped with Komatsu PC60-style teeth and adapters made from alloy steel. Heavy hydraulic demand requires final drive assemblies (such as the GM60VA) that can handle high torque loads. This allows excavators to navigate steep inclines with full payloads without overheating the final drive gearbox.
Compact and mid-sized excavators (like the XCMG XE35U, Sany SY35, and LiuGong 9035) operating in urban environments need precise control and quiet operation. The HP5V45 hydraulic pump provides smooth multi-functioning capability, allowing operators to work close to structural foundations and utilities with high precision and low noise.
Laying main oil, gas, or water pipelines requires consistent dig cycles through clay, shale, and rock. Unloading valves (such as the 723-40-57100) prevent pressure spikes in the circuit, protecting main cylinders from hydraulic shock and keeping operators safe during deep trenching work.
Corrosive coastal environments and forestry debris test the seals and housings of heavy machinery. Our hydraulic pumps (like the K5V212) feature specialized external coatings to resist salt-spray corrosion, ensuring long-term reliability in harsh environments.
We ensure that our products comply with the technical regulations and trade standards of major global regions. Each component is manufactured in an ISO 9001:2015-certified facility and undergoes rigorous testing before shipment.
To support global fleet managers, our engineering team provides comprehensive cross-referencing guides to verify fitment and eliminate installation issues. For major projects, our technicians can assist with on-site engine tuning, hydraulic flow adjustments, and wear-rate analysis to help extend component life.
All safety valves, high-pressure pumps, and structural castings are labeled with production batch codes to allow full material traceability from mill to field.
We deploy trained diesel and hydraulic specialists globally to assist with system calibration, major engine rebuilds, and pump diagnostic troubleshooting.
We utilize specialized, moisture-sealed export packaging to protect precision components during ocean transit and simplify local customs clearance.
Expert answers regarding hydraulic tuning, material grades, and installation procedures.
The GM60VA Final Drive is compatible with several 30 to 36-ton excavator platforms, including the Kobelco SK350/SK360, Sumitomo SH350, LiuGong 933/936, and XCMG XE335. To verify compatibility, confirm the number of mounting frame holes, the diameter of the sprocket pilot, and the spline count of the drive shaft. You can also provide your machine's serial number to our engineering department for layout verification.
Our PC60 teeth (part number 201-70-24140) are cast using low-alloy steel that contains chromium, nickel, and molybdenum. We apply a water-quenching process that achieves a core hardness of 48-52 HRC and a surface hardness of up to 54 HRC. This configuration resists impact cracking while limiting abrasive wear in sand, gravel, and clay.
The unloading valve controls pressure release when the joysticks are in neutral, returning excess flow back to the reservoir at low pressure. If this valve becomes worn or clogged, the pump works against constant resistance, which raises oil temperatures, wastes engine power, and increases fuel consumption by up to 8%.
The K5V212 is a heavy-duty pump designed for 45-ton excavators (such as the Cat 345D/349D) and runs at operating pressures up to 34.3 MPa. The K7V63DTP is designed for mid-sized 13 to 15-ton machines (such as the Sany SY135C or XCMG XE150) and operates at a lower displacement rate. Both use variable axial pistons, but they are designed for different system flow demands.
Yes. We support custom bucket design, side cutters, and adapter modifications. Customers can provide technical drawings, or our engineering team can design custom wear components to match your specific application, whether you need heavy-duty rock buckets or high-volume GP buckets.
