Excavator Hydraulic Wrist Product Details
1. Product Overview
Our excavator hydraulic wrist is a high - performance attachment designed to significantly enhance the functionality and versatility of excavators. It serves as a crucial connection between the excavator's arm and various attachments such as buckets, breakers, and grapples, enabling a wide range of complex operations.
2. Key Features
2.1 Rotation and Tilt Capabilities
- 360° Continuous Rotation: The hydraulic wrist allows for unrestricted 360° rotation, enabling operators to precisely position the attached tool in any direction. This feature is particularly useful in tasks that require working around obstacles or in tight spaces, eliminating the need to reposition the entire excavator frequently.
- ±45° Tilt Angle: With a tilt angle of ±45° on either side, the hydraulic wrist provides excellent flexibility for angled digging, grading, and material handling. It enables the operator to reach areas that are otherwise difficult to access with a standard excavator setup, increasing the efficiency of operations such as trenching along slopes or cleaning ditches.
2.2 High - Strength Construction
- Cast Steel Structure: The main body of the hydraulic wrist is constructed from high - quality cast steel, which offers an optimal balance between strength and weight. This robust construction ensures the durability of the product, allowing it to withstand the harsh working conditions and heavy loads encountered in excavation projects. The cast steel material also provides enhanced resistance to wear and tear, reducing the need for frequent maintenance and replacement.
- Reinforced Components: Critical components such as pins, bushings, and hydraulic cylinders are designed with extra reinforcement to handle the high forces generated during operation. The pins and bushings are made from hardened steel, providing smooth and reliable movement while minimizing the risk of premature failure. The hydraulic cylinders are engineered to deliver consistent and powerful performance, ensuring smooth operation of the rotation and tilt functions.
2.3 Safety - Oriented Design
- Front Pin Locking Mechanisms: To ensure safe attachment and detachment of tools, the hydraulic wrist is equipped with advanced front pin locking mechanisms. These mechanisms, such as the front pin lock hook and front pin lock, provide a secure connection that prevents accidental disengagement of the attached tool during operation. Additionally, some models feature a lock - sensing technology that alerts the operator if the tool is not properly locked in place, further enhancing safety on the job site.
- Compliance with Safety Standards: Our hydraulic wrist is designed and manufactured in strict compliance with international safety standards such as EN474, ISO13031, and SUVA. This ensures that the product meets the highest safety requirements and provides reliable performance in all operating conditions.
2.4 Easy Installation and Tool Changing
- Quick - Change System: The hydraulic wrist is equipped with a quick - change system that allows for rapid and easy attachment and detachment of different tools. This system enables operators to switch between various attachments, such as buckets, breakers, and grapples, within seconds, without the need for additional tools or complex procedures. The quick - change system is designed to be user - friendly and efficient, reducing downtime and increasing overall productivity.
- Compatibility with a Wide Range of Tools: Our hydraulic wrist is designed to be compatible with a wide variety of excavator attachments, making it a versatile solution for different types of projects. Whether you need to perform digging, demolition, material handling, or any other excavation - related task, our hydraulic wrist can accommodate the appropriate tool, providing a seamless and efficient operation.
3. Technical Parameters
- Suitable Excavator Sizes: Our hydraulic wrist is available in different models to suit excavators ranging from 2 tons to 33 tons. We offer a comprehensive product lineup that can meet the specific requirements of various excavation projects, regardless of the size or type of excavator being used.
- Flow Rate: The required hydraulic flow rate varies depending on the model of the hydraulic wrist and the size of the excavator. Generally, the flow rate ranges from 20 - 40 LPM for the smallest units to 60 - 80 LPM for the largest models. This ensures that the hydraulic wrist receives sufficient hydraulic power to operate smoothly and efficiently.
- Operating Pressure: The maximum operating pressure for all our hydraulic wrist models is 210 bar (3,045 psi). This high - pressure rating allows the hydraulic wrist to generate the necessary force for performing heavy - duty tasks, such as lifting and moving large objects or breaking through tough materials.
- Tilt and Rotation Forces:
- Tilt Force: The tilt force of our hydraulic wrist ranges from 10.6 to 73.0 kN·m (7,818 to 53,842 ft - lb), depending on the model. This strong tilt force enables the attached tool to dig, grade, and manipulate materials with ease, even in challenging working conditions.
- Rotation Force: The rotation force of the hydraulic wrist is in the range of 3.9 to 9.8 kN·m (2,876 to 7,228 ft - lb). This provides the necessary torque for smooth and precise rotation of the attached tool, allowing for accurate positioning and operation.
4. Applications
- Construction Projects: In construction, the excavator hydraulic wrist is widely used for tasks such as foundation digging, trenching for utilities, and material handling. The ability to rotate and tilt the attached bucket or tool allows for more efficient and accurate work, especially when working in tight or complex construction sites.
- Road Construction and Maintenance: For road construction and maintenance projects, the hydraulic wrist is invaluable. It can be used for tasks such as ditch cleaning, slope grading, and asphalt removal. The precise control offered by the rotation and tilt functions enables workers to achieve the desired results with minimal effort and time.
- Municipal Engineering: In municipal engineering projects, such as sewer and water line installation, the hydraulic wrist allows for easy and accurate positioning of tools and materials. It also helps in tasks like street repair and park construction, where the ability to work in different angles and positions is crucial.
- Cable and Pipeline Laying: When laying cables or pipelines, the hydraulic wrist can be used to precisely position the digging or trenching tools. The 360° rotation and ±45° tilt capabilities ensure that the trenches can be dug at the required angles and depths, making the installation process more efficient and accurate.
- Landscaping and Forestry: In landscaping and forestry, the hydraulic wrist can be used with various attachments such as tree grapples and stump grinders. The ability to rotate and tilt the tools makes it easier to handle trees, remove stumps, and perform other landscaping and forestry tasks.
5. Product Benefits
- Increased Productivity: The enhanced functionality of the hydraulic wrist allows operators to complete tasks more quickly and efficiently. With the ability to perform complex operations without repositioning the excavator, the overall productivity of the excavation work can be increased by up to 50% or more, depending on the type of job and the operator's experience.
- Improved Precision: The precise control offered by the rotation and tilt functions of the hydraulic wrist enables operators to perform tasks with greater accuracy. This is particularly important in tasks that require high precision, such as grading or digging in tight spaces, where even a small error can have significant consequences.
- Reduced Fuel Consumption and Environmental Impact: By increasing the efficiency of the excavator, the hydraulic wrist helps to reduce fuel consumption. Since the excavator does not need to be repositioned as frequently, less fuel is wasted, resulting in cost savings and a reduced environmental impact. Additionally, the reduced need for multiple machines on the job site also contributes to a more sustainable operation.
- Versatility: The compatibility of the hydraulic wrist with a wide range of tools makes it a highly versatile attachment. It allows a single excavator to be used for multiple tasks, eliminating the need for specialized equipment in some cases. This versatility not only saves costs but also increases the flexibility of the excavation operation.
