Kubota hydraulic rotating grapple

Types of Kubota Hydraulic Rotating Grapples

The hydraulic rotary grapple has several variations, each of which is ideally suited for a particular type of activity. The Kubota hydraulic grapples perform similar functions in diverse industries but differ in design and technology.

• Multi-Functional Grapples:

Multi-functional hydraulic grapples are designed to have various features that enable them to be used in diverse applications. For example, a Kubota 1.3 grapple has different finger configurations for different material shapes. These multi-functional hydraulic grapples are often interchangeable and can be fixed to different machines for varied operations.

• Specialized Grapples:

These grapples are designed for specific functions. For example, a hydraulic timber grapple is specially designed for logging operations. It has long and slender tongs that can easily pick and stack timber. Similarly, a hydraulic scrap grapple is designed to handle metal scrap. It has a claw-like design with curved tongs that can easily pick up metallic objects.

• Rotating Grapples:

These are hydraulic grapples that are able to rotate 360 degrees. They are ideal for applications that require accurate positioning of the material being handled. Normally, the grapple is fixed on a hydraulic motor that is driven by hydraulic pressure coming from a pump.

Another distinction of rotating grapples is the number of rotational joints. Some models have a single joint responsible for the rotating motion, while others have two joints. The ones with two joints offer a better rotational speed and precision.

• Clamshell Grapples:

The clamshell hydraulic grapples are designed to open from the top and clamp from beneath. This makes them ideal for digging and dumping applications. They are often used in mining operations for earth-moving activities. The clamshell grapple is usually mounted on excavators or cranes.

• Comb Grapple Attachments:

This type of grapple has a combination of traditional claw designs and a comb-style arrangement of fingers. It is able to handle large and irregularly shaped materials while also being able to sift through smaller objects.

Specifications and maintenance of Kubota hydraulic rotating grapple

Specifications

• Operating Pressure: The operating pressure defines the working hydraulic pressure range of hydraulic grapples. The common operating pressure is from 18 to 25 MPa (megapascals).
• Flow Rate: This figure represents the volume of hydraulic oil flowing through the system per unit of time, which is usually cubic meters per minute. A typical flow rate for hydraulic grapples may range from 30 to 90 liters per minute.
• Mounting Size: The mounting size is the physical size and shape of the mounting bracket, which is used to connect the hydraulic grapple to the hydraulic excavator. This may depend on the specific models and applications.
• Weight: The weight of the hydraulic grapple is the heavy figure of the machine itself without load. Typically, a hydraulic grapple weighs between 300 and 800 kilograms.

Maintenance

• Regular cleaning: Regularly use clean water and cleaning fluid to clean the surface of the hydraulic grapple to prevent dirt and debris from clogging hydraulic parts and affecting their normal operation.
• Check hydraulic oil: Check the hydraulic oil frequently to ensure that it is clean and free of impurities. If necessary, replace or add hydraulic oil to ensure proper lubrication and operation of the hydraulic system.
• Inspect hydraulic hoses and connectors: Check hydraulic hoses and connectors of the hydraulic grapple regularly to ensure they are not worn, leaking, or loose. Replace or repair them in time if any problems are found.
• Maintain hydraulic cylinders: Ensure that the cylinders are free from dirt and debris by cleaning their surfaces. Additionally, check the sealing elements to make sure they are in good condition and replace them if they show any signs of wear or damage.
• Check the working parts: Regularly inspect the working parts of the hydraulic grapple, such as clamping plates and rotating shafts, making sure they are properly lubricated and free from excessive wear and looseness. If any problems are detected, they must be resolved immediately.
• Pay attention to the operating rules: Hydraulic grapples should be used following the operating instructions to avoid overloading and misuse, which may cause damage to the equipment and affect its service life.

Scenarios of Kubota hydraulic rotating grapples

• Log handling and sorting

  In lumber yards, sawmills, or forestry operations, the Kubota hydraulic log grapple, which is often mounted on a tractor or excavator, plays a crucial role in log handling and sorting. This equipment efficiently grips and maneuvers logs for various tasks such as sorting, stacking, loading, and unloading. Its operation improves productivity while ensuring the lumber handling process runs smoothly and effectively.

• Tree clearing and land preparation

  In landscaping projects or after a natural disaster, the Kubota hydraulic tree grapple proves invaluable. It's efficient in tree-clearing and land-preparation tasks. By wielding the grapple, operators can precisely remove uprooted trees, shrubs, and root balls. Such efficiency enhances the quality of subsequent construction or landscaping endeavors.

• Demolition and debris removal

  In demolition activities, urban construction sites, or landfill operations, the hydraulic rotating grapple assists in removing debris and conducting demolition tasks. This attachment is versatile enough to handle various forms of debris, including concrete blocks, pipes, and metal shards. Its ability to rotate enhances precision when grasping and placing cumbersome objects. Subsequently, this efficiency paves the way for a tidier work environment and facilitates subsequent construction stages.

• Recycling and waste management

  In recycling facilities or at solid waste management sites, the hydraulic recycling grapple facilitates sorting operations and waste management tasks. Be it paper, plastic, metals , or electronic waste, this rotating grapple handles different kinds of materials with ease. Its rotation ensures effective separation and precise placement of items into designated bins or storage areas. As a result, the functional efficiency of waste management and recycling operations is significantly improved.

• Construction and material handling

  In construction projects or a centralized material storage facility, the hydraulic rotary grapple shines in handling diverse construction materials and tasks. Its versatility makes it a preferred tool for managing items such as steel beams, wooden planks, and insulation materials. When integrated with an excavator or similar machinery, it brings forth a smooth construction operation and enhances productivity in material handling.

How to choose a Kubota hydraulic rotating grapple

Fortunately, the following selection tips can help business buyers of hydraulic grapples to narrow down their options:

• Consider the tractor attachment：

  A tractor grapple attachment for a tractor with the right attachment is essential for effective performance. Apart from the attachment type, businesses need to consider the grapple's connection size. The hydraulic grapple size must match the tractors connection to the hydraulic power source.

• Capacity and size requirements:

  Grapples come in different sizes and capacities to handle various tasks. Businesses need to consider the material type and size they plan to use the hydraulic grapple for. For example, larger grapples are better suited for handling bulky logs, while smaller ones work better for scrap or otherwise smaller material.

• Hydraulic requirements:

  Each hydraulic grapple has its own hydraulic pressure and flow rating. They must match the hydraulic system rating of the machine it will be connected to. Otherwise, the grapple won't perform as it should. A reliable hydraulic power system is non-negotiable for the grapple's smooth rotation and clamping actions.

• Quality and safety features:

  Businesses should go for hydraulic grapples with quality construction and reliable materials. Such a build will provide mechanical stability and resistance to abrasions. When buying hydraulic grapples, it’s preferable to go with those that have grapple fingers designed to pick up materials thoroughly and securely. Consider grapples with built-in overload protection mechanisms and emergency stop buttons.

• Operator controls:

  Selecting a hydraulic grapple with intuitive controls is also a determining factor in the choosing process. Controls that are easy to learn and use will enhance productivity and reduce downtime. The operator's comfort during lengthy operations should also be considered.
