Knuckle Boom Crane Attachments Explained

Are you in the construction or heavy machinery industry? If so, you understand the importance of having the right equipment to get the job done efficiently and safely. One such piece of machinery that has revolutionized the industry is the knuckle boom crane. With its versatile design and ability to reach great heights, a knuckle boom crane is an invaluable tool. In this article, we will explore the various knuckle boom crane attachments available in the market that can further enhance the functionality and ease of use of these cranes.



Knuckle boom cranes have gained significant popularity in various industries due to their ability to reach high elevations and manoeuvre in tight spaces. These cranes are known for their articulated arm design, which gives them greater flexibility compared to traditional straight boom cranes. However, their functionality can be further enhanced with the use of attachments.


What is a Knuckle Boom Crane?

A knuckle boom crane, also known as an articulated crane or a loader crane, is a type of crane with a hinged arm. This design allows the crane to fold and unfold similarly to a human finger, providing increased reach and manoeuvrability. Knuckle boom cranes are commonly mounted on trucks or trailers, making them portable and versatile for various applications.


Benefits of Knuckle Boom Crane Attachments

Knuckle boom crane attachments offer several advantages that can make your job easier and more efficient. These benefits include:

  • Increased Versatility: Attachments allow the crane to perform a wide range of tasks, such as lifting, grabbing, drilling, and handling materials.
  • Time and Cost Savings: With the right attachment, you can eliminate the need for additional equipment, saving both time and money.
  • Improved Safety: Specialized attachments can enhance safety by providing better control, stability, and precision during operations.
  • Enhanced Productivity: Attachments enable the crane to handle diverse materials and perform multiple functions, boosting overall productivity on the job site.


Common Types of Knuckle Boom Crane Attachments

Various types of knuckle boom crane attachments are available in the market, each designed for specific applications. Let’s explore some of the most common ones:


Hydraulic Grapples

Hydraulic grapples are popular attachments that enable the crane to grip and lift different materials, including logs, rocks, and debris. These grapples have hydraulic cylinders that provide a strong and secure grip, ensuring efficient material handling.



Augers are attachments used for drilling holes in the ground. They are commonly used in construction, landscaping, and foundation work. Auger attachments for knuckle boom cranes are available in various sizes and can be equipped with different types of drill bits, allowing for versatile hole-drilling capabilities.


Clamshell Buckets

Clamshell buckets are ideal for handling loose materials like sand, gravel, and soil. These attachments consist of two hinged buckets that open and close, allowing efficient material scooping and dumping. Clamshell buckets are commonly used in excavation, dredging, and waste management applications.


Material Handlers

Material handlers, also known as grapple saws, combine the functions of a hydraulic grapple and a chainsaw. These attachments are specifically designed for tree removal and forestry applications. Material handlers enable operators to cut and handle trees efficiently, improving productivity in the forestry industry.


Man Baskets

Man baskets, also referred to as personnel baskets or work platforms, are attachments that provide a safe elevated working platform for personnel. These baskets are commonly used for tasks such as maintenance, inspections, and repairs at height. Man baskets equipped with safety features ensure the well-being of workers while working at elevated positions.


Factors to Consider when Choosing Attachments

When selecting knuckle boom crane attachments, it is important to consider several factors to ensure optimal performance and safety. Here are some key considerations:



Ensure that the attachment is compatible with your knuckle boom crane’s specifications, including lifting capacity, reach, and hydraulic system requirements.


Weight Capacity

Consider the weight capacity of the attachment to ensure it can handle the materials you need to lift or handle. Exceeding the weight capacity can lead to accidents and crane instability.


Durability and Maintenance

Choose attachments made from high-quality materials to ensure durability and longevity. Additionally, consider the maintenance requirements and availability of spare parts for the attachments.



Select attachments that offer versatility and can be used for multiple applications. Versatile attachments maximize the utility of your knuckle boom crane and provide a higher return on investment.


How to Properly Attach and Use Knuckle Boom Crane Attachments

Proper attachment and usage of knuckle boom crane attachments are crucial for safe and efficient operations. Follow these guidelines for optimal performance:


Safety Precautions

Prioritize safety by ensuring all operators are adequately trained in using the attachments and following safety protocols. Conduct regular inspections and maintenance to identify any potential issues before operating the crane.


Proper Installation

Follow the manufacturer’s instructions for attaching the specific type of attachment you are using. Incorrect installation can lead to equipment failure or accidents during operation.


Operating Guidelines

Adhere to the recommended operating guidelines provided by the attachment manufacturer. Follow load capacity limits, operational restrictions, and any specific instructions for the attachment’s proper functioning.



Knuckle boom crane attachments have revolutionized the construction and heavy machinery industry. These versatile tools provide increased functionality, safety, and productivity on job sites. By choosing the right attachments and following proper installation and usage guidelines, you can maximize the potential of your knuckle boom crane, making your job easier and more efficient.

In conclusion, knuckle boom crane attachments are invaluable tools that enhance the functionality and efficiency of these cranes. By considering the various types of attachments available, selecting the right ones for your specific needs, and following proper installation and usage guidelines, you can optimize your job site operations and complete tasks with ease and precision.
