Advantages of Thumb

18 To 25 Tone Hydraulic Bucket Thumb Grabs 1800mm

Save Time

Hydraulic thumbs allow the operator to adjust the angle of the thumb without leaving the cabin of the machine to move from task to task quickly. This is an attachment on any job site where precision and efficiency are key.

Improved Safety

By providing the operator with better control, hydraulic excavator thumbs contribute to enhanced job site safety. Minimize the risk of accidents like load slipping and unexpected falling with the sturdy construction and greater control

Handle More Materials

A hydraulic thumb can significantly increase the versatility and capability of your machine. You can manipulate a range of materials ranging from rocks and logs to pipes and debris that may not easily fit into the bucket otherwise.

Enhanced Operation Precision

Hydraulic power allows the operator to adjust the angle of the thumb with greater precision, thus providing greater control to grasp, transport, and handle materials. They can be used to shape trenches, create precise holes, and maintain a consistent depth, which is crucial for tasks like utility installation.

Application of Thumb

Handling Debris and Waste
Mini excavator and excavator thumb grabs excel in handling loose debris and waste materials, making them idea for demolition and construction clean-up operations. The thumb provides a firm grip on irregularly shaped objects, allowing for efficient moving, sorting and disposal.

Landscaping and Forestry
In landscaping and forestry applications, excavator thumb grabs are ideal for moving rocks, logs and large branches. Their ability to securely grasp objects of various sizes and shapes between the thumb and excavator attachment makes them perfect for clearing land and other landscaping tasks.

Scrap and Recycling Yards
Scrap yards and recycling centres benefit greatly from the use of thumb grabs on excavators. The thumb enables the operator to pick up, sort and move scrap metal and other recyclable materials with ease, improving productivity and safety on site.

Utility and Infrastructure
When working on utility and infrastructure projects, thumb grabs can assist in handling pipes, poles and other materials that require precise placement. They are particularly useful in trenching operations, where they can help position and secure materials in place.

Different Designs of Thumb

Hydraulic Quick Coupler Thumb
A hydraulic quick coupler thumb (or coupler thumb) works the same as a main pin setup, still mounting through the stick of the machine, but through the coupler, instead of the bucket. This means that you can change between buckets easily, and the thumb stays on the machine.

Hydraulic Stick Mounted Thumb
Another popular thumb design is a hydraulic stick mounted thumb. This style is completely independent of any coupler's or bucket's by being mounted completely on the excavator. Stick mounted thumbs require more welding when being installed as there has to be two pivot points welded to the machine. Most stick mounted thumbs that we supply come with a large single piece base plate that is welded to the stick.

Progressive Link Thumb
Perhaps the latest thumb design is the progressive link thumb. This setup uses an extra link in between the hydraulic cylinder and the thumb in order to achieve more rotation. Being able to rotate the thumb further, means that you can work closer to the cab with the stick more upright and still meet the bucket's cutting edge.
