Upgrade Your Excavator with RSBM Hydraulic Thumb

Choosing the right excavator attachment can significantly improve on-site efficiency, and sometimes a small design improvement brings a big difference. Today, let’s introduce the upgraded RSBM Hydraulic Thumb, engineered to make daily operations easier and more efficient.

 

A Simple Problem That Matters in Real Work

 

Looking at the comparison images, you can clearly see the difference.

Traditional hydraulic thumbs need to be tied and secured with a rope when folded back. However, in real jobsite conditions, this can easily become a problem:

  • What if the rope is missing?

  • What if the operator is under time pressure?

  • What if the working environment makes tying difficult?

A small inconvenience—but repeated every day—quickly affects productivity.

New Upgrade: Built-In Hook for Fast Folding

 

The new RSBM hydraulic thumb solves this issue directly.

The upgraded model features an integrated hook, allowing the thumb to fold neatly inside the boom without any rope, tools, or additional securing steps.

This upgrade delivers:

  • Faster folding and deployment

  • Easier daily operation

  • No loose accessories to manage

  • Higher work efficiency

  • Better operation safety

A small structural improvement, but a big enhancement in user experience.

Built with Quality Materials and Professional Craftsmanship

 

Here is one of our recently completed models—
Weld-on hydraulic thumb for ZX55, manufactured with:

  • Durable and wear-resistant steel

  • Strong structural reinforcement

  • Smooth and precise welding

  • A low-profile design for long service life

Every thumb is made to handle real, high-intensity jobsite environments.

Customer Feedback from the Field

 

Operators using the new design shared consistent positive feedback:

  • “Faster tool switching.”

  • “No extra parts to remember.”

  • “More convenient in narrow or complex working conditions.”

Practical improvement backed by real-world results.

Better Product, Same Price

 

Even with the design upgrade, the price remains the same.

No additional cost.
No extra charge.
Just better usability and higher value for our customers.
