Manual and Hydraulic
Thumbs
for Hydraulic Excavators
       
 
         

Gain a grapple without losing your bucket


  • A Dymax Thumb broadens the range of jobs your hydraulic excavator can handle and reduces wear and tear on buckets in special applications.
  • Use a Dymax Thumb for handling or loading trees, logs, pipe, rocks, irregular-shaped objects or debris without adding manpower or other equipment.
  • Much like the human thumb makes the hand uniquely productive, a Dymax Thumb makes a hydraulic excavator and bucket a uniquely effective tool in a multitude of jobs.
  • Dymax Thumbs are available in manual and hydraulic models, and with progressive links or without links.
  • Bucket size and the specifics of the application are elements to use in determining whether to use a two-, three- or four-tine thumb configuration.
  • These productive attachments are available for nearly all hydraulic excavators from the smallest minis to the largest full-size machines.
  • For more information on Dymax Thumbs or the full line of Dymax Custom Attachment Solutions, contact a Dymax sales representative at 1-800-530-5407.

 

Dymax Progressive Link Hydraulic Thumb. Special linkage gives Dymax Progressive Link Thumb up to 142° rotation.
Dymax Manual Thumb. The Dymax Manual Thumb features two working positions and a convenient storage position.
Dymax Non-Link Hydraulic Thumb. This thumb falls short of its more “progressive” cousin because of the “missing link.”

 

 


Dymax Thumbs for hydraulic excavators are available in several configurations for nearly all sizes of buckets:

  • Manual Thumb - Features a three-position setting, spaced 4” apart. Available in either a weld-on or pin-on style. Weld-on thumb has two mounting brackets that are welded to the underside of the stick. Pin-on style attaches to bucket pin.
  • Non-Link Hydraulic - This thumb provides the added productivity of hydraulically-driven movement. Offers 110-115° rotation. May be welded or pinned on.
  • Progressive Link Hydraulic - This is the most productive and flexible of the Dymax Thumbs. Pins to bucket pin and features an additional linkage that allows rotation of 140-142°.

Materials and specifications subject to change without notice.
