Loading... Please wait...Hydraulic thumbs for excavators come in two basic styles - universal style with its own main pin and a weld-on base plate, or a shared-pin style thumb. Hydraulic thumbs require a dedicated two-way hydraulic circuit routed up the stick with pressure set approximately 70% of bucket curl pressure so the bucket will be able to overpower the thumb versus the opposite. The universal style advantage is ease of mounting and a greatly reduced risk of pin failures.
