Amulet PowerClamp Hydraulic Thumb
Rugged Hydraulic Thumb for Maximum Excavator Versatility
The Amulet PowerClamp Hydraulic Thumb delivers superior performance across demanding applications, from demolition and land clearing to scrap handling and logging. Designed with heavy-duty cushioned hydraulic cylinders, serrated teeth, and reinforced gussets, the PowerClamp turns your excavator into a true multi-tool, able to grasp, lift, and manipulate materials with precision and power.
Available in 140° non-linkage or 180° progressive linkage configurations, the PowerClamp adapts to a wide range of excavators and coupler setups. When not in use, the clamp retracts tightly against the dipper, maintaining a streamlined profile. Built with high-strength alloy steel, hardened pins, and durable bushings, it's engineered for long service life under the most challenging conditions.
