Hydraulic Thumb for Mini Excavator 800 kg - 1.8T

When a hydraulic thumb presses a load against the bucket's cutting edge, the nature of gripping changes. On a mini excavator from 800 kg to 1.8T, this component replaces manual retention in sorting, light skidding, and material handling operations. It comes complete with cylinder, pivot pin, and hydraulic hoses, covering basic mounting on the arm.

Function of a Hydraulic Thumb

This thumb holds a load against the bucket during movement or positioning. Its hydraulic control eliminates the need for the operator to leave the cab to secure a log, stone, or pile of brush. The cylinder stroke determines the opening and closing of the clamp; the machine's hydraulic flow controls the speed of movement.

Compatibility with 800 kg to 1.8-tonne Machines

This thumb fits chassis with an operating weight between 800 kg and 1,800 kg. Before installation, check the mounting hole spacing on the arm and the type of hydraulic hose connections. The auxiliary circuit pressure must match the supplied cylinder's specifications. Operators already using a hydraulic hedge trimmer for mini excavators know this rule: any hydraulic attachment requires strict matching to the machine's flow and pressure.

Common Jobsite Applications

The hydraulic thumb excels when handling mixed materials. It holds a log steady while a 64 cm hydraulic mulcher for 1T to 1.8-tonne mini excavators feeds nearby, or it stabilizes a stone block during rock placement. It also proves useful after stump removal or after using a 80 cm skeleton bucket for mini excavators, when oversize material must be moved without manual handling.
