Crusher bucket or demolition pulverizer?
These excavator attachments serve different workflows. A crusher bucket loads material and reduces it inside its crushing chamber, so a useful listing should identify the recommended carrier, inlet dimensions, output-size adjustment and hydraulic requirements. A demolition or bulk pulverizer grips material between a fixed and a moving jaw. Depending on its design, it can be intended for primary demolition or for secondary reduction and separation of reinforcement. Establish the material, work stage and handling method before comparing models.
Specifications to compare
Carrier compatibility: confirm the exact carrier model and configuration, recommended weight class, attachment weight, mounting interface and quick-coupler compatibility. A broad excavator tonnage range does not establish complete fit.
Hydraulic requirements: compare the required oil pressure and flow with the carrier's available circuit. A rotating pulverizer may publish separate requirements for jaw operation and rotation.
Crusher-bucket data: check inlet dimensions, service weight, output-size adjustment range and any capacity figure together with the material and test conditions to which it applies.
Pulverizer data: compare jaw opening, service weight, crushing force at its stated measurement point, cutter-blade length where fitted, and the availability and specifications of rotation.
Application: distinguish in-bucket processing of inert material from primary demolition and secondary concrete reduction. Reinforced concrete, asphalt, rock and mixed rubble can call for different tool configurations and wear parts.
What to inspect on a used attachment
Ask for the identification plate, model and serial number, operating documentation and hydraulic data. Inspect the body, mounting, pins, bushes, teeth, crushing plates or jaws, and any visible repair work. On a hydraulic attachment, examine cylinders, hoses, connectors and leakage; on a rotating model, also verify rotator operation. Acceptable wear limits must be checked against the documentation for the specific model.
Buyer FAQ
Do a crusher bucket and a pulverizer perform the same task?
No. A crusher bucket loads and processes loose material in its chamber, while a pulverizer grips an element between its jaws. The choice depends on whether material is handled as feed or reduced during demolition or secondary processing.
Is excavator weight enough to confirm compatibility?
No. The mounting interface, attachment mass and geometry, required oil pressure and flow, any rotation circuit, and the limits specified for the particular carrier and tool must also be checked.
What information should a listing include?
Useful details include attachment type, make, model and serial number, compatible carriers, mounting, weight, hydraulic requirements, jaw opening or chamber dimensions, output adjustment, crushing force with its measurement point, rotation, included equipment, documentation and photographs of wear.
