Hydraulic Solar Photovoltaic Pile Driver Hammer Attachment Hydraulic for Excavator 20-30 T

The product name cites a model optimized for 20–30 ton excavators, but the specification sheet lists a broader suitability range of 8–55 tons. Compatibility depends on the specific mounting kit and excavator counterweight/boom capacity. Always confirm your excavator's hydraulic flow, pressure and lifting capacity with the supplier before purchase; adapters are often available to fit different carrier sizes.

Required working pressure is 200–330 bar and recommended oil flow is 100–300 L/min (depending on model and piling conditions). Verify your excavator's max hydraulic flow and pressure and ensure the hydraulic supply and return lines, hoses and couplings meet these ratings.

Listed gross weight is approximately 2700 kg and main body weight is shown as 1.2–2.6 tons depending on configuration. Because of this mass and the need to align hydraulic lines, a crane or heavy-lift equipment is typically required for safe installation.

Key internal specs include an eccentric moment of 3.2–11 Nm, rotation speed around 2600 rpm and centrifugal force in the range of 24–81 kN. These values will influence impact energy and piling effectiveness and can vary by exact model and configuration.

Piling speed depends on soil type, pile dimensions, hammer settings and excavator hydraulic capacity. The attachment is designed for fast piling compared with conventional methods, but exact m/min rates vary widely; consult your supplier for field trial data with similar soil and pile sizes.

Common applications include driving solar panel piles (photovoltaic racking), construction foundations, fencing posts, utility poles and environmentally sensitive installations where minimal soil disturbance is desired. It works with commonly used steel tubular, H-piles and driven posts—confirm compatibility for specific pile diameters and wall thicknesses.

Core components include the hydraulic motor/hammer assembly, eccentric weights, clamps and extension boom sections. Typical wear parts are seals, bushings, striker/impact elements, hydraulic valves and mounting hardware. Keep a stock of seals and common wear items on-site for quicker turnaround.

The unit mounts to the excavator arm via a model-specific bracket or quick coupler adapter. Suppliers commonly offer clamp sizes and extension booms (weights vary by model) to match pile diameters and working reach. Provide your excavator make/model and boom geometry to ensure the correct mounting kit is supplied.

Ensure the excavator is rated to safely carry the attachment and loads; use a qualified operator; secure hydraulic lines and check for leaks; maintain proper standoff distances; follow local noise and vibration regulations; wear PPE; and never operate if any mounting bolts, hoses or safety devices are compromised. Use tag lines when handling piles and follow the manufacturer's safety manual.

Regular maintenance includes checking and replacing hydraulic oil and filters per the excavator and attachment schedules, inspecting seals and hoses for wear, greasing bearings where applicable, tightening fasteners, and inspecting the eccentric mechanism and striker for wear. Follow the manufacturer's maintenance intervals and keep a maintenance log.

Pile driving generates significant noise and ground vibration. Mitigation measures include scheduling work during acceptable hours, using noise barriers where appropriate, applying vibration monitoring for sensitive sites, and ensuring the excavator is used within recommended settings to minimize excess impact energy. Operators should use hearing protection.

When ordering, provide your excavator make/model and boom specifications, the target pile type (diameter, wall thickness, material), expected pile lengths, required working reach, and your hydraulic system’s max flow and pressure. Also specify any preferred clamp or extension-boom configuration to ensure proper fit.

Contact the manufacturer or authorized dealer (brand listed as HOMIE in the spec sheet) for spare parts, service and warranty details. Provide the unit serial number and model code when requesting parts or support. Authorized dealers can also assist with installation, commissioning and operator training.
