Product Overview
A side-grip pile driver — also referred to as a side clamp vibro hammer — uses hydraulic clamping jaws to grab the side of a sheet pile, H-pile, or tubular section while an eccentric vibratory unit sends the element down into the ground or pulls it back out. The side-clamping layout keeps the overall attachment profile tight, making it especially handy for foundation work right next to standing structures, inside deep excavations, or beneath bridges and overhead power lines where headroom is scarce. Because the clamp engages from the side rather than from the top, the operator can get a better angle on the pile and start driving from a lower starting point than a standard top-grip hammer would permit.
TGEC offers three side-grip pile driver models that fit excavators from 15 to 50 tons, with centrifugal force ranging from 364 to 780 kN and operating weights between 2600 and 3600 kg. Each unit is built around a stout clamp frame, a high-torque hydraulic motor, and replaceable grip jaws that stand up to repeated clamping cycles on steel sheet piles and structural shapes. For jobs that don't require the side-clamp feature and need a more general-purpose vibratory hammer, the standard excavator vibratory pile driver line offers top-grip configurations across a broader carrier range. Both families fall under the larger excavator pile drivers umbrella.

How It Works
The side-grip pile driver hooks into the excavator's auxiliary hydraulic circuit, which feeds pressurized oil to a hydraulic motor that spins a pair of eccentric weights inside the vibratory housing. Those weights rotate in opposite directions, generating a high-frequency vertical vibration that travels through the clamp frame straight into the gripped pile. That vibration temporarily reduces friction along the pile shaft, letting the element sink under its own weight plus the mass of the attachment. The side clamp uses hydraulic cylinders to squeeze hardened grip jaws tight against the pile web or flange, holding it firmly through both driving and extraction. From the cab, the operator manages clamping force, vibration start/stop, and vertical positioning, while the boom and crowd functions keep the pile on track.
Application Scenarios
Sheet pile installation for cofferdams, retaining walls and flood protection structures in urban sites with limited overhead clearance.
Sheet pile extraction during temporary shoring removal and cofferdam decommissioning.
H-pile and steel beam driving for foundation underpinning and structural support in excavated trenches.
Tubular and pipe pile driving for marine bulkheads, quay walls and small waterfront structures.
Piling work adjacent to existing buildings where a top-grip hammer cannot swing into position.
Low-headroom piling under bridges, power lines, canopy slabs and inside building footprints.
Vertical and raked pile installation where side access provides better alignment control than top driving.
Remedial and replacement piling on congested foundation sites with restricted equipment access.
Installation & Mounting
The side-grip pile driver attaches to the excavator boom through either a standard pin-on bracket or a quick coupler adapter, depending on the carrier's setup. Before installation, confirm the excavator make and model, operating weight, pin-to-pin spacing, pin diameter, coupler type, and available auxiliary hydraulic flow and pressure. The attachment needs a dedicated auxiliary circuit for the vibratory motor and a separate circuit for the clamp cylinders on models with independent clamping. Our technical team checks compatibility and supplies the right mounting bracket, hose kit, and pressure settings for your specific excavator configuration.
Wear & Service
The main wear items on a side-grip pile driver are the grip jaw inserts, clamp pins and bushings, eccentric weight bearings, hydraulic motor, and high-pressure hydraulic hoses. Inspect the jaw inserts before each shift for wear, cracks, or loss of gripping surface, and swap them out when clamping performance drops off. Check clamp pins and bushings for play, grease all lube points per the schedule, and inspect hoses for abrasion, leaks, or cracking near the vibratory housing. Keep an ear on the hydraulic motor for unusual noise or overheating, and change hydraulic fluid and filters at the recommended intervals. Genuine replacement jaw sets, bearings, and seal kits are available for all TG-SG models.
