Frequently Asked Questions About OMS Vibro
OMS Vibro designs and manufactures equipment for vibratory pile driving, pile extraction and ground improvement applications. The main product categories include Vibratory Hammers, Hydraulic Clamps, Hydraulic Power Packs, Vibroflotation Equipment and Wick Drain Equipment. The complete equipment portfolio can be reviewed on the OMS Products page.
A vibratory hammer transfers vertical vibration to a pile through the clamping system. The vibration reduces resistance between the pile and the surrounding soil, helping the pile penetrate the ground or be extracted. The vibration is generated by rotating eccentric masses inside the vibration case. OMS offers different Vibratory Hammer configurations for different pile types, soil conditions and project requirements.
OMS vibratory hammer solutions include crane-suspended SVR Series machines, excavator-mounted OVR Series machines and excavator-mounted Side Grip systems. The portfolio also includes Normal Frequency and Variable Moment configurations, allowing the equipment concept to be selected according to project requirements, pile characteristics and working conditions.
Crane-suspended vibratory hammers are generally selected for applications involving heavier piles, greater driving depths or projects requiring higher driving and extraction capability. Excavator-mounted vibratory hammers provide greater mobility on the jobsite and are designed to operate through the excavator’s hydraulic system. Final equipment selection should consider soil conditions, pile properties, required depth and available carrier capacity.
OMS Variable Moment systems use a phase-shifter mechanism to control the relative position of the eccentric masses. During starting and stopping, the eccentric moment can be controlled to reduce vibration transmission associated with passing through resonance. This makes Variable Moment technology particularly relevant where vibration management around the jobsite is an important engineering consideration. Available solutions are included within the OMS Vibratory Hammers range.
Depending on the vibratory hammer configuration and hydraulic clamp selection, OMS equipment can be used with sheet piles, tube or casing piles, H-beams, I-beams and other compatible pile profiles. Correct clamp and vibro hammer selection is essential for transferring vibration and clamping force effectively to the pile.
OMS Side Grip Vibro Hammers are designed for handling, pitching, driving and extracting piles with an excavator. Their rotating and tilting arrangement provides operational flexibility in confined areas and locations with limited headroom. Depending on the gripping arrangement, the system can work with sheet piles, beams and tubular piles. The dedicated Side Grip Vibro Hammer page provides further technical information.
Vibratory hammer selection is an engineering process rather than a decision based on centrifugal force alone. Important parameters include soil conditions, driving or extraction depth, pile type, pile dimensions and weight, required installation method and the available crane or excavator. For excavator-mounted systems, hydraulic pressure, oil flow and excavator working weight must also be considered. OMS provides selection guidance and project-specific technical support.
OMS Hydraulic Clamps provide the mechanical and hydraulic connection between the vibratory hammer and the pile. OMS offers KCN Series clamps for tube piles, SCN Series clamps for sheet piles and ACN Series clamps for timber piles. Clamp selection depends on the pile geometry, vibratory hammer configuration and required clamping conditions.
An OMS Hydraulic Power Pack generates the hydraulic flow and pressure required by compatible hydraulic equipment. Power pack selection must match the hydraulic requirements of the connected equipment. OMS Power Packs are used with systems including crane-suspended vibratory hammers and OMS ground improvement equipment.
OMS OVR excavator-mounted vibratory hammers are designed to operate using the excavator’s hydraulic system. The excavator must therefore provide the required hydraulic flow and pressure for the selected vibro hammer, and its operating weight and hydraulic configuration must also be suitable. Project-specific compatibility should be confirmed before operation.
OMS Vibroflotation Equipment is designed for ground improvement applications involving vibro compaction and vibro replacement. OMS systems include top-feed and bottom-feed configurations. Depending on the ground improvement method, vibration is used either to densify suitable granular soils or to compact granular material used to form stone columns.
In top-feed applications, granular material is introduced from the ground surface as the vibroflot works through the treatment zone. In OMS bottom-feed systems, granular material is delivered toward the lower end of the vibroflotation system through the feeding arrangement while the stone column is constructed and compacted. The appropriate method depends on soil conditions, project requirements and equipment configuration.
The OMS Wick Drain Installation Machine is used for installing prefabricated vertical drains (PVD) in cohesive soils. The system installs the drain material into the soil using mandrel and hydraulically driven equipment, with vibratory assistance available when required. The purpose of the PVD system is to facilitate drainage and accelerate soil consolidation.
Yes. OMS vibroflotation systems can incorporate monitoring functions for ground improvement operations. Depending on the system configuration, parameters such as column depth, compaction values, column diameter and gravel fill volume can be monitored and recorded to support production control and project reporting.
OMS evaluates equipment configuration according to project requirements and offers project-specific engineering and custom manufacturing where required. Factors such as pile geometry, soil conditions, installation method, carrier configuration and hydraulic requirements should be reviewed before the final equipment configuration is defined.
