Vibro Hammers: The Essential Tool for Modern Pile Driving

Table of Contents

Vibro hammers is a comstruction equipment. It’s widely used in the piling industry. This article will describe the working principle, application, safety, and importance of vibratory hammers in foundation construction.

Vibratory drivers types include: excavator mounted vibro hammer, side grip vibro hammer, hydraulic vibro hammer, Sheet pile vibro hammer.

What Is a Vibro Hammers?

A vibro pile hammer is a tool used to drive piles into the ground. A pile is a long column made of steel or concrete (usually wood). These piles provide support for infrastructure projects such as buildings, cofferdams, bridges, etc.

Unlike a diesel impact hammer, a vibratory hammer uses vibration to reduce the friction between the pile and the ground. This method reduces noise and disturbance when driving piles. It is also suitable for areas with soft soil.

How Does a Vibro Hammers Work?

The heart of a vibratory pile hammer is an eccentric weight. These weights rotate at high speeds in the center of the hammer, creating vertical vibrations.

The offset of the weights creates an eccentric moment, which is necessary for the desired amplitude of vibration.

As the weights rotate, centrifugal force is generated. This centrifugal force, combined with the weight of the hammer, pushes the pile downward.

A hydraulic motor provides the power. A hydraulic power pack provides the energy, and a hydraulic clamp holds the pile in place during the driving process.

Why Use Vibratory Hammers

Traditional diesel pile drivers rely on impact force. The huge impact road generates noise and causes noticeable ground vibration.

Vibro hammers are very suitable for urban or residential environments because of their low noise.
The reduced friction of vibratory hammers can improve the efficiency of pile driving or pulling.
Vertical vibrations cause less displacement of the soil, resulting in a more stable and intact structure around the environment.

The Importance of Hydraulic Clamps

The piles are fixed by hydraulic clamps. 2 clamps press on the pile so that the pile is firmly fixed when driving the pile. This prevents the pile from slipping and improves site safety.

At the same time, different types of piles can be carried, such as sheet piles and casing.

Can Vibro Hammers Be Mounted on Excavators?

Vibro hammers can certainly be mounted on excavators. The excavator arm is equipped with a set of one-way hammers, which allows for mobility and flexibility.

Utilizing the hydraulic power system of the excavator, the excavator has hydraulic power AC units to provide power. No need to use a separate power pack.

Excavator mounted vibro hammers are suitable for small spaces. Especially for projects where traditional cranes are not suitable.

The Significance of Variable Moment Vibros

Variable moment vibros are advanced types of vibratory hammers.:

  • Reduced Vibrations: Minimize vibrations during start-up and shut-down, protecting nearby structures.
  • Enhanced Control: Operators can adjust vibrations based on soil conditions.
  • Environmentally Friendly: Great for sensitive environments such as offshore wind farms or urban areas.

Vibro Hammer Applications in Pile Driving

Vibratory hammers play a pivotal role offshore:

  • Bridge Construction: For bridge foundations, vibro hammers are used to install piles that support the bridge structures.
  • building: Vibro hammer used for foundation installation during urban house construction
  • More fields: Vibro hammers can also be used for structural foundation construction of cofferdams, offshore engineering, solar energy and other projects.

Vibro Hammer Rentals: What You Need to Know

Choosing the Right Vibratory Hammer for Your Project

Consider the following when selecting a hammer:

  • Soil Conditions: Understanding the soil conditions helps in choosing the appropriate amplitude and frequency.
  • Pile Type: Different hammers suit different piles, whether sheet pilescasings, or wooden piles.
  • Project Scope: Larger projects might require heavy-duty hammers with higher eccentric moments.
