Introduction:

The resonance-free vibro hammer is a very efficient and environmentally friendly piling equipment, which reduces the impact and noise of vibration on surrounding buildings and protect the safety of the building. The vibration control of the resonance-free vibro hammer is more precise, which can complete the compaction operation more efficiently and improve construction efficiency. It has strong adaptability to geological conditions and can adapt to various types of soil conditions. It is also suitable for many different types of piles to meet the construction needs of different projects.

To achieve true resonance-free, there are two prerequisites:

1. Adjustable eccentric moment

2. High frequency

Generally, when the speed of a vibratory hammer exceeds 2000rpm, its operating frequency greatly exceeds the natural frequency of the soil, so the damage to the surrounding soil is minimal.

	Heavy metal filled eccentric block Our eccentric blocks of major model hammers are filed with heavy metal, that can produce more eccentric moment and bigger centrifugal force at same frequency. So our vibratory hammers drive piles more efficiently.
	German FAG high speed bearing We adopts German FAG bearings, which have longer service life than ordinary bearing.This is key components to keep hammer working time.
	REXROTH hydraulic system Our all hydraulic pumps are from world top brand-Rexroth, which service life and performance stability are much better.
	Forced lubrication cooling system Forced lubrication system make gear parts of vibro hammer more fully lubricated and the temperature increase is steady.
	Build-in Oil circuit Hydraulic oil circuit is built in top cover of gear box, eliminating some hoses and avoiding damaging while working, thereby reduce failure rate. The structure of vibratory hammer is more compact.
	Embedded motor Our hydraulic motors are embedded or with external protective shell, reducing the damage chance of the motors due to collision during the operation, and keep vibratory hammers steady.
