Hydraulic Vibro Hammer

Q: How can I select BRUCE Vibratory hammer to be optimized for the job ? I will need a 20 meters of driving depth for its upcoming project.
A: Let us assume that the total weight of your sheet piles are 3.5 tons and soil conditions on job site is considered as medium dense soil, we gladly recommend you BRUCE SGV-300 Vibratory hammer specified with 96 tons of centrifugal force. You may also visit our website at our website to find it out at Vibratory hammer catalogues.
Q: What type of Elastomers does your Vibratory hammers use, as far as I have known, it’s very important when driving and extracting a Vibratory hammer?
A: Yes, you’re right ! the Elastomer Rubbers make a very important role either absorbing the shocks deliver to the booms of base machines and when driving or extracting.
We are using two different types of Elastomer Rubbers in size and approximately, each of elastomer has more than 2 tons of maximum shear load. Additionally, A small safety bars fitted inside of the suppressor to protect the elastomers from falling down because of excessive crane pull driving or extractions.
Q: How should I grease BRUCE Vibratory hammer, how much grease should I use, and what type of lubricant is required?
A: All new power packs from BRUCE are delivered with Total Equivix ZS 46 (ISO, VG 46) hydraulic oil. Up on customer demand we can deliver any type and brand of hydraulic oil.
For the gear oil for a gear box, the level is easily read through the level gage on the center bottom side of the gear box. Under normal conditions and temperatures, the level should be in the middle of the gage.
Due to high operating temperatures, the most preferred lubrication oil is a synthetic lubricant. They have good oxidation stability and also provide considerably longer service life than natural lubricants.
The gear is used SHINSEGAE POWERQUIP INDUSTRIAL CO.,LTD. SHC 630 or 632 for splash lubrication. If gear oil looks black or milky color then drain the gear oil through the drain plug on the bottom of gear box and add new gear oil.

Q: What type of BRUCE Excavator mounted Vibratory hammer can you recommend to apply for my Excavator, mine is HITACHI EX200W?
A: We gladly recommend you BRUCE SGV-40 Excavator mounted Vibratory hammer.
This is that the BRUCE Excavator mounted Vibratory hammer can be divided into three different models according to its capacity of each Excavator can exhibit.
SGV-40, for example, is designed and fabricated to attach to an Excavator ranging from 20 tons to 30 tons of Excavators.
SGV-60, on the while, can be adopted to an Excavator from 30 tons to 40 tons.
SGV-80E, the biggest one among three of them, can be recommended for an Excavator ranging from 40 tons above for a proper work performances.
Q: What do I need to prepare for my Excavator, HITACHI EX200W to attach BRUCE Excavator mounted Vibratory hammer in a view of hydraulic or electrically?
A: The customer may, more than anything else, need to check to see if your Excavator has Breakers lines, which one is pressure line and the other is return line.
This is because the BRUCE Excavator mounted Vibratory hammer is attached and can be activated through these lines, we think other brands will be the same way.
The next step you need to focus on the Excavator is that you may need to check what type of your foot pedal is connected, hydraulically or electrically?
This is because that electrical connections provided by BRUCE will be a bit differ from hydraulic and electrical type of foot pedal to supply a proper oil flow.
Q: What is featured of your Vibratory hammers?
A: Our website at vibratory-hammers.html will kindly show you to have a quick look about what BRUCE Vibratory hammers are featured including base of carriers, main components and comprehensive operating tables.
We have two different types of Vibratory hammers divided into based on base of carriers which are Crane suspended type and Excavator mounted type that the customer both can have a choice depends on piling job plan or current situation given to the customers.
Q: How can I select the right Vibratory hammers?
A: To select the right vibratory hammer for a given job, some general rules such as soil condition, force of vibratory hammer, weight of pile, weight of hammer and type of pile are recommended.
Speaking of soil condition, more than anything else, vibrating a pile job in bigger stones or rock is definitely impossible to vibrate.
Q: What are benefits of Vibratory hammers?
A: Vibratory hammers are effective in a variety of different types of soil, including clay,
sand, and granular.
Vibratory hammers can also be modified for use underwater.
Vibratory hammers are very large and used in the industrial setting.
There are many benefits to the use of vibratory hammers.
A vibratory hammer requires less force to drive a pile.
Compared to other hammers that would be used in the same situation, vibratory hammers are relatively quiet.
Vibratory hammers are often chosen when construction work is conducted in an urban area where the noise of a traditional pile hammer would be a problem.
Vibratory hammers also make a good choice when the pile is located in an area without sufficient clearance to accommodate a traditional pile driver.
Q: How are Vibratory hammers installed?
A: The vibratory hammer is placed over the pile with the help of a piece of large equipment, such as a cranes or excavators. The vibratory hammer is then attached to the pile through a series of clamps. A vibratory hammer mounted on the crane is run by a power pack featured diesel engines hydraulic pumps and theoretical capacity to operate the vibratory hammer with connected with hydraulic hoses. If the vibratory hammer is put in place with an excavator, the hammer can run off the excavator's engine.
Q: What is Vibratory hammer?
A: A vibratory hammer is a kind of pile driver that specialized piece of equipment that uses vibration to change the soil formations so that the hammer can drive into the ground.
A vibratory hammer makes quick work of hammering into heavy or hard piles, and allows for an increase of efficiency on the jobsite. Vibratory hammers are used to drive in piles as well extract them.
There are three components to a vibratory hammer, the suppressor, gear box and the clamp.
The suppressor ass’y is mounted on the top of the gear box to isolate vibration to the crane.
It contains elastomer rubbers that dampen the vibration reaching the boom or crane.
The gear box has eccentric weights that rotate in a vertical plane to create vibration.
The hydraulic motors mounted on the gear box will drive the eccentric weights.
The motors and eccentric weights are connected to make proper synchronization.
Only vertical vibration is created in it as the paired eccentrics cancel horizont...
