Large Electric Vibratory Hammer

With the help of resonance theory, electric large vibratory hammer is designed for various foundation engineering construction and ground treatment, such as the construction of dwelling houses, workshops, metros, highway, quays, airports and power stations, etc. Its energy is from the electric motor. Electromotor works as its key component. This electric vibratory hammer can drive cast-in-place concrete pile, lime pile and sand pile. Matched with corresponding clip pile device, electric vibrating hammer is capable of driving and pulling a variety of steel piles and concrete pre-cast piles. DZJ200, DZJ240, DZJ300 and DZJ400 are typical types of electric vibratory hammers.

The large electric vibratory hammer is constituted by a hammer, a clamp and a power control box. (Clients can choose motor according to their actual needs.)

1. Yong'an electric vibratory hammer has characteristics of centrifugal force, high frequency and strong penetrating power to hard soil.
2. This large vibrating hammer is armed with vibration damper which is heavy. When pile driving, the large storage energy from the coil spring is capable of improving the efficiency of hammering. When pile pulling, ideal damping effect can be achieved and the pile frame can be well protected as well.

1. Pre-Made Concrete Pile
With custom designed concrete clamp, large electric vibratory hammer can be used for various types of pre-made concrete piles, cast-in-place concrete pile, concrete expanded bore pile, lime pile and stone column pile.
2. Cofferdam
Electric vibrating hammer is used to drive sheet pile to build the coffer wall. It is high efficiency to drive and pull sheet piles.
3. Trestle Work and Offshore Working Platform
Drive sheet pile or casing pile to build working passage and platform before build bridge, dork, port, etc. It is easy to build and easy to remove.
4. Wind Mill Single Pile and Group Pile
It is efficient to use large electric vibratory hammer to drive casing pile into the sea, environmentally friendly and easy to adjust.
1. Electromotor
(1) Please refer to the electromotor instructions.
(2) If the wire from connecting box is damaged, it should be wrapped with insulating tape and then be wrapped up with PVC tape. If the wire is serious damaged, it should be replaced.
(3) The screws on belt pulley pressing plate should be fastened. If they are damaged, the screws should be replaced.
(4) Fill the main motor bearings with oil.
(5) If the temperature rise in electric motors exceeds the allowable value, the machine should stop. After troubleshoot, the electric vibratory can work again.
2. Large Electric Vibratory Hammer Host
((1) When filling electric vibratory hammer, the tank should stand straight and the refilling oil needn't be too much. The refilling oil reaches the red point of the oil level indicator. Calcium base grease should be refilled between vertical axis and nylon bushing.
(2) (After 40 hours for the first refilling and 300 hours for afterward refilling) the drain plug at the bottom of the tank should be detached in order to let out the original oil. And then open the flank, remove the oil dirt, dust and powder of left metals and screw up the drain plug, renew the oil in the tank.
(3) Various kinds of screws and nuts should be checked and fastened and replaced when necessary. 1. Shatter-Proof Electromotor
The electromotor is of high acceleration. And the maximum temperature in its bearing can be as high as 95 degree centigrade. Besides, large electric vibratory hammer takes the advantage of high tenacity v-belt.
2. Bearings
This electric vibrating hammer adopts X-LIFE high quality series of bearings of brand FAG from Schaeffer Group in Germany. This series of bearings can undertake more load capacity. Therefore the working life is prolonged.
3. Product Process
The overall welding process of the large electric vibratory hammer is in accordance with national level welding standards. It makes use of ultrasonic flaw detection. Besides, the bottom half makes is dealt with wrap angle. When working, the tank damage can be reduced to the minimum and the working life of electric vibratory hammer is prolonged.
4. Playback Design
First, sheet rubbers are put under the base of the up and down springs. The sheet rubber has buffering effect and can absorb certain noise generated during the working process. Second, sound insulation plate is also added up to the bottom spring and this can effectively lower the working noise of the electric vibrating hammer.
5. Unique Bearing Collar Design
Compared with the traditional bearing collar, Yong'an large electric vibratory hammer adopts the most advanced cutting technology for bearing collars, so such bearing collars have on cracks and the whole equipment can work stably, and at the same time, this design guarantees the service life of the electric vibrating hammer.

After signing the contract, 30% deposit payment should be paid. And full payment should be paid before delivery.

The hammer and clamp adopt thin film packaging. The control cabinet and components can employ wooden case packing (according to clients' requirements).
