Medium Electric Vibratory Hammer

　　 The medium electric vibratory hammer adopts resonance theory in designing. It is composed of hammer, clamp and power control box. There are different types of electric vibrating hammers according to the motor power, such as DZJ120, DZJ135, DZJ150 and DZJ180 medium vibratory hammers. The electric motor provides energy for the machine and works as key components.

1. Pre-Made Concrete Pile
With custom designed concrete clamp, medium 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 medium electric vibratory hammer to drive casing pile into the sea, environmentally friendly and easy to adjust.
1. Medium vibratory hammers are characterized by great centrifugal force, high frequency and strong penetrating power to hard soil.
2. These vibrating hammers are allocated with vibration dampers which are heavy. While pile driving, the large storage energy from the coil spring can improve the efficiency of hammering. When pile pulling, good damping effect can be achieved and the pile frame can be well protected as well.

If clients want to purchase the right medium electric vibratory hammers, some parameters should be paid attention to, such as the centrifugal force, amplitude and eccentric moment. In addition, the power of motor and the tonnage of crane, etc. are the factors that affect the clients' choice.

1. Electromotor of Medium Electric Vibratory Hammer
(1) Please consult electromotor instructions.
(2) Worn-out wires from connecting box should be wrapped with insulating tape and then be wrapped up with PVC tape. Seriously damaged wires should be replaced.
(3) Users should fasten the loose screw and replace the broken one so as not to damage the electromotor.
(4) Refill the main motor bearings with oil.
(5) If the temperature exceeds the allowable value, these vibrating hammers should stop. After troubleshoot, the electric vibratory hammers can work again.
2. Medium Electric Vibratory Hammer Host
(1) The tank should be erect when it is filled with oil and the refilling oil shouldn't be too much. It is appropriate when the refilling oil reaches the red point of the oil level indicator.
(2) When filling the tank, (after 40 hours for the first refilling and 300 hours for afterwards refilling) detach the drain plug at the bottom of the tank in order to let out the original oil. And then open the flank, get rid of the greasy dirt, dust and left powder of metals and screw up the drain plug, add fresh oil into the tank.
(3) Varieties of screws and nuts should be checked as often as possible. The loose ones should be fastened. And the broken ones should be replaced.
1. Shatter-Proof Electromotor
The electromotor is of high acceleration. And it has high allowable temperature (as high as 95 degree centigrade). Besides, these electric vibratory hammers make use of high tenacity v-belt.
2. Bearings
The electric medium vibratory hammers adopt X-LIFE high quality series bearings of brand FAG from Schaeffer Group in Germany. X-LIFE indicates that this series of bearings can undertake more load capacity and the working life can be prolonged.
3. Product Process
The whole welding process of the electric vibrating hammers conforms to national level welding standards. This process utilizes ultrasonic flaw detection. Besides, all round of the bottom half makes use of wrap angle. And the strengthening rid can efficiently reduce the stress of the tank. When working, the damage to the tank can be reduced to the minimum and the working life of electric vibratory hammer is prolonged.
4. Playback Design
First, the up and down springs are allocated with sheet rubbers which features buffer effect and can absorb certain working noise. Second, sound insulation plate is also added 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 medium electric vibratory hammer adopts the most advanced cutting technology for bearing collars, so such bearing collars are not easy to result in cracks and the whole equipment can work stably, and at the same time, this design guarantees the service life of the electric vibrating hammers. 1. Operation
(1) Turn on the power switch of medium electric vibratory hammer.
(2) Open the switch of control box .
(3) Start electric vibrating hammer.
(4) Press the “Start” button of the vibratory hammers.
(5) If it needs stopping, just press the “Stop” button.
(6) After completion of piling, turn off the general switch on the control box and the power switch.
2. Attention
(1) The worn-out or broken slinging steel wires should be replaced immediately in case medium electric vibratory hammer falls off.
(2) The operating staff must be trained before they start working. Besides, they should be familiar with the functions and performances of the equipments, especially the operation methods.
(3) The control box must be connected to the ground.
(4) Nobody is allowed to stand under medium electric vibratory hammers.
(5) When it is time for rest, the switch on the control box, together with the switch on the switch board which is closest to the power source, should be turned off.
(6) It is not suitable to start up the electric vibrating hammers in bad weather. Under this condition, vibratory hammers should be kept properly. If they are exposed outdoors, the medium electric vibrating hammers should be covered with plastic cloth so as to avoid being splashed wet.
(7) The maximum voltage is 380V (1±5%), or the motor will be burnt out.
(8) The medium electric vibratory hammers should be stopped when abnormal noise appears. Then check and fasten the loose screws, motor bearings and synchromesh gears so as to remove the stoppage.
(9) Auxiliary steel wire ropes should be used to connect the pile pipe and hammer or chuck when driving or pulling pile without materials.
(10) When the pile falls to the specified level, the main motor should stop. The pile cannot be loosened until the main motor completely stops (refer to the hydraulic clamp condition). If adjustment is needed, cut off the power source. 1. Different medium electric vibratory hammers are provided according to actual constructions.
