Vibratory Hammer

Vibratory hammer, or pile driver,is an essential part and the main body of hydraulic vibratory hammer for foundation construction. It works in combination with power pack and clamps to finish piling. When used in pile frame, hydraulic vibratory hammer can drive cast-in-place concrete pile, lime pile and sand pile. And if equipped with hydraulic holder (hydraulic clamps), sheet pile hammer will be able to drive and extract steel casing pile, steel sheet pile, joist steel pile and concrete precast pile. It is the ideal pile driver for residence, factories, subways, highway, docks, airports and power plants. Meanwhile, hydraulic vibratory hammer can also be working underwater.

As showed in the table, YZ-70 sheet pile driver hammer has an eccentric moment of 23 kgm and a maximum line pull capacity of 400 kn. Besides, its rated centrifugal force is 650 kn, while the maximum centrifugal force can reach 845 kn. This model can be used with single or double clamp in driving steel casing piles, steel sheet piles and joist steel piles.

With 27-year experience in vibratory hammer manufacture, Yong'an has a skilled technical team who can design and manufacture the most appropriate hydraulic vibratory hammer according to customers' requirements. And they can help customers to shoot out the different problems during the using. All this contributes to its popularity and good reputation.

Suitable vibratory hammer should be selected according to the centrifugal force. As for clamp, double clamp is available. Or the company can customize for clients in line with actual need.

• Operation
  1. 1) The hydraulic vibratory hammer should be checked before starting.
  2. 2) To electrify control circuit and test solenoid valve.
  3. 3) Start diesel engine and make it operate at high speed.
  4. 4) An appropriate working mechanism of oil pump needs be selected.
  5. 5) Try to choose a proper piling model.
• Precautions
  1. 1) Frequent checks on pressure gage, diesel engine meter box and oil pump should be made when in operation. And if any abnormality is found, the service should be stopped promptly to find reasons and debug.
  2. 2) Vibratory hammer shall be halted and checked when the system is leaking or blowing oil.
  3. 3) The temperature of hydraulic oil should be less than 70 degrees. If it is too hot, close the machine and restart when the oil cools down. The system should be running without load for over 10 minutes when the environment temperature is less than 10 degrees and operate after the oil temperature is above 30 degrees.
  4. 4) When leakage of air happens during operation, operators should put a halt on the hammer to check whether the piston sealing element of the high pressure energy accumulator is damaged or not. Make a prompt replaconcrete if damages are found.
  5. 5) Energy accumulator can accept nothing but nitrogen. Oxygen or other fire gases should be prohibited in case of explosion.
  6. 6) Any operation of vibratory hammer should be within the maximum stroke and minimum stroke.
  7. 7) Oil needs to be kept clean and polluted oil is forbidden to use again.
  8. 8) New oil pump should be aired and fill oil in shell before use.
  9. 9) At beginning, operators can use small stroke to pile and after the pile penetrates the hard pan, enlarge the stroke. Otherwise, the vibratory hammer, especially the pallet will be damaged.
  10. 10) Operators should ensure that the system has released pressure before checking hydraulic system.
  11. 11) Remember to switch off battery pack when diesel engine stops working in case of discharging outwards.
  12. 12) Do not start diesel engine when it is at the highest speed. And if it can't work within 30 seconds, stop starting and restart 3 minuters later.
  13. 13) The capacity of storage battery should be no less than 200 Ah.

1. Hydraulic vibrator hammer should be cleaned frequently. Operators of each shift should clean vibratory hammer and power pack carefully.
2. Regular inspection on fasteners should be made. And every lubricating point needs lubricating according to lubrication requirements.
3. Frequent examination on water should be made to avoid rust.
