Electric vibratory hammer

Electric vibratory hammer

Yong’an electric vibratory hammer mainly consists of 14 models, with eccentric momentum ranging from 287 Nm to 4328 Nm, and driving force from 380 Kn to 4370 Kn. This series vibratory hammer is equipped with shock-proof motor, German-imported bearing, making it capable of working for a longer time with no trouble.

 With strong technical support, the newly-developed DZ and DZJ series models, such as DZJ-400, DZJ=480 and DZJ-600, have been successfully put into Chinese market, further increasing our market share and brand recognition.

 What’s worth to mention, our vibratory hammers were not only widely applied in Chinese market, but also in more than 50 oversea markets, such as Japan, Korea, Indonesia, Malaysia, Vietnam, Philippines, Australia, Iran, etc.

Shock-proof motor
Shock-proof motor can work under high temperature up to 95℃, permit short-time overloading and has high starting torque. Wedge-shaped belt of high-strength is adopted.

Bearing
The bearings required will receive impact load, radial acceleration, high limit speed and other additional load. Use German FAG bearing to increase load capacity to more than 18% and prolong liftspan to more than 70%.

Production technology
Premier welding process complies with national standard and is inspected by Ultrasonic-wave. Bottom of the gear box is reinforced to minimize the possibility of damage.

Noise-proof design
Install rubber pad on top and bottom of the springs to realize buffer action and absorb noise. Steel pad is added on spring bottom to reduce noise.

Bearing ring design
Specially-designed bearing ring with three layers to withstand intense vibration and avoid cracking during operation, much more superior than traditional embedded design.

Oil precipitation design
Foreign matters may fall into the box accidentally, and oil precipitation system is designed to prevent these matters and oil stain from doing harm to gear and bearing.

Pre-cast concrete pile
Vibratory hammer, with corresponding clamps, can be used for various types of piles, such as pre-cast concrete pile, steel pile, cast-in-place concrete pile, concrete expansion pile, lime pile, san pile and gravel pile, etc.

Cofferdam
Vibratory hammer can be used to drive sheet pile to build the coffer wall. It is highly-efficient to push and extract sheet piles.

Trestle project and offshore working platform
Vibratory hammer to drive sheet pile or casing pile to build working passage and platform. It is easy for installation and removal.

Single pile and group piles foundation for offshore wind mill
It is efficient to use vibratory hammer to drive piles into the sea, which is easy for adjustment and environmental friendly.
