USVI PRODUCTS
(1) Rubber Rail Crossing Plate

Rubber rail crossing plate is a proprietary product designed, developed and produced by USVI which used in level crossing of railway and road. It is widely used in railway, subway, ports, platform, steel mill, goods yard, locomotive terminal and other railway level crossings with advantages of safe, stabilization, utility and convenience.
(2) ZTG Spring Vibration Isolators
The ZTG spring vibration isolators are made by high quality spring steel, providing enough high vibration isolation efficiency with low system natural frequency. The high quality rubber pad in the isolator can significantly improve the isolation efficiency for high frequency and can effectively reduce the transmission of solid-borne sound.It’s mainly applied to vibration isolation engineering of fans, pump, diesel motor, air compressor, cooling tower, air condition unit, light forging hammer and precision machine etc.,.
(3) Large-load damping-spring isolator
This isolator is efficiently worked for vibration isolation for heavy machines, such as machine tool, coal pulverizer, coal breaker, shock facility, forging hammers, which is large and heavy and can produce big impulse on the foundation.
(4) DJ rubber vibration isolator units
DJ rubber vibration isolator units are of shearing compression when the load is put on it. The units can be used to reduce vibration of fans、 air-compressors、pumps、diesel motors and mechanical equipment with low rotate speed.
(5) ZA rubber vibration isolator units
ZA rubber vibration isolator units are of shearing compression when the load is put on it. The units can be used to reduce vibration of fans、 air-compressors、pumps、diesel motors 、forging hammers and punches.
(6) JM isolating vibration pad unitsThe units are used to isolate vibration of all kinds of recording studios, broadcasting studios, studios, acoustic laboratory, odium, multi-function hall etc., and also are used to reduce vibration induced by vertical excited power.
(7) GD rubber isolating vibration pad units
The units are widely used and are called as muli-function. They are composed by four different diameters、different height bulges and the area of the every bulge is 1cm
2 . Many experiments proved that the pads absorb vibration energy and reduce amplitude of vibration.
(8) TDI hanging rubber vibration isolator (elastic hanger) units
The units can be used to reduce vibration that equipment and pipes transfer to floors and walls. This units are made up of compressing rubber vibration isolators and frames.
(9) TDIII hanging spring vibration isolator (elastic hanger)
The units can be used to reduce vibration that equipment and pipes transfer to floors and walls and can be used to isolate vibration for exact instrument.
(10) Sound Measurement Instruments
ASV 5910 noise dosimeterModel ASV 5910 noise dosimeter is used for personal noise exposure measurements in the work place. With attractive design, the ASV 5910 is mini-sized and easy to operate. It adopts modular design which makes ASV 5910 multifunctional.
