mainly used for earthwork and asphalt applications. New construction and repair work for medium and small scale construction projects, on parking lots, sidewalks, cycle paths, playing fields and sports grounds as well as rolling of joints in road construction.
6~10t large vibratory roller with relatively high pressure and solid capacity should be used for national trunk roads and special roads for automobiles. Road Rollers,Vibrating Road Roller,Mini Road Roller,Drum Road Roller Shandong Luteng Building Equipment Co., Ltd. , http://www.lutengmachinery.com
Designed for two surgeons
CE & US FDA approved
Top Grade Quality:
Optics are Made in Germany, same Optics as Carl Zeiss Operation Microscopes
Available for digital /video recording during surgery
It can be upgrade to digital by attaching a video recording system: beam splitter, video adapter, video camera, imaging capture card and professional software.
and can use surgery trolley to save zoom in operating zoom
Aspherics and BIOM added on objective could meet the demands of vitreo-retinal operations.Â

For the highway below grade 3, or not often compaction work, it is best to equip with about 2t mobile flexible vibration roller.
2. For the cement concrete pavement, the series vibration roller driven by tire can be used;
3. For asphalt concrete pavement, full-drive vibratory roller should be selected;
4. For the bottom layer of high-grade road subgrade, it is better to choose tire roller or tire driving vibration roller for compaction to obtain uniform compaction;
5. When repairing the road surface, the static action roller can be used.
Iv. Selection of pressed materials according to the type:
1. For rock filling compaction, large tonnage roller should be selected to make large block displacement;
2 for clay compaction, it is best to use convex block ramming roller;
3. For the compaction of the mixture, it is better to choose vibratory roller, so as to mix the size of the particles evenly;
4. Heavy vibratory roller should be used for slow rolling for deep compaction, while static action roller should be used for shallow compaction.
Operation Microscope for Ophthalmology
Model: SOM-2000E
Zoom Main microscope(4.6-27x) with 3 steps Assistant MicroscopeÂ
Characteristics:
Electromagnetic lock and balance technology ensure the easy operation and stable orientation.
Cold light source is bright and even enough, which does no harm to tissues.
Germany imported Schott optics and Apochromatic technology ensure clear field of view and high resolutions.
The equipment is applied not only for ophthalmic operation, but also for neurosurgical, ENT, Cardio-Thoracic Surgical operations, etc.
