expansion device for continuosly welded rails

The regions can be defined by long and short bars, in which microdevices span gaps between the longer bars, and the shorter bars measure less than 60% of such gaps.

The long bars and the support bars both have holes, wherein the ends of the steelwires are inserted into the holes.

A tipe of steelwire-hook web sheet comprises long bars, support bars and horizontal and vertical steelwires.

In order to add the strength of the frame and reduce the length of the horizontal steelwires, some long bars and support bars may be added in the frame.

Composition: 42 pieces (12 long bars, 18 short bars and 12 metal balls).

The long bars and support bars are fixed together and the horizontal and vertical steelwire are intercrossed each other to form a web sheet.

The twelve meter high poles open up like a blossom and seem to unblock the way.

Slang is a blending of the two words s(ecret) and lang(uage).

The receiver is made from formed sheet steel and consist of two parts - upper and lower.

Polychords (or bichords) are chords constructed of two or more triads.

When they obtain the red copper, they make it into bars a span and a half in length, some thin and others thick.

The numerical control milling machine can solve the problem of manufacturing long rail, and the structure of the manufactured long rail can meet the requirements of processing quality, speed and appearance.
