What is a long cantilever structure
A connecting member which is joined to the holder so as to be connected to the support by the engaging member and to adjust the height via the elevating means, the pivoting direction
A pivot is in the middle of a shaft seat to open a shaft groove, and the other side of a clip on both sides of the wing extension of the inside of each adjacent a tight ring, during which the shaft socket, and the other extension of the extension of the rod And a shaft is engaged with the support shaft so as to cohomard and tighten the shaft to seat so that the frame is rotatable;
A lifting device provided with an elastic body between an inner sleeve and telescopic rod and an outer drum connected with the inner sleeve so that the top opening and the top edge of the inner sleeve have a clamp ring, and the The outer drum is rotatable outside the inner sleeve so as to apply radial pressure to the clamp ring so as to cause the telescopic rod to be tightened or released so that the telescopic rod is movable at the top of the outer drum,
The definition of long cantilever structure has a prerequisite for seismic fortification, and similar to the large-span structure of the seismic specifications: 8,9 degrees when the large span and long cantilever structure and 9 degrees when the high-rise buildings should be calculated vertical earthquake effect. 8-degree span of more than 24 meters structure, 2-meter-long cantilever structure is a large span and long cantilever 9 degrees span greater than 18 meters structure, 1.5 m long cantilever structure is a large span and long cantilever
