Wide one times in the middle of the Width at hanging beam body of the present invention two ends.
Compared with prior art, the present invention has following beneficial effect:
1, because the present invention connects into an integral body with two-thread screw with hanging beam and revolving body workpieces, make hanging beam and revolving body workpieces form position relationship with the cross centre line symmetry, two change gears of hanging beam are in the center of revolving body workpieces, like this, actv. has been controlled the centre-of gravity shift of revolving body workpieces when handling, solved the tilt problem in the handling process, realized fixing a point to put.
2, because the present invention has controlled the centre-of gravity shift of revolving body workpieces when handling, revolving body workpieces does not tilt, and steel rope is symmetrical, isometric, makes the stressed even of rope.
3, owing to all be provided with hanger at hanging beam horizontal surface and vertical surface, no matter revolving body workpieces is to put at level attitude or upright position.Overhead traveling crane can both be easy to by the level on the hanging beam body or vertical hanger, is suspended on the flange face of revolving body workpieces to install.
4, the width at the two ends of hanging beam of the present invention goes out one times than center field width, in two zones of this symmetry, two mounting holes corresponding with the gyro-rotor flange hole is arranged respectively, by strengthening the distance of two mounting holes, has guaranteed the even distribution that the beam body is stressed.
5, the present invention puts protecting sleeve at two-thread screw, protects on the one hand screw thread; On the other hand, avoid the local contact of hanging beam easily to produce shearing force.
