The electric boom machine is a small flat rod body that can be lifted and lowered parallel to the platform. Used for hanging curtains, soft scenes, lighting fixtures, etc. The suspension rod generally travels from 0.5 meters below the top of the grille to about 1.5 meters on the stage surface. There are various driving forms of electric suspension rods, including single slot crane, four slot crane, large-diameter double enveloping crane, multi-point crane, etc. Various specifications of cranes can be customized according to customer needs. The large-diameter drum type is a new product of our company, which is installed neatly and aesthetically, ensuring that the suspension rod is always straight during operation, reliable braking of the motor, and limit protection of the main circuit

Stage boom is a frequently used machinery on stage. It is mainly used for hanging and lifting various curtains, lighting fixtures, scenery and other objects, reducing the labor intensity of workers and achieving twice the result with half the effort. The suspension pole is driven by electric winding, with multiple layers of winding and a braking motor, effectively ensuring the positioning accuracy of the lamp pole. Considering the deflection of the structure under rated load, the lamp post adopts a double circular tube truss structure, using two φ 50 pipes are welded into a beam type suspension rod, and the middle joint is lined with steel pipes. Finally, both are coated with two coats of anti rust paint, and the outer layer is sprayed with black paint. The design safety system of all structural components complies with relevant national standards. The steel wire rope is selected with 6NAT6 × 19+HF1770 to ensure that the safety factor of the steel wire rope meets the relevant national standards under maximum load and maximum acceleration. The scenery suspension rod shall be made of a single pole or a double round pipe truss rod (according to the user's requirements), and the pipe or frame shall be straight and without distortion or deformation. The pipe rod shall be made of high-quality welded pipes, but shall not be less than the following specifications: the outer diameter of the double round pipe truss rod is 48 ± 2mm, and the wall thickness is 2.5mm; Minimize the number of joints on the rod body as much as possible. If joints are needed, solid round rods should be used to fit with the pipe, and welded joints with beveled ends of the pipe should be used. The end of the suspended steel wire rope is adjusted using a separate adjustment device installed on the pole to make the pipe horizontal and evenly stressed. Pipe end: The pipe end and expansion pipe are equipped with permanent plastic caps with eye-catching colors. The surface of the pole is painted in dark black, and a nameplate is hung.
