The electric boom can reduce the labor intensity of workers and achieve twice the result with half the effort. If the depth of a stage is 14 meters, we can set up 38 electric booms for it, including 24 scenery booms (including one front curtain), 14 spare booms [including 2 two-dimensional side light stands], one elevating movie screen stand, one lighting bridge, and one set of infinitely uniform telescopic screen machine.

Based on our years of experience with stage boom machinery, we believe that the products manufactured by Taizhou Yangtze River Film and Television Engineering Equipment Factory are stable, safe, and reliable, and have been adopted by hundreds of theaters. They utilize a worm gear reduction system, are made of tin bronze, have a low friction coefficient, and high transmission efficiency. They are equipped with anti-toppling protection and upper and lower limit protection. The pulleys are galvanized anti-skipping flower wheels, which do not require welding to the pulley beam. If welded permanently, it would be extremely inconvenient for future maintenance and adjustment. The pulleys from Yangtze River Film and Television Equipment Factory are all fixed with clamps and bolts. When the boom rises or descends to a certain position, the ABS locking system immediately shuts off the power and locks the motor, ensuring that the boom stops at this position with a low sliding coefficient and high safety.
