舞台吊杆是各类剧场吊幕、吊灯和吊景不可缺少的机械装置。目前剧场大都采用手拉式、卷筒式、平衡锤单式及平衡锤复式吊杆装置。由于吊杆的升降采用手动方式,对有些剧情要求吊幕、吊景升降较频繁的场面及要求吊幕、吊景位置精确的场合,操作人员往往手忙脚乱难以将位置定准。为此,我们与有关科研单位配合,在国内有关厂家生
The stage boom is an indispensable mechanical device for all kinds of theater hanging curtains, chandeliers and hanging scenes. At present, most of the theaters use hand-held, reel-type, counterweight single hammer and counterweight double boom devices. Since the boom is lifted and lowered manually, for some scenes requiring hanging curtains, climbing scenes that are frequently raised and lowered, and locations where hanging curtains and hanging scenes are required to be located accurately, the operators are often in a hurry to make it difficult to position them. To this end, we cooperate with the relevant scientific research units and are involved with relevant manufacturers in the country.
