The magnitude and span of low headroom electric wire rope hoist
The amplitude of the low headroom electric wire rope hoist is jib crane with luffing mechanism horizontal distance between the center of rotation perpendicular extract device perpendicular m, this distance with the angle of inclination of the crane boomis changed, the most significant R refers to the center of rotation of the crane to reach the maximum horizontal distance perpendicular and extract means between perpendiculars. This parameter directly determines the hoisting cranes can reach the position and lifting equipment (components) geometry and lifting height.
Span for the trays and cable cranes, bridge cranes, refers to the horizontal distance between the centerline of the track of the tray amount. For cable crane, the parameter is fixed, it directly determines the scope of work of the crane. Therefore, in the design of materials, equipment stacked assembly venues, to determine such cranes parameters according to process requirements.
