BZD slewing jib crane, upper slewing using two tapered roller bearings Alar lifting equipment, the boom is running more smoothly Alar lifting equipment, rotary devices using cycloid reducer, small input power, output torque, the feeding device is mounted on the top of the column, easy installation and maintenance, from the weight 0.25T-8T, boom up to 12 m. From elevated section up to 12 Lal Mia lifting equipment, optional remote control. When 0.5t-2t jib crane beam installation, rotary spindle aligning bearing hole at the top of the column; roller against the upright circular orbit slow down. Force through a side door pillar holes retaining washer and a round nut. Installation slip ring contacts mounting method has been talked about the last article, I am not doing explained. Slewing jib cranes crane jib cranes Cranes intensity of light, the crane from the column, the pivot arm and hoist rotary drive unit composed of the lower end of the column is anchored by a concrete foundation, the cycloid means driving the boom rotary, electric hoist cantilever beam in a straight line for about running and lifting heavy objects. Crane jib hollow steel structure, light weight, span, lifting capacity, economical and durable. Built-in running gear, made of special plastic with rolling bearings go round Alar lifting equipment, friction is small, brisk walking; small structure size, especially help to improve the hook travel.
