Description and characteristics of the crane boom crane jib cranes thing is the intensity of light, the crane is driven by a rotary column, the pivot arm and plans to manufacture electric hoist consisting of a solid concrete column below the fundamental, use cycloid device driving the boom back hanging, electric hoist for the cantilever beam to be sad in straight line running, and lifting the weight of items. Crane jib hollow steel layout, light weight, span, lifting capacity, economical and durable. Special engineering plastics go round with rolling bearings, friction is small, brisk walking; the layout a little, especially help to improve the hook travel. Cantilever crane crane is practical contemporary production and the production of a new generation of lightweight lifting configuration, wall jib crane, together with high reliability electric chain hoist is especially useful for short distances, Fujin jib crane, the use of frequent, intensive of lifting operations, the wall line jib cranes, with high efficiency, energy saving, save time, simple, small footprint, easy operation and maintenance. More motorized mobile cantilever crane maneuver, wide compliance category, is a highly efficient automatic production line necessary for the lifting of emergency alone configuration, with the production line to ensure the unimpeded flow of it. (7) prohibits the crane can not guarantee the park and were on the tip of lifting and Turnout on a stable or bad line. (8) on the curve crane lifting operations, lifting equipment should be reduced by 20% in cargo hanging curve when walking, from the weight should be reduced by 40%. (9) prohibits the use of cranes over the goods specified in the instructions ramp hanged traveled. (10) on the same line when several cranes working together, each crane hook spacing of not less than 5m, crane travel time rows close to each other, should send warning signals to each other. (11) work in the derailment or the occurrence of mechanical damage, the driver should quickly put down heavy lifting. Such as when the weight is not down, the place to deal with heavy objects may fall to be protective.
