At the time of installation of machinery and equipment, because of human error or inevitable, equipment installation accuracy is always a slight deviation when the device is installed, only the following requirements in line with the requirements of the deviation can be ignored. 1, can compensate for the use of process deviation caused by wear and tear; 2, so that smooth rotation; 3, the relevant parts can be beneficial connections with; 4, can compensate for deviation or after the force caused by temperature changes; 5, without increasing power consumption; 6 so small parts under load force; 7, will help improve the accuracy of the workpiece is often used crane who, in the course of handling equipment, the use of a crane operator, crane shall be conducted stayed oblique hanging, viz. Lifting rope hanging objects through the center of gravity of heavy lifting equipment, and maintain the vertical, oblique hanging stayed that allowed many people do have some questions, why not oblique crane hanging it? 1, it is possible to overload the crane hanging oblique Assuming the weight lifting from the ground for Q objects, vertical lifting, long rope tension S Q equal or slightly greater than Q, the weight can be off the ground. But if stayed, the rope will and at an angle perpendicular to the ground, according to mechanics, rope tension acting on the S, can be decomposed into the vertical upward force P and the horizontal movement of the object the force F, to make the objects hanging from the floor, P at least equal to Q. At the same time with the increase of the angle between F increases. That is a large lifting equipment, the greater the angle oblique hanging when, the greater the force the rope at the same time lifting heavy objects. Therefore, the full load if a vertical lifting weights, then oblique hanging When the inevitable overload, and even pulled off the rope accidents occur. 2, a crane hanging oblique produce inertial force, endangering another person around lifting equipment, generated when the oblique hanging horizontal force F, when leaving the ground in front of the weight but also by influence of friction in a grabbing off the ground, will enable objects to the vertical center of the swing lifting handling equipment, it is possible and hang hanging personnel, operations personnel or other objects around the collisions caused by an accident. In short, if oblique hanging will not only cause overload pull off the rope and swing weights will squeeze hit objects and people, causing physical and handling equipment, lifting equipment accident | Yantai lifting equipment | Lu Lu trusted by Shandong Machinery Installation Co.
