Small four-wheel crane small crane Price

Small four-wheel crane small crane prices of agricultural small four-wheel modified small crane. Agricultural small four-wheel modified small crane, Ning Jin Hong Machinery is specialized in the production of small loaders, forklifts, cranes, hydraulic accessories manufacturers, product quality and cheap, durable, after-sale protection, is the first choice for our customers in the small crane the Application of the law of small triangles with a closed triangle crane demand force decomposition. The force is to be broken down as closed side of the triangle, that is, both sides are asking the rest of the force triangle, a known force will be broken down into two component, in addition to the known size of the force is decomposed and direction, but also have the following add one of the conditions. Small crane moment: the role of external forces can rotate objects produce, for example, when the wrench tighten the nut, the nut rotating force. In order to measure the effect of the force for rotating the object, they put forward the concept of "force-to-point moment" (the moment) is. Small crane in the study object is rotated, often called the center of rotation of the object centroid, moments away from the vertical line of action of the heart to force called the arm of the force and the arm of a product called torque. Small crane was represented by the formula:?? M = + P L wherein M torque, in units of N m; P force, the unit is N; L crane arm, in m seen from the above equation, the force on a small crane effects and moments M or rotating object is proportional to the torque the greater the effect will be. Type CKS, minus provisions are as follows; so as to rotate the object clockwise torque is defined as a positive sign, as an object rotates counterclockwise torque is defined as negative. http://jinhongjixie.cn/ Tel: 18753469703 QQ: 3140407523
