Electric wire rope hoist choose how to enhance the size of the weight and material
In industrial production which is very broad, the use of wire rope electric hoist wire rope electric hoist model range, size and material according to the weight that you upgrade to select the appropriate wire rope electric hoist to be able to meet the demand of the customers, and then how to analyze the forcesize?
We believe that, by both external and internal forces to master:
1, the external force: the steering pulley discussed in the balance of forces in, drag external force rope P1, P2, and the pulley and the shaft friction in the lifting former Cooling arm, the calculation, the external force acting on the top of it a P1, P2, P3 Q and the weight of the water-cooled arm and reinforced frame composed of four parts.
2, the internal forces: crane by extremely heavy rope hanging heavy objects off the ground, and stop in the air, in addition to extremely heavy rope in equilibrium under the action of external forces (crane hooks and weights). Extravasation phenomenon also found oil in extremely heavy rope hemp core objects (components or materials) is calculated, not only to know the external forces, and the interior of the object you want to know this force to resist deformation.
The master external and internal forces, are better able to choose the applicable wire rope electric hoist heavy lifting.
