Tie a rope and pulley and accord with the ball on the pulley ลูกล่า.The weight was hanging with a rope, two lines. Tension rope each line is equal to half the weight lifting and equal strength using traction lift. So if the pulley on the tense and is moving into liver liver is two.Pulley series liver can labor operations. The rate of liver to relax the tension pulley that depends on the number of wire rope. - come between the pulley both liver, such as a rope four line will labor has four times.Crane used along the harbour or the construction site is a simple machine, which uses a mechanical labor-saving pulley.
