-- Used for grab bucket/crane/container lifting spreader
The pulley is an indispensable and crucial component in lifting equipment and handling equipment. It is usually a grooved wheel that can rotate around a central axis.
The edge of the wheel has a groove, which is used to accommodate flexible components such as ropes, chains, or belts. It generally consists of a hub, spokes, and a rim.
The hub is used to be installed on the shaft, the spokes connect the hub and the rim, and the groove on the rim ensures the stable operation of the ropes and other components.
Types
1. Fixed Pulley: The shaft of the fixed pulley is fixed and does not move.It is mainly used to change the direction of the force, neither saving nor requiring more force.
In lifting and handling operations, it is often used to convert the vertical pulling force into a more conveniently operable horizontal pulling force, or to guide the force to an appropriate position, so that the operator can better control the movement of the heavy object.
2. Movable Pulley: The shaft of the movable pulley moves together with the lifted heavy object.It can save force but cannot change the direction of the force.
At the loading and unloading dock, using a movable pulley allows workers to lift heavier goods with less force, reducing labor intensity and improving the loading and unloading efficiency.
3. Pulley Block: The pulley block is composed of a combination of fixed pulleys and movable pulleys. It can both save force and change the direction of the force.
By reasonably combining the number of fixed pulleys and movable pulleys, different force-saving multiples can be obtained according to actual needs.
In large lifting equipment such as cranes, pulley blocks are widely used and can easily lift heavy objects weighing several tons or even dozens of tons, meeting the needs of various lifting and handling operations.
Application
Functions and Advantages
1. Force-saving and Efficient
2. Precise Control
3. Multifunctionality
In lifting equipment and handling equipment, the pulley, with its unique structure and working principle, plays an irreplaceable role and is one of the key components for achieving efficient and safe lifting and handling operations.
Working Principle
The pulley mainly operates based on the principles of the lever and friction.
When a rope or chain passes around the pulley, the axis of the pulley is equivalent to the fulcrum of the lever, the pulling force of the rope serves as the driving force, and the gravity of the lifted or moved heavy object acts as the resistance.
By changing the direction of the force and the length of the force arm, the pulley can achieve the effects of saving force or changing the direction of the force.
At the same time, the frictional force between the pulley and the rope ensures the effective transmission of the force, enabling the heavy object to move in the expected direction and manner.
