Heavy Duty Crane Pulley Block

Description

The crane pulley block is a crucial component in overhead crane equipment. It consists of pulley, shaft, bearing, housing or frame and hook. The pulley is usually made of high-strength cast iron or cast steel with carefully-design rope grooves. The shaft and bearing ensure smooth rotation, while the housing provides stable support. And the hook guarantees the safe hanging of heavy objects. It has many advantages such as saving effort and increasing efficiency, flexibly changing the direction of force, and ensuring the safety of lifting operations. According to functions, there are force-saving pulley block and speed-increasing pulley block. Defined by the structure, there are single-link and double-link pulley blocks. It is mainly using in many fields such as ports, construction sites, and factories. Users should do daily inspections, regular maintenance, and operation in accordance with regulations to ensure its good operating condition.

Dafang designs the pulley with high-strength metal materials to ensure sufficient strength and wear resistance. The pulley shafts are key parts that support and drive the pulleys to rotate, bearing the corresponding forces. The bearings ensure that the pulleys can rotate smoothly and reduce friction. The clamping plates play a role in stabilizing components such as pulleys.

The crane pulley block plays the role of connecting the hook and the drum. Through the ingenious combination of pulleys, it achieves a labor-saving effect. This enables the overhead crane or gantry crane to lift heavy objects with a relatively small pulling force. On the other hand, it can also adjust the speed of the hoisting mechanism and optimize the overall performance of the crane equipment. In port loading and unloading, construction site lifting and factory material handling, it helps the bridge crane to complete the lifting of various heavy objects safely and efficiently.

Features

• Energy-saving and high efficiency
  • Through the combination of pulleys, it can lift heavier objects with less pulling force, saving labor and energy, and improving lifting efficiency.
• Flexible direction
  • The direction of force can change flexibly, so that the heavy objects can be moved and positioned in multiple directions with precise control, making the operation more flexible and accurate.
• Safe and Reliable
  • With high quality materials, the structure is stable, and there are devices such as anti-decoupling and overload protection to ensure the safety of lifting.
• Various adaptations
  • There are various classifications in function and structure, which can be applicable to different cranes and lifting conditions.
• Widely used
  • It plays a key role in the lifting work in many industries such as harbor, construction site, factory and so on.
• Durable
  • The parts work well together to reduce wear and tear, and can be used for a long time with reasonable maintenance.
