The 508mm large diameter tandem block is equipped with the most suitable conductor LGJ400. In other words, our products are suitable for wires with a nominal cross-section of aluminum up to 400 square millimeters. Block size (outer diameter * root diameter * pulley width) is Φ508×Φ408×75 (mm).

The Diameter 508 series pay-off block is a type of equipment used in the construction and engineering fields, usually used to lift, move and position heavy objects. The following is a basic introduction to the diameter 508 series pay-off block:

1. Functions and uses: Diameter 508 series pay-off block is mainly used for lifting and moving heavy objects, such as steel beams, concrete components and so on. They provide an efficient way to manipulate large components on construction sites or in factories.

2. Construction and design: These blocks usually consist of a wheel with a diameter of 508 mm (about 20 inches), a size that allows them to withstand large weights and provide stable support. They are usually made of high-strength steel to ensure their durability and reliability.

3. Operation mode: The operator usually uses a sling or rope to lift the heavy object to the pay-off block, and then controls the movement of the pay-off block manually or mechanically. Some models may be equipped with manual or electric winches for easy control of lifting and moving heavy objects.

4. Safety considerations: When using diameter 508 series pay-off block, safety operation procedures must be strictly followed. This may include regularly checking the condition of the equipment, ensuring that appropriate slings and ropes are used, and ensuring that operators are trained to operate the equipment properly.

5. Field of application: These blocks are usually used in construction sites, bridge construction, port loading and unloading, and other occasions where heavy objects need to be moved and lifted.
