McKissick® 380 Series Hook Blocks

McKissick® 380 Series Hook Blocks are heavy-duty lifting devices used in various industrial applications to lift and move loads safely and efficiently. Manufactured by The Crosby Group, a trusted provider of rigging and lifting equipment, the 380 Series Hook Blocks are designed to withstand high loads and provide reliable performance in demanding lifting operations.
Here are some key features and characteristics of McKissick® 380 Series Hook Blocks:
Design: The 380 Series Hook Blocks have a robust and durable design. They consist of a steel block with one or more sheaves (pulleys) mounted on a central pin. The sheaves have grooves to accommodate wire ropes, providing a secure grip during lifting operations.
Sheave Configuration: The 380 Series Hook Blocks are available in various sheave configurations, including single sheave, double sheave, and multi-sheave designs. The number of sheaves determines the lifting capacity and the number of lines (strands) of wire rope that can be accommodated.
Swivel Hook: The hook block is equipped with a swivel hook that provides flexibility and ease of attachment to lifting devices, such as cranes or hoists. The swivel hook allows the load to rotate freely, minimizing stress on the wire rope and improving lifting efficiency.
Working Load Limit (WLL): Each McKissick® 380 Series Hook Block is rated with a specific working load limit, indicating the maximum load it can safely handle. It is important to select the appropriate hook block based on the intended load requirements and the capacity of the lifting equipment being used.
Safety Features: The 380 Series Hook Blocks often feature safety latches or hooks with safety pins to prevent accidental disengagement of the load during lifting operations. These safety features help ensure secure attachment and enhance overall safety.
Durability: McKissick® 380 Series Hook Blocks are constructed from high-strength steel and undergo rigorous testing to ensure their durability and reliability in challenging working conditions. They are designed to withstand heavy loads, resist wear, and provide long-lasting performance.
Identification and Markings: McKissick® 380 Series Hook Blocks are typically marked with relevant information, including the manufacturer's logo, working load limit (WLL), and other specifications. These markings help users easily identify the hook block and ensure compliance with safety standards.
