Bottom Hook Assembly Components（Single Chain）

The image shows the disassembled components of a bottom hook assembly for a chain hoist. Each part is labeled for identification:

Bottom Hook with Latch: The main hook component, painted in orange, with an integrated safety latch to secure the load.

Shackle: A structural component designed to connect the hook to the other parts.

Shackle Sleeve: A circular sleeve used to enhance the connection between the shackle and other parts, providing stability and reducing wear.

Bearing: A cylindrical bearing for smooth rotational movement of the hook.

Bottom Hook Guard: Two identical protective covers designed to shield the hook assembly and bearing from external impacts or wear.

These parts together form the bottom hook assembly, a critical element in crane lifting operations for securing and rotating heavy loads.
