Heavy-Duty Crane Hook Block Assembly (3-Sheave Type) With Safety Latch
High-performance crane bottom block assembly featuring a forged alloy steel hook and three wear-resistant sheaves. Engineered for stability, safety, and heavy-load lifting operations for overhead and gantry cranes.
- Product Introduction
Key Features:
Heavy-Duty Construction: The hook is forged from high-grade alloy steel (e.g., 35CrMo or DG20Mn), strictly tested for impact resistance and load capacity.
3-Sheave Configuration: Equipped with three precision-machined red sheaves (pulleys) to increase mechanical advantage and reduce wire rope tension.
Safety First: Includes a heavy-duty safety latch to prevent accidental unhooking and protective yellow cheek plates with high-visibility safety markings.
Smooth Operation: The sheave bearings are sealed and lubricated to ensure low friction and smooth rotation under load.
Rotation: The hook is capable of 360-degree rotation, allowing for easy positioning of the load.
