Overview

A 50-ton crane hook is a heavy-duty lifting accessory designed to support and move loads up to 50 tons. Made of high-strength forged steel or carbon steel, it's durable and safe for use in heavy industry, mining, and logistics. Key features typically include a safety catch for securing the load, 360-degree rotation for maneuverability, and a compact, stable design. These hooks are essential for overhead, gantry, and mobile crane applications, ensuring the efficient and safe handling of heavy loads.

Single Hook for Cranes
Description: The single hook is the most common type for 50-ton cranes, simplifying manufacture and use.
Application: Suitable for lifting capacities of 50 tons and below, and is a standard feature of Weihua's 50-ton cranes.

Double Hook for Cranes
Description: The 50-ton crane double hooks provide more symmetrical load distribution and more even weight distribution.
Application: Often used in heavier workloads and demanding applications. Double hooks are also a common configuration for the 50-ton class, providing better load distribution.

Features

The Weihua 50-ton crane hook is forged from premium alloy steel, featuring a safety latch and optimized pulley design. It ensures reliable, high-performance lifting for industrial applications like manufacturing, logistics, and heavy equipment handling.

High-Quality Alloy Steel

The Weihua 50t hook is forged from high-grade alloy steel (such as DG20Mn and DG34CrMo). This material possesses exceptionally high tensile strength and toughness, capable of withstanding 50-ton loads and inevitable impact loads, effectively preventing sudden breakage.

Advanced Heat Treatment

Through precise quenching and tempering, the crane hook achieves exceptional surface hardness and wear resistance while maintaining core toughness, achieving the ideal "hard exterior, tough interior" performance and significantly extending its service life.

Precision Forging

The forging process ensures continuous and complete metal fiber flow, eliminating internal defects and resulting in a load-bearing capacity far superior to that of ordinary cast hooks.

Standard Anti-Hook Device

A high-strength safety tongue (lock) is installed at the 50 tons crane hook opening as a mandatory safety feature. It effectively prevents the wire rope, sling, or chain from slipping out of the hook due to sway or slack during operation, significantly enhancing operational safety.

Low-Fatigue Design

The curved portion of the crane hook body features a smooth curve that conforms to ergonomics and mechanical principles. This effectively distributes stress and reduces stress concentration, thereby minimizing the risk of fatigue cracking caused by long-term cyclic loading.

Strict Quality Inspection

Every Weihua crane hook leaving the factory undergoes rigorous non-destructive testing (such as magnetic particle testing or ultrasonic testing) to ensure it is free of internal defects such as cracks and slag inclusions.

Note:
Non-fixed values: The above dimensions and weights are estimates. The most accurate data plate is usually mounted directly on the crossbeam or pull plate of the hook assembly. Please refer to the actual nameplate for accuracy.
Compatibility: The hook assembly is the core component of the crane and must be strictly compatible with the hoisting mechanism (wire rope, drum, motor power). Replacing the hook with a non-original or incompatible model is strictly prohibited.

If you need exact crane hook drawings or specifications for a specific crane model, the most reliable methods are:
1. Consult the crane's Operation and Maintenance Manual.
2. Contact Weihua Group's official customer service or after-sales service and provide the specific crane model and manufacturer's serial number to obtain accurate technical data for genuine accessories.

Application

Weihua's 50-ton crane hook, as a core load-bearing component, is primarily used in industrial sectors requiring large-scale and high-weight lifting of heavy objects. 50-ton crane hook is a key lifting tool in heavy industrial manufacturing, large-scale logistics, infrastructure projects, and energy project construction. Its strong load-bearing capacity and high reliability make it commonly used in large-scale component assembly in heavy machinery plants, turbine and transformer lifting in power generation equipment manufacturing, engine and hull segment handling in shipbuilding, and loading and unloading of heavy containers and large equipment in large logistics centers, port terminals, and railway yards. 50-ton crane hook also plays an indispensable role in infrastructure and energy scenarios such as the installation of prefabricated bridge components and the construction and maintenance of power plants.
