7/8" x 1-3/4" Category 1 Forged Lift Arm Pins Yellow Zinc Plated

what is 7/8" x 1-3/4" Category 1 Forged Lift Arm Pins?

The 7/8" x 1-3/4" Category 1 Forged Lift Arm Pins is typically designed for agricultural or industrial machinery, particularly for tractors and other heavy equipment that utilize a three-point hitch system.

1. Material and Manufacturing

Forging process: Being forged gives the pin high strength and durability. The forging process allows the metal grains to align in a way that enhances the overall structural integrity. This is crucial for withstanding the significant forces exerted on lift arm pins during operation.
Material quality: Typically made from high - quality steel alloys. These alloys are selected for their ability to resist wear, corrosion, and fatigue. For example, some may contain elements like chromium or nickel which improve corrosion resistance.

2. Dimensions

The specific dimensions of 7/8" in diameter and 1 - 3/4" in length are designed to fit precisely within the lift arm assembly. This accurate fit ensures proper alignment and smooth movement of the lift arms, which is essential for the efficient operation of equipment such as excavators or backhoes.

3. Load - Bearing Capacity

Designed to handle substantial loads. Category 1 classification indicates that it can bear a certain level of weight and stress. This is important as lift arms are often subjected to heavy payloads during lifting operations.

4. Surface Finish and Coatings

May have a good surface finish to reduce friction. Some may also be coated with materials like zinc plating for additional corrosion protection. A smooth surface finish helps in minimizing wear between the pin and the mating components.

5. Compatibility

Specifically engineered to be compatible with Category 1 lift arm components. This means it will work seamlessly with other parts of the lift arm system in terms of dimensions, load requirements, and movement patterns.

The Cat.1 Lift Arm Pin is primarily used in the three-point hitch system of tractors, specifically designed for tractors with Category 1 (Cat.1) hitches. This hitch system is commonly found on compact and smaller tractors, and the lift arm pin plays a critical role in the connection between the tractor's lift arms and various implements.

Here are the key applications of the Cat.1 Lift Arm Pin:

1. Construction Machinery

In excavators, the lift arm pin is crucial for connecting the lift arm to the boom or the main body of the machine. It enables the smooth movement and lifting of heavy loads such as soil, rocks, and construction debris.
on a lift arm - to the machine. This connection is essential for the bulldozer to push large amounts of material like sand or earth effectively.

2. Agricultural Equipment

Tractors use lift arm pins for implements like front - end loaders or hay balers. When a front - end loader is attached to a tractor, the lift arm pin secures the loader so that it can lift and move heavy bales of hay or other agricultural products.
In combine harvesters, it may be involved in the attachment of components such as the grain header, which needs to be raised and lowered during harvesting operations.

3. Industrial Lifting Devices

Forklifts may use similar pins in their lifting mechanisms. These pins ensure that the forks, which are used to lift pallets of goods, are securely attached to the lifting arm. This is vital for safe and efficient handling of materials in warehouses and factories.

4. Maritime and Offshore

On some small - scale cranes used on ships or offshore platforms, the Cat.1 lift arm pin can play a role in connecting the crane's boom segments or attaching the hook block to the boom. This helps in loading and unloading cargo from ships or handling equipment on offshore installations.
The Cat.1 lift arm pin is designed to meet specific strength and durability requirements to handle the high - stress conditions in these various applications.
