Labor Saving Arm Jack

A labor saving arm jack, often referred to simply as an arm jack or hydraulic lift jack, is a mechanical tool used to lift heavy objects a short distance. It utilizes a series of linked arms and a hydraulic cylinder to multiply force, allowing a single operator to raise substantial weight with relative ease.

Material:

• Steel: The primary construction material is typically high-strength steel for the arms, base, and lifting cylinder. This provides the necessary durability and resistance to bending under load.
• Hydraulic Fluid: The hydraulic system relies on a specialized hydraulic fluid (often oil-based) to transmit force.
• Rubber/Plastic: Components like seals, O-rings, and pump handles may be made from rubber or plastic for fluid retention and grip.
• Welding: Welding is extensively used to join the steel components, creating a robust frame.

Purpose:

The primary purpose of a labor saving arm jack is to lift heavy objects for maintenance, repair, or positioning. Common applications include:

• Automotive Repair: Lifting vehicles for tire changes, brake work, engine removal, or undercarriage access.
• Construction: Lifting structural components, machinery, or materials.
• Industrial Maintenance: Raising equipment for inspection, repair, or replacement.
• Heavy Machinery: Used in conjunction with other lifting tools for larger objects.

Function:

The jack operates on Pascal's principle. A pump handle is used to force hydraulic fluid from a reservoir into a cylinder. This increases the pressure within the cylinder, which pushes a piston upwards. The piston is connected to a series of linked arms that amplify the force, resulting in a substantial lifting capacity. A release valve controls the lowering of the load by allowing the hydraulic fluid to return to the reservoir.

Usage Scenarios:

• Level Surface: Essential for safe operation. Uneven surfaces can cause instability and potential tipping.
• Proper Lifting Point: The jack must be positioned under a designated lifting point on the object being lifted. These points are designed to withstand the concentrated load.
• Safety Stands: Always use safety stands to support the load once it has been raised. Jacks are not intended for long-term support.
• Gradual Lifting: Raise the load slowly and steadily to ensure stability and control.
• Regular Inspection: Check for leaks, damage, and proper operation before each use.

Common Types:

• Floor Jacks: The most common type, designed for automotive use. Typically have a long handle and swivel casters for maneuverability. Capacity ranges vary widely, from 2 tons to 50 tons or more.
• Bottle Jacks: Compact and portable, using a cylindrical shape. Often used in automotive and construction applications where space is limited. Capacity is generally lower than floor jacks.
• Toe Jacks: Designed for lifting objects with a narrow base. Commonly used for lifting machinery and structural components.
• Hydraulic Spreaders: While not a traditional jack, these use hydraulic force to spread or lift objects, often found in rescue and industrial applications.
• Air Hydraulic Jacks: Combine hydraulic and pneumatic systems for faster lifting and increased capacity.

Based on the provided information, a “labor saving arm jack” can be classified under the following HS codes:

• 8425420000: This HS code covers “Pulley tackle and hoists other than skip hoists; winches and capstans; jacks: Jacks”. It specifically includes jacks, suggesting this could be a relevant classification. The total tax rate is 55.0%, comprised of a 0.0% base tariff and a 25.0% additional tariff, increasing to 30.0% after April 2, 2025.
• 8425490000: This HS code also covers “Pulley tackle and hoists other than skip hoists; winches and capstans; jacks: Jacks: Other”. If the “labor saving arm jack” doesn’t fall into a more specific category within 8425420000, this “Other” category applies. The total tax rate is 55.0%, with a 0.0% base tariff and a 25.0% additional tariff, increasing to 30.0% after April 2, 2025.
• 8479899599: This HS code covers “Machines and mechanical appliances having individual functions, not specified or included elsewhere in this chapter; parts thereof: Other machines and mechanical appliances: Other: Other Other”. If the jack is considered a machine with a specific function not otherwise classified, this code might be applicable. The total tax rate is 57.5%, consisting of a 2.5% base tariff, a 0.0% additional tariff, and a 30.0% additional tariff after April 2, 2025, with a 25% additional tariff for steel or aluminum products.

Regarding HS code 8479899599, please note the potential for a 25% additional tariff if the product is made of steel or aluminum.
