Analysis of Product Characteristics, Application Scenarios, and Operating Standards of Stainless Steel Leverage Gourds

1、 Product Features

Material advantages

Corrosion resistance: Made of 304 or 316 stainless steel material, containing over 18% chromium and over 8% nickel, forming a dense oxide film that effectively resists corrosion in humid, salt spray, and acidic/alkaline environments. For example, 304 stainless steel can remain stable in boiling nitric acid at concentrations below 65%, making it suitable for chemical and food processing applications.

High strength and high temperature resistance: 304 stainless steel has high tensile strength and can withstand huge tensile forces; 316 stainless steel has better high temperature resistance and is suitable for extreme environments such as metallurgy and high-temperature workshops.

Hygiene and Aesthetics: The surface is smooth and easy to clean, in compliance with GMP standards in the food and pharmaceutical industries, and has a silver white metallic luster, enhancing the overall texture of the equipment.

Structural characteristics

Lightweight design: By optimizing the structure (such as high-strength end stop and compact size), the device weight is reduced and portability is improved. For example, some models have a net weight of only 16.5kg, making them convenient for high-altitude operations or mobile use.

Modular components: Key components such as gears and brake systems are designed with modularity for easy maintenance and replacement, reducing downtime.

Humanized operation: The handle can rotate 360 ° to adapt to different operating angles; The load chain or steel wire rope has undergone special treatment to reduce wear and tear.

Safety and functional characteristics

Automatic braking system: equipped with a ratchet and pawl mechanism, the brake is immediately activated when the handle stops operating to prevent the load from falling.

Overload protection: Some models have built-in overload protection devices that automatically cut off power or sound an alarm when the load exceeds the rated value.

Explosion proof design: The explosion-proof stainless steel lever hoist is suitable for flammable and explosive environments such as petroleum and chemical industries through a sealed structure and explosion-proof motor design.

2、 Application scenarios

Chemical and Ocean Engineering

Resistant to the erosion of chemical substances such as acid, alkali, and salt, adaptable to harsh conditions such as salt spray and high humidity, used for equipment maintenance, material handling, and other scenarios.

In offshore platform operations, its rust prevention performance ensures long-term stable operation of the equipment.

Food and pharmaceutical industry

Compliant with GMP standards, the surface is smooth and easy to clean, avoiding contamination, suitable for places with extremely high hygiene requirements such as food processing and pharmaceutical factories.

Used for lifting raw materials, finished products, or equipment to ensure the cleanliness and safety of the production process.

Architecture and Logistics

In construction sites, it is used to lift building materials (such as steel beams and concrete slabs) to improve operational efficiency.

Traction and handling of heavy objects in ports, docks, and warehouses to adapt to humid or salt spray environments.

Mining and Metallurgy

Endure heavy loads and harsh environments to ensure smooth equipment maintenance and material handling.

In high-temperature environments (such as operations in front of metallurgical furnaces), some models can withstand temperatures above 800 ℃.

special environment

Explosion proof places: In industries such as petroleum, petrochemicals, and oil depots, explosion-proof equipment is certified with ATEX, IECEx, and other certifications to prevent spark generation.

Low temperature environment: In cold storage and polar operations, equipment can still work normally at -40 ℃.

3、 Operating standards

Pre operation inspection

Appearance inspection: Confirm that the equipment has no cracks, deformations, or severe wear, and that the load chain, hooks, and other components are intact.

Braking system test: Slowly tighten the hoist and check if the brakes are sensitive and reliable.

Environmental adaptability confirmation: Ensure that the working environment meets equipment requirements (such as temperature, humidity, and concentration of corrosive media).

Load operation

Overloading is strictly prohibited: The load must not exceed the rated load of the equipment (such as 3 tons, 6 tons, etc.) to avoid deviation or lateral tension.

Uniform force: Maintain a steady speed when zipping to avoid impact or braking failure caused by rapid lifting.

Hover handling: If it is necessary to temporarily hover heavy objects, the hoist should be tied to the lifting chain to prevent the self-locking mechanism from malfunctioning.

Multiple collaborative tasks

Unified command: When multiple hoists work together to lift, a dedicated person commands to ensure even distribution of the load.

Synchronous operation: The action rhythm should be consistent to avoid overloading of a single unit.

maintenance

Daily cleaning: Clean the surface of the equipment after each use to remove oil, dust, and corrosive substances.

Regular lubrication: Check and lubricate load chains, gear sets, and other components weekly, using corrosion-resistant lubricants.

Annual maintenance: Disassemble and inspect the lifting mechanism, replace vulnerable parts (such as bearings and seals), and record wear and tear.

Safety taboos

Prohibited behaviors: Overloading, inclined suspension, impact load, continued use in case of brake failure or load chain breakage.

Non professional maintenance: Non professional personnel are prohibited from disassembling or modifying equipment to avoid damaging the original safety design.
