Wide application and principle analysis of stainless steel lever hoist

1、 The wide application of stainless steel lever hoist

Stainless steel lever hoists play an important role in multiple industries due to their corrosion resistance, high strength, and high temperature resistance. The following are its typical application areas:

1. Chemical and Ocean Engineering

Corrosive environment: In corrosive environments such as acid pickling workshops and chemical plants, stainless steel material can effectively resist the erosion of chemical substances such as acid and alkali, ensuring long-term stable operation of equipment.

Marine platform: In marine engineering, equipment needs to withstand harsh conditions such as salt spray and high humidity. The rust prevention performance of stainless steel lever hoists makes them an ideal choice for offshore operations.

2. Food and pharmaceutical industry

Cleanroom: places with extremely high hygiene requirements such as food processing and pharmaceutical factories. The stainless steel material surface is smooth, easy to clean, and meets GMP (Good Manufacturing Practice) standards.

Aseptic environment: In production lines that require high cleanliness, stainless steel lever hoists can avoid contamination and ensure product quality.

3. Architecture and Logistics

Construction site: used for hoisting building materials and equipment, especially in high-rise building construction, its portability and reliability improve operational efficiency.

Ports and Logistics: Stainless steel lever hoists are used in port terminals and warehouses to tow and transport heavy objects, adapting to humid or salt spray environments.

4. Mining and Metallurgy

Mining operations: In the mining and metallurgical industries, equipment needs to withstand heavy loads and harsh environments. The durability of stainless steel lever hoists ensures smooth equipment maintenance and material handling.

High temperature environment: Some models can withstand high temperatures (such as 304 stainless steel, which can withstand 800 ℃) and are suitable for operation in front of metallurgical furnaces.

5. Special Environment

Explosion proof location: In flammable and explosive environments, explosion-proof stainless steel lever hoists ensure safety through special designs such as sealed structures and explosion-proof motors.

Low temperature environment: Stainless steel material can still maintain good performance under low temperature conditions such as cold storage and polar operations.

2、 Working principle of stainless steel lever hoist

The core principle of stainless steel lever hoist is based on the lever principle and gear transmission, combined with the physical characteristics of stainless steel material, to achieve efficient and safe heavy lifting. The following is a detailed analysis of its working principle:

1. Leverage and gear transmission system

Leverage principle: By operating with a handle, the lever amplifies human power and generates a large output force. The ratio of the handle length to the load arm determines the amplification factor of the force.

Gear set: The power of the handle is transmitted through gear sets (such as worm gears, planetary gears) to further increase torque and drive the load chain or wire rope to lift heavy objects. The design of the gear set ensures transmission efficiency and smoothness.

2. Braking system

Automatic braking device: The stainless steel lever hoist is equipped with an automatic braking system. When the handle stops operating, the braking device immediately starts to prevent the load from falling due to gravity, ensuring operational safety.

Overload protection: Some models are equipped with overload protection devices, which automatically trigger protection mechanisms (such as cutting off power or issuing alarms) when the load exceeds the rated value to avoid equipment damage.

3. Advantages of stainless steel material

Corrosion resistance: Made of 304/316 stainless steel material, it effectively resists oxidation, acid and alkali corrosion, and extends the service life of the equipment.

High strength and high temperature resistance: Stainless steel material has high tensile strength and high temperature resistance (304 stainless steel can withstand 800 ℃), suitable for harsh working conditions.

Hygiene and Aesthetics: The surface is smooth, easy to clean, and meets the hygiene requirements of the food and pharmaceutical industries. At the same time, it has a silver white metallic luster and a beautiful appearance.

4. Structural design

Lightweight design: By optimizing the structure (such as high-strength end stop and compact size), the device weight is reduced and portability is improved.

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

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.
