china vital 1 ton chain block

The 1-ton manual chain hoist, VITAL design, is a reliable mechanical lifting device for handling loads in industrial, workshop, and construction environments, operating with a simple mechanism without the need for electricity or hydraulics. This hoist features a durable steel body with anti-rust and wear-resistant coating, ensuring consistent performance against impact and harsh weather conditions. Its internal system consists of heat-treated steel gears with high surface hardness typically in the 50–60 HRC range and a safety factor of 4:1, allowing it to safely handle a rated load of 1000 kg. The automatic brake mechanism, equipped with wear-resistant friction plates, ensures secure load holding at any height and prevents sudden load release. Due to its compact design and lighter weight compared to similar models, this hoist is easy to transport and install in various worksite locations.

The load chain of the 1-ton manual chain hoist, VITAL design, is typically made from alloy manganese steel with a **G80** grade, compliant with **EN 818-7** standards for lifting applications. The chain size is generally **6 mm**, with a nominal tensile strength of approximately **800 MPa**, capable of withstanding both shock loads and long-term use. The chain surface is protected with a bl

**Paragraph 1 Technical Specifications of 5-ton Vital Chain Hoist – Chinese Model:**
The 5-ton Vital VITAL manual chain hoist from China is designed for heavy-duty industrial applications with a precise load capacity of 5,000 kg. It features a high-carbon steel chain with 800 MPa tensile strength and hardened-tooth gear mechanisms. The standard chain length is 3 meters, extendable up to 6 meters. The body is constructed from impact-resistant steel with an anti-corrosion epoxy coating. A dual-action centrifugal brake system ensures operational safety. The unit weighs 28 kg and operates within a temperature range of -25°C to +60°C. This model complies with ISO 9001, CE, and GS standards.

**Paragraph 2 Comparison with Japanese Original Product:**
Japanese hoists like KITO’s 5-ton models use alloy steel with 1,000 MPa strength and chrome-molybdenum chains for enhanced durability. Manufacturing precision in Japanese units reaches ±1%, compared to ±2% in the Chinese Vital model. The braking system in Japanese hoists carries TUV certification, while the Chinese version meets only CE standards. Japanese hoists weigh around 25 kg and operate from -30°C to +70°C. Pricing for Japanese hoists is 40% higher than the Chinese Vital model, but they come with a 5-year warrant

chinese 3 ton chain block

The 3-ton manual chain hoist, Chinese VITAL design, is engineered for the safe handling of heavy loads in industrial sites, workshops, and construction projects. The unit features an alloy steel body with an anti-rust and wear-resistant coating, ensuring long service life. Its power transmission system includes heat-treated steel gears with a surface hardness of approximately 55–60 HRC and lubricated bearings to reduce friction. The hoist has a rated capacity of 3000 kg and a standard lifting height of 3 meters, making it suitable for various applications. The net weight is approximately 28–32 kg, which, despite the high capacity, allows for relatively easy transport and installation.

The load chain of this hoist is made from manganese alloy steel, grade G80, and meets EN 818-7 standards for heavy lifting applications. The chain size is typically 10 mm, with a tensile strength of around 800 MPa, capable of handling both dynamic and static loads. The chain surface is treated with black phosphate or galvanized coating for enhanced corrosion resistance. The hoist usually has a safety factor of 4:1, which in static tests means withstanding at least 12,000 kg before failure. These features make this model a reliable choice for industrial and heavy-duty operations.

Due to the fact that hand chain cranes do not require electricity, this industrial product is widely used in workshops. Hand chain crane is a tool in the form of a block with simple and limited components, which provides users with the ability to carry loads of up to 25 tons without the need for special electrical equipment. The only requirement for using the manual chain crane that can be found in the market in its original form and design is to have ceiling weight capabilities, i.e. a hook with stable weight conditions or a ceiling rail that is installed by using iron sharps.
The manual chain crane uses a chain to connect the load to the crane and also as a connection to transfer the power of the hand and move the load.

Chain block G80 chain

Two different grades of chains are used on chain blocks that are used for lifting purposes. the hand chain that is pulled by hand is used with lower grades and usually as galvanized with zinc coated surface. this grade of chain has lower levels of carbon and under goes very mild load. on the other hand there is one more chain that is usually used as surface phosphate and in dull black color which is attached at the bottom to a hook and is used for connecting and lifting the load. G80 chain is the most common industrial grade of chain and is produced by hot forging and under goes a heating process in order to increase the tensile strength and surface hardness..

The manual chain overhead crane is used both as 2-way and 4-way. The 2-way chain hand crane uses a hook to connect to the ceiling hook and does not have the ability to move the load horizontally after lifting. Vial 2-way chain hand crane can be supplied in the original form of Japanese production in Dena Bexal trading, and also in the Chinese design, which are often used in the tonnage of 1 to 10 tons. The main examples of Vital chain hand cranes are manufactured according to AS1418.2 standard and have extra load safety protection and are marketed along with JIS and ISO standards.

25 ton chain block

Chain block is used in most industrial applications as a chain. In fact, unlike electric hoist that use electric power, lifting with a manual crane is done manually by rotating a chain, and therefore it is a very suitable choice for lifting in areas where there is no access to electricity. A manual crane consists of a block, inside which a central shaft, bushing and bearing and several gears and sprockets work together to move the manual chain in a long length with low energy to move on the load steel chain. They transmit in a small amount but with high elasticity.

VITAL 5 ton manual crane can be supplied both in the original production of the prestigious Vital brand of Japan and in the Chinese production plan in Top Wire Trading. The 5-ton manual crane is supplied as a 2-function, that is, with a hook for ceiling connection and only with the ability of vertical lifting, and with the ability to be converted into a 4-function. The 5-ton 4-function manual crane is supplied with a carriage that can be simple manual or chain type, which provides the conditions for horizontal transfer of the load after lifting.

VITAL Manual chain block

VITAL chain block is in fact made in Japan , however most of the chain blocks available in the market right now are knock off and made in china. chain blocks are very useful mechanical tools for lifting purposes, specially where there is no electricity. VITAL chain blocks are usually available as two dimensional instruments and for hanging anf lifting items. being very durable and practical chain blocks have two chains one to be handled by hand which is galvanized and the other to be attached to the weight which is usually G80 grade.

Harrington 2 ton chain block

Harrington hand crane is actually a product of the United States, while the examples available in the Iranian market are made in China and are designed and sampled from the original product. Harringtons 2 ton manual crane uses a 6 mm hand chain, which is produced in the low grade of G43, and its movement is done manually by the operator. At the point of connection to the load, the Harrington 2 ton chain hoist uses a dry steel chain in G80 grade and 10 mm in size, which is matte black in color and has a very high tensile capacity.
