Polylifts are a device designed to pull the load on the surface and lift it at different angles. The resulting force for this operation is created through hand force and causes the load to move through the handle installed on the puller to the steel chain through which the tensile force is transferred to the load. Polylifts are available in common tonnages of 0.8 tons - 1.6 tons - 3.2 tons - 6.3 tons.

In polylifts, steel chains with G80 steel grade are used, which have a high percentage of carbon and have high surface hardness and wear. Therefore, the service life of the chain polylift is higher than that of the towed polylifts. In the production of polylift connecting chain, which has a minimum tensile strength of 550 N/mm2, thermal hardening is used to provide high tension and security in the connection.


The lifting industry has witnessed significant advancements over the years, with various tools and equipment being developed to enhance efficiency and safety. Among these innovations, the lever bl

1.6 ton vital lever block

1.6 ton chain lever block can be found in the Iranian market under the VITAL brand of Japan and as a Chinese production plan. There is a significant difference in efficiency, safety and longevity as well as in the price of the original Japanese chain lever block and the Chinese design. The original 1.6 ton Japanese Vital chain lever block has been produced with a safety factor of 5:2, which means that it has been tested as a suspension with 2.5 times its nominal capacity during the tensile test and issuance of the consumer certificate. This means that a 4-ton weight was used to test the original Vital Chain Puller. Regarding the examples of the production plan in China, it is said that the maximum real power in the security mode for these lever block is equal to their nominal power.

1600 kg lever block

The lever block is often used to pull the load or hold the load at an angle, and in rare cases it is used instead of the crane for lifting the load. Of course, the weight capacity of lever block is measured exactly in the hanging state and as a lifting load, and this industrial tool can also function as a crane.
lever block can be found in the market both as a chain with a wider use and as a towing wire with less frequency. lever block connecting steel chains are produced from G80 grade steel, which has a high percentage of carbon and has high surface hardness and abrasion. Therefore, the service life of the chain lever block is higher than that of the towed lever block.

chinese vital 3 ton lever block

3 ton polylift is available in the market with different brands such as VITAL, Japans original Vital, Japans Elephant, and Chinas production plan Vital. Most of the samples of Polylift Vital in the Iranian market are Chinese, which are sold at a much better price than the original Japanese samples.
Vital design polylift with a tonnage of 3 tons is used to maintain telecommunication masts and to place the masts at an angle. The 3-ton chain hoist has a G80 grade steel chain and is 1.5 meters long, and it is considered a manual tool with a lever to hold the load.
