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..

chinese vital chain block

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

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.
