Product Characteristic： The hand chain block tends to be more favoured for applications where there are either long intervals between use or frequent changes of use, which calls for particular attention to be paid during the in-service inspections procedures to ensure that no significant damage or deterioration has occurred since last used. It’s important to note that Manual Chain Hoists are only designed for hoisting and lowering loads, and not for pulling applications. For pulling a lever operated machine is more suitable. Where a chain block is suspended from a hook, the suspension level is the level of the suspending hook saddle. In the case of a block combined with a trolley, it is the level of the surface upon which the trolley runs. In other cases, it is similar appropriate levels. Product Specification：
