VB chain blocks are portable lifting device easily operated by hand chain which are specially advantageous for lifting work in the open air and places where no power supply in available----a kind of manual lifting hoists. VB chain blocks have experienced the forging and heat treatment, and they have surprised capacity they are not easily to break when lifting heavy loads and they have the low failure times/rate. VB chain blocks have high brake safety factor and are not to abrade, which achieve the long life span and the safety of operators.
VB chain blocks equip hit-resistance gear box and the brake cover of the restriction parts of special nuts. In order to protect the bolt, it makes the product’s maintenance achieve the great improvement. Thanks to the bearing structure and unique gear bearing, the top support mechanism mainly utilizes the rounding bearing. Besides, the special double arm ensures the normal working of one spring support when another spring is broken, which greatly improves the durability of products. The gears are small in size but have great function and high intensity. VB chain blocks are equipped with double protection cover which is water-proof and rust-resistant. They require the less hand pulling force and can always move and lift smoothly. And the cover are not to change its shape because they are highly tested and experienced the dealing of many impacts.
