INTRODUCTIONS

  DS-HSZ-A 619 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. DS-HSZ-A 619 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. DS-HSZ-A 619 chain blocks have high brake safety factor and are not to abrade, which achieve the long life span and the safety of operators.

  DS-HSZ-A 619 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. DS-HSZ-A 619 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.

  The DS-HSZ-A 619 chain blocks adopt the compact structure and light weight but with elegant appearance and unique and creative design. The painting spray is even and the grooves have been calculated reasonably. The hard cover protects the inner parts and components efficiently. Chains are blacken which not only  prevent chains form rusty but also lengthen the lifespan of chains. We also accept the designed products to meet the requirements of customers. What’s more, the plate finish of DS-HSZ-A 619 chain blocks is electrophoretic painting which protects form moisture. Hoist cover painting is done with special technology for long lasting color. They are also equipped with end anchor and each anchor is designed to touch the hoist plate so that it can withstand more force and be stronger. Drop forged steel suspension & load hooks are heat treated and fracture resistant. In case of dangerous overloading or abuse, the hook does not fracture but will slowly yield.

  The blocking chain machine can fit the chain from getting stuck in the hoists when pulling the heavy objects. Confirms to European Standards to prevent it from  being stuck in the middle of wallboard, it has 4.5 times safer than traditional chain blocks in terms of anti-disengagement chain. Besides, the load chain can be pulled freely and easily through the chain blocks in both directions to attach the load or to tension the chain. For safety reason free chains cannot be done when the block is under load. All of our DS-HSZ-A 619 chain blocks are meet the 1005 EN standard with  anti-corrosion coating, they can work in tough environments. And they are all  check in the whole manufacturing process and 100% inspection before shipment ensuring the quality.

  TOP quality DS-HSZ-A 619 chain blocks are widely applied in factories, mines, farms, construction sites, wharves, docks and warehouses for installation of equipment, as well as for loading and unloading goods. DS-HSZ-A 619 chain hoists can be attached to a trolley of any type as a  traveling chain hoists are suitable to monorail overhead conveying system, and travelling crane and jib crane. They can also used in double beam cranes, gantry cranes, bridge cranes, tower cranes, single grinder cranes, lifting platforms, small cranes.

  DS-HSZ-A 619 chain blocks are also called Hand chain hoists, Hand operated hoists, Mechanical hoists, Manual hoists, mini manual chain hoists, manual pulley hand chain hoists, chain hoists, chain blocks, manual operated chain fall engine hoist blocks. Its type also called VB, VC-B, VCB, VS, HSZ-T, TD, 619, HSZ-A619, all mean the same thing.


DETAILED DESCRIPTION

1. Bolts

         The parts of DS-HSZ-A 619 chain blocks are fixed by different sizes of bolts which have high intensity. In order to ensure the quality, we adopt the advanced and great bolts to make fix safer.

2. Hook

         The hooks adopt high quality alloy steel. We widen the space of  hooks and both the hooks utilize the high quality alloy steel material, experienced with heat treatment and the strict test, they meet high standard of the international. What’s more, they can bear the load when they are over 4 times which greatly improve the overload situation. It has big capacity and they make light a reality and more reliable and safer than others.
