INTRODUCTIONS

  DS-HBSQ Chain Blocks are the kind of simple to use and easy to carry manual lifting machinery, which controlled only by pulling handlebar chain. They are explosion proof chain blocks, As the small material handling equipment, spark proof DS-HSBQ chain blocks are used to lift something in industries, and also can avoid the flammability explosion which happens when there are some frictions and crash between the hoist and the goods. Due to the special material adopted, They can be widely used in the hazardous environment such as petroleum, chemical industry and gas extraction. 

  The working principle of our explosion proof chain blocks is very easy to understand. It starts to turn through tracer chain and sprocket; the friction disc ratchet wheel and brake seat (pressed into a whole) rotate together; the five-tooth long shaft  turns the piece gear, four-tooth short shaft and spline-hole gear. As a result, the sprocket installed on the spline gear drives the chain and lifts the weight stably.

  Our explosion proof chain blocks have the characteristics of small tension, light pulling, small weight, bright appearance and long service life. The calabash is made of special material, which can avoid the friction and impact of mechanical sparks when working in the dangerous environment of potential fire and explosion. And the special materials are aluminum bronze and beryllium bronze, which are relatively expensive production  materials. All main components of DS-HBSQ explosion proof chain blocks like gears, sprockets and hand wheel covers are made of the advanced-technology material of copper alloy through die forging of large friction press machine. The shell of the hand-pulled calabash is made of H62 copper alloy. The rotating gears of the explosion proof chain blocks are subjected to high temperature heat treatment so that the gears have high wear resistance. Stainless steel hand chains adopt 800MPa high-strength lifting chain, which make our chain blocks more durable. What's more, those accessories in casting is installed, debugged and tested in according with the general hoisting equipment national standards strictly, and its performance of explosion-proof is in line with GB/10686-1989 standards completely, and also each data coincides with Q/QJY01-2008 stands totally. 

  Due to the high-technology, all our DS-HBSQ explosion proof chain blocks have the good meshing between the tooth groove of the ratchet wheel and the pawl of the ratchet wheel. However, when installing the brake device, please check again just in case. And the spring should be flexible and reliable in controlling the ratchet claw. Therefore, after installing the sprocket wheel, please rotate the sprocket wheel clockwise to press the ratchet wheel and friction plate on the  brake seat. What’s more, the operator should stand in the same plane with the hand sprocket when pulling the hand chain, so that the hand  sprocket rotation along the clockwise direction, which can highly make the process of lifting loads become more easy and convenient. And if the operators want to put the loads down slowly, just pull back on the chain is OK.

  DS-HSBQ explosion proof chain blocks can be widely used in petroleum, petrochemical, gas station, oil depot and gas extraction, chemical industry, military industry, electric power, mining, electronics, railways, and other potential and explosion dangerous environment. What's more, product friction in operation will not produce mechanical spark, which effectively prevents the fire accident and ensures that factory's property  and personal safety, the explosion proof chain blocks are also the special tool, which are essential for machinery manufacturing and maintenance. And in the places without power and outdoors, it is more advantaged and favorable.

  Besides, our DS-HBSQ explosion proof chain blocks also can be used alone with electric hoist, chain or electric car together. Except hanging on the roof of the building or using on the crane beam, it also can cooperate with monorail car and walk around ascension weight functions as well as help to install electric hoist. 

  DS-HBSQ explosion proof chain blocks are also called Explosion-proof chain blocks, Non spark chain blocks, Explosion-proof chain hoists, Non spark chain hoists, Non sparking chain hoists, Non sparking manual chain hoists, spark proof chain pulley blocks, spark proof chain hoists, spark resistant chain hoists, spark resistant chain blocks, spark resistant hand chain hoists, Anti-explosion chain blocks, Anti-explosion chain hoists, Copper chain blocks, Copper alloy safety chain blocks and Explosion proof copper anti sparking chain blocks.


DETAILED DESCRIPTION

1.Shell

All copper shell is thickened and strengthened, which can completely protect the internal parts and provide safer explosion protection for the operators. And the outer shell adopts H62 copper alloy material to be applicable in flammable and explosive occasions, such as chemical industry, sea and other operations.

Others

①Cautions

.Overload and power operation other than manpower, as well as improper operation such as heavy object hanging on the tip are all strictly prohibited.

.Please make sure the parts are in good condition before use. The transmission part and lifting chain are well lubricated and idling is normal. Please check whether the upper and lower hooks are fastened before lifting.

.The hoisting chain of DS-HBSQ explosion proof chain blocks should be hung vertically. And there should be no wrong twisted chain link.

.When lifting heavy objects, it is strictly forbidden to do any work or walk under the heavy objects to avoid personal accidents.

.The gourd should be cleaned and coated with anti-rust grease after using, and stored in a dry place. Maintenance and overhaul should be carried out by those who are familiar with the gourd mechanism, to prevent those who do not understand the performance principle of the machine from disassembling and assembling at will.

.The friction surface of the brake must be kept clean. The brake part should be checked frequently to prevent the brake failure and the phenomenon of falling of the intermediate object.
