DSCK chain blocks are the products of the advanced technology of the world in the form of HS-C hand chain blocks. In addition to the traditional features of the HS-C type chain hoists, DSCK type hand chain blocks have more small hand pull, high safety factor, elegant appearance, more suitable with thicker cover and stronger hooks, which is the best type in triangle type. DSCK chain blocks have  high working efficiency and require low hand pulling force and the safety factor is 4:1.


DSCK chain blocks are most efficient manual chain hoists, which are very ideal for standard industrial duty, standby maintenance or in locations where electrical power is not available. DSCK chain blocks belong to triangular types, and have many names for type here such as HSZ-CK, HSZ-K, HS-V, HSZ-A620, CK all mean the same block. When lifting the weight by hand, pull the chain and sprocket by hand clockwise to rotate, and press the friction ratchet wheel and brake seat into one unit to rotate together. Then, the gear wheel, the short shaft of tooth and the spline hole gear are turned by the long shaft of tooth. In this way, the lifting chain wheel installed on the spline hole gear can drive the lifting chain and lift the weight smoothly. When descending, pull the chain counterclockwise. The brake seat is separated from the brake block, and the ratchet wheel is still under the action of the pawl. The hand pull gourd generally adopts the ratchet friction disc type one-way brake, which can brake by itself under the load, and the pawl meshes with the ratchet wheel under the action of the spring.


Besides the traditional characteristics of HS series chain blocks, it has special advantage below: standard Load limiter automatic overload protection, the cover has been redesigned to protect the gear case and the extended edge of the cover can improve the abrasion resistance of the cover, adopting the deep groove ball bearing of load chain sprocket, pulling is smaller, with rugged steel load bars connected directly to hoist frame. As the fixed pulley of the upgraded version, the hand-pulled block inherits the advantages of the fixed pulley completely. Meanwhile, it adopts the combination of the reducer of reverse brake and chain pulley group to arrange the two-stage positive gear rotating structure symmetrically, which is simple, durable and efficient.


In general, DSCK chain blocks have great quality and high efficiency while operating, and the chain will not easy to break with long life, and can greatly decrease the labor of users. All accessories, such as hooks, connectors etc. are produced by special hot forging. G80 lifting chain is made of high grade alloy  steel that are carefully chosen and sophisticated multi-process heat-treatment techniques have been developed to keep the G80. Compared with other  blocks, their rust-resistant rate has been improved once. They can deal with tough industrial works thanks to their flexibility and great adaptability. What’s more, all of the parameters of DSCK chain blocks have been strictly tested including size, weight, and dimensions in order to ensure the perfect products can be delivered. We promised to provide the best products to our customers. What’s more, the special load test make the load limit is1.5 times more than the original load  limit.


DSCK series manual blocks are easy-handled and easy-operated, portable cranes machines, which are widely used both indoors and outdoors. They are suitable for loading cargoes and installing machines, hoisting and unloading goods in factories, mining mountains, construction sites, agricultural production,  wharfs, shipping, warehouses, especially fit for the outdoor works and areas where there is no power supply. In these areas, they have very important influences and applications. They can hang on the top of the buildings or the beam of cranes, and they can also be used with trolleys to realize the lift of heavy goods both in left and right.

DSCK chain blocks are also called CK chain hoist with load protection, chain block puller, chain block pulley, chain pulley, Hand manual pulley chain block block, chain puller hoist block, HSC chain blocks, HS-C chain blocks, CK type manual chain hoists, CK series chain hoist pulley blocks, CK CPB, CK series chain hoist is based on the HS series.

           ①In order to prevent DSCK chain blocks from the corrosion, operators are supposed to clear them up and paint them with oil, place them on dry areas after using up.

           ②Before starting use the blocks, the friction surface of brake must keep clean and operators have to inspect the brake for ensuring the safety.

           ③No matter the maintenance and test, they require professional workers. Also, the bearing and gears need oil to lubricate.

           ④DSCK chain blocks must experience clearing up and strict inspection to ensure the safe operation and when the brake is stable, we can believe in them.

           ⑤The components of brake require frequent test in order to avoid the failure possibility and the self-falling phenomenon.

           ⑥For the sake of convenience of assembly, one of the hand chains is an open chain (no soldering is allowed)

           ⑦The roller of the left and right bearing of the hoist sprocket can be attached with butter to the inner ring of the bearing which has been pressed on the shaft neck of the hoist sprocket, and then put into the outer ring of the bearing of the wall plate

           ⑧When installing the brake device, the hand  pull gourd should be paid attention to the good meshing between the ratchet gear slot and the pawl's claws. The spring should control the ratchet flexibly and reliably. After installing the hand chain wheel, the hand chain wheel should be rotated clockwise

INSPECTION BEFORE USE
Ensure that the chain block name plate and WLL is clearly visible and legible.
The pre-use inspection for a chain block should include the following:

Load chain
1.Inspect chain for wear.
2.Inspect chain for gouges, nicks, arc burns, twisted & bent links and corrosion.
3.Inspect for correct reeving on multi-reeved units (3 and 5 tonne).
Lift wheels & Sheave wheels
1.Inspect lift wheel for foreign material, wear and corrosion.
2.Inspect dead end pins for wear, tightness and corrosion.

Hooks
1.Inspect hooks for signs of opening, cracking, bending, arc burns and corrosion.
2.Hooks should swivel freely.
3.Inspect safety latches for condition & operation.
4.Measure the hook throats for allowable service openings.

 

Hand chain
1.Inspect chain for wear.
2.Inspect chain for twisted or gouged links and corrosion.
3.Inspect connecting link for signs of opening.
Miscellaneous
1.Inspect frame and covers for distortion, cracks, gouges, corrosion & other damage.
2.Inspect hangers (3 and 5 tonne) for cracks, gouges, corrosion & other damage.
3.Inspect unit for clear WLL identity.
 
CARE IN USE
1.The load chain must always mesh correctly with the load sheave. With multi fall chain blocks twists can arise by turning over the bottom hook through the load chain.
2.Regularly lubricate the whole length of the load chain with machine or gear oil but be careful not to over lubricate as oil or grease on the brake discs can cause the brake to malfunction and slip.
3.Confirm that the brake is functioning properly by hoisting the load 100mm and check the brake when lowering the load.
4.Non-vertical (sideways pulling) of the hand chain is not recommended on our chain blocks.
5.The hand chain is equipped with a safety link. When the safety link opens or deforms, stop at once and inspect for the cause.
6.Confirm that the monorail beam or structure supporting the chain block is of sufficient strength to support the load to be lifted.
7.Never lift loads in excess of the WLL of the chain block.
8.Never walk or work under a hoisted load and never lift, support or transport people.
9.Use chain blocks manually only.
10.Do not permit more than one operator to pull on the hand chain at one time.
11.Lift loads correctly with proper slings and attachments. Never lift with the point of the hook and never use the load chain as a sling by back hooking.
12.Lifting a load with two chain blocks is not recommended. If the operation is unavoidable, hoist the load with utmost care, keeping the load balanced.
13.Never run the load chain out too far. When operated beyond the range of lift, an excessive load that can cause damage will be imposed on the chain block.
14.Chain blocks are designed for lifting loads vertically and should not be used for horizontal or angle hoisting.
15.Extreme temperatures will reduce the durability of the hoist. Loads should be hoisted or lowered very slowly and carefully in extreme temperatures.
16.Never leave a load hanging on the hoist.
17.Never use the chain or hook as a ground for welding.
 
Asbestos free brake, holding load at any desired height. 
- Robust all-steel construction. 
- Top and bottom hooks are fitted with safety latches as standard.
