INTRODUCTIONS

DSVC-A Chain Blocks are a portable lifting device easily operated by hand, which can be attached to a trolley of any type as a traveling chain blocks and one kind of using simply and carrying easily manual hoisting machinery. After absorbing the advanced technology in the world, DSVC-A Chain Blocks are improved on the basis of HSZ series. Except for the traditional characteristics of HSZ series chain hoist, DAVC-A series need less hand-pull force, and they are safer, more beautiful and applicable. DSVC-A Chain Blocks adopt high mechanical efficiency and small chain tension and with chains equipped with latches and protection system for safety and security, this series use double pawl, double guide and are also in the framework style. More safety and hand pull lighter.

DSVC-A Chain Blocks are equipped with the most popular block chain--superior grade 80 load chains and forges and heat treated load hooks with batch traceability and stretch indicators, and 360 degree hand rotation with stroke to ratchet indicators. There are also double  pawl brake linings, forged safety latch and sealed roller bearings. With fine and beautiful appearance and reasonable structure, they are environmental-friendly with stable operation and durable in use and service. DSVC-A Chain Blocks are convenient manual lifting machinery, which are suitable for the short distance lifting of small equipment and goods, and the weight is  generally not more than 100 ton. the chain blocks' shell material is highquality alloy steel, strong wear resistance and high safety performance.

DSVC-A Chain Blocks are innovated symmetrical arrayed high speed synchronous gears, and are made of international standard gear steel. Compared with common gears, they are more wearable and steadier, and more laborsaving. The main components are all made of high class alloy steel, with high precision and security. Adopt advanced plastic plating technology inside and outside, it looks like a new one after years of operations. All DSVC-A Chain Blocks have safe and reliable braking functions with gear case and hand wheel cover resistant to external shocks and double enclosure to keep out rain water and dust for a long lifespan.

Load chain in chain block is one of the most critical parts, the abuse that this chain receives can be the difference in a minor accident or a catastrophe, yet it is probably the most overlooked part of a block. Load chain should be inspected daily, weld spatter, a nick, gouge, or stress can greatly reduce the capacity of the load chain. Please inspect your load chain and make sure you always make a safe lift. What’s more, due to the crushing effect grab hooks have upon chain, the design factor of all assemblies must be reduced by 20% for Grab Hook applications. This is a vital type chain block and there are different models such as VT, VC-A, VC, HS-VT, HSZ-VT, HSZ-A622 for this chain block, all means this vital type.

DSVC-A Chain Blocks are widely applied in factories, mines, farms, construction sites, agricultural production, and in wharfs, docks and storages for fixing machines, lifting cargos, loading and unloading goods. They are especially advantageous for lifting work in the open air and places where no power supply is available.

The chain blocks can be attached to a trolley of any type as a traveling chain block. They are also suitable to monorail overhead conveying system, hand travelling crane and jib crane. Our products are widely applied in household, outdoor traveling, aerospace, warehouse, manufacturing industry and construction industry. VT chain block can also be used with all kinds of  manual single-track driving vehicles, which can be used in single rail overhead transportation, manual single-beam bridge crane and cantilever crane.

DSVC-A Chain Blocks are also called alloyed steel gear DSVC-A manual chain  blocks, good price DSVC-A type chain blocks with forged hooks, hand tools chain block lifting equipment alloyed steel gear, hand operated hoists, Mechanical hoists and Manual hoists. DSVC-A chain block are the hot selling chain block in china market and maybe the most popular manual chain block.

     9. there is no relation for 0.5T and 1T, cause hoist body is different (some northern manufacturers use 1T hoist body  instead of 0.5T since they don’t have 0.5T mould)

           there is no relation for 1.5T and 2T, cause hoist body is different

           7.5T and 10T are made up of 1 piece of 5T body, the difference is chain falls and hook

           20T are made up of 2 pieces of 5T body, the difference is chain falls and hook

           [hoist body= chain block body only( bare  block---without load chain and hand chain)]

           5t, 2 chain falls, 1 body

           7.5t, 3 chain falls, 1 body

           10t, 4 chain falls, 1 body

DAWSON manual chain hoists are commonly known as chain blocks and are designed for heavy duty lifting and materials handling operations. Chain blocks raise and lower loads by pulling on the hand chain. Chain blocks can be of single or double fall configurations depending on the capacity of the block.

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. 
- All rotating components mounted on roller or ball bearings to reduce friction & increase efficiency.
