A chain is an assembly of two or more connected links, typically made of metal. It is flexible like rope but rigid, linear and load-bearing in tension.
Chains are classified be their use and design:
Tie down or cargo control chain is used to secure a heavy load to a vehicle.
Tie down or cargo control chain is used to secure a heavy load to a vehicle.
An anchor chain is a heavy chain that connects the anchor to the boat or ship. The other end of the chain is secured to the ship’s structure by a rigging hardware which enables easy slipping of the chain to sea. The chain is heavy and abrasion resistant from coral, sharp rocks, or shellfish beds.
Large ships use only chain for connecting the vessel to the anchor, but smaller ones use a combination of rope and chain to save weight. A combination rode should be arranged in a way that the rope part suspends in water (and not be in contact with the sea bed).
This chain is suited for using in bucket elevators. Bucket elevators transport large masses of bulk material vertically and use two chain to carry the bucket.
A 3-meter chain with a bend grab hook easily used to secure a heavy load to a vehicle.
A compensating chain is used to counter-balance the weight of the hoist wire ropes. This would create an equal distribution of the load on motor and the drive sheave, regardless of the car’s position in the hoistway.
In full plastic compensating chain, the PVC layer reduces the chain’s noise and corrosion.
Grade 80 chain is heat-treated alloy steel designed for tie down applications and overhead lifting. It is the most economical chain suitable for overhead lifting (of three grade: G80, G100, G120).
Load chains for manual and electric chain hoists
A compensating chain is used to counter-balance the weight of the hoist wire ropes. This would create an equal distribution of the load on motor and the drive sheave, regardless of the car’s position in the hoistway.
In plastic coated compensating chain, the chain is wrapped by a PVC layer which reduces the noise and slows down the corrosion of the chain.
Roller chain (or bush roller chain) consists of cylindrical rollers hold together by side links. It is driven by a sprocket (toothed wheel) and is commonly used for transmission of mechanical power on of agricultural and industrial machinery, including conveyors, printing presses, wire- and tube-drawing machines, bicycles, motorcycles, and cars.
A compensating chain is used to counter-balance the weight of the hoist wire ropes. This would create an equal distribution of the load on motor and the drive sheave, regardless of the car’s position in the hoistway.
In rope-retaining compensating chain a hemp rope is threaded through the chain. The hemp rope reduces the chain to chain collision noise and friction.
Slaughterhouse chain is used to move trolleys in slaughterhouses. Since slaughterhouses are sterilized and humid, the chain should be stainless steel or galvanized and resistant to oxidation.
