Generally, a chain is bent in transverse direction only. On the other hand, a 3D Bending Conveyor Chain is usually structurally bent not just horizontally but in addition vertically. It is actually used for any conveyor line which moves vertically and adjustments in route.
X Form Chains for Trolleys, and Electrical power & Free Conveyors
X-type Chains are applied for trolleys, and power & free conveyors. They are drop-forged rivetless chains featuring high strength, lightweight and easy removal of components. The bottom left photo shows an X-type Chain employed as a trolley conveyor with only one rail.
The bottom right photo shows an X-type Chain employed for a power & free conveyor. An additional rail is installed to receive the load for higher transfer capability.
A power & free conveyor generally has a so-called stop and go function to connect and disconnect conveyed materials with and from the chain, so that the conveyed materials might be temporarily stopped, mixed and stored.
Three kinds of X-type Chains are available according to required strength.
Z-type Chain for Light Load Trolley Conveyors
A Z-type Chain for trolley conveyors is applied for service similar to that of X-type Chains described on the previous page, but is suitable for light loads. It can be widely utilised in conveyors supplying parts, and devices for storing and unloading parts on automobile assembling lines.
Z-type Chain for Light Load Trolley Conveyors
A Z-type Chain for trolley conveyors is used for service similar to that of X-type Chains described on the previous page, but is suitable for light loads. It really is widely utilized in conveyors supplying parts, and devices for storing and unloading parts on automobile assembling lines.
FH Style Chain for Freeyor
An FH Variety Chain is utilised for the same purpose as an X-type Chain and Z-type Chain. While X-type Chain is designed for heavy loads and Z-type Chain is for light loads, FH Type Chain is utilised for intermediate loads. While X-type Chain and Z-type Chain might be vertically bent only slightly, FH-type Chain is 
usually bent both vertically and horizontally, which makes it suitable for any conveyor line moving vertically. We manufacture three kinds of FH-type Chains different in pitch.
Towline Low-Selec-Tow Chain
A towline conveyor has a mechanism to convey dollies caught by a chain buried in the floor. Our chain for towline conveyor is called LST chain (Low-selec-tow chain).
LST Chain might be bent horizontally and can also move on a slight incline. It can be made by forging, and a recess for hooking a dog is formed at the center of each link.
