Forklift Mast Chains - Used in various applications, leaf chains are regulated by ANSI. They can be utilized for forklift masts, as balancers between heads and counterweight in some machine gadgets, and for low-speed pulling and tension linkage. Leaf chains are at times also called Balance Chains.
Construction and Features
Leaf chains are actually steel chains using a simple link plate and pin construction. The chain number refers to the pitch and the lacing of the links. The chains have particular features such as high tensile strength per section area, which enables the design of smaller mechanisms. There are B- and A+ kind chains in this series and both the AL6 and BL6 Series comprise the same pitch as RS60. Lastly, these chains cannot be driven utilizing sprockets.
Selection and Handling
In roller chains, the link plates have a higher fatigue resistance because of the compressive tension of press fits, yet the leaf chain just has two outer press fit plates. On the leaf chain, the most acceptable tension is low and the tensile strength is high. When handling leaf chains it is vital to consult the manufacturer's instruction manual so as to ensure the safety factor is outlined and use safety measures always. It is a great idea to exercise utmost caution and use extra safety measures in applications wherein the consequences of chain failure are severe.
Higher tensile strength is a direct correlation to the utilization of a lot more plates. Because the utilization of a lot more plates does not enhance the maximum permissible tension directly, the number of plates could be limited. The chains require regular lubrication because the pins link directly on the plates, producing an extremely high bearing pressure. Utilizing a SAE 30 or 40 machine oil is frequently suggested for nearly all applications. If the chain is cycled over 1000 times every day or if the chain speed is over 30m per minute, it will wear really fast, even with continuous lubrication. Thus, in either of these conditions using RS Roller Chains would be a lot more suitable.
The AL-type of chains must just be utilized under particular situations such as if wear is really not a huge problem, when there are no shock loads, the number of cycles does not go over a hundred every day. The BL-type will be better suited under various situations.
The stress load in parts will become higher if a chain utilizing a lower safety factor is chosen. If the chain is likewise used amongst corrosive conditions, it could easily fatigue and break very quick. Performing frequent maintenance is really important when operating under these types of situations.
The outer link or inner link type of end link on the chain would determine the shape of the clevis. Clevis connectors or otherwise known as Clevis pins are made by manufacturers, but the user usually provides the clevis. A wrongly constructed clevis could decrease the working life of the chain. The strands must be finished to length by the maker. Refer to the ANSI standard or phone the producer.
