Dos and Don’ts of Leaf Chain Anchor Bolts Leaf chain systems consist of a rollerless chain consisting of link plates and pins. It is the simplest form of steel chains used in a variety of handling and lifting applications such as forklift trucks and telehandlers
or any other kind of hanging, balancing, or motion transmitting uses. This system offers greater tensile strength over roller chains while making use of sheaves rather than sprockets. The anchor bolt design
used in leaf chain systems forms a significant part of the entire assembly. However, there are certain
design constraints and considerations you need to keep in mind while designing an anchor bolt for use with a leaf chain.
Don’t dismiss standardization Although a manufacturer can incorporate slight dimensional changes, it is advisable to designing and
producing slots and holes as shown in ISO4347. This ensures flexibility of options in case you think of switching suppliers or a brand of leaf chain fitting for replacement. Don’t use elongated leaf chain irresponsibly
The parts of the leaf chain system are prone to wear and tear just like any other line system with time.
Consider limiting the range of adjustment to elongate the life of your chain system. For convenient adjustment, consider the area of your chain undergoing articulation (read wear) and keep the available adjustment length below this figure. Do consider the size of the thread
Size including thickness and length of your thread matters. Usually, bolts with coarse and rough threads
have a larger pitch which is generally specified for most applications. If any application requires finer adjustments, needful adjustments are made such as for increasing strength by a few units.
