All through this informative post we are going to be discussing the properties of the manual chain hoist. We'll examine what they are, where they may be most commonly applied, how they operate, why they could be helpful and some vital safety points for using a manual chain hoist.
From the outset please note that the manual chain hoist is also regularly referred to as a chain block, block and tackle, hand chain hoist or manual chain block.
So what is a manual chain block ? Plainly put, they are a piece of hand operated lifting gear suitable for lifting, lowering and manoeuvering heavy objects at the pull on the chain. How do they work? To begin with they're attached by the use of their top hook to an appropriate fixing point, frequently a beam clamp or beam trolley generally on a jib crane or mobile gantry. As soon as secure the load is attached by the use of the bottom hook often with the use of a sling of some kind, depending on the kind of load, one side of the chain is then gradually pulled down on, which consequently sends the chain revolving about a couple of different sized gears inside the housing system which increases the gear ratio and thus increasing the lifting power. The brake holds the load securely as and when required. The opposite chain is pulled to lower the load. Overload prevention devices may also be integrated for additional safety.
Manual chain hoists are able to have many different falls of chain, they all work in the exact same way, but the more falls of chain the heavier loads they can lift but are slower as a result of quantity of chain that is to be pulled through the gears. The lower the falls of chain the faster they pull through.
Hand chain hoists are available in all kinds of models, with different lifting capacities and many have integrated trolleys to fit directly onto a steel beam. The majority are available with optional extras to assist their versatility; chain buckets/bags enable any excess chain to be held out of the way which provides protection to the chain from damage and also to help you avoid accidents from free hanging chain.
So what are the advantages of using a manual chain block and where are they typically utilised; Chain blocks allow weighty loads to be lifted with much precision, they are easy to move from one place to another, are cost efficient and exceptionally valuable where there is no electricity supply so an electric hoist can't be used, and also where using electricity could possibly be hazardous. The versatility of the manual chain block allows it to be used in lots of places, regularly in workshops, factories and numerous industrial areas.
There are countless safety rules for the safe use of every type of lifting devices which should be issued when buying. Allow me to share the very basic do's and don'ts for a chain block.
On no account; exceed the safe working load; use if defects are noticed or problems suspected; stand beneath a suspended load; tip the load; change the chain without consultation with the provider/manufacturer; lift people.
At all times; check over for defects prior to every use; make sure it is frequently inspected by a certified person (six monthly) use appropriate safe slinging methods; pull chain smoothly; ensure the chain/bottom hook will reach the lowest point without running out the chain completely; fasten load directly beneath top hook, keeping the centre of gravity as closely as achievable.
To encapsulate then a manual chain hoist is very versatile and cost efficient, easy to utilize, in all kinds of areas as well as being easy to inspect and fix if required. A good piece of lifting gear.
