Chain blocks are portable devices used to manually lift or lower a load. A hand-operated chain hoist is usually smaller and more compact compared to an electric hoist of the same size. Chain blocks are able to lift in a vertical position only. If they are side loaded or used horizontally it is possible for the mechanism to jam.
A come along (also called a wire rope hand ratchet puller) is a manual device that can make moving heavy loads by hand possible.Lever hoists are portable devices used to manually lift, lower or pull a load. A lever hoist can also be used for tensioning and lashing loads for transport. Lever hoists have the advantage of being able to lift in most positions, including horizontally and vertically, where chain hoists can typically only be used vertically.
Lever hoist’s (also known as blocks) have a handle on the side of the block which houses an internal gearing and ratchet system fitted with load chain. A lever block works by cranking the lever up and down to engage the ratchet and pawl system, which causes the load to move a set distance per crank. The direction of the internal gear can be easily switched, to move the load up or down as needed. There is a hook on the end of the load chain for easy attachment to a load, and a hook attached to the housing of the lever block for attachment to secure support (e.g. steel beam).
Benefits Of An Electric Hoist vs Manual Hoists
Hoists are used to lift and lower heavy loads and are valuable pieces of equipment in the construction industry. When choosing a hoist for your lifting applications, it’s important to choose one that is best suited to your operations in the long term.
Not only will you need to think about the amount of weight your hoist will typically be lifting, but you’ll also need to think about the preferred speed and the height you’ll need for the lift. Once you’ve decided this, you should consider whether manual or electric is best suited to your requirements. You should choose a hoist that can cater to both your present and future needs, which is why you should be critical when making your decision.
With a wide range of hoists to choose from, it’s best to start by choosing whether an electric hoist or a manual hoist is better for you. In this blog, we compare the differences between electric and manual hoists and identify the benefits of each so that you can make an informed decision.Chain hoists are an integral part of the hoist family, working to complete lifts using an electric power source. This means that they can lift much heavier loads than manual hoists, with capacities of up to 30 Tonnes. The electric chain hoist is a sensible purchase for various industries and professionals using lifting equipment on a regular basis, or currently completing manual lifts.Once in a while, we require the help of winches to work on some necessary job. We might also need to replace our old winch and buy ourselves a new one. When making such a purchase, we need to factor in many considerations, such as what kind of winch would suit our purpose and benefit us. Let us have a brief look into the differences between electric and hand winches before we explain to you which one is more of your benefit.
