I have the 2 ton harbor freight chain fall with their ibeam trolley. It lifted all my toolboxes out of my truck when I bought them home. It lifts the generators and snowblower as well. I am lucky to have the ibeams supporting my upper level of the house where my garage is. This summer I had the top half of a 350 hanging from it when I was finishing a Vette. To me it's a valuable piece of equipment. No I am not afraid of something falling because it is from harbor freight. The hoist is identical to my dads cm and the trolley is steel plate and fully adjustable. Both the hoist and trolley are very heavey for what they. I looked at electric, lever, and chainfall types. For me the price and the ability to see it before I bought it made my decision of where to get it. I like the chainfall because you never have to worry about where the lever will be when you are preparing to lift something.

Do you have a job to do but you're not sure which equipment to use? In this article we compare the differences between lever hoists, chain blocks.
What is a lever hoist?
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.
How does a lever hoist work?
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).

The load chain on a lever hoist comes in standard lengths of 1.5 or 3 meters, with working load limits available from 250kg ' 9 tonne. Other sizes available at request.
What is a chain block?
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.
How does a chain block work?
A chain block is operated manually, made from a combination of internal geared pulleys fitted with chain. The user will pull down on the hand chain, this will turn a pulley mechanism inside the hoist to move the load. There is a hook on the end of the load chain for ease of attachment to the load and a hook on top to secure the chain hoist to a suitable support.
Chain blocks are available in either a manual or electric mechanism, with sizes available from 250kg ' 20t in 3 and 6metre heights of lift. Other sizes are available at request.
