When exploring chain come alongs versus chain hoists, we’re comparing two devices made to pull and lift heavy loads. Both devices operate manually and help make handling and towing loads manageable. The benefits of manual hoists are that they’re portable and cost-efficient. Hoist devices are primarily used in the industrial and agricultural industry but are also DIY friendly for small business owners. The difference between chain come alongs versus chain hoists lies in how each tool operates to lift a load. A come along, or lever hoist, lifts a load using a lever and can move items horizontally or vertically. A chain hoist, also referred to as chain blocks, lifts a load through pulling a chain and can only move objects vertically. In short, come alongs can manage heftier loads than standard chain hoists. It’s important to examine the mechanisms of each device to understand how they differ and why they suit different lifting jobs. Explore chain come alongs versus chain hoists.
A chain come along, or lever hoist, is a hand-operated device with similar features to a chain hoist. A come along is an advanced pulley system with chains and gears operated through a lever. A come along device functions with a friction disk attached to a ratchet wheel with a double pawl system. Pawls, the lever that connects with the teeth of a ratchet, prevents the wheel from turning in the wrong direction when pulling the lever.
The main advantage of operating a come along is that it can be operated with one hand. A chain hoist requires both hands to pull on the chain, whereas a come along only requires pulling a lever. A standard come along contains two hooks at the top and bottom of the device. The hooks are swiveling or sling hooks for easy access. The bottom hook is where you attach the come along to the load, and connects to the chain located through the shaft of the tool. The top hook of a come along requires anchoring before mobilizing a load.
The two most significant features of a come along is the directional switch and the retaining pawl. The directional switch is on the body of the come along. The directional switch is how you operate the device to lift, lower, or spool a load. The directional switch features are up, down, and neutral selection for raising, lowering, or spooling loads. The retaining pawl is also on the body of the come along. The retaining pawl is above the grip ring of a come along. Pressing the retaining pawl releases the grip ring to adjust the chain or place it in a neutral position as needed.
A chain come along is primarily used for pulling loads in multiple industries. The advantage of using a come along over a chain hoist is being able to manipulate the direction of pulling the load, whereas a chain hoist only permits lifting a load up or down. Below are some of the most common uses for a chain come along.
A chain hoist, or chain block, is a pulley system made to lift loads vertically. Chain blocks double the pulling force when lifting a load and are sold with varying lifting capacities. A chain block has multiple gears and two primary chains. These two chains are the hand chain and the load chain. The hand chain is what a user pulls on to operate a chain hoist. The load chain attaches the chain hoist to the load itself. The manual operation of a chain hoist allows minimal labor in pulling the hand chain to lift heavy loads.
Inside a chain hoist device, there are multiple gears that multiply the force applied by pulling the hand chain. When the hand chain is pulled on a chain block, the energy turns the main cog through a driver shaft. After converting energy through the driver shaft, the friction plate and internal gears apply force to the primary sprocket that powers the load chain. The main cog operates on the driver shaft that’s secured between a small gear and a pair of larger gears. The pair of larger gears increase the power required to rotate the driver shaft. The larger gears have smaller gears attached to them and connect to an even larger gear that transfers power to the primary sprocket connected to the load chain.
The hand chain webs through the slots on the main cog. The internal gears activate and begin to turn when pulling the hand chain. When the main cog turns, the driveshaft presses downward until the cog pressed against the friction plate of the ratchet wheel. The internal gear, friction plate, and ratchet wheel simultaneously move to operate the lifting process. While pulling on the hand chain, a lever or catch mobilizes through the teeth of the ratchet wheel. The lever or catch prevents the main cog from moving backward when lifting a load.
When you pull the hand chain on a chain hoist, multiple internal gears move in synchrony to magnify the force and vertically lift a load. Chain hoists are useful for managing a load that originally requires multiple people to lift. The chain hoist is a versatile device because if you attach an object to the hook of a chain hoist, it only requires one person to operate the hand chain for lifting the load. Below are the most common uses for a chain hoist.
Devices like chain come alongs and hoists simplify lifting loads that typically require the strength of multiple people. Before selecting a chain hoist, it’s important to evaluate the kind of task you have, and which mechanism suits it best. The best way to learn more about these chain devices is through a supply company like Manufacturer Express.

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.
