Traditional hand chain hoists are a known commodity within the lifting and rigging industry as one of the most versatile and reliable rigging choices for a variety of different projects. However, much like any other piece of equipment, hand chain hoists have their limitations. That is where a lever hoist can save the job.
Lever Hoists
Breaking down the difference between the two is as simple as looking at the direction the load needs to move. While a hand chain hoist is a great option for vertical and angular lifting, they are not suitable for horizontal pulling. Lever hoists, in this case specifically referencing come-alongs and Griphoists, have the ability to operate both vertically and horizontally with no difference in setup or capacity.
Let’s say you are replacing a load in a facility with nearly no headroom to fit a clamp/trolley, hoist above, or skates below at the final position. The placement needs to be exactly where the old unit was. And the site does not allow for a winch to be anchored into the ground; what do you do? This is a great application to break out a lever hoist.
Come-a-long Vs Griphoist

To start, let’s quickly discuss the difference between a come-a-long and a griphoist. Most often, when people think of lever hoists, their first thought is a chain come-a-long.
Come-alongs operate with a ratchet and pawl that rotates a gear to pull the chain along a straight path. While slow-moving, come-a-longs provide greater precision in load movement than can be achieved with a traditional hand chain hoist. Come-a-longs also allow loads of up to 18,000 pounds to be moved with less than 80 pounds of force on the lever. Since the levers are engineered for optimal safety, it is important to never resort to the use of cheater bars or other means of misusing a chain come-a-long.
Griphoists, also commonly referred to as a Tirfor, operate instead using specially designed wire rope that allows two grip-jaws inside the unit to clamp down on the wire rope. The unit alternates which jaw is activated, similar to a hand-over-hand pulling method. The only limit to the length of pull available with a griphoist is the length of rope available in your fleet or from your local distributor. But remember, you must ensure that the wire rope you are using is designed for use in a griphoist. You can see a quick overview of a griphoist here.
Which hoist to choose?
Now, let’s head back to our load to determine the best course of action. With the bolt-down restriction, the first step is to have an engineer determine the viability of any anchoring points where the lever hoist can be mounted as a base. Provided there is a safe column/structure with a clear line-of-sight, it’s now time to set up your hoist and begin the move. The first step is to determine the force required based on the weight of the load and the coefficient of friction as we’ve discussed in previous blogs.
Griphoists are available in capacities of up to 4 tons (without recruiting sheave blocks that would increase the capacity using mechanical advantages), while a come-along is available in capacities ranging up to 9 tons. If you know the exact force required, you can make an informed decision on which option works best for you between the two. A situation that would have otherwise proven impossible or far more difficult to complete can be handled with ease with the use of a lever hoist.
