Mobile electric hoist and fixed electric hoist comparison

 Have you ever wondered what the difference is between a fixed electric hoist and one that is mobile? The differences are actually very minute. Although there could be substantial differences in the type of hoist that is used for the different operations at your facility, the difference between a fixed and mobile hoist are very simple. One that is fixed is used on a gantry crane that is not going to move the other is used on a mobile gantry crane that can be moved to different locations. There are some other differences that need to be noted, information that is essential that you are going to choose the right one for your business. The following information will go into detail about these differences, helping you to make the right choice.

Electric hoist

Why Gantry Crane Matters

The hoist that is used on a gantry crane is literally the power behind the device. Using differentials, hydraulics, electric motors, and even the pneumatically powered ones, it’s all about how much power you actually need. For example, the larger gantry cranes that are used could be a container crane which you will often see at ship yards. They are capable of lifting hundreds of times using the hoist that is installed. Ones that are very powerful such as a full gantry crane do not even need to use counterweights, yet due to the power of the hoists that are used in tandem, they can lift thousands of times.

Why You Would Need A Mobile Electric Hoist?

There are mobile gantry cranes that have a hoist that is installed at the top. These are used in both indoor and outdoor operations. For example, if you have ever seen one of the enormous rubber tired gantry cranes that are operated on railroads, and also where container storage is the primary focus, these mobile units) are rolled around to the locations where they are needed. Smaller units can be found within factories and most notably a garage where engines and vehicles are worked on regularly. This is where the mobile electric hoist will be used, attached to these mobile units, taking it possible for them to lift items that are at different locations.

Electric hoist

Should You Have Both?

There is actually no reason to get to different types of electric hoist, unless you need to have multiple ones at your facility. Most of the mobile units can be locked into place once they have been rolled into position. Therefore, you have the best of both worlds with the mobile unit that can move, and after making adjustments, it can be completely stationary. The main focus is how much weight can lift, and how much will it cost, when determining where to buy it.

As you can see, the only difference between a mobile and fixed electric hoist is determined by what they are operating on. Fixed ones may actually be installed directly onto an overhead beam, whereas mobile electric hoist are used on portable gantry cranes that are rolled and then locked into position. The cost is going to be determined by the power of the hoist itself, and the gantry crane that is used. All of these things can be examined on well-known websites where electric hoists are sold on a regular basis, allowing you to make a quick decision.
