Air hoists provide significant advantages when it comes to the heavy duty and heavy production applications. They are particularly more preferable compared to the electric models. Some of the obvious advantages that they offer users include an infinitely variable speed control, an explosion proof design that is inherent in the equipment and a higher duty cycles. They are also relatively smaller in design compared to the electric models.
Buyers generally have wide range of options to choose from when it comes to these hoist designs. Depending on the area of application, customers can choose the spark resistant hoists, the light duty hoists, the standard duty hoists and the heavy duty hoists that are typically applied in the heavy production use. But what are the main determining factors when it comes to the choice of the best quality and most reliable air hoists for your application?
The guiding principle when it comes to choosing the best air hoists for the right job is to look at the specifications. Here are some important specifications that you will need to put into consideration:
The Capacity of the Hoist
This is a fairly obvious consideration. If you are going to purchase a hoist, then it should be of the right capacity for the job. The main consideration here will be the amount of weight that you are planning to lift. The capacity of the hoists can range from a value of 275lbs to 220,000lbs. It is always advisable to give an allowance on the upper side of the weight that you are trying to lift. In other words, the capacity of the hoists should be slightly more than the value of the weight that you are trying to lift.
It is also important to ask yourself whether the hoist that you are purchasing will be put to other applications other than that for which it is being purchased. This is always the case. In that case, it is important to consider a generous allowance for capacity when purchasing the hoist. Try to anticipate the other weights that you are planning to lift and make the allowance accordingly.
This is also a key consideration when you are purchasing a hoist. The lift of the hoist basically refers to the distance in which you plan to lift the object, in the z-axis. All hoists in the market have a standard configuration of 10 feet. But the hoists are also highly customizable and it is possible for you to achieve a lift of up to 99 feet or even more based on the application to which the hoist will be put. It is, however, important to note that the costs will increase with longer chain length in your hoist.
This is another important specification that you will have to put into consideration when shopping for the air hoists. It refers to the amount of the air hose length that has been offered by the manufacturer as part of the hoists control package.
Pay careful attention to both the lengths and the types of controls that you plan to use. Choose the controls that will allow for ease of operation.
The Lifting Speeds
Look for both the lifting and the lowering speeds at which the hoist is operating. These are typically measured in feet per meter of FPM. Logically, there exists an inverse relationship between the lifting speed of the hoist and its capacity. So expect slower speeds for the larger capacity air hoists.
