Electric Chain Hoist Selection

Electric chain hoists a valuable piece of material handling equipment when properly apply.

Below are a few steps to help you lead the right kind of electric chain hoist.

1.Is hoist is in a particular environment? If an explosive atmosphere is class group as a particular environment, and the applicable department. These power specifications that require special enclosures, but you may also be considered are the wheels of brass, stainless hooks, stainless chain, etc. to the need to meet the electrical specifications are not made but sparks Can such mechanical items. Also note that the high humidity, heat, or out.

2.What hoist the duty cycle. How will multiple motor starts? Remember if you pick up a 2 speed motor will start twice. In addition to considering the space elevator. That's why you have to take the series in an area or all lifts will be different lengths. If a lift series is one place in premature failure can do. If the duty cycle is too severe, you may want to consider a wire rope hoist. Variable frequency control to reduce the situation as you do not contactors or the number of motor starts can be a two-speed hoist.

3.What kind of suspension hoist you need? If the hoist at a given point is a top hook hoist will work well with a beam clamp may consider is to be hung. It can be taken when needed. If you or a bridge with a monorail crane trolley you push either a plain or a motorized trolley to travel around the need to consider. A simple push trolley is affordable and not normally a problem with 2 tons of weight down, but it is hard to be a time you can prevent weight gain and it will not brake for a motorized trolley easier than can drift. If you have a large weight, what are braking a few times a day or so you may want to consider a motorized trolley positive needs.

4.Next you specifically need to look to be working. A critical part of setting you down such as the exact needs or you are just routine maintenance or construction. If you run is expensive, delicate or precise hoisting motion takes place so you will want to look at the variable frequency control. If you just need a little precision, consider the two speeds. Americans generally have a 3 1 ratio and foreign hoists hoists a 5 to 1 ratio. So as the top speed of 15 FPM with a domestic hoist 5 / 15 FPM will be. General maintenance or construction of a speed time great works. The same goes for trolley control system. You variable frequency control, two speed or precision you need to see based on the single speed. A trolley brake is also an option to consider.

Hoist hoist motor in a single or three phase power will be offered on the horse power 5.Depending. If you have a heavy application of three-phase power is available it should use. its diverse components such as contactors and motor will run cooler and last longer. If it is a two-speed unit, so be sure and three phase power hoists reconnectable as these are not specified. The 230-3-60 208-3-60 or 460-3-60 as specify.

6.If a bridge or monorail hoist beam and beam size of the type you will need to verify is running on. You need to know if it is a wide flange or I-beam flange width and depth as well. Most manufacturers now take up a wide flange on a wheel to run or walk a thin beam can I offer. In some cases it even patented flange track at which a 3.33-inch or 3.25 inches may be required and special wheels.

7.You know that you get power to the hoist are going to need. Usually a festoon systems, which track type C or tagline can be done with the arch. You can use the bar or a cable reel.

Created a brand that is widely distributed in the United States or have an idea if the 8.Looking down time is an issue. Foreign hoists a broad distribution channel and thus some of the parts take weeks to find or are not hard to get. Wide distributor of many brands in one night so getting replacement parts is the case network.

The above steps will help you a bulge which features you need for your application to the lead.
