Speed-sensitive applications call for the use of electric hoists, but again, there are a number of considerations to take into account before using one. Here is all the information you need to know while utilizing an electric chain hoist, from environmental conditions to power levels.
Important Things to Consider About Electric Wire Rope Hoist
Power
The power needs, depending on the capacity of your hoist, are one of the most crucially significant factors to consider when buying an electric chain hoist. The job site is wired for what type of power? Your options for electric hoists are constrained to lesser capacity hoists if your site is only wired for 120 volts.
Power needs to be increased to a minimum of 230 volts but can even be connected to 460 volts when purchasing an electric chain hoist capable of lifting higher loads (over 2.5 tonnes). Once you are aware of what you have, you can decide whether any extra equipment is required.
It’s also crucial to make sure the mini electric hoist receives steady, adequate amperage. The extension cord is far too frequently overlooked, despite the fact that the incorrect gauge or length can entirely halt a lift. Make sure you have the right power source for your electric chain hoist by looking at the associated figure.
Duty Cycle
The duty cycle of your hoist is the next factor to take into account for your project after you have determined the appropriate power needs. The duty cycle for many electrically driven equipment pieces is 25%.
For those who are unaware, a duty cycle describes how long a piece of equipment can run for a single hour. This implies that an electric chain hoist with a 25% duty cycle can only operate for a maximum of 15 minutes before needing to cool down.
If a project you are managing calls for a mini electric hoist to routinely raise and lower commodities or equipment, you must decide whether that is the best course of action or whether you should take the time to strategically plan your lifts.
Speed
The next key factor to think about in relation to the aforementioned duty cycle is how quickly the hoist really elevates a weight in comparison to the height of the lift, which is a frequently overlooked issue. Let’s imagine you’re lifting something 60 feet in the air using a 5-ton hoist.
With a lifting speed of 11 feet per minute, you are utilizing little more than 5 minutes of your duty ratio to elevate the weight for one lift. Will you require over three lifts in an hour, or will that hoist suffice?
If you would need to make multiple trips, your choices would be to either construct a second hoist or, if it were possible, slowly decrease to a hoist with a lesser capacity and reduce the load while speeding uplifting. Your hoist plan could assist the project go off without a hitch by including the height of the lift, the pace of the lift, and the timing of lifts.
Mounting Technique (Headroom)
The type of mount that is needed is another factor to think about. What is the greatest choice for you out of the two top options that are available—hook top and trolley top—depending on the hoist model?
There are hoists constructed with a trolley mount top that not only reduces the headroom snapped up by the hoist itself but also eliminates the headroom swallowed up by the independent trolley if you have headroom limits and require a trolley for your electric wire rope hoist.
Even if that option is only accessible in a handful of capabilities, it can be the best choice for your project if time is of the essence.
