Electric and manual hoists are compared in this publication.Their uses, advantages, disadvantages and attributes will also be discussed.The variety of lifting equipment available means that there is one suitable for most tasks.
To give just a few examples, they are used by many industries, including forestry and agriculture, docks, production plants, the automotive industry and construction sites.In many cases, a crane is usually used because the load is too large or too heavy for an individual or an individual, or because it is too dangerous.Another reason to use the crane is to speed up the lifting and handling process, so it is usually cost-effective.
Now let\'s take a look at all kinds of lifting machinery.The first is the type of power;You can find the electric hoist, which is obviously driven by electricity, while the air hoist is driven by pneumatic air.You will find that there are two key types of lifting equipment to drive;These are electric hoists and air hoists.
Air hoists are usually used where electricity is not available or inaccessible.However, the air hoist requires a pneumatic air supply to work properly.It is usually used in car garages, oil industries, paper mills and other industries where electricity can cause fires.
If a large amount of air tools are used at the same time, the air hoist may be more economical, since the cost of operating 20 air power tools from 1 air compressor unit is lower than the cost of running 20 electric hoists from 20 independent power outlets.The air hoist also has a working level of 100%;They are very tough and have a very long service life;Since only air is used, they are simple to maintain, but they will be limited to where they can be used because they are permanently attached to the air compressor by hoses.Electric hoist is a very popular lifting equipment.
It only needs one power supply to operate.Unlike air hoists, these lifting equipment are portable;So it can be used almost anywhere.It is usually hung on the beam clamp or trolley on the boom crane or mobile gantry to facilitate more movement;Just press the switch on the pendant remote control and you can leave;The lift becomes safer, simpler and faster, with many different lift abilities from a few hundred kilograms to a few thousand kilograms, there will be something that can be used for most purposes, of course, just have the power.
The manual hoisting equipment will be considered in more detail next.Manual hoist and lever hoist are two of the most extensive lifting machines that do not require power supply.Because of this, they are suitable for most areas and can be easily moved from one location to another.
Manual chain cranes/chain blocks are usually noticed on mobile gantry cranes or boom cranes, but can be connected from simple hooks as long as it can withstand load weight.This is to increase the load by pulling the chain down, because the chain provides power through the gear and keeps the load in a certain position through the brake system.By pulling the opposite chain, the load is reduced.
This hoist has a special model, which can be used from any angle due to its 360 degree mechanism.The manual chain hoist will lift very heavy objects to different heights depending on the length of the chain.The ratchet lever lift is not only used to lift objects, but can be pulled and stretched in almost any position.
The lever lift works by turning the handle/lever up and down, and the chain passes through the ratchet and claw device to lift, pull or tension.Most Ratchet bar lifts use a free-link system, which allows the chain to be pulled out without limiting the length required to connect to the load.The ratchet Rod riser is ideal for precise placement in small spaces and is designed specifically for matching operations.
These cranes are often used for the placement of heavy equipment, to tighten the utility wires, to set up the pipes, to lower the manhole, to maintain the position of the object while working, and even to pull up the stumps.Countless industrial zones use lever lifts like the forestry and garage industries.In a word, it is clear that every lifting device described has good benefits and is likely to have some shortcomings, but these will depend to a large extent not only on where they are being used, but also on the type of application they will be used.
Obviously, electric hoists need power, which may limit where they are used, and there will be some operating costs, although they do be able to do the task faster.There is no operating cost for the manual hoisting system, but it is only a little maintenance from time to time;Some manual hoists are able to lift, pull and tighten from any position.Since there is no need for power supplies, they can be used almost anywhere.
