Manual Instructions Guide For Electric Chain Hoist are following.
- An Electric Chain Hoist is a electric equipment in which the high capacity Alloy Steel Chain is used as a lifting element to lift the material or object vertically up or down.
- Electric Chain Hoist is used as a stand-alone equipment, used in the overhead crane or jib crane or in Goliath crane.
- LOADMATE Chain Hoists is ideal solutions for a different kind of workstation.
- Electric Chain hoist is preferred over Electric Wire Rope hoist in several cases based on the application.
- Before operating Electric Chain hoist, main component such as brake, switchgear, clutch, remote, hook must be checked well.
Expected Goal:
- Under the normal working condition, the vertical lifting and descending and horizontal movement of electric chain hoist is controlled by pendant push button.
Preparations:
- There will be some risk when electric chain hoist works with the heavy load, especially when it is not properly operated or poorly maintained.
- Due to potential serious accidents and casualties, do remember that safety always comes first when you are operating, maintaining or checking euro serial electric chain hoist.
Instructions for safe use
- Do not use the hoist to lift, support or carry persons.
- Do not operate it close to/over persons.
- Do not lift more than rated load marked on the nameplate of electric chain hoist.
- Always remind the persons nearby of safety before lifting the load.
- Always read carefully safety instructions.
- Do remember that it is an operator`s responsibility to make correct installation and operation. For more documents of safe operation of the hoist, please refer to all relevant safety regulations and other laws.
Characteristics
- Electric chain hoist characteristics motor brake, hook and hook latch, limit switch, friction clutch.
Pre-Operation Preparations and Examinations
- Do remember that only trained personnel should operate the hoist.
- Before using the hoist, ensure to check it according to “daily exam” requirements.
- Ensure that chain is long enough.
- Always check if hook latch can normally work, if not replace the missing one or the damaged one.
- Always check brake before using the hoist.
- Whenever two hoists must be used to lift the load, ensure that load capacity of the two hoists must be more than/equal to the load.
- Ensure to use original chain or the chain authorized by the manufacturer.
- Do check and keep the lubrication of load chain surface.
- Do not use electric chain hoist without nameplate.
- Do not use modified or distorted hook.
- Do not use electric chain hoist in the explosive environment.
During operation Regulations
- Make sure that load correctly lies in the hook.
- Ensure to tighten chain and load sling when starting to lift the load. Do not suddenly add load.
- Do not operate the chain too slowly.
- Do not reverse motor hoist before it has completely stopped working.
- Make sure that the hoist is in service life and operate it within rated load and ED.
- Ensure to operate it after making load center of gravity right underneath the hoist.
- Do not use hoist chain as a load sling.
- Do not use a distorted, twisted or extended load chain.
- Do not shake suspending load.
- Do not support the load with hook tip.
- Do not scrape some sharp edge with load chain.
- Do not weld or cut the suspending load.
- Do not use the hoist chain as a welding electrode.
- Do not operate the hoist when the chain jumps or makes much noise.
- Do not use inverted load chain.
- Don does not frequently use friction clutch and limit switch, otherwise, the hoist will be seriously damaged and can cause harm to the surroundings.
- Do not forcefully push the button cord.
Installation of Electric Chain Hoist – hook suspension
- Choosing chain container
- Chain container is used for containing load chain when the load is lifted.
- Check whether the stopper is correctly fixed on the third link starting from the no-load side chain.
- The stopper with the upper limit switch should be fixed on the sixth link of the load side. The stopper with upper/lower switch should be fixed on the eighth link.
- The chain cannot be distorted or twisted when it is sent from the free end to chain container, otherwise it many touch limit switch and stop the hoist falling.
- In addition, each chain container tells the maximum length of load chain that it can hold.
- It is dangerous to use a chain container which cannot hold the load chain. Only when all load chain is put into the chain container, the limit switch can normally work.
- So it is important to make sure of load chain length before its container is decided.
- Lubricating gear case
- Lubricating load chain
- Checking chain alignment
- Checking cables and working voltage
Installing Electric Chain Hoist & Motorized Trolley
- Installing chain hoist with trolley then must be five item refer to chain container, lubricating gear case, load chain, chain alignment, install trolley.
- Chain hoist connects with chain container, cushion rubber, stopper, chain container suspender, socket bolt, lever nut, chain container spring, plain washer.
Operation Test
- Do not go away when the load is still being suspended and or leave it hanging too long.
- Electric chain hoist Operation test in a different kind of test like lifting test, Traversing Test, Limit Switch Test, Lifting & Falling Brake Test, Emergency Stop Button Test.
- After Hoist packed unboxed first proper check parts match with invoice or instruction manual.
- All proper checking electric chain hoist connect with trolley proper, trolley joins with the beam, bolt-nut-split pin proper tight.
- Lifting test is push button press and checks traveling direction. Limit switch test in upper limit and lower limit switch.
- Lifting brake test button release then stops at time motor. When push emergency stop button then check hook is stopping or not.
Maintenance
- Make sure that it is professional technicians who have a routine check of the electric chain hoist. Electric chain hoist maintenance activity must be note down specific time period.
- Always off power when hoist in repair. After repair hoist must be test load before the main operation.
- Replace oil gear at least five years even if hoist does not use minimum worked hours. If you can use light load then after 360hrs change gear oil, moderate load in 240hrs, heavy loads 120hrs.
- Always keep load chain in lubrication
- Do not extend load chain by connecting, adding or welding.
- Do not touch the electrified components.
- Do not adjust friction clutch.
Breakdown Exclusion:
- The breakdown is a failure, machine stop working.Hoist Breakdown give negative impact on production or manufacturer cycle.
- The breakdown is highest chance generate automatically. But if you can point not down some step follow then 85% fewer chances of Breakdown Generate during working time.
- Electric chain hoist breakdown exclusion must need to troubleshoot fast and make the hoist working again safely.
- Some of the basic breakdown exclusion is electric cable shock, not motor movable, hoist can't stop, hoist can`t lift a load, lubrication oil leaks, load chain noise generate and much more...
ReplyDeleteThis is very nice and informative blog thanks for sharing such like of information.
Electric Chain Hoist
Hi there would you mind stating which blog platform you're working with? I'm going to start my own blog soon but I'm having a difficult time selecting between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design and style seems different then most blogs and I'm looking for something completely unique. P.S Apologies for getting off-topic but I had to ask!
