Important Checks to perform before using Electric Chain Hoist

Hoists are one of the mechanical systems for lifting and pulling your loads. These devices are not something new to us, and we have found the evolution of technologies in hoist designs and models. Manual, pneumatic and electric hoists are common choices for you. However, some hoists are also available in universal styles.

Modern hoists have made it easy for you to lift heavy loads. As you are using them every day, you have to take safety steps, and the important responsibilities for you is to check out chain hoists thoroughly before using them. These professional checks will help you to make sure that your chain hoist components are performing best. A minor issue may result in a serious accident to the chain hoist user. Thus, you can ask your chain hoist suppliers for the inspection list of the system.

You may have invested in a quality chain hoist to use it regularly for lifting and shifting heavy items. However, hoists do not last forever, and they can start deteriorating in due course. You need to check out the early signs of issues of these hoists. One of the best options for you is to do the regular preventive maintenance of your chain hoist. Timely maintenance helps you in avoiding hoist breakdown and costly repairs. 

In some cases, hoist conditions may become irreparable, and then, you need to buy a new one. We have noticed some common problems of these chain hoists. For instance, a failing brake system can result in a load slippage. The load slipping process will severely affect your productivity and safety. Moreover, broken parts of a system can cause abnormal noises. Surely, every hoist produces noise, and thus, you have to know the nature of this sound. You may find that a dirty chain and worn-out sprocket can emit noise. By lubricating the component, you can solve the problem.

To avoid issues, you must test the performance of your hoist-

Test the lifting mechanism

You have to conduct the test to ensure that the hook of your chain hoist works rightly and the system moves it the desired direction. To start this test, the main switch needs to supply power to the hoist.

When the direction of the hook’s movement is in the wrong direction, your power supply may have a problem. You have to change it without any delay. It can be done by interchanging any 2 phase from the 3 phase connection supply.

Arrange a brake test

Failure to brakes is one of the problems of chain hoists. Although it is a common problem of chain hoists, it can injure others and cause mishaps. That is why you must inspect the brake system to avoid complications in the future.

What should you do for this test? By releasing the load, you have to check how the load stops at its position while the switch is controlled. You can choose moderate loads for this test and ensure your safety.

Test the Cross Traversing motion

The trolley needs to traverse rightly based on your control. You can engage qualified persons to ensure that your trolley moves consistently. The trolley in good condition will be easily controllable.

Certified persons for inspection will check out several other things-

  • Valves, latches, lines and other elements of a pneumatic system for leakage
  • Odd sounds coming out of your hoist and trolley
  • Proper mechanisms of every part
  • Corrosion issues
  • Chain problems- compression, elongation, deformation

Periodic inspection

You need to do a visual and audio inspection to check out hoist and its parts. You can disassemble these parts to identify issues. It is about the monthly and weekly inspection of your hoist. The operator can perform it easily.

For the manual hoists, you have to check out several other parts.

  • Tagged Hoist- Your hoist must not be tagged with an odd sign.
  • Hand Chain Control- The hand chain pull must align with motions of travel directions.
  • Damages to hook- Nicks, cracks, twist, and gouges
  • Hook Latch- Make sure that the latch is not missing.

Always follow guidelines of chain hoist manufacturers.

At the time of installing the chain hoist and preparing it for your use, you have to know the right guidelines. You have to make the proper installation of the hoist, trolley, stopper, and other components.
