The electric wire rope hoists lift up heavy objects by coiling the rope around the drum, driven by an electric motor to make the work of lifting heavy objects easily. There are a number of electric wire rope hoists in India from where you can get your wire rope hoists to benefit your work. While you are obtaining from efficient electric wire rope manufacturers, you can be guaranteed about to develop the electric wire rope hoists. Around 78% of construction companies and large scale manufacturing industries utilize industrial wire rope hoist cranes.

Acquiring from electric wire rope hoists manufacturers, you should consider some elements such as quality, stability, viability and easily preserve. In this purpose, you are required to discuss the requirements with wire rope hoist manufacturers, so that they can integrate all the essential features into the machine to satisfy your needs.

It is always reasonable to adopt for the electric wire rope hoists that make your work easy-going. These machines are usually packed with abundant horsepower to assurance that the machines can lift even the large resources without stress. Standard wire rope hoist comes with a 6-meter lift.

There are various types of electric wire rope hoists are available

• Stable position wire rope hoists– Designed for basic installations where the hoist will be in a static position, most can be enhanced to feature a trolley at a later time
• Monorail wire rope hoist– Created to travel horizontally attached with power motors.
• Monorail hoist with twin trolleys– Monorail twin with twin trolleys type U are especially designed for heavy objects as well as long hook paths. Safe operating load range between 6.3 tones and 25 tones.
• Standard resist unit– This type of hoists are designed for the medium SWL implementation between 1t to 63 t. The hoist trolley of this crab unit looks two direct drives cross-level motors.
• Extreme low headroom crab unit– It is indicated by ultra-low headroom and with an SWL of up to 40 tons. The expressed end carriage connects positive contact of four wheels with the track.

Control Features Of Wire Rope Hoists

Operating and handling cranes and hoists is a really tricky thing. Controlling such big machines is a complicated task. Wire rope hoists require specialized training to operate and handle. Variable frequency drives control the rope hoists. These controls offer precise movements even when there is a requirement of handling delicate items. Wire rope hoists are accelerated and decelerated to reduce load sway. The EOT crane manufacturers in Ahmedabad explain that controlling the machines require an in-depth knowledge of all the operational buttons. The operators need to be trained for the functions.
Let’s have a look at the control features of wire rope hoists.

Sway Control
A load experience some inertia when the travel buttons are turned on and off. Depending on the weight of the load present on the hoist, the travel buttons needs to be operated wisely. The way the load is hung on the hoist also matters when the load is being transferred to some other place. The speed of trolley or bridge also needs to be maintained and taken care of.
Sway controls are known to correct the amount of inertia that the load will face. These are used to anticipate and control the inertia for the safety of the load.

Shock Load Prevention
Shock loading means when you try to load something that couldn’t be handled by the hoist. The hoist senses it when the lift is loaded too heavily, and it started abruptly. The wire rope hoist can detect and signal when a mould is hanging away from the crane or say is not correctly attached.
The shock load prevention feature slows down the hoist whenever there is some issue with the weight or the way it is loaded on the lift. Since shock loading can damage the wire ropes of the cranes and make the crane structure disintegrated, shock load prevention is a great feature to look into a wire rope hoist.

Hoist Synchronization
When there is something too big to lift, more than one hoist is required. The hoist synchronization features make it possible. The cranes that have multiple hoists can safely lift something bigger with the hoist synchronization feature without worrying about any damage.

These features can prevent damage to the crane and load by creating balance with the machine. The features correct any issues associated with the hoist and weight. If used properly, the functions can prevent even some dangerous safety hazards.

There is a simple rule; everything will last longer if proper care is taken. Everything in the home or at workplace needs to be used appropriately and handled with care to increase its lifetime. The same implies with rope hoists too. Electric wire rope hoist manufacturers  give you some tips on how to store and handle wire ropes to keep them in good condition for a longer time.

Handling of wire ropes

Kinking and springing of cords are very difficult to remove, and the worst thing is it affects the rope life adversely. Proper handling and coiling of cable are necessary to make it ready to be used efficiently and keep it working fine. For the ropes that come on the reel, mount it on the shaft, and you can easily do your job as the reel rotates. Turntables must be used for larger coils to use and cover them back efficiently.

Kinks and how to deal with them

Kink is the most common and one of the most irritating things with wires. It is very easy to come but doesn’t go smoothly. Sometimes, a loop of rope is formed while coiling and as soon as the string is stretched from either ends tightly, the loop tightens and turns into a kink. However, once created, kinks are not easy to remove, but turning the rope to opposite direction can help.

Inspecting the wire ropes in use

To find broken, corrode, and weak quality ropes, inspection is necessary. Things like reduction in wire diameter should be thoroughly investigated to determine the cause. This usually happens due to excessive wear of outside wires. The number and distribution of broken ropes should also be taken into account. Lack of lubrication can also cause corrosion of inside worse which should also be checked.

How to take care of ropes

1. To avoid deterioration, don’t store the rope in open or damp place.
2. Handle the wire properly while uncoiling and unfeeling to prevent kinks.
3. Cutting the ropes before they are sized can lead to loosening of lays.
4. Use ropes that are suitable according to the size of your pulleys and drums.
5. Avoid overloading and sudden jerks. Always keep in mind the safe working load for your ropes as it can also affect your equipment.
6. Timely lubrication of ropes is necessary.
7. The condition of pulleys, drums, rollers, and sheaves must also be maintained well to keep the ropes in better condition.

What’s the perfect time to change the rope

The rope must be replaced when:

1. When within one lay, the number of broken is more than 10% of the number of outer wires.
2. When outerwear of wire is greater than one third of diameter.
3. When the loss in the metallic area exceeds 10%.
4. When the loss in the strength of wire exceeds 1/6th of the total strength of a new piece.
5. When you notice enough preening and loosening of wires due to corrosion and drying.
6. When deformation or distortion of words occur, and the affected part can’t be removed by cutting.

It is mandatory to do the final checks before we take electric chain hoist into implementation. Because it is always good to keep precaution to avoid any disaster. Well, the electric chain hoist has some really great tips to check out before the usage.

We have listed the imperatives below:

1. Preparations

Keeping instruction manual handly will save your time and keep you safe. Reading the manual carefully is one of the imperatives you shouldn’t miss. Also, make sure you have completed all the steps in a correct manner and all the parts are fixed properly.

You can prepare for some questions and check the same with the configuration of your chain hoist.

For the operators/workers working in the workstation should match some checkpoints such as:

• If the electric chain hoist is installed correctly
• The location of trolley stopper is correctly located on the beam
• Whether the bolts, nuts, and split are tightened
• Is cable support strongly fixed over the support arm?
• The push button cord wire and pulling force support happens on controller suspension?
• Also, it is very important to check if the cutoff power source or breaker switch before repairing any machine parts

2. Lifting  Test

Lifting is the main task of chain hoisting where we can not leave any single mistake. In the lifting preparation, one should connect the main power switch to the hoist and press down the push button switch first.

Followed by the constant check on-hook button. That is to check if the hook button travels in the wrong direction if so consider the power supply phase is not in the correct manner.

Therefore, cut off the power source and exchange any two phases of the three-phase power at the hoist and observe the traveling direction of the hook. It would be in the right direction and towards the push button direction.

3. Traversing  Test

Traversing plays the vital role in electric chain hoisting. Where you need to test it before the final execution. Check if the control over trolley holds the same direction while traveling or not. Also, make sure pasting the E/W or N/S on push buttons.

4. Limit  Switch Test

Here the referring of nameplates AB or AC where we can set the upper limits and lower limits. Attaching them on the hoisting is important to show the status of the limit switch. If the nameplates are not mentioned means the status is not clear of a limit switch.

There can be mainly two types of limit switches:

(a)  Upper Limit Switch

(b)  Lower Limit Switch

5. Lifting & Falling Brake Test

Lifting should start with a moderate weight and not the too heavy at the very first test. Pressing down the push button switches to lower or descending hook many times will start the lifting. In which, the release of the button should awake the brake to stop the motor from running and weight should stop on the respective position.

6.  Emergency  Stop Button   Test (optional)

This one is the optional testing segment but important to look at. Because there is no certainty about the emergency. Press down the emergency stop button at the time of pressing down the push button switches and check for the hook if it stops the running. Also, the working of the hoist in line with the push button switch should be tested.

Also, keep emergency button to the right direction and release after it pops out followed by repeating the operation. If anyone step fails then check the essentials and stop the button.

Installation tips that made Wire Rope simpler:

• Make sure to check the length of each rope. This can be found on the installation layout. It is also a good idea to count the number of ropes.

• The diameter of the rope is also something that should be noted. There will ideally be a crosshead data plate on the top of the car which should show the diameter of the rope. Alternatively that diameter can also be measured with the help of a calliper or micrometre.

• Other important factors include the stranding and construction of the rope. Stranding in this context considering the number of strands per rope and the number of wires per strand. For example if there is an 8 strand rope with 19 wires per strand then the wire has a 8 x 19 stranding.

• The wire rope hoists also differs when it comes to the lay. The lay of the rope can be right regular or even right Lang.

• Depending on the application of the hoist you may want to check the grade or tensile strength of the rope. The higher the strength of the rope, the higher the grade. High grade ones are often used on high rises. These may also be useful in high speed hoisting conditions.

• The breaking load can be found on the cross head data plate. The breaking load can range from several values; for e.g. it could be 6550 kg or 14500 pounds.

Maintenance of Wire Rope Hoists

• When transporting reels, it is best to do so by rolling on a flat surface. Alternatively it can also be lifted from a pipe in the reel center hole.

• When kept for storage purposes it is necessary to make sure that the wire rope hoist is protected from moisture, sunlight, and even dirt or dust.

• Special care is required while unreeling the wire rope hoist; in addition to which kinking or dragging the wire rope hoist over a shape edge that can damage it, should be avoided.

• It is advisable to make use of splices when installing the wire rope hoist. This will help prevent the wire rope hoists from rotating.

Conclusion:

Although operating a Wire Rope Hoist is not very hard there are few important pints to keep in mind when doing so. Always make sure the wire rope hoist is functioning fine and is in perfect working condition prior to using it. Never use more load than what the hoist is designed for and never lift any kind of load over people.

It always pays to be aware about everything there is to know about Wire Rope Hoists like:

• Wire rope fittings
• Wire rope machinery
• Wire rope testing
• Wire rope capacity
