Various Types Of Gate Wheels Systems

There are various varieties of sliding gates and gate wheels plus track types that a sliding gate can operate along. Most common are channels or rails where the rails can be round or rectangular. The track could be basically a groove and gate wheels could also be of a v-groove type situated at the foot with the fence.

Gate Wheels

 You'll find gate wheels that act equivalent to trains and train tracks whereby there's a groove down the centre in the gate wheel keeping it on the wheel track. This is the most stable and reliable configuration. When operating it truly is critical to look after your fingers along with other limbs as these gates are very heavy and could cause serious harm.

Electric gates are much more prevalent on industrial or large company premises as well as mansions where the owner has complete control as to who enters onto the property. Together with the aid of a remote control device the electric gate barrier will move backwards and forwards with a push of a button to permit access and exit to the premises.

Electric gates with gate wheels and remote controls enable the owner to obtain entry with out exiting their car and these type of heavy duty gates are regarded as extremely secure. A lot of people favor this kind of electric gate wheel method, because of its ease of use. These gates wheels systems are classed as state of the art security.

Gates Wheels Wear Out Over Time

Like any moving object the moving gates are exposed to wear and tear and can be damaged over time. The most prevalent damage occurs to the motor or gear box, but also the gate wheel area. Keep a keen eye on the track area of a gate as often debris can get caught in the track causing a malfunction to the gate system.

It truly is importantly essential to often maintain the gate wheels system and keep it clean of stones and debris that could possibly been blown onto it. More often than not using a leaf blower is an excellent way to keep the tracks free of leaves and small twigs.

Choosing the right gate motor for your gate wheels system is very important. A motor that is specified lower than the weight it must move, will burn out quickly. Be sure to know exactly how much force it takes to move your gate.

You can then calculate the power needed by the motor to move the gate along the track. Remember the gate should move easily without binding before taking this force measurement of the gates wheels system. If you are having your gate wheels system installed, the contractor will ensure to pick the correct motor size for your gate system.

Trolley Wheels Selection Process

 

 

Your Trolley Wheels Checklist

When it comes to specifying the right trolley wheels for your application, you must take it very seriously or you raise the risk of buying the wrong trolley wheels. There are many factors that must be evaluated before you make your final selection.

Trolley Wheels SelectionFirst is the load that the trolley wheels will be subjected to. Standard rule is, the heavier the load, the larger the trolley wheels have to be. There a few reasons for this, most importantly is it is very difficult to move heavy loads with small trolley wheels.

Also if trolley wheels will experience over 400 pounds of load, the trolley wheels will need to have ball bearings in the design, For loads this heavy, the friction on the shaft of the trolley wheels would cause early life failure. Ball bearing trolley wheels must be used for heavy loads.

Another factor that affects trolley wheel diameter size, is the floor condition. If floors have large cracks, small trolley wheels will not work well. They tend to get stuck in the cracks of the floor. Say for instance, there were cracks in the floor up to .250 inches. This would cause great difficulty for trolley wheels up to 2 inches in diameter. Same goes with uneven floors that might have raised boards. Small trolley wheels will not work in this instance either.

 
Trolley Wheels Materials Explained

Now let’s talk about the material to be used on trolley wheels. Each material has characteristics which will provide the best results for different environments. For instance polyurethane, polyolefin, phenolic, or steel wheels are best when the trolley wheels are exposed to acids, oils, or chemicals.

Rolling Ease is another factor. If by chance, your main concern is how easy it is to push a trolley under heavy loads, then you must follow this. The larger the trolley wheels, the easier your trolley will move. Also the bearing type used for trolley wheels is also important. Roller bearings are used for heavy loads and ball bearings are used for light loads.

Have you thought about extreme temperatures? Room temperatures are not a problem for most trolley wheels. However extreme cold and heat can lead to problems. This is where bearing lubricants come into play. There are certain lubricants that protect bearings under extreme temperatures.

Shock load is another area to review for trolley wheels. If your trolley wheels  will experience sudden load from dropping items into the trolley, you must be cognizant of the trolley wheels design to withstand the shock loading. Many trolley wheels designs will collapse under sudden shock loading.

Now to trolley wheel types. A rigid trolley wheel caster is one that permits only straight line movement with no swivel ability. These are used when you want your trolley to have two trolley wheels that swivel and two that don’t. For swivel trolley wheel casters, they have the ability to swivel a full 360 degrees.

Additionally the trolley wheels should have locking mechanisms on at least 2 of the 4 trolley wheels to constrain movement of the trolley in certain applications.

Heavy Duty Casters Explained

How To Specify Heavy Duty Casters

 

Heavy Duty CastersThe selection for proper manufacturing of heavy duty casters for your application, although not tough, normally requires a certain amount of practical understanding associated with the application to assure that heavy duty casters will function correctly in addition to providing the longevity within the application.

Time and cash invested within the upfront preparation will ensure that the heavy duty casters, when procured, will provide a lot of years of performance with minimal maintenance repairs. Here are some key points to follow.

First – Total load for all the heavy duty casters in the application – Knowing the total load that the cart being supported by the heavy duty casters, is going to be carrying, is the critical 1st element in your specification. Whenever you clearly calculate the maximum load, increase the total load by 25-30% to make sure a proper safety factor for the application is established.

When you have established that total; after that divide by 3. The rationale for this is no floor is completely level and many occasions the mass is really being supported on 3 of the 4 heavy duty casters. Example: Weight is 2000lbs, times 30% equals 2600lbs. Divide 2600 pounds by three. The total capacity for each of the heavy duty casters really should be 867 pounds. This formulation will not account for shock loading (dumping content on the cart). If you are convinced there will probably be shock loading within your application, use a 300% factor rather than the 30% factor to calculate heavy duty casters load limit.

The reason this is done is to ensure that if a heavy load is dropped into the cart, it will not damage the heavy duty casters. Not to get too scientific, here is an example. If you were to drop a 100 pound weight on to a weighing scale from a height of 12 inches, the maximum instantaneous weight recorded by the scale when the weight is dropped, could exceed 400 pounds recorded by the scale. If the frame and bearings in the heavy duty casters were designed for 100 pound loads, the caster frames could collapse or the bearings could develop flat spots causing the casters to seize up and not roll anymore.

Heavy Duty Casters – Speed and Load

Second – Speed – The next crucial piece of data to assess is the speed at which the heavy duty casters will likely be used. While speed of transport typically has little affect the swivel section, the structure design and material make up of the wheel is crucial to understanding the concerns with speed. Even though speed at which a cart may be rolled is important, the amount of travel time at a certain rate can be even more important. One thing to consider is the moving rate at a specific load. A trolley may possibly travel much quicker any time unloaded rather than when it is full. Generally think about the worse case scenario-fastest speed, in the highest weight for the longest time period. Several manufacturers of heavy duty casters will have testing equipment that reproduce your application in the event you are not sure of your caster selection meeting your specifications.

Third – Floor conditions- Always consider the condition of the floor while deciding on the perfect heavy duty casters for the application. New cement floors with no flaws are very kind to heavy duty casters products. Old floors which have considerable flaws in them (1 deep and 3-4 in diameter) are extremely rough on heavy duty casters and wheels.

Each defect in the floor is a potential hazard to the heavy duty casters and trigger severe damage for the caster wheels, bearings within the wheel, the rotating section or the welds in the caster frame if any. If your floors are uneven, the spring loaded casters may be a better fit for your application.

Fourth – Environment- In what environment is the heavy duty casters application going to take place. Is it going to be indoors at ambient conditions, is it going to outside with greater or lower than ambient heat?

 Is there an opportunity that the heavy duty casters are going to be inside a humid or moist application at normal durations? Be cognizant to temperature from the atmosphere and always contemplate the possibility with the heavy duty casters having ongoing subjection to moisture. Both temperature and humidity will certainly affect the choice of the heavy duty casters.

Fifth – Motor driven vs. manual driven- How the heavy duty casters are going to be moved in their location is extremely critical to consider when choosing the proper heavy duty casters for your application. Manual (people) driven application usually attains speeds of 3 miles per hour along with the forces that the heavy duty casters will experience, it is going to be significantly decreased when manually powered or pulled.

On the other end from the spectrum is a fully powered application. Usually powered equipment will travel more quickly and the heavy duty casters will certainly experience a lot greater force in the day to day operation.

Heavy Duty Casters – Talk To A Sales Engineer First

Be very cautious when browsing data for heavy duty casters as most manufacturers only offer comparisons for manual applications (2-3 MPH). Should you be utilizing catalog specifications to meet a power application you are well on your way to a rapid heavy duty casters malfunction. It is always better to have a conversation with a sales engineer when dealing with powered applications.

It is essential to specify the appropriate heavy duty casters upfront and totally understand the 5 points above when doing so. Skilled application engineers or technical sales people can support you when you tackle a challenging application.

Don't forget the price of  heavy duty casters isn't only the purchase price. It includes related maintenance expenses and down-time. Your costs will sky rocket if you make an incorrect choice of a heavy duty casters not suited for your application.

We consider heavy duty casters often as extremely simple and not requiring much contemplation. Purchasing heavy duty casters from a specification page and on-line price shopping is just a disaster waiting to happen.
