Heavy-duty casters are designed to hold heavier loads than light-duty casters. They can also last longer with proper maintenance.
Regular inspections can identify issues like crooked components, erratic movement, or noise during rolling that could indicate loose or damaged parts. Addressing these issues promptly can save businesses from costly repairs, floor damage, and even employee injury that a simple maintenance routine could have prevented.
Inspecting the Wheels
Simple preventative maintenance can significantly increase how long a wheel or caster lasts. In addition to lubrication, inspecting the wheels for flat spots and embedded material (including screws, metal chips, and sharp objects) is vital. Using thread guards may also help to delay the buildup of hair, dirt, debris, and other materials, lowering the frequency of necessary cleanings.
It is also essential to ensure that a caster is not positioned or anchored so that it has too much pressure on one spot. This can cause the caster to fail prematurely. Inspecting the caster frame and ensuring that it is not bent is also essential for the longevity of the caster.
Flipping over any equipment with a caster at least once a month is essential to check the hardware fittings that hold the caster in place. These are the vital pieces that work against gravity daily in all environments and are prone to wear, damage, or falling off without routine inspection and maintenance.
Inspecting the Fasteners
When casters are not adequately maintained, the hardware fittings connecting them to equipment can suffer corrosion and wear. This can lead to the casters failing or the wheels and bearings becoming damaged. Ideally, casters should be inspected every month and lubricated every month to extend the life of these components.
Loose hardware fittings can also cause vibration and shifts in the load, making it difficult for workers to move carts or equipment. The vibrations can also damage the floor, leading to costly repairs.
In addition to visual inspections, eddy current, and ultrasonic testing can help to spot hidden flaws in fasteners, which are difficult to detect visually. Dimensional inspections ensure that nuts and bolts have the stated dimensions. This can save companies money on repairs by preventing unnecessary replacements. This is especially critical for industries that rely on mission-critical fasteners, such as aerospace and aircraft production.
Inspecting the Floor
Unlike regular casters, heavy-duty casters can hold much heavier loads and are made to be used in rough environments. However, they can be damaged if not properly maintained. This is why it is vital to follow the steps in this article so that they can last for as long as possible.
The primary purpose of these casters is to make it easier for people to move items around. They are ideal for various applications in factories and other industrial units, including furniture manufacturing, warehouses, and distribution centers.
They are also helpful for waste removal operations that collect and move community garbage to garbage trucks or other disposal points. Lastly, they are often used on medical equipment, such as carts that contain X-ray machines, USG equipment, and MRI equipment. These can be heavy and require much force to move. This is where these casters come in handy, making it easy for one person to move the carts around.
Inspecting the Brakes
The caster wheels used on heavy equipment often get dirty and cause erratic rolling. This is because phenolic, steel and other hard wheel materials collect staples, metal particles, and other floor debris that embed into the wheel tread. Use thread guards to reduce this occurrence, and ensure the casters are correctly rated for your equipment’s load.
If a caster is under-rated for the equipment it moves, you risk the caster failing or your equipment colliding with workers who are pushing it. Also, if the casters are not properly lubricated, you’ll have to put in more effort and time when moving your equipment.
In addition to ensuring that casters and hardware fittings are secure, visually inspect the air brakes for signs of wear and tear. Look for brake chamber brackets that are cracked or bent. Also, check the camshafts and cam faces for pitting, scoring, ridges, or cracks. The clevis pin bushings should also be free of cracks and other damage.
