What Are Some of the Most Common Hoist Problems Encountered in Overhead Cranes?


Your hoist is the most important part of keeping your overhead crane in tip-top working order. But in order to keep it that way you always need to be on the lookout for the following issues: Abrasion Abrasion is an extremely common issue with the hoists on overhead cranes mainly because it is a very subtle process. It is often the result of poor lubrication which causes vulnerable areas of your hoist, such as chains, wire, joints and any other moving parts to be damaged. The best way to spot abrasion is to look for shiny surfaces that indicate two surfaces rubbing together. Looking for t


Why is Motor and Gearbox Alignment Critical?


Early detection of motor and gearbox alignment issues allows problems to be corrected before a component fails. A misaligned electric motor or gearbox can easily damage other connected parts, increasing the time and expense involved in repairs. These failures can create safety hazards and cause unproductive downtime which can be easily prevented. If left unrepaired, alignment problems could give rise to a “cascade failure” where spiking repair costs approach the cost of new equipment, thus “totaling” your valuable equipment. Why Use Infrared Thermographic Studies for Motor and


Why Should You Get a Line and Load Check?


A line and load check is an important part of any electric motor preventative or predictive maintenance program. The first thing you need to understand is what the words “line” and “load” mean to individuals working in the electrical trades. The “line” generally refers to the wires that bring power (electricity) from the source to a device. Some people also refer to the “line” as “incoming” or “upstream” as well. The “load” refers to wires that carry power to other devices along the circuit. These are also known as “outgoing” or “downstream” wires. Bo


What Types of Problems Can Be Detected Using Ultrasonic Motor Testing?


Ultrasonic motor testing (AKA - motor vibration analysis) is an excellent “nondestructive” means of finding possible problems with the operation of your electric motor before it becomes a serious problem. What is a nondestructive testing? It is a group of testing methods that evaluate the properties of a particular object without causing any damage. A lot of nondestructive tests can be performed while the unit is still in operation. What Problems Can Motor Vibration Analysis Detect? Ultrasonic testing uses a lightweight ultrasonic translator to listen for possible problems in the


5 Factors to Consider Before Buying a New Industrial Electric Motor


Buying a new industrial electric motor is a huge investment, and it is important to do your homework before putting money down on one. Here are some factors you should think about before making a purchase: 1  Age of the Motor You Want to Replace The age of the motor is very important in these decisions. Motors manufactured before 2005 are far less efficient than those manufactured after that time. New standards established by the Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007 mandated that electric motors be more energy-efficient, which will save you


What is an Ingress Protection Rating for Electric Motors?


An Ingress Protection rating is a code that classifies and rates the degree of protection provided by an electric motor casing or enclosure against outside contaminants or “intrusion” that is published by the International Electrotechnical Commission.   The IP code is a two or three-digit code that identifies the level of solid particle protection, liquid ingress protection and also any special circumstances about the motor such as oil resistance, weatherproof, etc. This is important information to know if you are getting an industrial motor repair or purchasing a new electric m


What Factors Should You Think About Before Buying a New Industrial Pump?


Buying a new industrial pump is a huge investment, and it is important to do your homework before putting money down on a new pump. Here are some factors you should think about before making a purchase: Flow Rate This determines how fast a pump can pump a specific amount of liquid (gallon or liter) per minute. This is the most basic measurement of the effectiveness of the pump. Inlet Size The inlet size determines how fast a liquid can be sucked in and displaced. The bigger the inlet, the faster liquid can be processed through the pump. Composition of the Liquid to be Pumped Most ind


4 Little-Known Factors That Impact the Quality of Your Electric Motor Rewind


A superior electric motor rewinding service can make your existing motor run as good as–and sometimes even better than–new. But superior results depend on several factors that you might not have considered when seeking out an electric motor rewinding shop. Here are some of the things you should think about when selecting a service provider. Where the Motor Rewind is Performed An electric motor rewind is a delicate process, and removing the dirt, old insulation and grime accumulated after years of use within a motor is a difficult dirty practice (in most cases). These particles can co


4 Factors to Consider When Selecting Electric Motor Bearings


Motor bearings are a critical component of any electric motor, designed to consistently transfer loads from the shaft to the motor and support the rotor. The failure of these bearings typically result in expensive electric motor repairs. Here are some factors you should consider when selecting the best electric motor bearings: Speed The speed of the shaft directly impacts decisions you need to make about selecting the right kind of electric motor bearing. Some of the factors that need to be considered include: Lubricant used Size of the bearing Insulated or uninsulated? Cag
