Lever arms are commonly used to control machines. Also known as lever handles, they support a variety of machine-related applications. You can use them to start and stop machines, change the gears, make adjustments and more. If you’re going to use a lever arm, though, you’ll need to choose the right type.
#1) Straight vs Offset
Some lever arms are straight, whereas others are offset. Straight lever arms feature a straight handle. Offset lever arms feature a crooked or “offset” handle. You may want to use an offset lever arm in small spaces. With their offset handle, you can easily turn them in small spaces.
#2) Number of Handles
You should consider the number of handles when choosing a lever arm. Not all lever arms have a single handle. Some of them have multiple handles. There are lever arms available with two handles, and there are lever arms available with four arms. Multi-handle lever arms such as these are ideal for applications that require more torque. You can grip and turn two of the handles to generate more torque for intensive applications.
#3) Chemical Resistance
Lever arms are almost always used with machines. Machines, of course, are oftentimes exposed to chemicals. Therefore, you should consider chemical resistance when choosing a lever arm. Fortunately, many lever arms are resistant to chemicals. They can withstand oil, grease, solvents and other chemicals without degrading.
#4) Material
Different lever arms are made of different materials. One of the most popular materials in which lever arms are made is steel. In addition to steel, you can find lever arms in cast iron. Cast iron is heavier than steel, but it’s more susceptible to corrosion. Other lever arms are made of glass-reinforced technopolymer.
#5) Support for Angle Limit Stop Pin
Depending on the application for which you intend to use it, you may want to choose a lever arm that supports an angle limit stop. An angle limit stop pin is a pin that limits the degree to which you can turn a lever arm. With an angle limit stop pin, you’ll only be able to turn the lever arm in a limited degree of rotation.
#6) Removeable Cap
Some lever arms have a removable cap. Removable caps are used to cover the handle or handles. If you discover that the lever arm is dirty, you can pull off the removable caps to thoroughly clean it.
