A mobile lifting crane is a critical piece of equipment for many construction and industrial projects due to its ability to safely and efficiently lift and move heavy loads.
If you want to rent a crane to complete a project, you need to understand the different machine parts, including what they do, how they work together, and why they are so important to complete intensive tasks efficiently. Read on to find out more.
1. Boom
The boom refers to the long arm that extends from the body of the crane. This part of the crane moves and supports heavy materials and objects, usually suspended midair. You can adjust the boom to reach different heights, depending on the task at hand.
The boom is able to perform these tasks thanks to the powerful hydraulic system, stabilizers, and pulleys along the arm's length. The boom's hydraulic system consists of a series of cylinders that connect to the boom and allow this component to bend, stretch, and move as needed.
The hydraulic fluid in the system drives and controls the cylinders to transfer power. This system also includes a control valve that allows the operator to adjust the pressure and flow of the hydraulic fluid, which allows the operator to customize the boom's movement.
Additionally, safety features are built into the hydraulic system, such as pressure relief valves, that prevent the boom from an overload.
If the force exerted on the boom exceeds the maximum amount of pressure the system can handle, the pressure relief valve will open to release the pressure and prevent damage. This mechanism helps maintain the crane's stability and keeps the operator and the surrounding environment safe.
2. Counterweight
The counterweight helps offset the weight of whatever object the boom arm lifts, which enables the arm to remain stable while in motion. The counterweight section is usually behind the cab and away from the boom.
The crane's counterweight system consists of several heavy blocks that sit at one end of the machine. The system works to create a balance with the weight of the object at the other end of the boom arm. This workaround helps with even weight distribution throughout the crane. This way, the crane won't tip over when you lift a load.
3. Outriggers
Outriggers are important parts of a crane that help provide stability while the crane is in operation, especially on uneven terrain. Uneven terrain poses a huge challenge because the crane needs to remain stable when you begin to lift a heavy object. The outriggers extend away from the crane's base and help spread out the crane's weight as extensions create a stable base.
The outriggers feature an adjustable leg that you can extend and retract. You can easily extend the legs to increase stability or retract them when the machine is in motion. The outriggers also rely on hydraulic cylinders and feature locking pins to keep the crane in place, no matter the terrain.
Some cranes also feature outrigger pads, which are the rubber or metal blocks you place beneath the outriggers to further increase stability. These pads provide a larger ground surface area and provide a firmer grip between the machine and the ground.
Always extend these outriggers before you operate the crane. Take a few moments to confirm that the outriggers have properly extended and locked into place before you start any work.
Before you select a mobile lifting crane for your project, make sure that all these components are present and in proper functional condition. You'll save yourself money (and headaches!) and also ensure that every job site runs safely every single time without fail.
