Understanding Dynamic Braking Systems Explained for Mobile Cranes

Hoists used on cranes can lead to serious injuries. Whether you are moving loads vertically or horizontally, you need brakes to control the movement of the hoist mechanisms and ensure that you are always in control of the crane and the load. A crane without the right set of brakes is a ticking time bomb, ready to cause problems at any time. Thankfully, there are dynamic braking systems for those who have a keen eye on safety in the world of cranes. Here is a discussion that will give you more insight on dynamic braking systems for mobile cranes:

How Does Dynamic Braking Work?

Dynamic brakes for a mobile crane come with special devices called inverters or variable frequency drives. These inverters interplay with the magnets and alternating current (motors) to initiate a braking effect on the hoist mechanism of the crane.

What are the Benefits of Dynamic Brakes for Mobile Cranes?

Dynamic braking systems have a host of advantages over other types of brakes in the world of cranes. Here are some of the most significant ones:

Lower power consumption: low power usage is one of the things that gives dynamics braking system an edge over other braking systems in the market. The variable frequency drives are used to draw a generator effect that resists the action of the motor. As the drive regulates the motion of the load, the opposing force creates electrical energy that flows back to the inverter in the form of alternating current.

The alternating current changes into direct current, moves into a direct current bus and reaches a level where it is dissipated as heat. The dissipation occurs through an electrical switch and brake choppers and moves on to the braking resistors. In this way, a dynamic braking system doesn't have to draw power from the source all the time.

Prevent Over-speeding: dynamic braking systems are effective at the primary function that you need them for, enhancing safety when working with a mobile crane. Dynamic braking systems have braking resistors that detect and stop the uncontrolled downward motion of the hoisting mechanism. This prevents the downward pull of the load on the hoist, which can make the hoist to move faster than the speed required by the motor. With these brakes, the operator is always in control.

Gradual Wear on Brake Pads: Mechanical brakes on mobile cranes wear down rapidly because of intense friction. This is not the case with a dynamic braking because the reliance on motors reduces the need for severe contact between braking parts.

About Me

Industrial Supplies and Other Stuff

Hello, my name is Damian and on this blog, I will be discussing a topic which perhaps doesn't seem that sexy. The topic is industrial supplies and other stuff like equipment procurement. You are probably wondering how an 18-year-old got so interested in this subject. A lot of other people think I am strange and that I should be out chasing girls or something. Well, I got into this subject when I had to complete a college project on a local business. I ended up spending an entire summer hanging out at the local industrial plant. I learnt so much about the industry that I decided to start this blog. I hope you like it.
