If you’ve spent any time driving a lorry, you’ll know that the feel of the vehicle is different to that of conventional vehicles. It’s not just about wheelbase, engine size and vehicle weight, however: parts of the mechanism are actually qualitatively different from those of more common road vehicles. One of the key distinctions between your average vehicle and those specifically designed for haulage work is in the brakes. The brakes used in HGVs are known as compression brakes, while those used elsewhere tend to be hydraulic brakes.What Are the Similarities?Compression and hydraulic brakes have a number of similarities. Most notable is, of course, the end result: both of them are designed to reduce the velocity of a vehicle in motion. When you look at the "business end" of either system (i.e. the part closest to the wheels), both the brakes used in haulage work and those used in conventional vehicles have similar mechanisms - drums, shoes and pads are all present and perform the same functions.
There are some similarities at the front-end too: both kinds of brakes are similar from a driver’s perspective, operating a lever in order to ultimately apply friction to the wheels and hinder their rotation. However, the two systems have a number of key differences.What Are the Differences?From an external, "black box" perspective, the differences you’ll notice are the slower response time of compression brakes to hydraulic brakes: as a driver, when you hit a hydraulic brake, you’ll feel the effect on the car instantaneously. However, as any haulage worker will confirm, hitting the brakes on an HGV takes a little under a second to even begin to slow the vehicle. Additionally, compression brakes tend to make a loud sound of escaping air when used.The two mechanisms are also very different.
Hydraulic brakes transmit the motion of the lever through a hydraulic system. As the motion is transmitted through incompressible fluid (brake fluid), these brakes are very responsive. Compression brakes, however, use compressed air: essentially, during the compression stroke of the engine’s pistons, air is allowed into the cylinders and is compressed by the downstroke. This compressed air is used to turn the camshaft and ultimately apply friction to the wheels, through either a power screw or an S-cam and a drum.The lack of brake fluid means that there is no fluid to replace in compression brakes, and the kind of brakes that use a power screw (air disc brakes) are almost as responsive as hydraulic brakes, reducing stopping distance by 40% when compared to drum brakes. However, due to traditional dominance of drum brakes in the industry, some countries have been slower to adopt disc brakes for haulage work than others. In Europe, for example, the vast majority of lorries operate on disc brakes, while in North America only about one in twenty trucks runs on disc brakes.If your lorry is still running on drum brakes, you might want to consider upgrading: the shorter stopping distance is well worth having. In any case, improvements are being made all the time, and there’s no way of knowing how long it’ll be before a new braking system comes along.Norman Dulwich is a Correspondent for Haulage Exchange, the leading online trade network for the road transport industry.

A home business is still a business
2018年12月21日Having a home business is not as easy as others claim. Some people think that home business owners are living the life. They think that since they can control their own time, they are able to work at any time they wish to and relax when they want to. But they are wrong. Home business owners do not only lie on their backs and do work when they want to. They also have deadlines and goals. They also need to work if they want to improve their business. Here are the four things that help home business owners succeed. Focus It is very hard to have a home business if you do not know how to keep your focus. Unlike the office which has a boss looking over your shoulders every minute, the house has lots of distractions.
There is the television and there is the video game console. There is also your dog you constantly licks your foot along with your family members who always call you for something they need to do. It is not easy to focus when you have a lot of things going on. This is the reason why you should have extreme focus if you want your home business to succeed. Consistency Along with focus, you also need to be consistent. This means that if you are going to work on your home business for a set number of hours of day, then you need to do it. The harder part is usually showing up to do the work. But if you can control yourself and ignore the distractions then you can be consistent about it and help your home business succeed. Determination Another thing that will ensure your home business success is determination. A lot of people usually lose the fire when they are working on the same thing every day. Determination is the only thing that people can depend on in these times. It can help them feel empowered to meet their goal and not give up. Not Giving Up In connection to the last factor, a lot of people usually give up before they succeed. I put this as a separate factor from determination because the act of not quitting is different from determination.
Determination is where a person will stop at nothing to reach his or her goals while the process of not giving up is where a person simply moves forward. Once you run a home business, you will find that there are downtimes when you do not want to move. Instead of giving up, step back. Take a rest and resume your work later. These are just some of the characteristics that you need to have if you want to succeed with a home business. A home business is still a business. It still requires dedication and discipline to prosper. It is not something that you set up and leave. It needs some time and effort in order to bear fruit. With this, you must nurture it. In the end, the success of your business is up to you.
