Semi-Trailer Dimensions: Different Types of Trailers for Semi Trucks
This article describes semi-trailers and different types of trailers depending on the semi-trailer dimensions. So what is a trailer? What are the types of trailers for semi-trailers? Semi-trailers are trailers without a front axle. In the United States, the term is also used to refer to a trailer combination, also known as a truck and tractor-trailer. Most of the weight of the semi-trailer is supported by a tractor unit, a removable front axle assembly called a dolly or another trailer tail. Trailers are usually equipped with landing gear (legs that can be lowered) to support them when detached. Many trailers have wheels that are completely removable and can be moved (repositionable) to better distribute the load on the bearing wheel weight factor. Semi-trailers are more common for transportation than full trailers with face and rear axles. Ease of support is listed as one of the best semi-finalists. The two semi-trailers are called tandem trailers or tandem trailers. Another term used is "B train" or "road train" (if there are three or more trailers). The double trailer can be combined with a dolly or a "converter wagon". This is basically one to three additional axles placed under the front of the second semi-trailer. The first semi-trailer is connected to the power unit using the tractor's fifth wheel coupling, and the adapter dolly already connected to the second semi-trailer is connected to the first semi-trailer with a drawbar. Read below for a list of different types of semi-trailers for semi-tracks. Trailer type Flatbed trailer Flatbed trailers are today's most popular and commonly used semi-trailers. It is either 48 feet or 53 feet long and 96 or 102 inches wide. Lowboy. trailer The Lowboy is a semi-trailer that lowers the deck by two. One is just before the gooseneck and the other is just before the wheels. This allows the deck to be very low compared to other trailers. Refrigerated trailer Refrigerated trailers are also known as refrigerated trailers. Usually used to transport refrigerated or frozen products. The temperature inside this trailer can be controlled regardless of the weather outside. Conestoga Trailer The Conestoga Trailer is manufactured by Aero Industries. Build an innovative tarpaulin slide system that covers your valuable cargo without damaging the items below. This protects the termination or transfer of part of the goods or equipment. Step deck trailer Roll deck trailers are very similar to flatbed trailers, except that the maximum horror height must be 10 feet or less. The gradient platform is designed to withstand great features not possible with flatbed trailers. Mainly due to height restrictions. Dry truck trailer The dry track is a closed trailer. Dry truck trailers are the most common shipping container. These trailers are completely sealed. Therefore, charging is protected from external influences. Multicar trailer Multicar trailers are utilized to transport vehicles and trucks. They can carry 2-8 vehicles. If you need to tow multiple vehicles, use a double-decker trailer. Due to the height of the bridge, height cannot exceed 11.6 feet.

How To Create A Secure IoT Network To Guard Your Connected Devices
IoT has created a bridge between the physical world and the Virtual World. With all conviction, we can expect IoT as an indispensable part of our lives. But as the IoT implementations are growing, the security concerns are also growing at the same pace. And Today, being a leading IoT service provider, we are going to share how you can create a secure IoT network that will keep your connected devices as safe as possible. Steps To Create a Secure IoT Network Let me tell you very straight that securing the IoT network doesn’t require a completely new or complex set of ideas and principles. The core lies in the best practices while designing the IoT solution.  As there are many small to big things considerably, We can say IoT security is a multi-faceted effort that requires big moves as well as small adjustments to ensure networks, data, systems, and devices are protected.  What is Security By Design? Security by design is a practice that ensures security as a crucial consideration at all stages of product creation and deployment. Often in the IoT developments led by speed and other priority factors, the security considerations are included late in the design and prototyping phase. That results in security breaches. It’s important to remember that as devices and their firmware get obsolete and error-prone in time, they may become an attractive target of bad cyber actors. Hence, it’s crucial to manage the lifecycle of security devices and cloud spectrum to reduce the attack surface. The sad part is that most of the time, robust and long-term security strategies are overlooked during IoT implementations. Security is not a one-time activity, rather an evolving part of the IoT ecosystem that should support IoT deployments’ lifecycle in: Adding new devices and decommissioning others, Onboarding to new cloud platforms, Running secure software updates, Implementing regulated key renewals, Maintaining large fleets of devices. All these activities require comprehensive management of identities, keys, and tokens. To avoid time-consuming and expensive services in the field, IoT Security lifecycle management solutions must facilitate updates remotely while executing them across large scale device fleets. Now let’s see the Security concerns in two popular forms of IoT: Tips To Secure Consumer IoT Devices Smart speakers, domestic appliances, connected toys, and smart locks are all potentially vulnerable if not properly secured by design and during their expected lifespan.  For example, someone who owns a Google Nest Hub and other Xiaomi Mijia cameras around his home claimed that he received images from other people’s homes, randomly, when he streamed content from his camera to a Google Nest Hub. There are many such examples where the design loopholes have caused many consumers more harm than good. The good news is that ETSI recently announced ETSI TS 103 645, the first worldwide standard for consumer IoT security. This sets a benchmark for how to secure consumer products connected to the internet and aims to promote best practice. Additionally, here we are going to share tips that will help you in designing a secure IoT network for your consumers and smart homes. Know Your Network and The Connected Devices – When we put together several devices over the internet that potentially leaves your entire network vulnerable. It’s common to lose track with an increasing number of equipped devices. Hence it’s essential to know your network — the devices on it and the type of information they’re susceptible to disclosing.  Assess the IoT Devices on Your Network First, know which devices are connected to your network, audit your devices to understand their security posture. While selecting devices check for newer models with stronger security features, etc. Further, before making a purchase, read up to understand how much of a priority, security is, for that brand. Input Strong Passwords to Protect Your Devices and Accounts Use strong and unique passwords that will assist you in securing all your accounts and devices. Get rid off the common passwords like “admin” or “password123.” Make use of a password manager, if needed, to keep track of all your passwords. At the same time ensure that you and your employees don’t use the same passwords across multiple accounts and be sure to change them periodically. Choose a Separate Network for Your Smart Devices Separating networks is a smart way to protect your smart devices in the IoT network. With network segmentation, even if attackers discover a way into your smart devices, they can’t access your business data or sniff on that bank transfer you did from your personal laptop. Reconfigure Your Default Device Settings Usually when we receive our smart devices they are packed with default insecure settings. And things become worse if we do not modify their configurations. As weak default credentials, intrusive features, ports and permissions need to be assessed and reconfigured as per your requirements. Install Firewalls and Other IoT Security Solutions to Identify Vulnerabilities To safeguard your Smart homes and other consumer IoT networks block unauthorized traffic over the wire through firewalls. At the same time run intrusion detection systems/intrusion prevention systems (IDS/IPS) to monitor and analyze network traffic. This is where you can use an automated scanner to uncover security weaknesses within your network infrastructure. Use a scanner to identify open ports and review the network services that are running. Now let’s check out the key steps to protect your enterprise network against modern security threats. Steps To Protect Your Enterprise IoT Network We have seen many manufacturing industries adopting IoT and growing. However many aren’t serious enterprise security, that’s a mistake. Because we have seen that In 2018,  21% of companies reported a data breach or cyberattack due to insecure IoT devices. So do not let that happened with you and follow the steps below to protect your enterprise IoT network: Step 1:  Be alert of the risk As IoT is relatively new as compared to IT, hence some of the threats are newer and not as widely used, and make companies reluctant. But we forget that IoT security is like buying insurance. We think we won’t ever have to use it, but the odds are, we might. So it’s better to realize that with a lot of connected devices in use, we might have vulnerabilities that need to be minimized and fixed. Step 2: Design a Secure network architecture The Ponemon study found that less than 10% of organizations are confident they know about all of the printers, cameras, and building automation systems on their networks that are connected to the Internet. Hence, it’s essential to carefully design your network architecture. And protect your devices from the network, and further protect your network from the devices. Step 3: Observe Your Suppliers and Vendors Attackers are smart today, they may target you through the suppliers and vendors. So do not underestimate the vulnerability that comes along with companies you connect with.  It’s a better practice to include the security practices as part of your vendor risk management process. Step 4: Practice For the Data Breach You must prepare for an IoT data breach the same way you prepare for disasters like fire, earthquake, or other. Make a plan, have a regular drill, and keep the plan updated. It’s good to have regular exercises to test your data-breach preparedness.  How will you tackle the situation If you get breached? you should have a well-documented plan for the same. Step 5:  Control what you can, and learn to live with calculated risk It is important to realize that while you should do everything that you can do, you can’t expect to prevent everything. So learn to live with a calculated risk. For something that’s as crucial as a backdoor into your entire network, which is really what a smart-building management company represents, you really need to keep a close eye on their security practices. Step 6: Start now, and get ready for whatever comes next IoT being an emerging technology can not and should not be removed from our enterprises.Although there is risk that comes with it but like all excellent growth you need to take that risk and better prepare yourself to reduce the chances of mishappening like data breaches and others. You know new devices are coming with each passing days, hackers are becoming more creative, and the risks are getting more profound and devastating. So, Be aware and take proactive steps to secure your IoT network. And if you are looking for any other assistance in IoT services, do not forget to check our IoT services page.
Horizontal vs vertical marketplace: which idea is better?
The article was initially published in Codica blog. Nowadays, the concept of the marketplace is commonly known. Various success stories of AliExpress, Amazon, Etsy and other marketplaces inspire startuppers to build their own e-commerce platform. This article will help you to find out what marketplace type suits you the best - vertical vs horizontal, and how they differ. Online marketplaces gain momentum Marketplaces are online platforms for selling and buying services or products. These platforms support interaction between shoppers and vendors. Using marketplaces, consumers can quickly find the necessary product or service and compare prices. In turn, vendors save on driving traffic to their trading platform. The online marketplace owner gets a profit from the web solution through different revenue strategies, including their combinations. But to define the revenue model that will bring you money, you should choose a marketplace type. Except for general B2B, B2C, and C2C classification, marketplaces are divided into two main types: horizontal and vertical. Let’s consider them to decide which one is better. Horizontal marketplace The horizontal marketplace is a model that allows consumers to buy everything they need in the same place. Pros of horizontal marketplaces The horizontal marketplace has such perks: - Large market share It is the most evident advantage of the horizontal model. These marketplaces can attract more merchants from multiple industries. - Wide customer base The horizontal marketplace is attractive to a wide audience with a big range of products under a single name. A huge number of customers leads to raising profit. - Smaller risk of demand shortage Products and services in a horizontal platform are manifold. Indeed, it affects user involvement. Thus, there is a smaller risk of the lack of demand in the marketplace. However, a horizontal model has its cons. When you offer a wide range of products on the platform, your marketplace can’t dominate in a certain industry. Example of the horizontal marketplace Amazon is a wonderful example of a horizontal platform. It offers nearly all, from books to web cloud services. This platform is very money-making. Here is a diagram that shows Amazon’s annual revenue from 2006 to 2021. Source: Statista.com Vertical marketplace The vertical marketplace focuses on offering the best services in one certain category. It is easier for the vertical model due to the target group limitation. Pros of vertical marketplaces This vertical marketplace model has the following pros: - Possibility to focus on one certain industry This business model means your marketplace competes for a specific market segment. Therefore, you can dominate in your domain. - More personalized approach Surely, it is easier to provide a limited number of customers with a personalized experience than a mixed and vast audience. - Quicker sales A decreased competition can lead to faster sales on the website. Still, despite all its pluses, the vertical model has its flaws: a platform created vertically has no impact on other domains. Example of the vertical marketplace For example, such a lucrative handicraft platform as Etsy is a vertical platform. Etsy is a two-sided e-commerce marketplace that aims to trade handmade or vintage items from individuals. Currently, this website has more than 5 million users and over 60 million goods. It is worth emphasizing that it is the vertical model that has brought Etsy such success. Which marketplace type is a winner? Let's consider the main differences between horizontal and vertical marketplace models. - Horizontal marketplaces have much more services or products in range than vertical ones. - Horizontal marketplaces help businesses enter to market to a large audience. Vertical marketplaces are focused on a specific user category that is found in the vertical website. - Vertical marketplaces offer narrowly specialized products and services. In turn, horizontal platforms offer plenty of services and goods. But the question is, which model is better? In short, both vertical and horizontal marketplaces are effective when implemented correctly. Conclusion There is no clear answer to whether a horizontal or vertical marketplace is better for your future web solution. The choice depends on your requirements and possibilities. If you have sufficient knowledge of a certain market segment and are sure of your idea's profitability, build your marketplace vertically. If you want to cover a larger audience and know how to beat the competition, choose the horizontal model.
