What is a Tow Truck?
4 Answers
Tow truck, fully named as road tow truck. Purpose of tow trucks: A tow truck refers to a specialized vehicle equipped with road rescue operation equipment. Since breakdowns and accidents are inevitable when vehicles are traveling on roads, especially on highways, such incidents often occur. The task of a tow truck is to promptly remove the broken-down or accident vehicle from the scene, ensuring smooth traffic flow. Therefore, road tow trucks are also known as road rescue vehicles. With the increase in high-grade roads and the number of vehicles in use, tow trucks have also developed. Classification of tow trucks: Tow trucks are generally categorized into four main series based on their structural types: separable lift-and-tow tow trucks, integrated lift-and-tow tow trucks, flatbed tow trucks, and conventional tow trucks.
I've seen way too many tow trucks, the kind specifically designed to clear stalled vehicles off the road. Back when there were traffic jams on the highway, I watched as they hauled away accident vehicles. They come with either a retractable tow arm or a flatbed under the chassis, capable of lifting small cars directly. These things even come in different types—flatbeds just load the car up and tow it away, while wrecker-style ones use steel cables to secure the front wheels and drag them along. Municipal services and traffic police use them the most; any car broken down in the middle of the road relies on them to clear the scene. Their engines and frames are reinforced, otherwise they wouldn't be able to pull such heavy disabled vehicles. They have to work even in rainy weather, so tow trucks are built extra tough and durable, and they drive pretty steadily too.
Anyone involved in road rescue knows that a tow truck is an indispensable tool. It's like a mobile repair station, capable of directly transporting broken-down or wrecked vehicles to repair shops. The lifting platform on the truck is particularly crucial—hydraulic arms are used to lift sedans, while off-road vehicles are slowly pulled onto the flatbed. The newer models even come with automatic wheel-locking devices and anti-slip pads, making towing safer. Every rescue team I've worked with keeps these professional tools on each vehicle. Driving a tow truck is much more challenging than driving a regular truck—you need to know how to operate the mechanical arm and properly secure the load, or an emergency brake could send the towed vehicle flying.
Last week my car broke down on the Third Ring Road auxiliary lane, so I called a tow truck. That blue-and-yellow vehicle was particularly eye-catching. The driver got out and pulled out a bunch of tools. There was a large steel plate at the rear that could be lowered as a ramp, and he guided me to drive my front wheels onto it to get locked in. During the ride, I learned that they have two types - daily rescue models and heavy-duty rescue models. The tow trucks for regular cars weigh about four to five tons, but for big rigs they need to call in the twenty to thirty-ton ones. The control panel is behind the cab, with levers to adjust the ramp's lifting angle. The rescue station staff said these trucks require regular maintenance of the hydraulic lifting system, otherwise getting stuck mid-operation would cause even bigger troubles. It cost me 200 yuan to get towed to the repair shop, and I felt it was money well spent.
