Hoisting Mechanism And Spare Parts
The hoisting mechanism for a Tower Crane typically consists of a combination of a motor, a gearbox, wire ropes, and a hook block. Here is a breakdown of its components and how they work together:

These manufacturers have their own production catalog, and its external identification model code is: Liberation CA Dongfeng EQ DFL DFAC Jianghuai HFC Beifutian BJ Northern Mercedes ND China National Heavy Duty Truck ZZ Shaanxi Heavy Duty Truck SX Chongqing Hongyan CQ Chongqing Iron Horse XC An Huai Hualing HN Jiangling JX Isuzu (Qingling) QL and so on.
The production bases and distributions of the above manufacturers are as follows: Liberation has Changchun, Qingdao, Chongqing, and Liuzhou. The main identification method is as follows: Example: The last letter of CA1170P7K2L11T4E is to identify the home base of its product. If the latter letter is A80, it will be the liberation Qingdao base, and A95 will be Liuzhou Special Steam.
Most of Dongfeng's products belong to the EQ series, including Dongfeng of Xinjiang, Dongfeng of Hubei, Dongfeng of Shenzhen, Dongfeng of Hangzhou (Dongfeng Nissan ( DN ) and Dongfeng DH ) and Dongfeng of LIU | (In the use of EQ catalog, it also obtained its own independent production catalogue for LZ. ), Yunnan Dongfeng. Hubei Dongfeng is divided into: EQ series DFL series (Tianlong Tianjin) DFAC series (Dongfeng light truck below 180 horsepower)
In addition to the above two large state-owned enterprises, other manufacturers are basically localized production, and their serial letters are very characteristic of geographical attributes.
Here I mainly explain the problem of “Steyrâ€: Most of the people in our automotive industry are often confused by Steyr in Shaanxi and Steyr in Shandong (China National Heavy Dumb), although they belong to different manufacturers but all Heavy trucks belong to the same class. I think this is the main reason to get everyone confused. In fact, as long as everyone understands the origins of Steyr, it will be very clear: “Steyr†was first appeared in Shaanxi as a heavy-duty automobile production line introduced by China to fill the domestic maladjustment, when the country was in Shaanxi. Established China Heavy-duty Truck Group Co., Ltd., and launched a full range of "Steyr" production lines for light, medium-sized, passenger, and heavy-duty vehicles. However, due to various reasons, Shaanxi-based "Steyr" only used heavy-duty vehicles and special-vehicle production lines. Leave other production equipment idle. In order to adapt to the development of the market, China Heavy-duty Truck Group Co., Ltd. obtained a naming rights for Shandong Heavy-duty Truck Group Co., Ltd. and obtained a set of production drawings and some equipment. Chongqing Hongyan received some technical support and production equipment. Chongqing later in the production process. The "Steyr" name is no longer used. The majority of the "Steyr" production platforms also belong to Shaanxi Zhongqi. After the separation, Shandong Heavy Duty Truck mainly focused on the development of autonomy of heavy vehicles. Since the joint venture with Hong Kong, Shandong Heavy Duty Truck Co., Ltd. has also developed the "Steyr" brand, such as: HOWO Haoyun Yellow Marshal Gold Prince and other series. (We often see in the car announcement Starsky - Steyr which has the existence of a gold prince such as: ZZ3251M3841C main identification method is: the fourth digit behind the letter is " 1 " if it is " 3 " represents "Tel" " 4 " on behalf of the Yellow River Marshal " 5 " represents Haoyun " 7 " on behalf of Hao Hao).
The meaning of the liberation chassis model: CA5253GJYP7K2L11T3E where P7 represents the high-top two-bedroom cab (if the PK2 represents a narrow-body cab) L11 represents 9.5 boxes of long T3 on behalf of the bridge E on behalf of Euro III emission standards.
1. Motor: The hoisting motor provides the power needed to lift and lower loads. It is usually an electric motor that generates high torque to handle heavy loads.
2. Gearbox: The motor's rotational motion is transmitted to the hoisting drum through a gearbox. The gearbox helps increase the torque and reduce the speed of the motor, enabling the crane to lift heavy loads at a controlled speed.
3. Hoisting Drum: The hoisting drum is a cylindrical drum around which the wire ropes are wound. It is directly connected to the gearbox and rotates as the motor operates. The drum's size and design determine the amount of Wire Rope it can hold.
4. Wire Ropes:
The wire ropes are wound around the hoisting drum and connected to the hook block. These ropes are made of high-strength steel and have a high load-bearing capacity. Multiple wire ropes are used to distribute the load evenly and ensure stability during lifting operations.
5. Hook Block: The hook block is attached to the lower end of the wire ropes and is responsible for carrying the load. It consists of a pulley system with one or more sheaves, which allows the wire ropes to change direction and support the load securely.
During operation, the motor drives the hoisting drum through the gearbox. As the drum rotates, the wire ropes are wound or unwound, depending on the direction of rotation. This movement raises or lowers the hook block, allowing the crane to lift or lower loads.
The hoisting mechanism is controlled by the crane operator using various controls and switches. Safety features such as limit switches and overload protection systems are also incorporated to prevent accidents and ensure safe lifting operations.
China's current commercial vehicles are divided into three categories: one for light vehicles, two for medium-sized vehicles, and three for heavy vehicles. In these three categories, there are seven sub-categories. In China, these three types of relatively complete manufacturers are: Liberation Dongfeng Jianghuai Beiqi Foton Heavy-duty Truck Manufacturers: Heavy Truck Shaanxi Automobile Red Rock Iron Horse Hualing Northern Benz Common Light Truck Chassis Manufacturers: Jiangling Isuzu Subdivision of Seven Small Classes Let's take ZZ1311N4711 as an example: The first “ 1 †after the letter represents the general truck series. If “ 2 â€, it represents the full-drive series. If " 3 " represents the dump truck series, " 4 " represents the tractor series, " 5 " represents the tank truck series, and " 6 " is the passenger train series " 9 " represents the semi-trailer series. Under normal circumstances " 1 " and " 5 " can be used universally, while the " 2 " full-drive models also include: general trucks, dump trucks, tractors (gun cars, guided missile trucks) tank cars (rarely seen) Passenger cars these five small categories.
