Truck with crane Full-load truck The truck is a kind of equipment for lifting, revolving and hoisting of goods through hydraulic lifting and telescopic systems. It is usually installed on trucks.


The classification Cheng Li with the car crane is divided into brands according to the brand : Dongfeng, Jiefang, Futian, Jiangling, Jianghuai, Liuqi, etc. According to the tonnage, the Cheng Li truck mounted crane is divided into: 3.2 tons, 4 tons, 5 tons, 6 tons, 7 tons, 8 tons, 9 tons, 10 tons, 12 tons, 16 tons, 20 tons of truck-mounted cranes divided into: 2 Arms or 3 arms, 4 arms, or multiple arms. Cheng Li’s truck crane is divided into two types according to the crane : a straight arm type and a folding arm type crane.


The composition, use and characteristics of Cheng Li's truck crane are generally composed of the truck chassis, cargo box, power take-off device and crane. Uses Cheng Li is equipped with truck cranes. It is widely used for the hoisting and transportation of infrastructure materials such as municipal construction, coal mine engineering, landscaping, and other equipment. The crane can be operated from left to right, and can be rotated 360 degrees forward and backward, and it can also rotate in all directions.
Sprinkling truck with crane, also known as sprinkling truck with crane, sprinkles water on the vehicle to ensure the operational stability and safety of the on-board crane truck and the vehicle. Sprinklers, sprinklers and other sprinkler functions, the other can be installed on the boom above the height of the work bucket, so that the vehicle with water, shipping (after hanging off the water tank), self loading unloading cargo, high-altitude operations and other functions, is An ideal multi-purpose product. Applicable to gardens, warehouses, docks, ships, railways and other industries, configuration basket can be used for high-altitude operations, can also install grippers, used to snatch all kinds of objects. Features Cheng Li truck crane is based on foreign advanced technology, through absorption and digestion, on the basis of the original to improve and innovate. At the same time also absorbed the advantages of many manufacturers. Overcame the deficiencies of other manufacturers. Product performance is superior, reliable quality.
Cheng Li truck crane is designed according to DIN15018 standard. Cheng Li truck cranes have undergone rigorous inspections from assembly to delivery. Technical performance with crane is one of the most popular crane and transport combinations in the world. It can be used in the low-altitude lifting and rapid shifting within a radius of 10 to 20 meters. Its advantages are: full hydraulic operation, flexible angle, accurate positioning, stable operation, high flexibility, light weight, heavy lifting load, small volume, and free from the constraints of the working environment. After the operation, it can be folded and collapsed, which greatly reduces the space occupation. It is self-suspended, self-unloading, and self-contained. It truly achieves a multi-purpose vehicle and greatly reduces the cost of the user. Therefore, truck cranes have been widely used in construction and construction sites for lifting, shifting, installation and transportation. The tonnage of the hydraulic crane is calculated by the weight of the crane at a distance of 1 meter, so the F1000 is 100 tons and the F380 is 38 tons. Traditionally, the crane weight of a hydraulic crane or a car crane is collectively referred to as the weight of a crane at a distance of about two meters. Such as F1000 and 50 tons of car cranes or F380 and 19 tons of car cranes in the same class, known as 50 tons and 19 tons of cranes. The truck crane basically only needs one driver to serve as the hydraulic crane operator. Currently, the truck crane operation has been developed to use wireless remote control so that the operator can achieve the highest effect in the position where the object is lifted or shifted. After training, the ordinary driver can operate the hydraulic crane or use the wireless remote controller. The wireless remote controller can be additionally equipped with an intelligent lifting system. It can automatically adjust the lifting speed according to different lifting weights. The display screen allows the operator to clearly see the pressure of the hydraulic system during operation. When there is a solid obstacle in the vehicle, the self-detection function will show the solid condition.
General-purpose performance FASSI lorry cranes are used in a wide range and are widely used for heavy lifting at docks and railway stations, as well as large-scale self-assembly and dumping of containers, materials, and equipment. They can also be used to clear roads (transportation vehicles), freight transportation, and freight transfer. And so on, especially in logistics plays an irreplaceable role. The car is also equipped with multiple optional components, such as aerial work platforms, a variety of materials, such as grippers, after selection, can achieve a wider range of operational functions, such as high-altitude operations, emergency fire field rescue. The combination of truck cranes further enhances the function of the hydraulic crane, as it can also transport items to designated locations in addition to the unloading items. This will enable the integration of unloading and transportation costs to be integrated to save costs and construction time. . Although the hydraulic truck lifting crane enters the Chinese market for a short time, the crane lifting crane will have a wider range of advantages due to its advantages of novel design, reasonable structure, smooth lifting, simple operation and other similar products that cannot be replaced. The development of space and market share.


Operation guide 1. The lifting equipment driver must go through professional safety training and be examined and approved by relevant departments. Unauthorized personnel are strictly forbidden to use lifting equipment. 2. Before the work, it is necessary to check whether each operating device is normal and whether the wire rope complies with safety regulations, and whether the brake, hydraulic device and safety device are complete and sensitive and reliable. It is forbidden to run the machine sick. 3. The elevation angle of the lifting boom shall not be less than 30° . The lifting arm should be avoided when the crane is under load. It is forbidden to change the joystick before the lift arm is lifted up and down steadily. 4. The driver and the lifter must closely cooperate with the commander of the signal. Before the operation, the horn must be honking. If it is found that the command is unclear or wrong, the driver has the right to refuse to perform. During the work, the driver must immediately stop the emergency stop signal sent by any person and continue to work until the unsafe factors are eliminated. 5. Must comply with all traffic management rules and regulations and strictly prohibit drunk driving. When driving, smoking, eating, and chat are not allowed. 6. When lifting a heavy object, lift the heavy object about 10 centimeters from the ground. Check that the crane's stability and brakes are flexible and effective, and continue to work under normal conditions.


Common Faults and Precautions Common Faults Analysis and Troubleshooting Analysis of the causes of the phenomenon
Truck crane does not work Pump does not work 1. The power lever is not pushed into place 2. The internal gear of the power take-off box is damaged 3. The drive sleeve between the output shaft of the power take-off box and the oil pump input shaft is damaged 4. The oil pump burns to death 1, push the power lever into position 2, overhaul the power box 3, replace the drive sleeve 4, replace the oil pump
Pump work but no pressure oil 1, tank oil is less than 2, the oil filter is blocked 1, add enough hydraulic oil 2 and clean the oil filter
Loss of lifting capacity, clearly failing to meet regulatory requirements Hydraulic system pressure is too low 1, the system leaks 2, the pressure of the overflow valve is adjusted too low 3, the volumetric efficiency of the oil pump is reduced 1. Check all the pipes and components and take measures to stop the leakage. 2. Check the relief valve setting pressure (The specified relief valve setting pressure is 14Mpa (2~3 tons of crane)/17.5Mpa (5~8 tons of crane) No over-regulation is allowed.) If the relief valve loses pressure regulation, check the relief valve and replace damaged parts. 3, Replace the oil pump.
Lever cylinder 1. The internal leakage is increased due to the damage of the inner ring of the cylinder, 2. The piston in the variable cylinder or the cylinder cylinder of the cylinder has been deformed, causing large internal leakage. 1, replace the damaged seal and piston 2, check the cylinder deformation
Retractable cylinder is weak Same as above Same as above
Winning power Winch plunger oil motor reduces volumetric efficiency Replace the oil motor
After the goods are lifted, they are naturally reduced (more than 2mm/min). It can be clearly seen that the variable piston rod is pulled out, the movable arm and the leg are significantly retracted, and the lifting hook is naturally declining. 1. Luffing cylinder, telescopic oil leaking cylinder, internal leakage of outrigger cylinder 2, failure of balance cylinder and telescopic oil cylinder balance valve 3, failure of bidirectional hydraulic lock on the outrigger 4, lower volumetric efficiency of hoisting motor, hoisting gearbox Internal friction brake disc damage 1. Refer to item 2 above for internal leakage treatment of cylinders, replacement or maintenance of balancing valve 3, replacement or overhaul of two-way hydraulic locks 4, replacement of friction brake pads and motors.
Work operation Note 1): Understanding the size of lifting cargo, find cargo crane from the center position to the center column to view the crane lifting capacity parameters depending on the distance.
2): The lifting capacity (torque) of the crane is fixed and the working radius of the crane is larger. The lighter the goods that are hoisted, the smaller the working radius and the heavier the goods that are hoisted. (Work radius refers to the horizontal distance from the center of the moment to the hook.)
3) Considering the lifting capacity of the crane and the bearing capacity of the chassis size, the larger the beam is, the better the crane is. The larger the crane is, the smaller the chassis is, and it will deform and break the girder. The chassis is small, and the power of the engine is small, affecting the lifting capacity of the crane. So when we consider the 230mm beam, we choose the crane below 3 tons. When considering the 250mm beam, consider the crane below 6 tons. The 280mm beam can select cranes up to 8 tons. Like the rear eight and four chassis can consider less than 10 tons of crane.
4): The crane produced by our company is the introduction of advanced technologies from Japan's Tadano, using imported seals. The steel plate material uses HG60 and HG70 high strength steel plates.
5): In the case of normal operation according to the instructions, our company provides three-packet service for one year free of charge. (consumer parts for three months)
