The car crane is mainly composed of three parts:
1. The lower part of the vehicle (also referred to as the chassis) small tonnage car cranes generally use standard truck chassis, and the large and medium tonnage car cranes use special special car chassis.
2. Slewing bearing part. It is a device that is mounted on the walking portion of the getting off and is used to support the upper swivel portion. It transmits various loads of the rotating part of the upper vehicle to the undercarriage of the running part of the vehicle through the support wheel or the roller, so as to keep the turning part of the upper car rotating correctly and flexibly around the rotation axis, and ensuring that the turning part of the boarding vehicle is sufficient Stability.
3. The turning part of the car (also known as the rotary machine). The rotary machine is equipped with other devices such as a lifting mechanism, a luffing mechanism, and a rotary mechanism operating room.
The car crane has good maneuverability and flexibility, can be quickly transferred from one work location to another, and the preparation time required for transfer and work is short, which can improve the utilization of the crane more fully. Automobile cranes are widely used in the installation of loading and unloading machines in construction sites, open-air yards, warehouses, stations, terminals, workshops, etc., and are also used to construct the bottom concrete of hydraulic structures in hydropower projects, and are also particularly suitable for working points. Dispersed, sporadic loading and unloading and installation of goods.
Xuzhou Jiufa Construction Machinery Co., Ltd. is a national high-tech enterprise specializing in R&D, manufacturing and operation of rough-terrain cranes and other construction machinery products. The company has a complete technical quality assurance management system, and passed the ISO9001 quality management system, ISO18001 occupational health and safety management system certification and CE certification, GOST certification. As the “Engineering Technology Research Center for Off-Road Tire Lifting Equipment” approved by the Science and Technology Department of Jiangsu Province, the company has established and maintained a long-term cooperation relationship with Jilin University. At present, the company has 56 patented technologies, including 15 invention patents and 41 utility model patents. The products mainly include QRY series off-road cranes, QY series truck cranes, DGY series multi-functional pipelayers, TQK series fast-moving self-erecting smart tower machines, self-loading and unloading intelligent sanitation vehicles and key parts of engineering machinery. Among them, DGY series multi-functional pipelayer and self-loading intelligent sanitation car have won global invention patents. TQK series fast moving self-erecting smart tower machine is the first product in China.
The QRY series of cross-country cranes independently developed by the company was recognized as “high-tech products” by the Science and Technology Department of Jiangsu Province and listed by the Ministry of Science and Technology as “National Torch Plan Industrialization Demonstration Project”. This series of models uses computer control technology, CAN bus technology, hydraulic pilot proportional control technology, electronically controlled shifting stepless shifting technology, four-wheel steering positioning detection technology and safety image monitoring system, making it a high-tech electromechanical Instrument integration products. This model adopts self-made special off-road chassis, imported axles, gearbox, four-wheel drive and synchronous steering, with high power and high passability. This model is fully hydraulically configured for continuous stepless shifting, crab walking, and heavy-duty driving. This model is suitable for construction in complex road conditions such as mountains and mines. It is also suitable for operation in small sites such as ports and freight yards. It can meet the special needs of different users in various industries for on-site lifting operations.
The company was founded in 2002 with a registered capital of 76 million yuan and a total investment of 300 million yuan.
