No matter how good the protection and maintenance of the small crane, because there is a need for relative touch movement between the parts that make up the small crane, there is a conflict between the relative touch movement, there is friction when there is conflict, and there is damage due to wear; because of frequent movements There will be fatigue damage; because the shock oscillation will inevitably cause damage to some parts of the crane due to cracks or deformation; due to corrosion aging, etc., some parts will be naturally damaged, etc., and the parts will be invalid when damaged to a certain extent. , may not be used continuously.
Damage such as wear, fatigue, deformation and aging is objective and inevitable. When these damages reach a certain level, it is very risky if the small crane is still used continuously. For this reason, some of the wearing parts of the small crane are damaged. When the unrepairable or uncorrected value is reached, it should be immediately abolished, and it is necessary to replace the new parts in time.
As a small crane driver, it is very necessary to know the common sense of scrapped parts of small cranes in a timely manner. It is also very important to be able to grasp and judge the method of obsolete parts of small cranes. For example, a small crane usually exhibits a large or abnormal sliding when the brake is applied, or an abnormal sliding of the brake during operation, or an abnormally strong sway when rotating, or an abnormal boom swing when the amplitude is changed, etc. When the crane is in the process of abnormal noise, abnormal noise, shock oscillation and leakage, connection, and electric shock,
these may be related to severe wear, fatigue, deformation and aging damage of the wearing parts of the crane. For this reason, as a small crane driver, it is necessary to be vigilant against the above-mentioned damage, then it is necessary to grasp the common knowledge and methods related to the abolition, in order to be able to identify the above-mentioned damage in time, and to be able to deal with the damage caused by the damage. Hand over the relevant personnel in a timely manner to determine which parts should be voided to ensure that the small crane can work safely.

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 intelligent tower cranes, 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 the field of 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 and construction operations.
The company was founded in 2002 with a registered capital of 76 million yuan and a total investment of 300 million yuan.
