Product Description Product Description The upper and lower support of tower crane is an important part of tower crane, and they each bear different functions and structural characteristicsThe upper support is an important component of the top of the tower crane, which usually includes the upper support body, the reducer mounting cylinder, the drive motor and the drive gear. The reducer mounting cylinder is arranged vertically, the top is provided with a drive motor, the output shaft of the drive motor is inserted into the reducer mounting cylinder, and the output shaft is provided with a drive gear. The lower support is the part of the tower crane connected with the foundation, which bears the weight of the whole machine and the load during operation. The structure of the lower support usually includes the upper cover plate, the outer cylinder, the main chord, the rib plate and the wing plate.The upper cover plate is provided with a middle opening, the upper end of the shell is arranged in the middle opening, and a plurality of main strings are arranged on the peripheral side of the shell at equal circumferential intervals. The main strings are tubular and the axis is parallel to the axis of the shell.

Slewing support: connecting the on-board and off-board structure to achieve 360° rotation. Track chassis: including track plate, drive wheel, support wheel, etc., to provide stable walking and ground support. Cab and upper frame: Integrated operation control system and power plant. Hydraulic cylinders and pins: Key connections that drive the movement of each component.Q: How does the material of the structural part affect the performance?A: The high-quality structural parts are made of high-strength wear-resistant steel (such as the tooth seat plate and the side plate of the rock bucket) to resist wear; Key parts (such as slewing support) adopt integral forging process to avoid welding deformation and improve strength.Q: How to select suitable excavator structural parts?A: Model matching: It is necessary to specify the brand (such as Carter, Xugong, etc.) and model (such as PC200, PC300) of the excavator, and the size of the structural parts of different models is greatly different. Working condition adaptation: For example, long arm or heavy bucket should be selected for mine operation; A wide track plate is recommended for soft ground to reduce pressure. Accessories compatibility: Pay attention to the hydraulic cylinder, pin and other interface specifications are compatible with the original system.Q: Do structural parts support custom modification?A: Yes. Some manufacturers provide extended arm modification, track chassis widening and other services, and can customize non-standard accessories (such as special size bucket sleeve).Q: What should I pay attention to in the daily maintenance of structural parts?A: Lubrication maintenance: regularly apply butter to the pin shaft and slewing support to prevent rust and wear. Cleaning inspection: clean up the sediment after operation to avoid corrosion; Check welds and bolts regularly for loosening. Hydraulic system maintenance: Avoid using gasoline to clean rubber parts when replacing seals to prevent aging.Q: How to remove common faults of structural parts?A: Crack or fracture: mostly due to fatigue or overload, need to stop to repair and check the design rationality (it is recommended to use finite element analysis to optimize the structure). Hydraulic leakage: Check the seal for wear or improper installation, and ensure that the dimensional tolerance meets the requirements when replacing it. Bucket tooth wear: Regularly replace removable tooth holder, use high hardness alloy material to extend life.Q: What are the process characteristics of high-quality structural parts?A: axle sleeve pressing process: through the seat hole step design to simplify the process and improve the positioning accuracy. Welded structure optimization: The cab bracket is formed with bent veneer to reduce welds and improve safety. Precision machining: spool valve sleeve and other accessories need to strictly control the surface finish and form tolerance.Q: How to identify the quality of structural parts?A: Material testing: The supplier is required to provide material reports (such as hardness and tensile strength of wear-resistant steel). Process verification: check whether the weld is uniform and has no porosity; Forging parts must have no interlayers or cracks.Q: How to avoid structural damage during operation?A: Load control: Avoid overload of hydraulic system (such as forced excavation of hard rock resulting in tooth fracture). Specifications for the use of accessories: When installing accessories such as hydraulic shears, ensure a safe distance from the cab. Ground adaptability: Soft ground should be laid steel plate to prevent track sinking.
