DeepSeek answers how to choose a large tonnage folding arm
Well, the user is asking how to choose a large tonnage folding arm crane, and I need to carefully consider this question. Firstly, what are the potential application scenarios for articulated cranes? For example, construction sites, bridge construction, or internal equipment hoisting in factories? Different usage environments have different requirements for equipment. For example, bridge construction may require stronger lateral lifting capabilities, while internal equipment lifting in factories may focus more on crane micro movement and vehicle passability.
Next, users may be concerned about which key parameters to consider when making a purchase. Large tonnage usually means greater lifting capacity, but what is the specific tonnage range? For example, 100 tons, 150 tons, 200 tons, or even larger? In addition, the working radius and lifting height are also important, and these parameters need to be determined according to actual operational requirements. For example, if heavy objects need to be lifted at a longer distance, a larger working radius is required.
Then, the hydraulic system and electrical system are key, and the matching of the hydraulic system determines the controllability and stability of the crane during use. Whether or not a remote control system is equipped also greatly affects the customer's experience when using the crane.
Also, safety features are very important, such as overload protection, torque limiters, anti-collision, anti rollover devices, etc. These safety features are particularly important for large tonnage equipment, as the consequences can be severe in the event of an accident. Users may need to know if the security configurations of different brands are complete.
In terms of brand, well-known brands such as Palfinger, Fassi, and Shaoqi may have better quality assurance, but their prices may also be higher.
In terms of price, users may have limited budgets, but large tonnage equipment is expensive. It is necessary to choose the appropriate timing to place an order, and financing options may also need to be considered.
Regulations and certifications cannot be ignored, such as whether the equipment complies with national announcements and relevant laws and regulations, and whether it has been certified.
Users may also be concerned about actual cases, such as the usage experience of other users and how the equipment performs under similar working conditions. By referring to actual cases, one can gain a more intuitive understanding of the advantages and disadvantages of the equipment.
In summary, when choosing a large tonnage folding arm crane, it is necessary to comprehensively consider multiple aspects such as the operating scenario, technical parameters, hydraulic system, electrical system, safety configuration, crane brand, price budget, regulatory certification, and actual cases. Users need to evaluate and select the most suitable equipment based on their specific needs.
Choosing a large tonnage articulated crane is a high investment and highly technical decision that requires comprehensive consideration of factors such as performance, safety, cost, and service. Here is a detailed step-by-step guide to help you make wise choices:
1、 Clarify requirements and homework scenarios
Analysis of homework environment
• Site conditionsNarrow spaces (such as old factories) may require better vehicle passability, and short wheelbase models with lower overall height can be considered; Bridge construction should pay attention to vehicles with strong lateral lifting capabilities.
• Special working conditionsIn the cold regions of Northeast China, it is necessary to choose customized high-strength steel plates with low temperature resistance.
Lifting task parameters
• Maximum lifting capacityChoose based on 1.25 times or more of the heaviest load, such as frequently lifting 90 tons of cargo within a range of about 5 meters. It is recommended to choose the Shaoqi SQ190T or above model.
• Working radius and heightEnsure coverage of the farthest and highest lifting point.
2、 Core parameters and technical configuration
Lifting performance
• Load Curve TableRequire manufacturers to provide load capacity charts for different arm lengths and angles to ensure coverage of actual working conditions.
• Auxiliary arm or extension armOptional auxiliary arm is required; Multi arm design can enhance flexibility.
hydraulic system
• Handling capabilityAccurate flow control and good micro motion performance are required for small openings.
• StabilityCheck the brand of hydraulic components and whether they are equipped with high-pressure filters to ensure the cleanliness of the hydraulic system.
Electrical system
• Remote controlConvenient control of crane operations and various functions such as startup and shutdown.
security configuration
• Multiple protectionsNecessary overload sound and light alarm protection; Optional torque limiter, anti-collision function, and anti rollover function.
• Emergency equipmentEquipped with emergency stop buttons and other fault response measures.
3、 Crane brand
Brand comparison
• International brandsPalfinger and Fassi are well-established manufacturers, but their prices are high.
• Domestic brandsShaoqi has a high market share and cost-effectiveness, making it suitable for budget conscious customers.
4、 Price budget
Choose the appropriate time to place an order
Spring Festival resumption discountAfter resuming work during the Spring Festival, manufacturers usually introduce preferential policies to start a good year for their operations.
• Off season promotionThe hot summer weather is the traditional off-season for the construction machinery industry, and manufacturers will launch off-season promotional activities.
Exhibition PolicyManufacturers participating in exhibitions will introduce sales policies to enhance the effectiveness of their participation.
budget planning
• Financing planDoes the manufacturer provide installment payments or financing leases, and does the installment payment term meet the demand to alleviate cash flow pressure.
Recommended model reference
• ShaoqiSQ280TFlagship model, with a maximum test lifting capacity of 180 tons, a maximum lateral test lifting capacity of 135 tons, and a three section arm capable of tilting up to 110 tons. The vehicle height is 3.49 meters, suitable for benchmark customers in the lifting industry with sufficient budget.
• ShaoqiSQ6200HLong arm model, seven section hydraulic telescopic arm with a maximum operating height of 26 meters, maximum operating range of 23.76 meters, maximum test lifting torque of 621.6 tons per meter, and a vehicle height of 3.45 meters, suitable for customers who are transforming or expanding their articulated crane business.
• ShaoqiSQ4500Classic model, with a maximum test lifting capacity of 120 tons and the ability to tilt and push 90 tons with one arm, suitable for customers with lower budgets and mainly engaged in traditional tail lifting operations.
Through the systematic analysis of the above steps, combined with professional team evaluation, the selection risk can be significantly reduced, ensuring that the equipment efficiently and safely serves production needs. It is recommended to establish a special team composed of technology, procurement, and finance to develop a detailed procurement evaluation form and make scoring decisions for each item.
