Sany Heavy Industry STC500 Truck Crane-ton efficient lifting expert 【Technology empowers high efficiency and safety.】 STC500, as the star product of Sany Heavy Industry's K series, is equipped with a 5-section 42.5m U-type main boom, which adopts the optimized design of high-strength steel plate, with the maximum lifting torque of the basic jib reaching 1,886.5 kN/m, and can still lift 10.8t (the average 10t of the same tonnage in the industry) under the working condition of the fully extended boom. The maximum lifting torque of the basic boom is 1886.5 kN・m, and it can still lift 10.8t under full-extension working conditions (the industry average for the same tonnage is 10t).
Q1: What are the core advantages of the STC500 over competitors of the same tonnage? A: Adopting a U-shaped main boom with a large arc section, the weight is 12% lighter than the competitors, but the strength is increased by 15%, and the lifting weight when the 42.5m main boom is fully extended is 8% higher than that of the same tonnage models (e.g., the XCMG QY50K-II with a fully extended boom is 5% lower). It is equipped with the GCP remote management system as standard, which can monitor the status of the equipment in real time (refer to Sany Heavy Industry 2021 Technical White Paper). Q2: How to evaluate the core components of a used STC500? A: Focus on checking the main boom weld (an ultrasonic flaw report is required), hydraulic cylinder sealing (oil seepage ≤0.3 L/month), and engine hours (recommended <12,000 hours; Sany original factory requires an oil change every 500 hours). Q3: What customized configuration is needed for exporting to Southeast Asia? A: It needs to be equipped with a high-temperature cooling system (adapting to a 45°C environment), a multi-language operation interface (supporting Thai/Vietnamese), and ASEAN TISI certification (refer to Sany Heavy Industries Thailand export case). Q4: What are the functions of the GCP system of the STC500? A: It can remotely monitor the position of the equipment, operation data, fault warnings, and support maintenance reminders (such as hydraulic oil replacement cycle automatic push), which reduces maintenance costs by 20% (according to Sany Heavy Industry 2023 user research).
Frequently asked questions
What do you mean by "Figma assets"?
TRANSOCEAN INTERNATIONAL TRADING COMPANY LIMITED is a leading exporter of second-hand construction machinery in China, headquartered in Guangzhou City, Guangdong Province. As the largest supplier of second-hand tower cranes in China, we have integrated nearly 90% of the second-hand tower crane resources nationwide, and established long-term stable cooperative relationships with major domestic and international brands such as Zoomlion, Yongmao, Sanyo, Chuanjian, Potain, and Dahan. We specialize in the foreign trade of second-hand tower cranes and various construction machinery, providing high-quality and comprehensive equipment solutions for global customers.
HOW IS YOUR PRICE COMPARED WITH MANUFACTURERS/FACTORIES?
Relying on the advantage of integrating nearly 90% of second-hand tower crane resources nationwide, as a leading supplier in the industry, we can obtain highly competitive source procurement prices. Compared with new machines from manufacturers, our second-hand tower cranes are more price-competitive and offer much higher cost-performance. Meanwhile, compared with other small-scale suppliers, our large-scale resource integration capacity allows us to provide more favorable quotations for customers, helping them reduce equipment procurement costs to the greatest extent while balancing quality and budget.
Since we have integrated nearly 90% of second-hand tower crane resources nationwide and have abundant in-stock reserves across China, regular models of second-hand tower cranes can be prepared and shipped within 7 days to achieve fast delivery. In contrast, new machines from manufacturers usually require a production cycle of more than 30 days, which cannot meet the needs of customers' urgent projects. Our in-stock advantage can significantly shorten the delivery cycle, ensuring the smooth progress of customers' projects and avoiding construction delays.
HOW SOON CAN YOU RESPOND TO CLIENT INQUIRIES?
We have a professional foreign trade and technical team that responds to customer inquiries 24/7, focusing on serving global foreign trade customers.
