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).
