Q1: What is the core difference between QY70KC and QY70K?
A: QY70KC is upgraded to 48m five-section U-type main boom (44.5m for QY70K), lifting height is increased to 70m (including jib), the cab is optimized for dust and noise reduction, and the hydraulic system adopts the G-generation dual-variable pumps + post-valve compensation technology, which improves the working efficiency by 15%.
Q2: Can it be used for wind power equipment lifting?
A: The maximum lifting height of the standard jib is 70m, and it can be used to lift 1.5MW wind turbine tower (36m range lifting weight 1.6t), and it needs to be equipped with wind power special spreader and wind speed monitoring system.
Q3: How to assess the value of used equipment?
A: Focus on checking the main boom weld (no cracks), hydraulic cylinder oil seepage, engine hours (≤15,000 hours is recommended) and maintenance records (e.g., replace hydraulic oil every 1,000 hours).
