A: All listed models operate on a rated voltage of 220/240V and a frequency of 50/60Hz, making them suitable for standard industrial and construction power configurations.

A: The LZ-1317 model delivers the highest specifications in this range, featuring a rated input power of 2000W and an impact force of 60 Joules, alongside a load speed of 1900r/min.

A: The impact energy ranges from 45J (on the LZ-65A and LZ-120 models) to 50J on the majority of intermediate models, reaching a maximum of 60J on the heavy-duty LZ-1317 model.

A: Yes, most models maintain a stable load speed of 1800r/min to ensure efficient operations, with the exception of the high-power LZ-1317 model which operates at 1900r/min.

A: The power options range from 1240W on the entry-level configurations up to 2000W on the most powerful model, allowing users to match tool power directly to their workload requirements.
