### YYQ‑120A
Output force: 60 kN; stroke: 13 mm; crimping range: 10–120 mm²; compatible die sizes: 10, 16, 25, 35, 50, 70, 95, and 120 mm²; crimping method: hexagonal compression; packaged in a plastic case; overall length: 415 mm; weight: 3.2 kg; lightweight body, suitable for working with small-cross-section cables.

### KYQ‑300
Force: 100 kN, stroke: 22 mm, crimping range: 16–300 mm²; Compatible die sizes: 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, and 300 mm²; crimping method: hexagonal compression; packaged in a plastic case; overall length: 490 mm; weight: 6.3 kg; suitable for installing medium-cross-section cables in power distribution applications.

### KYQ‑400
Force: 105 kN; stroke: 32 mm; crimping range: 50–400 mm²; Compatible die sizes: 50, 70, 95, 120, 150, 185, 240, 300, and 400 mm²; crimping method: hexagonal compression; packaged in a plastic case; overall length: 530 mm; weight: 6.2 kg; with ample stroke, it can handle large-cross-section high-voltage cables.

### Overall Summary
All three models share the same crimping process and storage method. As the compatible cable cross-section increases, the unit length, force, and stroke length increase accordingly. Among them, the YYQ-120A offers the best portability, while the KYQ-400 is capable of handling the crimping requirements for the largest cable specifications.
