Trolley Case vs Regular Case: Which is Right for Your B2B Application?

Direct answer: Trolley cases (with retractable handle + inline-skate wheels) are best for B2B applications where the user carries the case for > 50 meters or transports > 5 kg of equipment. Regular cases (handles only) are better for short carries (< 50 m) and lighter loads. Kexin 9系 and 拉杆 series are trolley-format; 0系, 1系, 6系, 7系, 8系 are regular format.

Trolley Cases (Kexin 9系 HD + 拉杆)

Features: retractable handle extends 950-1000mm, 2 inline-skate polyurethane wheels, side handle for lifting, top handle for grabbing. Weight empty: 2.5-8.5 kg. Capacity: 5-50 kg payload. Best for: traveling sales engineers, mobile medical/diagnostic teams, exhibition/trade show transport, defense logistics, drone field operators.

Regular Cases (Kexin 0系/1系/6系/7系/8系)

Features: 2-3 fixed handles (top, side, front), no wheels. Weight empty: 0.6-3.5 kg. Capacity: 5-30 kg payload. Best for: equipment storage, fixed-location use, short transport (office, workshop, vehicle trunk), defense and aerospace racking systems.

Decision Framework

• Choose trolley if: user carries > 50m, payload > 5 kg, frequent travel, mobile workstation
• Choose regular if: stationary use, payload < 5 kg, racking/storage, vehicle transport only, rugged defense environments

Cost Difference

Trolley cases are 30-50% more expensive than regular (USD 95-180 vs USD 38-95 for similar size). Wheel replacement: USD 20-30 per set (replaceable).
