1. Safety & Compliance (Non-Negotiable)
Certifications: Confirm CE / ISO compliance (and local standards like GB for China use) to avoid unapproved units.
Safety Features: Ensure it has tilt protection, overload alarm, emergency stop/lowering, guardrails, anti-slip platform, and pothole protection bars (for outdoor use).
2. Application & Parameter Matching
Working Height: Distinguish between platform height and working height (platform height + 2m). Choose based on your maximum required reach.
Load Capacity: Rated load (230kg/320kg/450kg) must cover operator + tools + materials with a safety margin.
Dimensions & Maneuverability: Check body width/length for doorways/elevators, turning radius (zero-turn preferred for tight spaces), and platform extension options.
Gradeability: Ensure the lift can handle ramps or slight slopes (≥25% recommended for versatility).
3. Core Configuration & Durability
Tires: Non-marking solid tires for indoor use; heavy-duty, wear-resistant tires for outdoor/rough ground.
Scissor Structure: High-strength manganese steel arms with quality welding.
Hydraulic System: Reliable cylinders and seals to prevent leaks and ensure smooth lifting.
Battery & Power: Industrial lead-acid or lithium batteries. Confirm runtime per charge and maintenance requirements.
Control System: Responsive joystick operation with fault diagnosis codes for easy troubleshooting.
4. After-Sales & Service
Warranty: Clear terms for the whole machine (typically 1–2 years) and key components (motor, hydraulics, battery).
Parts Supply: Ensure the supplier has stable spare parts stock to avoid long downtime.
Training & Support: Check if they offer operation and safety training.
Maintenance Cost: Understand routine maintenance (hydraulic oil change, battery service) and associated costs.
5. Additional Pitfalls to Avoid
Don't choose based solely on low price: Cheap models often cut corners on safety features, materials, and components, leading to high long-term risks and costs.
Confirm use limitations: Some models are only for flat, hard floors and not suitable for rough or uneven construction sites.
