When selecting a small lift crane (such as a mini gantry, jib, or portable floor crane), the most critical factor is the Rated Lifting Capacity. Always verify that the Safe Working Load (SWL) exceeds your heaviest intended lift by at least 20% to ensure a safety margin. Additionally, examine the Lifting Height and Span; for telescopic models, ensure the structural integrity is maintained at maximum extension. Pay close attention to the Motor Power (for electric models), prioritizing pure copper motors over aluminum for better heat dissipation and longevity, and check if the Wire Rope is anti-rotation galvanized steel to prevent load spinning.
