When sourcing a small lifting crane, you must prioritize Load Capacity (WLL), ensuring it meets your maximum lifting requirements with a safety factor of at least 1.25x. Pay close attention to the Lifting Height and Arm Reach (Jib Length) to ensure operational coverage. For motorized units, verify the Motor Power (kW) and Lifting Speed (m/min). Additionally, check for 360-degree rotation capabilities and the quality of the wire rope or chain, specifically looking for high-tensile galvanized steel to prevent corrosion and snapping.
