How do I calculate the crane span and height I need?
<p>To calculate crane span, measure the distance between the centerlines of your runway rails (or building columns if using a gantry). For overhead crane, the span is biasanya 1-2 meters less than the building width to allow for rail clearance. For derek gantry, span equals the rail gauge plus wheelbase. Required hook height is the vertical distance from floor to the highest lifting point, plus 0.5-1 meter for load clearance, sling length, and hook travel. Our engineers can verify your dimensions—we've supplied cranes from 0.5T to 150T across 60+ countries.</p><p>For a precise quote, send your building width, rail height, and max lift height to our WhatsApp +86 19392777259. We respond within 4 hours with a custom span/height recommendation and 30-45 day production timeline.</p>
