HZQ900 High speed railway bridge construction crane

Bridge construction crane 1. 900t large lifting capacity 2. Span: 24m to 32m 3. Special crane for high speed railway

(1)Main feature

safety control system, reliable by using electric and hydraulic. Concentrating the control system with over-pressure protection, and with all position limit devicelight self weight, easy to assemble, especially for curve bridgespan-shift can be finished from 32m to 24m by moving the support legs, very conveniently
