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(2)main technical parameters
