2 2 Panama Canal Rolling Gates

3 Purpose of PIANC 173 The aim and purpose of this working group report is to determine technological guidelines for design, fabrication, construction, operation and maintenance of both rolling gates and movable bridges as outlined in the Terms of Reference. The focus of the report is on mechanical and electrical design features of rolling gates and movable bridges rather than structural design. Another primary objective of the Working Group is gathering the experiences of the working group members and providing lessons learned and best practice in the design and operation and maintenance for both rolling gates and movable bridges. 3

4 Terms Reference Objective of the Working Group: Establish a working group of mechanical, electrical and constructive engineers to assemble lessons learned from navigation bridges and rolling gates and their operating systems and to give recommendations for future design. Final Product: The working group report provides a comprehensive summary of design solutions, lessons learned, best practices and recommendations that can be incorporated into future bridge and rolling gates operating machinery and constructive designs. 4

9 PIANC 173 New Locks Report discusses new locks at Panama Canal, Kieldrecht, and Imjuiden and the new rolling gates for these locks Currently, rolling gates are a nearly unanimous choice in navigation locks with chambers wider than about 40 m. Panama gates utilize a removable lower carriage and incorporate a compression column 9

12 Rolling Gate Machinery Most rolling gates today utilize a wire rope winch system for opening and closing the gate Chain systems are also used to drive rolling gates and the older Bremerhaven Sea Locks utilize chain drive Most of European locks utilize redundant gates on both ends of lock as does the new Panama Canal locks Wheelbarrow vs Classical Design Some rolling gates utilize a hydraulic system and rack and pinion systems not common 12

13 Antwerp Sea Locks Belgium has extensive design experience with rolling gates and sea locks Largest locks in the world Utilize wheelbarrow type design for rolling gates One carriage is on bottom of gate and the other carriage is on top (like a wheelbarrow) Utilize buoyancy chambers Mixers are utilized to keep sediment entrained as gate rolls across the lock chamber 13

15 Movable Bridges Discusses multiple types of movable bridges and the associated drive systems Drive systems are similar between movable bridges and rolling gates Swing bridges Vertical lift bridges Bascule bridges 15

17 Rolling Gates and Movable Bridges Some of the electro-mechanical components common to both rolling gates and movable bridges include electric motors, gear reducers, open gearing, brakes, wire rope and rope drums, couplings, and automated control systems. Many of the electrical and control components of movable bridges and rolling gates are the same. A drive system failure of either rolling gates or a movable bridge has the potential to impact waterway navigation traffic. Ship impact considerations are also similar between rolling gates and movable bridges. 17

19 Rolling Gates and Movable Bridges Remote operation is common between rolling gates and movable bridges Rolling gates are often used as bridges for vehicle traffic Standard of reliability is different between rolling gates and movable bridges Rolling gates often use buoyancy tanks to reduce the weight bearing on the carriages and rail tracks and for transport. Movable bridges typically are counterweighted to reduce the force needed to lift the bridge or to equalize forces on a bearing as the bridge is raised and lowered or swung 19
