12T Monorail Crane & Feed Rail System

Advanced Crane Technologies replaced an aging 10-ton monorail system with a custom-engineered 12-ton monorail crane designed to U.S. Army Corps of Engineers specifications. The upgraded system features state-of-the-art VFD controls for both hoist and travel motions, along with radio control operation and a pendant backup for flexible use. Load cells were integrated at both dead-end connections to provide overload protection, ensuring safe and precise operation throughout the crane’s range.

The scope also included the installation of a 42’-8” custom spreader beam designed to interface with the dam’s existing stop logs, as well as a 1,033-foot-long monorail feed rail system featuring four continuous 250-amp copper conductor bars. With the entire system spanning 21 spillway gates beneath a state roadway, the project demanded careful planning and execution to overcome extremely limited access and logistical constraints—demonstrating ACT’s ability to deliver in complex environments.
