ASE Crane System

Our innovative Advanced Safety Electronics (ASE) Phase 4 control system has elevated jobsite safety and performance.

We’ve combined crane, body, and chassis operations with functional safety using a network of switches and sensors to communicate data. Advanced Safety Electronics reduces the risks of working in hazardous conditions, takes the guesswork out of crane operation with automated protection features, and gives you information to make safe decisions. Based on the robust J1939 Protocol, we can also incorporate the telematics data into your fleet management solution.
