[READi Robust Machine] Excavator Energy Recovery System
Modification solutions for wired electric excavators.
Revolution in Fuel Efficiency for Construction Machinery: Towards Decarbonization with READiX
1. READiX: Diesel/Electric Power Hybrid System A next-generation energy-saving technology that recovers energy from the boom section, where the most energy is consumed during the operation of the shovel, and reuses it as a power source. - Diesel machine: Can save on gasoline costs - Electric motor: Can save on electricity costs 2. READiEPC: Provides essential software solutions for the normal operation of the lid shovel Since the pump is controlled by software, it is possible to operate the equipment normally without errors, even when the diesel engine is removed, which is a common issue. 3. READiEX: Modification of Streamlined Electric Shovel A package that combines the energy recovery system for shovels, READiX, with the software solution for electric shovels, READiEPC.
