Criteria to achieve emission reductions
The following criteria must be met in order for appropriately retrofitted engines to achieve the aforementioned emission reductions:
- The original RTG generator(s) must be equipped with a Tier 0, Tier 1, Tier 2 or Tier 3 engine(s).
- The original RTG must be equipped with a DC bus or the EcoLifting Hybrid System package needs to be equipped with properly sized power frequency converters with common DC bus capability.
- Prior to installation, Konecranes must appropriately size the EcoLifting Hybrid System for the original RTG. In sizing the EcoLifting Hybrid System, a smaller horsepower new Tier 4F diesel engine-equipped generator and battery-equipped energy system must be optimized to satisfy application-specific requirements.
- The EcoLifting Hybrid System includes the components necessary to replace a conventional RTG diesel engine generator and other original power system components as necessary. The EcoLifting components include a new genset equipped with a new Tier 4F diesel engine, exhaust system, battery energy storage system, battery monitoring system, battery cooling and heating system, regenerative brake/energy recovery system, and typically other components as necessary including DC/DC converter, active rectifier, auxiliary converter system, and electrical & mechanical components needed to integrate the system to the crane.
- EcoLifting and the RTG owner must evaluate battery technology options for the specific RTG. Different battery technologies may be preferred due to individual preference and performance requirements, so it is the responsibility of Konecranes and the RTG owner to select a battery technology and size based on these needs.
- The EcoLifting include a battery monitoring system to alarm operators for necessary actions to ensure the proper operation of the batteries.Hybrid System must
- The owner’s manual must include maintenance procedures, safety precautions information and battery disposition information.
- The engine must be operated on ultra-low sulfur diesel fuel (ULSD) of 15 ppm or less.
- The engine used in the EcoLifting Hybrid System must be certified for use in generator sets and meet current model year standards.
