The result is the Crown C-5 industrial engine, which features a cast iron head and larger, more robust components that are designed to prevent overheating and warping while extending the product’s lifespan to twice that of existing IC trucks. Crown says the C-5’s horsepower and low-end torque are the most powerful in the IC market, improving performance during acceleration, incline-loaded travel, and carrying or pushing heavy loads.
Research showed that another challenge associated with IC lift truck engines was overheating. Crown addressed this challenge with a dual open-core radiator with separate cooling systems for the engine and transmission. This is a standard feature on the Crown C-5.
Further, Crown engineered an optional and exclusive On-Demand Cooling (ODC) system that automatically clears itself of debris and provides precise cooling to effectively manage heat in intense and dirty environments. Each time a user starts the Crown C-5, the ODC system’s radiator-clearing feature reverses the fan direction to dislodge any debris. This drastically reduces the frequency of radiator cleanings, which reduces maintenance costs and increases uptime. In addition, the ODC system adjusts its fan speed based on engine temperature, and the strategic placement of the fan improves cooling efficiency by pulling air evenly through the radiator rather than pushing the air as most other systems do.
Crown says operators spending most of their day on the Crown C-5 will notice superior drivability advantages in the form of control, comfort, stability and visibility. Control is achieved through Crown Access 1 2 3 System Control, which is the electronic system that manages all truck functions and proactively facilitates two-way communication with the operator. The technology also plays a critical role in keeping the operator out of unsafe conditions.
The system’s on-board display uses Crown eSmart Accurate Fuel Tracking to alert the operator when the system senses 16 minutes of remaining fuel time. This technology increases productivity by reducing the time spent unnecessarily changing fuel tanks.
The Crown C-5 is also designed to improve drivability, which is the confidence and control operators require when maneuvering or handling a load.
Another challenge facing the IC lift truck market has been the high cost of frequent service and maintenance issues. In its first 2,000 hours of operation, the Crown C-5 is projected to average just 76 routine tasks. Crown says this performance improvement delivers reduced downtime and lowered out-of-pocket maintenance costs compared to traditional IC trucks.
For example, the self-adjusting power brake system on the Crown C-5 has fewer moving parts and a 90 percent larger brake pad surface than traditional drum brakes, which translates into a lifespan that is three times longer and requires 93 percent fewer maintenance checks, says Crown.
