Crown's C-5 Series internal combustion forklift features a power brake system and on-demand cooling
Crown Equipment Corporation has introduced the Crown C-5 Series, a company-manufactured internal combustion (IC) forklift. The Crown C-5 features an industrial engine that was jointly developed with John Deere Power Systems (John Deere), a proactive approach to engine cooling and radiator clearing via an on-demand cooling system, and improved operator visibility, comfort and productivity.
The Crown C-5 industrial engine 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's dual open-core radiator prevents overheating and features separate cooling systems for the engine and the transmission.
Crown alos engineered an optional 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 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.
Control is achieved through Crown Access 1 2 3Ò 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 display screen calls attention to detailed information about engine performance and allows authorized users to adjust performance settings and technicians to troubleshoot components.
The Crown C-5 is also designed to improve drivability. Drivability of the Crown C-5 is gained through:
- Comfort: Crown designed and built its FlexSeat to provide comfort for operators. The Crown C-5 also enhances comfort by redirecting heat and exhaust away from the user during reverse travel, facilitating entry/exit with larger steps, utilizing a contoured seat deck and featuring an unobtrusive push-button parking brake.
- Stability: When the forks and masts are tilted more than 2° forward, the Crown C-5’s interlock feature stops them from rising above free lift. Other intrinsic stability attributes include more mass, dead-engine breaking and steering, hill hold, and ramp speed control.
- Visibility: The Crown C-5’s lower counterweight and LP bottle increase operators’ field of view by five feet compared to other IC lift trucks. These features improve operator confidence and help prevent product damage. Thinner posts and a shorter cowl facilitate an unobstructed view of the forks, while an overhead guard design improves visibility of loads at height.
