Why APPI:
Creating natural feeding environments for elephants in captivity presents unique challenges that require innovative engineering solutions. The Zoological Society of San Diego approached Allied Power Products, Inc. (APPI) in 2011 with a specialized request: develop elephant feed hoists that could simulate the natural feeding behaviors of wild elephants.
The challenge was multifaceted. Zoo keepers needed to position feeding devices suspended from artificial trees in the elephant habitat, encouraging the animals to reach overhead for food just as they would in their natural environment. This feeding enrichment is crucial for maintaining the physical and psychological health of elephants in captivity.
Through collaborative discussions with the San Diego zoo team, APPI and the Zoological Society jointly determined that the Columbia HF2300 AC hoist would provide the ideal foundation for this unique application. Together, they identified the specific requirements for durability, positioning accuracy, and operational reliability needed in this demanding environment.
Key features of this elephant feed hoist system include:
- Six Columbia HF2300 hoists specifically configured to withstand the robust interactions typical of elephant environments
- Custom upper limit switch assemblies designed for precise positioning of feeding devices
- Reinforced construction engineered to handle the unique stresses of zoo applications
- Reliable 460 VAC three-phase power system for consistent daily operations
The Results
The success of this collaborative solution extends beyond San Diego. Based on recommendations from the San Diego elephant handlers, the Oregon Zoo selected the same Columbia HF2300 units for their new elephant exhibit, demonstrating the effectiveness of this custom-engineered approach.
By implementing APPI’s elephant feed hoists, the Zoological Society of San Diego has significantly enhanced their elephant care capabilities. The system enables natural feeding behaviors that promote both physical exercise and mental stimulation, contributing to improved overall elephant health and well-being.
