Why APPI:

When Unique Metalcraft Inc. needed a reliable solution for regular maintenance of oil/water separators on the Columbia River, they faced a unique challenge: creating a lifting system that could operate consistently in harsh outdoor conditions while ensuring precise, safe handling of heavy filtration equipment.

The demanding environment of the Columbia River requires equipment that can withstand constant exposure to moisture, temperature fluctuations, and corrosive elements. Additionally, the separator’s regular maintenance schedule demanded a hoist system that could provide dependable service with minimal downtime.

Through collaborative discussions with Unique Metalcraft Inc., Allied Power Products, Inc. (APPI) and the customer jointly determined that a specialized two line dam hoist would be the ideal solution for their specific operational requirements.

Key features of this jointly developed dam hoist system include:

1. Stainless steel grooved drum and fasteners – specifically selected to resist corrosion in the river environment, ensuring long-term reliability as identified during customer consultations.
2. Single drum, two-wire lifting arrangement – this configuration prevents the separator from becoming cocked or jammed during lifting and lowering operations, addressing a key safety concern raised by Unique Metalcraft Inc.
3. Right angle gearbox design – allows for compact installation in the limited space available at the river site, meeting the customer’s spatial constraints.
4. Custom rotary limit switches – provide precise control and safety stops tailored to the specific lifting requirements of the oil/water separator system.
5. Weather resistant components – all electrical and mechanical elements are designed to withstand continuous outdoor exposure on the Columbia River.

This custom-engineered system offers Unique Metalcraft Inc. several operational benefits:

• Reliable lifting and lowering of heavy separator components for routine filter mainten
• Enhanced safety through the dual-wire, anti-jamming design
• Reduced maintenance costs due to corrosion-resistant construction
• Improved operational efficiency with precise positioning control
• Long-term durability in challenging river conditions

By implementing APPI’s Columbia two line dam hoist system, Unique Metalcraft Inc. has significantly improved their maintenance capabilities for critical water treatment infrastructure. The system’s robust construction and application-specific design features, developed through close collaboration with the customer, ensure safe and efficient operations in the demanding Columbia River environment.

Why APPI: 

When Portland General Electric (PGE) needed to enhance their fish ladder flow control system at Willamette Falls, they turned to Allied Power Products, Inc. (APPI) for a solution. The challenge was to improve the efficiency and safety of managing flow levels for endangered salmon, steelhead, and lamprey eel species migrating to their spawning grounds.

Previously, PGE used a manual system involving multiple chain hoists to lift and place “stop logs” for flow control. This process was not only time-consuming but also potentially dangerous, requiring access through an elaborate tunnel system under the falls.

APPI’s solution centered around the Columbia H21500-4A17-L-00 hoist, specifically engineered for the unique requirements of the fish ladder environment. Key features of this flow control hoist system include:

1. Robust line pull capacity, suitable for heavy-duty operations in challenging conditions.
2. Precision control with dual multi-turn potentiometers for accurate position locating.
3. A custom NEMA 4X control panel with a variable frequency drive, ensuring reliable performance in wet conditions.
4. User-friendly interface with UP/DOWN buttons and LED indicators for gate positions.
5. Future-proofing with a LOCAL/REMOTE switch for potential remote control integration.

By implementing APPI’s Columbia flow control hoist, PGE has significantly improved their fish ladder management process. The new system offers several benefits:

• Increased efficiency in adjusting gates and stop logs
• Enhanced safety for operators
• Improved accuracy in flow control
• Faster response times for flow adjustments
• Better adaptability to changing environmental conditions

This project showcases APPI’s expertise in designing custom solutions for unique environmental challenges. By leveraging their previous experience with fish-related projects, APPI was able to create a hoist system that not only met PGE’s current needs but also anticipated future requirements.
