Why APPI:
Allied Power Products, Inc. (APPI) delivers custom lifting solutions for critical infrastructure applications, such as water flow monitoring at dams. Manitoba Hydro sought to replace its aging water flow testing system, which lowers a frame equipped with propellers into the dam to measure water speed and flow.
Monitoring water flow at a dam is crucial for controlling water quality and levels. Manitoba Hydro accomplishes this by lowering a long, thin frame fitted with fan blade-type propellers into a slot at the top of the dam. The speed at which the blades turn is recorded to measure the water flow. This frame structure is lowered into place from a portable gantry equipped with two APPI hoists.
Paul Halipchuk, the Mechanical Engineering Section Head for Manitoba Hydro, was tasked with replacing the old system. He wanted to ensure that the new system had a simple, mechanical means of preventing a catastrophic overload on the lifting gantry. APPI collaborated closely with Halipchuk to design a spring-equipped, vertical lead sheave with overload detection, eliminating the need for an electronic load-sensing system.
After finalizing the design, Wallin Industries won the bid and purchased seven Columbia HD1450-1A34-L-02 gantry hoists with custom lead sheaves – six for installation and one spare. These hoists feature single-speed controls in a NEMA 4 painted steel enclosure, a NEMA 4X hand-held pendant controller, and the custom-designed VLS-6 vertical lead sheave with overload detection.
APPI’s Columbia gantry hoists and custom lead sheaves enhance the safety and reliability of Manitoba Hydro’s water flow testing process. By providing tailored lifting solutions for critical infrastructure applications, APPI continues to support the efficient management of water resources.
