Why APPI:  Monitoring the water flow at a dam is an important process to control water quality and water levels.  At Manitoba Hydro, this process is accomplished by lowering a long, thin frame equipped with fan blade-type propellers into a slot in the top of the dam, which records the speed at which the blades turn to measure the water flow.  This frame structure is lowered into place from a portable gantry equipped with two of our hoists.

Tasked with replacing the old system, Paul Halipchuk, the Mechanical Engineering Section Head for Manitoba Hydro, wanted to be sure the new system had a simple, mechanical means of preventing a catastrophic overload on the lifting gantry.  Working closely with him, we designed a spring-equipped, vertical lead sheave with overload detection that did not require an electronic load sensing system.

Once the design was complete, Wallin Industries was awarded the bid.  They ordered 6 of the gantry hoists and custom lead sheaves for installation and one extra unit as a spare.
