A Galvanizer came to Electrolift because they had performance, safety, and downtime concerns with their existing hoists. Galvanizing applications are notorious for having issues with the mechanical load brake when there is a constant load on the hook and excessive heat is generated during long lifts causing premature failure. Constant inspections, downtime, contaminants in the oil, safety, and ongoing concerns of hoist failure proved to the galvanizer a new solution was required.
Galvanizing production lines are the industry’s most extreme environments. Your hoist and lifting equipment are working in the heat and corrosive chemical environment and must be made to withstand it all — plus provide safety features critical to worker protection up and down the line. It is not just the galvanizing environment that is hazardous to your hoist, it is the rigorous movement, speed changes, and hang time that takes a toll on a hoist’s performance.
The hoist motor can transmit motion through the gear reducer, but the load cannot transmit motion back through the gear reducer which regulates the lowering speed of the load and ensures the load will not be allowed to free fall. OSHA [1910.179] recognizes this as an approved means of controlled braking.
In galvanizing applications, there is often a constant load on the hook. Worm gears have an inherent design advantage over other gear sets; the worm can easily turn the gear, but the gear cannot turn the worm. In lifting applications, this feature acts as a secondary brake due to limited back drivability. The worm gear sees no adverse effects or wears from a constant load on the hook.
Along with the worm drive gear reducer, the oil shear brake can handle higher cycling, extreme heat, and a high number of starts and stops required for galvanizing applications that are typically multiple shifts 7 days a week. Electrolift hoists are designed to handle this high-duty cycle.
Working with experts who know the industry requirements and hoist manufacturing guidelines is essential for the safety of personnel and longevity of your equipment.
Electrolift’s90 years of experience manufacturing for hazardous environments ensures we know all features and components needed to support a galvanizing operation. AllElectrolift hoists are designed to meet or exceed ANSI standards.
