Hoist Lift Speeds Explained
Electric chain hoists with capacities up to 1 ton typically offer lift speeds of 8 FPM (feet per minute), 16 FPM, and 32 FPM. These speeds cater to varying operational needs—from slower, precision positioning tasks at 8 FPM to faster lifting scenarios requiring 32 FPM. Understanding these differences can significantly impact the efficiency and safety of your lifting operations.
Single-Speed vs. Two-Speed Hoists
AFE Crane provides hoists in both single-speed and two-speed configurations. Single-speed hoists operate at a constant lift rate, while two-speed hoists offer greater versatility through dual-speed functionality, typically following a 1:3 speed ratio. Common two-speed combinations include 2 & 8 FPM, 5 & 16 FPM, and 10 & 32 FPM. These options allow operators greater control, enabling slow, precise movements when needed and faster lifts for productivity.
Visualizing Lift Speeds
To better illustrate these differences, we’ve created an informative animation that compares a hoist lifting at 16 FPM versus one at 32 FPM. This visual tool helps operators and decision-makers clearly understand the practical impact of lift speed choices on everyday workflow and efficiency.
Contactor Control versus VFD Control
Another critical factor to consider when choosing a hoist is the control system. Traditional hoist contactor controls provide basic, reliable performance with straightforward operation, while Variable Frequency Drive (VFD) controls offer advanced functionality, including smoother starts and stops, enhanced precision, and increased lifespan of equipment due to reduced mechanical stress.
Harrington Hoist offers an excellent demonstration video highlighting the distinct operational differences between standard contactor control and VFD control systems. Utilizing VFD control can significantly improve operational accuracy, reduce wear, and enhance overall safety and productivity.
