Frequently Asked Questions
Q: What is the advantage of the L-shaped configuration over a standard inline winch?
A: The L shape allows for a significantly larger drum width without increasing the winch's overall height. This provides greater cable capacity and longer lifting heights in installations where headroom is limited.
Q: How does the large drum size affect cable life?
A: Larger drum diameters reduce the bending radius of the cable, which is the primary factor in cable fatigue. Our 350-500mm drums significantly extend cable service life compared to smaller 200mm drums commonly found on standard winches.
Q: Can this winch be used for suspended seating retraction?
A: Yes, the high load capacity and long travel make it ideal for operating retractable seating systems in multi-purpose venues. Please provide your specific seating weight and travel requirements for proper specification.
Q: What are the options for corrosion protection?
A: We offer standard industrial paint, galvanized components for high-humidity environments, and stainless steel options for corrosive or outdoor applications. All options comply with relevant theatre safety standards.
