Frequently Asked Questions
Q1. Why is the A2FE56 popular on winches?
Compact size plus steady torque under continuous load suits drum drives.
Q2. What is the maximum line pull it supports?
Line pull depends on drum geometry; torque output is about 312 N·m at 350 bar.
Q3. Can it run continuously at rated pressure?
Yes, with proper case drain and cooling it handles sustained rated duty.
Q4. Is a marine-grade version available?
Corrosion-protected variants can be supplied for saltwater exposure.
Q5. How do I control speed?
Speed follows input flow; a simple flow control valve is usually enough.
Q6. What spares are commonly kept in stock?
Seal kits and bearings for the most common codes are held in stock.
Q7. Do you offer fleet pricing?
Yes, program pricing applies for vessels or fleets rebuilding multiple units.
Q8. Can it be used for braking?
With a suitable counterbalance or brake valve in the circuit, yes.
