Q: There is a wide range of Harken pulleys. What if the one I need isn't certified?
A: Harken can CE certify additional pulleys in response to demand. If you need a pulley that is not listed, please contact email@example.com
Q: Can Harken pulleys be used with wire rope?
A: This depends on the sheave material. Pulleys with aluminum sheaves can be used with wire rope; however, the pulley's working life will be less because of increased wear on the sheave. Our wire pulley range and Black Magic pulleys sizes 75 mm or larger have aluminium sheaves.
Q: Are Harken pulleys suitable for human suspension?
A: No, they are not certified for human suspension
Q: Are Harken CE pulleys marked with the working information?
A: Yes. Each pulley is marked with a tamper-proof sticker specifying block type, maximum rope diameter, max rated load, breaking load, serial number, and the manufacturer’s mark clearly visible. Every pulley is sent with a manual detailing safe usage and warning information.
Q: What does "max rated load" mean?
A: This is the maximum load for which the equipment is designed by the manufacturer.
