Часто задаваемые вопросы
Q1: What is the FAA20780R1 pulley used for?
A: It is the deflection pulley of the Otis Gen2 lift, and it is the belt pulley block of the suspension system. It guides the traction belts and acts as a deflection point, so the belts follow the correct path between the traction machine, the car and the counterweight. It is fitted on the car or on the counterweight, depending on the roping of the installation.
Q2: What other names is this pulley known by?
A: The pulley is written FAA20780R1, and it is also written FAA 20780 and FAA20780 R1. In the market it is sold under several names, and it is also known as the steel belt pulley, the steel belt guide wheel, the deflection pulley, the deflector sheave, the diverting pulley and the belt pulley block. Please send us a photo if your supplier uses a different name for the same part.
Q3: Which Otis lifts is it used on?
A: It is used on Otis Gen2 lifts, which run on coated steel belts instead of wire ropes. The Gen2 system uses several belts in parallel, and the pulley must match the number of belts on the lift. Please confirm the lift model and the belt count before ordering.
Q4: How do I know which version of the pulley I need?
A: The version of the FAA20780 pulley is identified by the number of belts it carries. The FAA20780R1 is the version for 3 belts, and it is listed with a 55 mm width, while the FAA20780V1 is the version for 2 belts. Please confirm the belt count and the width on your original pulley, because a different belt count is a different part.
Q5: What is the difference between the FAA20780 and the AAA20780 pulleys?
A: FAA20780 and AAA20780 are two different pulley series of the Otis Gen2 lift, and the two part number families are not interchangeable. The FAA20780 series is the deflection pulley family, and the versions in this family are identified by the number of belts. The AAA20780 series is the steel belt guide wheel family, and the versions in this family are identified by the number of grooves, with models from 2 grooves up to 5 grooves. Because the two prefixes look similar, please compare the full part number on the original part before ordering.
Q6: How can I confirm this pulley matches my lift, and do you supply other Otis Gen2 belt parts?
A: Please compare the part number, the belt count, the width, the shaft diameter and the slot position of the shaft with your original pulley. Older versions of these pulleys are slotted on both ends of the shaft, while the current versions are slotted on one end only, so please also check the shaft before ordering. If you are not sure, please send clear photos of the pulley and its label, and our technical team can help identify the correct part. We also supply the other FAA20780 and AAA20780 pulleys, the Otis Gen2 steel belts and other Otis Gen2 traction and suspension parts.
