What is the better elevator drive system hydraulic, winding drum, counter weighted chain drive or friction drive?
“Better” is in the eyes of the customer! Each system has advantages, applications and price points. Winding drums and hydraulic drives have been the backbone of the industry for years. While being reliable and of aaverage cost, they do require a separate machine room, hydraulic fluids, and some special anchoring. Counter-weighted chain drives are shaft contained, don’t require fluids, and are very cost competitive. Friction drives are the newest technology. The drive system and controller are contained within the hoistway. They are somewhat more expensive, but are the ultimate in smooth and quiet operation. 13.
