Design of Large Tonnage Elevator Sheave Block

Abstract

Large tonnage elevator lifting heavy cargos have been more and more widely used. In order to ensure the normal operation, maximize the function of a cargo elevator, avoid safety accidents, improve the use efficiency, achieve cargo elevator standardization, optimization design is more important on the traction sheave block structure of large tonnage cargo elevator, we seek to find a breakthrough from the common traction sheave block structure and accordingly the sheave structure can own a better performance in the application of large tonnage traction elevator. In this paper with sheave block rated load 10,000 kg, the rotary speed 60 rpm, pitch diameter 640 mm, equipped with wire rope 8 strands Φ16, rope groove spacing 25 mm, the parameters of the sheave block are given to design the sheave structure suitable for large tonnage elevator for load capacity 15–20 ton.
