technical field

The utility model relates to the technical field of elevator sheaves, in particular to a high-strength elevator sheave.

Background technique

The elevator sheave is a kind of pulley that can be hung with a wire rope. Considering the weight of the elevator itself, the elevator sheave is usually made of cast iron to achieve high strength and long service life. Because the elevator is vertically lifted, the elevator sheave needs to be installed with the rope. The wheel stands up and is then installed on the rotating shaft. However, the weight of the cast iron material is large, which makes the overall weight of the elevator sheave extremely large. During installation, there is no hoisting device in the elevator shaft due to space constraints, which often requires multiple manual coordination. In view of this, the utility model proposes a high-strength elevator sheave.
