Overview
It features a simple structure, high strength, and easy maintenance, making it suitable for applications with a small inclination angle, such as single-rope winding lifts or well-drilling suspension systems.
Application
It is commonly used in hoisting systems for various vertical shafts and inclined shafts, particularly in temporary suspension systems during main shaft hoisting, auxiliary shaft hoisting, and well-drilling operations. Since it does not require the sheave to move laterally along the shaft, it is especially suitable for scenarios in which the wire rope does not develop a significant deflection angle when wound on the drum, or where strict alignment is required—for example, when used in conjunction with single-rope winding hoists.
Characteristic
When the hoist drum rotates to wind or unwind the steel wire rope, the rope first makes contact with and is seated in the rope groove of the sheave after emerging from the drum, thereby preparing it for subsequent directional changes.
Since the winch shaft is fixed to the rig frame and remains stationary, friction is generated between the wire rope and the rim groove; this friction drives the rim portion to rotate around the fixed bearing housing, converting the linear motion of the wire rope into the rotational motion of the winch.
The steel wire rope extends downward through the overhead pulley after the unit turns, serving to suspend and lift various containers within the shaft, such as cages, bucket cars, or lifting buckets.
Robust construction and heavy-load durability; excellent fatigue resistance and deformation resistance; suitability for long-term heavy-load and high-frequency operating environments; and guaranteed stable and reliable system operation.
