Advantage of a sheave wheel in a shaft headgear

The Benefits of a Sheave Wheel in a Shaft Headgear

Control and Efficiency: One sheave in the headgear allows for the use of a double drum winder, which provides better control over the hoisting process. Double drum winders are easier to control, brake more effectively, and are overall more efficient than single drum winders.

Time-saving: Using a double drum winder means that two skips or cages can be operated simultaneously, saving time during the hoisting process. Additionally, the winder can be clutched to perform faster shift transport, further increasing efficiency.

Safety: In the event of a malfunction or trip-out during hoisting, a single drum winder can be slow, unbalanced, and pose a safety risk. On the other hand, a double drum winder provides more stability and control, with two sets of brakes that the driver can rely on to prevent accidents.

Emergency Escape: A single sheave could also mean a shaft with a single compartment, limiting escape options in case of emergency. Having multiple winders with two or more sheaves ensures there are alternative escape routes such as ladders or stairways.

Overall, the use of a sheave wheel in a shaft headgear, particularly in conjunction with a double drum winder, provides significant benefits in terms of control, efficiency, safety, and emergency preparedness.
