The legs of a headframe slope towards the winch to provide structural stability and support for the heavy loads associated with hoisting operations. This design helps to distribute the forces exerted during the lifting process, reducing the risk of structural failure. Additionally, the sloping legs facilitate the alignment of the hoisting equipment, allowing for smoother operation and better efficiency in transporting materials from underground.

Did the Romans invent the treadwheel crane?

Yes. The Greeks invented cranes with the invention of the winch and pulley hoist. The Romans invented the treadwheel crane. The Romans adopted the cranes of the Greeks and massively improved on them. The simplest one was the trispastos, which had of a single-beam, a winch, a rope, and a block with three pulleys. It had had a mechanical advantage of 3:1, and single man operating the winch could raise 150 kg. The pentaspastos had five pulleys and the polyspastos had a set of three by five pulleys with two, three or four masts. The latter was worked by four men at both sides of the winch and could lift 3,000 kg. When the winch was replaced by a treadwheel, the load could be doubled to 6,000 kg with only half the crew, because the treadwheel had a larger diameter and thus a much bigger mechanical advantage.


How do you calculate loads when using winches?

To calculate loads when using winches, first determine the weight of the load being lifted or pulled. Next, consider any additional factors such as friction, the angle of the pull, and the winch's mechanical advantages. Use the formula: Load = Weight × (1 + friction factor) / cos(angle) to account for these variables. Finally, ensure that the winch's capacity exceeds the total calculated load to ensure safe operation.


What is the veer angle in winching?

The veer angle in winching refers to the angle between the direction of the winch line and the direction in which the load is being pulled. It is important to keep this angle as small as possible to maximize the efficiency of the winching operation and minimize wear on the equipment. A larger veer angle can result in increased friction and potential for equipment failure, as well as making it harder to control the load. Proper alignment helps ensure safety and effectiveness in winching tasks.
