Pulley system for telescoping crane

[anchange]

Hey guys,
I'm trying to figure out how the pulley system / gearing works on something like this -
http://www.chapman-leonard.com/products/telescoping%20crane%20arms/15'%20Telescoping%20Hydrascope.htm

Basically some kind of pulley system make the front 2 telescoping sleeve move in and out in unison as well as making the back counter weight slide to compensate for added or subtracted force on the front end.

In addition the places that the camera is mounted stays level to the base as the crane is arced up or down.

Any ideas?

I would first start by studying the design and mechanics of the telescoping crane. A pulley system is a simple machine that is used to change the direction of a force, making it easier to lift or move heavy objects. In the case of a telescoping crane, the pulley system is used to control the movement of the telescoping arms and the counterweight.

The pulley system works by using multiple pulleys, or wheels with grooved rims, to redirect the force applied to the crane. The front telescoping arms are connected to a series of pulleys, which are then connected to the back counterweight. When the front arms are extended or retracted, the pulleys work together to move the counterweight in the opposite direction, keeping the crane balanced and stable.

To ensure that the camera stays level as the crane is arced up or down, there may be additional mechanisms in place such as a gyroscope or a leveling system. These systems work together with the pulley system to maintain the camera's position and orientation.

Overall, the pulley system plays a crucial role in the functionality of a telescoping crane. It allows for smooth and controlled movement of the arms and counterweight, making it possible to lift and maneuver heavy loads with precision.
