Product details:
Model:QY75K
This product was manufactured in April 2018, QY75K, with 5 arms, auxiliary arms, original paint, and a counterweight of 12 tons
Working principle:
There is a rotating drum underneath the boom, which wraps around a steel wire rope. The steel wire rope passes through a pulley on the top of the next boom, pulling the previous boom out, and so on. When retracting, the drum reverses to retrieve the steel wire rope, and the boom retracts under its own weight. This rotating drum is driven by a hydraulic motor, so you can see two oil pipes, but don't mistake them for oil cylinders.
In addition, some car cranes have plunger type oil cylinders installed in their telescopic arms, but this type of application is extremely rare. Due to the high cost of multi-stage plunger type oil cylinders and the elastic bending of the lifting arm under load, it has a significant impact on the service life of the oil cylinders.
