Actuators in Excavators
Construction workers working alongside an excavator that is digging up dirt.
How actuators work in excavators
The linear actuators in hydraulic excavators perform the vital role of controlling the extension and retraction of the arm and bucket of the excavator.
The large amount of power brought by the linear actuator allows the excavator to exert a large amount of force in order to unearth large amounts of soil. It is essential for controlling the excavator in a precise manner and is vital to the excavator and other construction equipment for its high power, quality, and reliability.
Ergonomics
Linear actuators are extremely powerful, enabling hydraulic excavators to perform much more work than humans or many other devices can. They are very versatile in the sense that they can be applied to many different types of jobs and projects.
Above all, linear actuators in excavators are reliable and ensure safety around the workplace. It provides much efficiency since it is designed to prevail through repetitive mechanical movements and support heavy loads which humans are otherwise incapable of doing (reducing workplace injuries).
Two excavators harvesting dirt from unique terrains: one from land and one from water.
Comparison of different types of Excavators
Hydraulic Excavators
The standard type of excavator that uses powerful hydraulic linear actuators to operate the arm and its attachment (such as a bucket or claw). Ideal for large-scale digging projects held on land.
Dragline Excavators
A type of excavator that uses a pulley system to operate the claw of the excavator allowing it to reach depths of more than 65 metres, making the device suitable for deep digging projects. It uses a hoist rope system and a dragline to raise and lower the claw and move it back and forth. The dragline excavator is ideal for underwater projects due to its use of a pulley system instead of a hydraulic actuator.
Suction Excavators
Comprise of a 30-cm-diameter suction pipe used for small or fragile digging jobs, debris cleanup, and underground projects. Its gentler nature provides a low chance of damaging surrounding areas unlike the standard hydraulic excavator.
