What is the difference between a mechanical and hydraulic type grapple?
One of the key decisions to make is whether you need the mechanical or the hydraulic grapple for the excavator.
Mechanical Grapple:
Mechanical grapples utilize the bucket cylinder to perform the operations. It does so when the cylinder’s opening movement opens up the jaw’s tines.
The mechanical grapples need less maintenance compared to hydraulic grapples.
Now, the question remains; what kind of job is most suited to a mechanical grapple? Well, the stiff arm attached to the dipper arm of a mechanical grapple can lift the huge weight, move around the scrap, and be a perfect fit for heavier jobs.
Hydraulic Grapples:
On the other hand, hydraulic grab gets all the energy from the excavator. The hydraulic circuit of the machine is attached with the grapple jaws, which move the tines in synchronization. The hydraulic grabs for excavators are considered more efficient and precise in movement.
Hydraulic Grapples can even move at an angle of 180-degrees to provide you complete freedom of action on the job site. So, we can say that hydraulic grapples are meant for freedom of movement and precision.
After reviewing the significant contributing factors, you can now decide what sort of grapple is appropriate for the task you will accomplish. Whether it’s the construction site where you need to move the heavy stones or the demolition site where you need to clear the debris off the site, the excavator grapple attachments let you maximize the productivity on site.
