Requires regular maintenance

Can be affected by temperature changes

Requires a compatible

Working principle of Excavator mechanical grapple

Mechanical excavator rotating grapples operate using a mechanical linkage system. They are designed to open and close using mechanical force, allowing them to grip and release objects. Mechanical grapples can be further classified into two types, namely, fixed and rotating grapples.

Advantages 

Lower initial cost  grapples

Less maintenance required

Resistant to temperature changes   

Can be used with non-hydraulic excavators force 

Disadvantages

Lower gripping force compared to hydraulic 

Cannot handle certain types of materials

Limited operating speed
