Working principle of excavator hydraulic grapple
Operate using the hydraulic power of the excavator hydraulic system. They are designed to open and close using hydraulic cylinders, allowing them to grasp and release objects.
Advantages
High gripping force
Ability to handle various types of materials
Faster operating speed
Ability to rotate 360 degrees
Easy to install and remove
Disadvantages
High initial cost
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
Limited control over the grip
Cannot rotate 360 degree
The Importance of Choosing the Right Grapple Type
Choosing the right grapple for your project is critical to ensuring productivity, safety and cost-effectiveness. Mismatched grapples can lead to project delays, increased maintenance costs, and even accidents. When selecting a grapple type, project requirements, excavator compatibility, budget constraints and maintenance considerations must be considered.
