Hydraulic Grab & Mechanical Grab

Hydraulic grab and mechanical grab have the following characteristics on a clamshell crane:

Hydraulic Grab:

Flexibility: Controlled by a hydraulic system, easy operation, and precise control.
High Power: A hydraulic system provides strong power, suitable for handling large materials or tasks requiring high force.
High Automation: Capable of automated control, enhancing operational efficiency.
Versatility: Adjustable to different job requirements, with a wide range of applications.
Higher maintenance costs: Regular maintenance of the hydraulic system is necessary, leading to relatively higher maintenance costs.
Mechanical Grab:

Simple Structure: Mechanical grabs have a comparatively simple structure, resulting in lower maintenance costs.
Wide Applicability: Suitable for general loading and unloading of materials like earth and stones.
Manual Operation: More manual operation is required compared to hydraulic grabs.
Lower force output: Mechanical grabs may have lower force output compared to hydraulic grabs, suitable for general loading and unloading tasks.
Considering the operational requirements and budget constraints, choosing between a hydraulic grab and a mechanical grab depends on their respective advantages and suitable applications
