Grab overhead crane is equipped with grab as its lifting spreader, maintaining almost the same structure as standard overhead crane but featuring a different lifting mechanism. Zomax grab overhead crane is precisely and reliably designed and deliver continuous, safe and efficient handling for grabbing and lifting tasks in a variety of challenging and demanding environments.
Our grab overhead crane are available in both single and double girder configurations, with diverse grab shapes and different grab bucket opening and closing drive mechanism to meet specific material handling needs and application requirements. We offers three flexible control modes: manual control, semi-automatic control and fully automatic control. They allow seamless switching between modes. In any automatic mode, manual control takes precedence when needed.
A grab bucket EOT (Electric Overhead Traveling) crane functions similarly to a traditional overhead crane but features a grab spreader for material gripping and lifting. It comprises:
Grab Bucket: The core gripping tool, available in orange peel or clamshell designs, depending on the material being handled. It includes jaws, side plates, and a bottom plate.
Opening/Closing Mechanism: Can be mechanical, electric, or hydraulic, driven by motors and chains to control grab movement.
Crane Structure: Consists of main girders, end carriages, and a traveling trolley, supporting and moving the grab along the track.
Control System: Offers manual, semi-automatic, and fully automatic modes. Operators can seamlessly switch between control modes for better efficiency and positioning accuracy. Manual override is always available.

Zomax cranes are built with a robust safety system, including:
Overload protection
Hoisting motor thermal protection
Anti-collision systems
Swing control
Travel limit switches
Sound and light alarms
Circuit self-check protection
Phase failure and imbalance protection
These features minimize risks and maximize safety during high-duty operations in demanding environments.
Material Type: Determine the appropriate grab (orange peel for irregular, clamshell for granular).
Operating Environment: Ensure crane specifications match indoor/outdoor and temperature requirements (-20°C ~ +40°C).
Load Frequency & Capacity: Choose the right working class (A3–A7) for your usage.
Power Supply: Check voltage compatibility (220V to 660V, 3-phase AC).
Installation Space: Adequate clearance is needed for the trolley and grab to move efficiently.

Control System: Manages crane operations manually or automatically via buttons and remote controllers.
Zomax grab cranes is are widely used for handling bulk goods such as grain, ore, sand, scrap iron, garbage, and more commonly used in power plants, yards, workshops, docks and other locations. The grab crane has a high requirement on heat, dust, and corrosive conditions. We can offer you the optimal grab crane solutions to suit your specific needs.
There are two main types of grab buckets: the orange peel grab and the clamshell grab. The orange peel grab is ideal for handling materials such as steel scrap, big iron stock, garbage, and steel mills whereas the clamshell grab is used to lift small bulk materials such as grain, bulk fertilizer, etc.
The Grab Overhead Crane is ideal for industries such as:
Steel & Metallurgy – transporting scrap, ore, or slag
Ports & Shipping – unloading bulk cargo like coal, sand, and grain
Waste Management – handling refuse and recyclables
Mining & Quarrying – moving gravel, rocks, and minerals
Construction Sites – lifting loose materials
Zomax grab cranes are designed for durability and ease of maintenance:
Modular components reduce downtime during repairs
Durable grab mechanisms resist wear and tear in abrasive environments
Service-friendly layout allows fast inspection and maintenance access
Preventive maintenance ensures long-term cost-efficiency and reliability
