Process and material handling
Overhead cranes with grabs
A crane and grab system designed for the site, for moving bulk materials, feeding processes and storage.
The application decides
Crane, grab and control form a single system
Sizing a grab crane takes into account the material properties, required volume, frequency of use, travel distances and the process environment. The grab design and the crane’s duty class are matched to the same task.
Typical applications
- Waste and biofuels
- Bulk material storage
- Process feeding
- Sorting and pre-processing
Site-specific system
Two-jaw hydraulic grab
A hydraulic grab suited to efficient handling of bulk materials. The jaw shape, volume and materials are selected to suit the material being handled.
- Grab geometry to suit the material
- Crane capacity includes the grab’s own weight
- Duty class sized by the work cycle
- Control and motion paths matched to the process
System components
Key system components
A working system requires the crane, control and power supply to be sized for the same usage and environment.
Overhead crane
Single or double girder crane according to capacity, span and duty class.
Radio remote control
Clear view of the working area for the operator, with control functions matched to the process.
Power supply
Conductor rail or cable system to suit the crane’s movements and installation environment.
Note on equipment selection
The grab’s payload is lower than the crane’s rated load, because the grab’s own weight is part of the total lifted load. Sizing is always based on the grab, the material and the work cycle.
Shall we design a grab crane for your process?
Tell us the material, target throughput, working area and available space. We will size the crane and grab system based on these.
