what is remote control grab?
Remote control grab is an efficient tool for loading and unloading bulk cargoes. It closes when lifted by the crane hook and can be opened remotely while suspended in the air – without requiring any additional power supply.
Its hydraulic and electrical components adopt a plug-in modular design, facilitating easy maintenance and repair, and making it well-suited for ocean-going vessels.
Why use a remote control grab?
Higher Operation Precision and Lower Material Loss
Remote control enables accurate positioning during grabbing and discharging, significantly reducing human operating errors. It improves overall operation precision and prevents material collision and spillage to minimize cargo loss.
Enhanced Operation Safety and Full Compliance
Operators can control the grab remotely from a safe zone without standing close to the working area, fundamentally reducing safety hazards and injury risks. The equipment fully complies with on-site safety management regulations.
Flexible Adaptability and Smooth Operation in Complex Sites
Remote operation eliminates restrictions imposed by narrow spaces. It supports dragging and material picking even in confined areas, adapts to various changeable working environments, and delivers stable performance under complex operating conditions.
Shorter Operation Cycles and Higher Throughput
No manual auxiliary intervention is required throughout the process. The grabbing and discharging workflow is highly efficient and continuous, drastically shortening single-cycle time and increasing cargo throughput and overall productivity.
Streamlined Manpower Allocation and Reduced Operating Costs
Fewer operators are required per unit. This optimizes on-site staffing and labor allocation, effectively cutting labor expenses over the long term and enabling large-scale low-cost operation.
Comprehensive Optimized Material Handling Capacity
The specially optimized structure allows stable and safe grabbing and lifting of all types of bulk materials, expanding the range of cargoes that can be handled safely.
Strong Universal Compatibility and Maximized Utilization
With excellent compatibility, the grab quickly adapts to materials of varying densities and forms, as well as diverse working scenarios. It maintains stable performance under all working conditions and greatly boosts overall equipment utilization efficiency.
How it does to work?
---Opening Cycle:
Press the controller switch, send the message to the receiver, then the electromagnetism valve open the hydraulic circuit system, the hydraulic vat was extended because of the gravity of goods and down roof beam, the down roof beam was separated from moving board, to make the grab open , and the grab can do the next closing cycle.
---Closing Cycle:
When the grab is opening, the moving board is connecting with top roof beam, and separate with down roof beam, at that time, the hydraulic circuit system is opening, and the piston of hydraulic vat was pulled out by moving board. When grab the goods, the hook of the crane go down, the moving board go down along the hydraulic vat with the piston of the cylinder, when the moving board touch the stroke switch on the down roof beam, the stroke switch stop the electromagnetism valve to stop the hydraulic oil . The hook of the crane goes up with moving board and down roof beam, to make the grab close.
Remote control grab buffer design:
The throttle valve controls the oil flowrate, so that the initial opening speed of the grab is slow (within 3seconds) to avoid mechanical shock; then accelerates to complete the unloading.
