The Wireless Radio Remote Control Grab adapts to all working sites, requiring only a simple connection before operation. No extra accessories need to be installed on marine cranes.
The grab grips materials close to the crane wire ropes, and its opening action can be easily controlled via remote operation – simply press the "Open" button on the radio transmitter at any time during hoisting.
The grab delivers labor-free operation. Equipped with high-capacity rechargeable lithium batteries, it guarantees reliable continuous operation for up to 72 hours on a single charge.
When loaded with bulk cargo, the grab's opening/closing movement can be paused at any stage by pressing the corresponding button. The grab will resume its opening procedure once the "Open" button is pressed again.
Multiple lip designs are available to suit various cargo types. Grabbing capacity can be adjusted to accommodate bulk materials with different stacking densities.
This grab achieves approximately 80% of the working efficiency of electro-hydraulic grabs, yet its price is less than half that of an electro-hydraulic grab.
Operating System
The grab operates via oil circulation between cylinders and hydraulic manifolds. Its solenoid valve is controlled by the wireless remote transmitter and powered by two 12V dry batteries.The opening action is triggered remotely, while the closing action relies on lifting force from the shore crane. No electric motor or hydraulic pump is required for operation.
Smooth Opening System
The smooth opening system features exclusive technology designed to deliver shock‑free operation, effectively extending crane service life. When the operator presses the open button, the ENJUE grab begins to open slowly, with the opening speed gradually increasing.
Extreme Battery Endurance
The ENJUE grab delivers up to 400 hours of continuous operation under 24‑hour nonstop duty, without the need for battery charging or replacement.
Easy Installation and Assembly
Compatible with all crane types, this grab comes as a complete package with all necessary accessories for immediate use. No additional fittings – such as cable reel systems or chains – are required. Simply attach it to the crane hook and the grab is ready for operation.
Grab Volume Capacity Adjustment
By reducing the grab capacity to lower the bucket lip height, the unit maintains optimal material picking performance – making it particularly suitable for efficient handling of bulk materials with varying densities.
Partial Opening Function
The ENJUE grab features a partial opening function, which allows the operator to remotely control horizontal partial opening via the radio transmitter.
Special Wear-Resistant Steel
The lips of ENJUE grabs are fabricated from high-quality Swedish 500HB steel, delivering outstanding wear resistance and excellent leak-proof performance.
Heavy-Duty Central Hydraulic Cylinder
The central cylinder is mounted above the grab arm and delivers multiple advantages: it eliminates side deflection during bulk material handling, prevents cylinder bending, and provides full protection to the piston rod when the grab is in the parked position. It operates with a grab opening angle ranging from 50° to 60°.
Q1:What is the areas using remote control grab?
It handles bulk cargo at ports, ships, mines, grain yards and factory warehouses.
Q2:How to choose the effecient size?
Select grab volume based on your crane lifting capacity and bulk material density.
Q3:Which cranes are suitable to using remote control grab?
All rope-type cranes like ship, port and overhead cranes can work with it without extra fittings.
Q4:What is a remote control grab?
It is a battery-powered wireless grab closed by crane lift and opened via radio remote.
